How can I create, edit and use nutrition plans?

Create nutrition plans

 

To create a nutrition plan, please follow these steps:

 

  1. Open Atfarm.
  2. Select your farm.
  3. Click on NUTRITION PLAN in the left navigation bar. If the option to create a nutrition plan is not available for a specific field, the region or crop type are not supported yet. Please read here to check if your crops and region are supported.
  4. The nutrition plan overview opens. Select the field to create the nutrition plan for from the list and click CREATE A NEW NUTRITION PLAN. You can also use the search bar to search for your field.NP-UK-overview.png
  5. Enter recommendation name and add the required crop and soil data (input fields vary based on crop type and region of the field). Select if regional default values or your own soil analysis values from the soil summary should be used in the nutrition plan calculation. You can also add one or more organic fertiliser. To delete a product, click on the bin symbol. To change the unit, click on the unit next to the quantity.NP-UK-creation.png
  6. When finished, click CREATE A NUTRITION PLAN. Click CANCEL to stop this process.
  7. Your nutrition plan opens, and you can see the recommended nutrient demand and fertiliser supply for each growth stage to reach the target yield, edit the plan and add products.

 

The nutrition plan can also be created from the field page by following these steps:

 

  1. Open Atfarm.
  2. Select your farm.
  3. Select your field.
  4. Click GET RECOMMENDATION.
  5. Select NUTRITION PLAN.

 

 

Edit and use nutrition plans

 

Your created nutrition plans can be found either in the field page or in the nutrition plan overview to be reviewed and edited.

 

The nutrition plan contains the following outputs:

 

 

You can adjust your nutrition plan directly after generating or any time later with these editing options:

 

 

 

Total fertiliser supply and demand

 

The amount of nutrients needed and supplied by mineral and organic fertilisers based on the composition of all applied products for the whole crop cycle is shown in this section.

 

The fertiliser nutrient demand values indicate the crop's nutrient needs, considering the crop's demand or uptake required for the indicated productivity and the soil available nutrients.

 

The fertiliser nutrient supply values define the total nutrients supplied during the entire crop cycle, partially by the supply of mineral fertilisers and partially by organic fertilisers (if applied to the field).

To show the nutrient supply for each growth stage, click on the GROWTH STAGES tab next to the column.

 

Micro nutrients can be displayed by toggling the navigation switch next to the chart.

 

The fertiliser supply and demand can also be presented in a chart by toggling the navigation switch above the table.

 

NP-UK-tot.f.a.d.2.png

 

The graph indicates whether there is a nutrient over- or undersupply compared to the optimal nutrient demand for the entire crop cycle.

 

  • 100 % = nutrient supply from products matches nutrient demand for full crop cycle
  • >100 % = oversupply of nutrients from products
  • <100 % = undersupply of nutrients from products
  • 0 = nutrient demand not considered for quality or crop growth according to Atfarm
  • grey bar = nutrients are provided by products, but supply is higher than demand

 

To explore individual values for each nutrient and check if demand is matched, hover over each bar.

 

 

Add, modify, and delete organic products

 

The total amount of organic fertiliser applied is listed in a table below the total fertiliser supply and demand overview. The table also shows the quantity applied per hectare and needed for the entire field. By hovering over the product symbol, you can see what percentage of each nutrient is in the product.

 

You can add organic products and adapt the quantity or delete products by following these steps:

 

  1. Click on EDIT PRODUCTS below the table.NP-UK-tot.org.f.1.png
  2. Now you can enter a new value for the quantity or delete a product by clicking on the bin symbol next to the row.NP-UK-tot.org.f.2.png
  3. Click on ADD PRODUCTS to add products.NP-UK-tot.org.f.3.png
  4. A product selector opens. Search for solid and liquid organic fertilisers by scrolling through the list or using the search filter on the right side. You can filter for product family and name and also set the exact percentages of the nutrients. To clear the filters, click CLEAR FILTERS.NP-UK_add_org.p..png
  5. Click on one or more products in the list to select them.
  6. Click OK to add the selected products to the nutrition plan. Click CANCEL to stop this process.
  7. The selected products will appear in the overview of organic fertiliser applied. Enter the quantity applied.
  8. Click UPDATE in the lower blue bar to update your calculation. Click DISCARD CHANGES to remove your added products.
  9. A window for confirmation opens. Click CONFIRM to start the recalculation. Click CANCEL to remove your added products.

 

Since the organic supply is an input used to generate a nutrition plan recommendation, modifying organic products will automatically recalculate the nutrition plan.

 

 

Fertiliser demand for growth cycle and growth stages

 

In this section, you see an overview divided into two tabs: TOTAL FERTILISERS and GROWTH STAGES. The TOTAL FERTILISERS tab shows product suggestions and the amount of which needed for the entire growth cycle to reach the target yield. By hovering over the product symbol, you can see how much of each nutrient is contained in the product.

 

NP-UK-tot.f.1.png

 

To see fertiliser supply and nutrient demand per growth stage and get product suggestions for each growth stage, click on the GROWTH STAGES tab. Select a growth stage by clicking on the corresponding graphic and get a product and quantities suggestion for the chosen growth stage (growth stages vary depending on the crop type).

 

Also indicated are crop's nutrient needs and total nutrients supplied for each growth stage. The balance shows the difference between nutrient supply and demand. A value of 0 or more indicates a nutrient surplus. A value of less than 0 indicates a nutrient deficit.

