Guides and manuals



Including EAMU documents when publishing recommendations

Gatekeeper agronomists with a Sentinel Active subscription can now automatically send EAMU documents as an email attachment at the same time as publishing a recommendation to a grower’s Gatekeeper.

To send the relevant EAMU document(s) when publishing a recommendation:

  • Create your recommendation as usual
  • Use the ‘Publish Gatekeeper plan’ button
  • Select contact(s) and settings as usual
  • Tick ‘Email linked EAMU PDF documents’
  • Continue as normal

Synchronise or send/receive as usual, and your contact will receive an email with PDF attachment(s).

Using agronomy packs in recommendations

For details on using agronomy packs in recommendations, including setting them up in catalogues and sending ag packs in orders, please click here.

Site Supervisor

For details on using site supervisor, please click here.


How to backup to an alternate location

It is strongly recommended that data local users have a robust backup policy which includes regularly saving a copy of their Gatekeeper backup to an external media source to mitigate against data loss. Data secure users should also consider a similar approach.

Gatekeeper automatically creates a backup on the local machine during the synchronisation process. To create a backup in an alternate location:

  • From the main Gatekeeper screen, click ‘Synchronise’
  • In the ‘Backup Options’ section, select ‘Alternate’
  • Click ‘Browse’
  • Navigate to required alternate location (USB or other external drive, etc) and click ‘OK’
  • Click ‘Synchronise’

When to synchronise Gatekeeper

Gatekeeper should be synchronised after every data entry session.

Your data is the most important aspect of your business – it is important to regularly ensure that you have a valid backup of your data that has been placed on to an EXTERNAL media (such as a USB Drive). For help with this please call support on 01594 545 022.

Users with more than one site should synchronise before entering any data to pick up any changes the other user has made and after data entry is complete to backup your data and make the amended data available to other users.

If you are not using Gatekeeper on a regular basis then we recommend that Gatekeeper is synchronised once a month to keep the program up to date.

Crop nutrition

Verification options for fertiliser jobs

For users who have created or imported a nutrient management plan, there are a number of options for how fertiliser jobs are verified against the plan.

These options are found on the ‘Plan’ tab of any planning jobs, or the ‘Options’ tab of recording jobs, and are controlled by tick boxes:

‘User defined nutrient verification’ checks the job against any product extra checks or field protocols created by users.

‘Nutrient Management verifying’ checks the job against the calculated nutrient management requirements (RB209 figures but not NVZ rules).

‘NMax verifying’ checks the job against any calculated NVZ figures (NVZ rules only).

Managing sulphur in a nutrient management plan

When sulphur is included in a nutrient management plan (NMP), users may find that it causes a verification failure. This is because typically the amount of sulphur applied to arable crops (often in an N:S product) exceeds the requirement calculated by the RB209. There are a number of possible resolutions which you may find useful, and these are detailed below.

Please remember before proceeding that Farmplan cannot provide agronomic advice. The notes below explain how the program works, and are not an agronomic endorsement of any approach. Use of the nutrient management module and ensuring any plans created are appropriate remains at all times the responsibility of the user.

Option 1 – Don’t include sulphur when creating the nutrient management plan

The failure is caused by the fact that the amount of sulphur applied has exceeded the requirement calculated. If you do not include sulphur when creating the plan, there is no maximum allowed amount calculated, so no exceedance is possible.

Once an NMP has been created in a cropping year, it is not possible to delete the plan or remove nutrients, so this option is not a solution where a plan has already been created including sulphur.

Option 2 – Include sulphur in the plan, and edit the requirement figure

If you wish to include sulphur in your NMP, but you intend to apply a greater amount than calculated by RB209, then you may wish to manually edit the sulphur requirement after it is calculated. After using the RB209 integration to create the NMP, use the edit option to adjust the sulphur figures. For more information on editing an NMP, please see page 21 of the nutrient management guide books (England and Wales or Scotland).

Option 3 – Adjust your verification settings

Sulphur is only checked as part of verification where the option ‘Include Nutrient Management verifying’ is ticked. The verification status of a plan job is controlled via the ‘Plan’ tab; and of a recording job via the ‘Options’ tab.

Choosing a ruleset in the nutrient management centre

There are currently two RB209 rulesets available for use in Gatekeeper. The appropriate ruleset to use depends on your location, cropping, and preference.

Users in England and Wales can chose to use the new version 9 of the RB209, referring to the new AHDB document and calculations, which requires an active internet connection. Alternatively you may prefer to keep using version 8 of RB209, utilising the PLANET system, which has been available through Gatekeeper for a number of years. Please note that at present, grass fields must be calculated using RB209 v8.

Users in Scotland should select the Scotland specific selection from the available list.

Adding fertiliser analysis details

When adding a fertiliser product to Gatekeeper, it is necessary to add the nutrient contents of the product. Once this has been done, nutrients applied can be automatically calculated from the amounts of product applied, or conversely amounts of fertiliser required can be calculated from nutrient figures.

To add analysis to an existing fertiliser:

  • From the main Gatekeeper screen, go to Setup > Products (Business)
  • Navigate the list on the left through Variable Costs > Nutrition > Fertiliser and click on the fertiliser name
  • Click on the ‘Nutrition’ subtab
  • Click ‘Add Item’
  • Select the nutrient required (e.g., N)
  • Enter the nutrient content of the fertiliser (e.g, 34)
  • If required, click ‘Add Item’ again and repeat to add the next nutrient. It’s not necessary to add nutrients with a 0 analysis – for example, for 0:24:24, just add P2O5 and K2O.

This information must be entered if you will be using the nutrient management centre.

Adding manure analysis details

When adding a manure product to Gatekeeper, it is necessary to link the product type and nutrient contents to the product. Once this has been done, the nutrients applied can be automatically calculated from the tonnage of manure applied to the field.

To add analysis to an existing manure product:

  • From the main Gatekeeper screen, go to Setup > Products (Business)
  • Navigate the list on the left through Variable Costs > Nutrition > Organic Manure and click on the manure name
  • Click on the ‘Nutrition’ subtab
  • In the ‘Manure type’ dropdown, tick the white box to activate the dropdown list and select the appropriate type for your product
  • On the ‘Total’ tab on the right hand side, select from the available nutrient management rulesets, and standard figures will be populated.
  • Optional: if you wish to override the standard figures, tick ‘Override analysis’ and enter your own figures
  • Optional for V9 England and Wales ruleset use: if you wish to add ‘Available’ figures to display on the ‘Fertiliser’ tab of field records,
    • Tick ‘Override analysis’ on the ‘Total’ tab
    • Go to the ‘Available’ tab
    • Click ‘Add Item’, select nutrient, and enter available figure as required. Repeat as necessary for additional nutrients.

This information must be entered if you will be using the nutrient management centre.

Using the nutrient management centre

Gatekeeper’s nutrient management centre allows users to create nutrient management plans based on their existing field records.

Alternatively, you may wish to import a nutrient management plan from your agronomist.

Once a nutrient management plan has been created, it can be used to quickly and easily create fertiliser jobs through the season.

Crop years and year end

Cropping year

The cropping year in Gatekeeper normally refers to the harvest year of the crop being planted. For example, a winter wheat crop sown in the autumn of 2020 would be harvested in 2021, so Gatekeeper would refer to this as the 2021 crop year.

The cropping year you are currently working in is visible in the top right corner of Gatekeeper, and the current cropping year will be shown in green. Previous years are yellow and then red, and future years are purple, When you are ready to move into the next year, you will need to ‘Advance the cropping year’. For further information, see the FAQ below. Advancing the cropping year does not prevent you from continuing to add information into previous cropping years.

Where two crops are grown in a single cropping year (for example, a cover crop followed by a spring cereal) the crop sequence function should be used. For more information see the FAQ below on multiple crops in one year.

Multi update option for cropping

By popular request – there is new functionality in Gatekeeper to allow users to update the cropping for multiple fields at the same time. You can find the ‘Multi Update’ button within the Cropping Summary window, or click here for guidance notes.

Top tip: users with many fields may wish to use multi update to first make all arable cropping records ‘Unallocated’, and then work through the list adding the new year’s cropping, to make it more obvious which fields have had their new crop added.

Non plan year message

This message displays when the year selected is a Plan year. A plan year is signified by the business selector in the top right hand corner of Gatekeeper being coloured purple. It is not possible to enter any records into a plan year apart from the intended crop.