 

By toggling the navigation switch on the right side, you can switch between macro- and micronutrients.

 

NP-UK-tot.f.2.png

 

This overview can also be presented in a chart by toggling the navigation switch above the table.

 

NP-UK-tot.f.3.png

 

The graph indicates whether there is a nutrient over- or undersupply compared to the optimal nutrient demand for the particular growth stage.

 

  • 100 % = nutrient supply from the products matches nutrient demand for full crop cycle
  • >100 % = oversupply of nutrients from the products
  • <100 % = undersupply of nutrients from the products
  • 0 = nutrient demand not considered for quality or crop growth according to Atfarm
  • grey bar = nutrients are provided by the product, but supply is greater than demand

 

To explore individual values for each nutrient and check if demand is matched, hover over each bar. The different colours of the bars define the product recommendations listed below.

 

 

Add, modify, and delete mineral products

 

Product suggestions for mineral fertilisers can be found under the table. By hovering over the product symbol, you can see how much of each nutrient is contained in the product.

 

You can add other mineral Yara and generic/commodity products, remove products and adjust the quantity for the selected growth stage by following these steps:

 

  1. Click EDIT PRODUCTS below the table.NP-UK-tot.f.add_pr.1.png
  2. Now you can enter a new value for the quantity or delete a product by clicking on the bin symbol next to the row.NP-UK-tot.f.add_pr.2.png
  3. Click ADD PRODUCTS to add products.NP-UK-tot.f.add_pr.3.png
  4. A product selector opens. Search for solid, liquid and foliar mineral fertilisers by scrolling through the list or using the search filter on the right side. You can filter for product family and name and set the exact percentages of the nutrients. To clear the filters, click CLEAR FILTERS.NP-UK-tot.org.f.add_pr.4.png
  5. Click on one or more products in the list to select them.
  6. Click OK to add the selected products to the growth stage. Click CANCEL to stop this process.
  7. The selected products will appear in the product table. Enter the quantity applied.
  8. Click UPDATE in the lower blue bar to update your calculation. Click DISCARD CHANGES to remove your added products.
  9. A window for confirmation opens. Click CONFIRM to start the recalculation. Click CANCEL to remove your added products.

 

Please note:

  • If mineral products are edited for one particular growth stage, other growth stages are not recalculated.
  • The nutrition plans do not account for local legal limitations. Please check your local directives and guidelines and adjust our suggestions accordingly.

 

 

Soil nutrient interpretations

 

Soil analysis data from your field or Atfarm soil data for your region is used to generate the nutrition plan.

 

We use default soil analysis values to generate the nutrition plan at first, but if you add your own soil analysis values, a soil nutrient interpretation based on the soil nutrient levels can be calculated. This contributes to the productivity of your crop and overall nutrient needs.

 

The soil analysis nutrient values can be found at the bottom of your nutrition plan in the LEARN MORE section under SOIL ANALYSIS NUTRIENT VALUES.

 

NP-UK-soil_a.n.val..png

 

 

Add and modify regional Atfarm soil values

 

Please note:

You can only modify the regional Atfarm soil values. If you used your own soil summary for nutrition plan creation, you cannot modify it since this is aggregated. To update a value, you need to add a new record for the latest sample date.

 

Atfarm does not necessarily provide an interpretation for each nutrient. If no soil analysis values have been provided, you still can edit the values and enter them manually by following these steps:

 

  1. Click EDIT under soil analysis in the header of the nutrition plan. You can also edit the values in the LEARN MORE section at the end of the nutrition plan by clicking on SOIL ANALYSIS NUTRIENT VALUES and then EDIT.NP-UK-soil_a.n.val.edit1.png
  2. The soil analysis results open. The results are divided in primary and secondary parameters.
  3. In the field VALUE enter primary parameters such as pH, organic material and macro nutrients and secondary parameters such as micro nutrients, cation exchange capacity or sand, clay and loam content. To change the unit of a parameter, click on the unit.
  4. Select the measuring method used to determine the value of a parameter by clicking on the METHOD dropdown. The method values vary from country to country.NP-UK-tot.org.f.add_pr.5.png
  5. When finished, scroll down and click SAVE. Click CANCEL to discard the changes.

 

Since soil analysis values are used as an input to the calculation of the nutrition plan recommendation, any modifications will result in a recalculation of the nutrition plan.

 

 

Total quantity of products required

 

At the bottom of the nutrition plan you can find a product list of fertilisers used in the nutrition plan indicating the total quantity of products required to apply this nutrition plan based on the field size.

 

Click on FERTILISER SUPPLY AND DEMAND in the LEARN MORE section to see the details including a summary of mineral and organic fertiliser amounts in both application rate per hectare and total amount for the farm.

Adjust original crop and soil input parameters

 

To modify original input parameters entered in the nutrition plan creation, scroll down to the end of the nutrition plan and click on INPUT PARAMETERS in the LEARN MORE section. Adjust the crop and soil data by clicking EDIT.

 

NP-UK-inputs.png

 

Enter the desired value for the particular parameter and click SAVE when finished.

 

Since these parameters are used as an input to the calculation of the nutrition plan recommendation, any modifications will result in a recalculation of the nutrition plan and may change the suggested products and quantities.