If you wish to start entering data into a Purple/Plan year then please follow the instructions on how to advance the cropping year.

Please note, you can create a Nutrient Management Plan in a Purple/Plan year.

Multiple crops in one year

Click here for notes that can be downloaded.

For intensive cropping, such as field vegetables, the intensive cropping module may be more suitable. Please contact support on 01594 545022 if you want to discuss this.

Importing recommendations from my agronomist who is using Muddy Boots software

Your agronomist will need to email their recommendations as an XML file. This can then be imported into Gatekeeper.

The procedure for importing into Gatekeeper is:

  • Save the XML attachment from your email to an easy to find location (eg C:/users/desktop).
  • Open the Planning module and click the Import button.
  • Ensure the File Format selected is ‘Third Party GK XML File’.
  • Click the browse button (small square with 3 dots) and locate the XML file, then click Import.
  • We recommend that you use the Importing Plan Option of ‘Do NOT Change Field and cropping data’. This this will prevent any errors in your agronomists field details changing your field details.
  • Click the import button and the recommendation will display as a draft plan.

Seed dressing used on a field

It is very difficult to record the amount of seed dressing used on a field as the quantities involved are so small and it is normally pre-applied to the seed being sown.

Therefore the easiest way to record the seed dressing is to add a note to the planting job on the Notes tab. Alternatively create a new ‘Field Diary Notes’ job in recording.

Select the fields (or click on the Notes tab in an existing job), select the correct date and a heading of ‘Traceability Notes’ and in the comment box enter the seed dressing type and any additional notes you require.

Once a note has been entered under the Traceability heading it can be included in your traceability reports. This information is also available in the analysis module under the ‘Diary notes’ area.

Recording weather

To record weather click the Business button

Select the ‘Weather’ tab, then the required tab e.g. Rainfall. Click ‘Add Item’ and enter the date and value of the record, then press enter to add another line for the following day.

If you wish to add multiple records e.g. rainfall, temperature and wind at the same time then click ‘Pick Headings’ and select additional headings to add to the grid.

Soil sampling results

To record soil sample results click Recording, Add Job, select the New Job Type as Field Sampling then click the Add Field Sampling Job button.

Select the sampled fields and move them to the right, click OK, then select the required nutrients e.g. P, K, Mg and click OK.

The results of the sampling can then be entered into the grid.

Sampling results from major UK labs can be imported directly into Gatekeeper to save data entry time. For more information please contact us.

NB The above instructions do not apply to spatial data.

Home saved seed

Home saved seed is dealt with by entering the ‘sale’ of the home saved seed followed by its ‘purchase’.

Recording the Sale
To record the financial benefit from the ‘sale’ of home saved seed, enter a sales invoice recording the relevant quantity and price.
NB If you create a new product for this purpose (eg ‘Home saved wheat seed’) ensure that this product is set up within ‘Outputs’ (as below) and recorded against the harvested field(s) as well as the sales invoice.

Recording the Purchase
A purchase invoice ‘buying’ the seed at the required price should now be entered, it can then be applied to the relevant fields.
NB The product used on the purchase invoice and any planting jobs must be within the ‘Variable Costs’, ‘Seed / Plants’ area (as below)

Entering data in multiple years

Data will be entered into the crop year shown by the Main Business and Year Selector (brightly coloured rectangle in the top corner of Gatekeeper).

To view or enter data to a different crop year, click the Main Business and Year Selector then select the required year from the tree view (as below).

NB Any information accidentally entered into the wrong crop year will need to be deleted and re-entered into the correct year.

Copying a previous job

To create a new job by copying a previous job (or Template or Budget Job) click ‘Recording’, ‘Add Job’, and select ‘Copying from the selected job / template job’.
Select the job to be copied from the list displayed. A summary of the job is shown and the level of detail to be copied to the new job can be selected. After ‘Copy Field Operation Job’ is clicked the job can be edited as required.


Measuring a field

To measure the area inside a field boundary, from a mapping window:

  • Ensure the correct field boundary layer is on top
  • Select the active tools menu on the left hand side
  • Select the measuring polygon tool (octagon with measuring tape)
  • Right click inside the field and select ‘Find complex polygon’
  • Right click again and select ‘Finish this entity’

The field size will be shown in the ‘Area’ box of the measurements section of the active tools menu. It is also possible to freehand draw a shape to measure the area of, or use the headland measuring or parallel line measuring tools to measure length and area of other field characteristics.

Please note: the area of the field boundary in the mapping module does not have to match the area of the field in the cropping record.

Deleting a field boundary

It is not possible to delete a field boundary once one has been created. However, if you wish to disassociate a boundary from the current cropping record, you can change the region attached to the cropping record:

  • Open the cropping record for the field in question
  • Select the ‘Region’ subtab
  • Select ‘Swap Field Region’
  • Select ‘Setup Field Regions’
  • Select ‘Add Whole Field Region’ or ‘Add Part Field Region’ as appropriate. Rename the new or old regions as required, then ‘OK’ to close.

The role of field regions in managing field boundaries

The field region forms the link between the field boundary and the cropping record. If you change a field’s boundary, it will change the boundary for that field in every cropping year where the cropping record is linked to the same region.

If you wish to make a change to the field boundary that only applies to certain years, or from the current year forwards, it is necessary to change the field region before making any changes to the field boundary.

This is also the case if you are importing new field boundaries captured with precision farming equipment, and want to update the records from the current year onwards, without affecting previous years.

Click here for a document containing instructions on changing the field region.

The difference between whole field and cropping year boundaries

All field records in Gatekeeper have the capacity to be split into multiple cropping records – this is frequently used to reflect the fact that one field may be growing more than one crop, or have a crop plus environmental area.

To reflect this in the mapping module, every field has the capacity to hold two types of boundary. The ‘whole field’ boundary is the entirety of the field including any cropping splits; ‘cropping year’ boundary is the different parts of the field which combine to make one parcel.

If you do not have any split cropping records, the ‘whole field’ and ‘cropping year’ boundaries are exactly the same, and changing one will change the other.

Once a field contains split cropping records, the ‘whole field’ and ‘cropping year’ boundaries will be different. In this case, changing one will not result in a change in the other.

Both whole field and cropping year boundaries are managed between years by the field region (for more information please click here).

Adding or editing field boundaries

The following links provide information on adding and editing field boundaries in Gatekeeper mapping.

We advise all our customers to take care before editing existing field boundaries, or importing boundaries to fields which already have boundaries. It is possible to impact the boundary data of multiple years if the correct steps are not taken before editing or importing. For further assistance please don’t hesitate to contact the support team who will be happy to make sure you have the correct plan for your circumstances.

OS data

If you wish to use Ordnance Survey data in your Gatekeeper Farm Mapping module this can come in different forms with different levels of detail.

We recommend that you firstly contact the Gatekeeper Support team on 01594 545022 and request the OS Open data (under a free license) for your farm which we can provide in 10km x 10km tiles. This will provide you with the following features in Gatekeeper Mapping:

  • Administrative Boundary
  • Height
  • Natural Feature Area
  • Natural Feature Line
  • Railway Line
  • Road Line
  • Settlement Area
  • Settlement Line
  • Text
  • Tidal Boundary

Please note this data does not include field boundaries; if you require OS boundary information you will need to purchase Master Map data in either a Shape or DXF format. is one of several companies which are able to supply OS data in this format.

All Gatekeeper mapping users have the ability to view a backdrop image (which includes some boundaries) from Bing based on 1:25 000 OS data by selecting the layers icon, ensuring the ‘MS Bing Maps Backdrop’ box is ticked then selecting ‘Ordnance Survey’.

Plotting tools in Farm Mapping

There are two reasons for this:

  1. Plotting tools do not display if a map scale greater than 1:30000 is selected.
  2. If you wish to plot or measure from the Ordnance Survey layer supplied by Bing you will need to activate the full Bing mapping module. (Users with the ability to import field boundaries from GPS equipment may find this option more useful for their mapping needs).The upgrade from Bing light access carries a minimal licensing cost: for more information please contact Farmplan on 01594 545022.

Importing RPA boundaries to Gatekeeper

Customers in England have the ability to import their RPA field boundaries to the mapping module; either as a cartographic layer, or as cropping record field boundaries. For more information, please click here.

Sentinel & verification

What is Sentinel?

Sentinel is an information library for Gatekeeper users. It contains information on plant protection products, as well as wider industry information such as recommended lists, RB209 information, and an extensive photo library of common weeds, pests, and diseases.

Sentinel Viewer comes as standard with all Gatekeeper sites; users may view limited library information and benefit from product pick lists when adding new products.

Sentinel Active is a subscription option which gives access to the full product library including product approvals, and the Sentinel Active verification system. Sentinel verification checks your planned use of registered plant protection products against their allowed uses, and gives you a traffic light result for peace of mind.

For more information on Sentinel, please click here for a download document.

Please note, Sentinel Active subscriptions are effective per site, not per organisation. For more information about Sentinel Active, please contact us on (01594) 545000

Viewing product information

The Sentinel library contains a wealth of information – you can find product details, recommended lists, RB209 information, and more.

To navigate the library, open the Sentinel module, and use the tree view on the left hand side to navigate the contents

For details of a specific product, you may wish to use the search function – please see ‘Searching the Sentinel library’

Viewing product labels

Sentinel contains product labels which have been made available to us – the library is extensive but not comprehensive.

To view a product label, you can:

Navigate Sentinel library using the the tree view:

  • From the list on the left hand side, select
    • Plant Protection Products
    • Product Guides
    • The product manufacturer
    • The product type (e.g., ‘Herbicides’)
    • The product name

Use the search functionality in the Sentinel library:

  • From the Sentinel home page, click the Search function
  • Enter the name of the product you wish to view
  • Ensure the ‘Search by’ function has ‘Name/tag’ selected
  • Click ‘Search’ or hit return
  • If a product label is available, the product name will be visible as a link under ‘Topics’

View the label while creating or editing a plan or recommendation:

  • Write the plan/rec as usual
  • Select the ‘Products’ tab
  • Click ‘View Product Label’
  • If you are not taken to the product label, the system does not currently contain that record.

Can I add my own conditions to verification?

Verification in Gatekeeper is a combination of a number of elements:

  1. Sentinel verification (for Sentinel Active subscribers), where a plan includes a registered plant protection product
  2. Nutrient management verification, where a plan uses a fertiliser and a nutrient management plan is in place
  3. Product extra checks
  4. Field protocols

Sentinel verification cannot be edited by users.

The level of nutrient management verification can be selected at the plan level; for more details please see ‘Verification options for fertiliser jobs‘.

Product extra checks and field protocols are both user-defined options which can be set at the business, site, or organisation level, and allow users to enter their own conditions to form part of the verification process. For further information, please contact support or see the Sentinel and verification user guide.

The user can set up Gatekeeper to record stock quantities or not.

To record the amount used and unit price ONLY, the following approach can be adopted on a heading by heading basis.

The example below uses the ‘Fertiliser’ heading.

Click Setup / Headings then select Variable costs / Nutrition / Fertiliser / Fertiliser.

Change the ‘Stock Mode for Current Stock Period’ to ‘Price list’ and save.

Products within the ‘Fertiliser’ heading will no longer display an in stock quantity, neither will invoices need to be entered for any product within the ‘Fertiliser’ heading.

To enter a product price for the current stock period click Setup / Products(Business), select the product name (within the changed heading) and enter the desired price in the ‘Actual Price’ box.

Setting up one implement with different settings

It is possible to set up an implement with different settings, eg you may wish to record that the sprayer application rates can be 100l/ha and 200l/ha.

To enable the the recording of implements click Tools/Options then within ‘Business’ select ‘Field Jobs’ and tick the ‘Record implements used for Planning and Recording jobs’ box.

To add an implement click Setup/Implements and Settings, then ‘Add Implement’. Select the correct category, type the implement name, and select the correct Sub-category. Click ‘Add Setting’ and enter a name eg 100l/ha. Repeat to enter additional settings.

If you wish a cost to be incurred whenever this setting is selected, tick the ‘Use machinery cost’ box and select the desired cost from the list.

To enter a sprayer capacity and application rate tick the ‘Use capacities’ and the ‘Apply as tank mix’ boxes. Enter the ‘Primary capacity’ (and ‘Secondary capacity’ for a twin tank sprayer) and the planned application rate in the ‘Tank mix volume rate / ha’ box. Select the ‘Spray quality’ and ‘LERAP star rating’ from the list.

When an implement setting is used in a plan it will be displayed in the operator instructions.
