All created Nutrition Plans can be found in the Nutrition Plan overview, which can be accessed from the left navigation bar in the Atfarm web app. Nutrition Plans created for a field can also be found on the field page under Recommendations.

The Nutrition Plan contains several sections with customizable information on mineral fertilizer, organic fertilizer, soil analysis and more.

1. Click Edit next to the estimated target yield.
2. Enter a new value in the input field. Click the unit dropdown to select the unit.
3. Click Save changes to save your edits.
4. The Nutrition Plan will be recalculated immediately.

Product plan – adjust mineral products

The product plan shows products and their quantity recommended for each growth stage, which can be filtered by soil and foliar application.

Hover over a product name to view its nutrient composition. Hover over a product quantity to view macro and micro nutrients supplied at that growth stage by the product.

1. Click Edit product plan in the top right corner.
2. Enter a new quantity in the input field next to a product. Click the unit dropdown to select the unit.
3. Click Save changes to save your edits.
4. The Nutrition Plan will be recalculated immediately.

Add mineral product

1. Click + Add product under a growth stage to access the product selector.
2. The product selector will open with a list of mineral products to choose from.
3. Use the search options on the right to
   • Filter by solid, liquid or foliar fertilizer
   • Filter by product family
   • Search by product name
   • Set the exact nutrient percentages using the sliders
4. Click on a product in the list to select it.
5. Click OK to add the selected products to the growth stage.
6. Enter the quantity to be applied in the input field next to the new product. Click the unit dropdown to select the unit.
7. Click Save changes to save your edits.
8. The Nutrition Plan will be recalculated immediately.

Delete mineral product

1. Click the bin icon next to a product to remove it from the plan.
2. Click Delete in the pop-up to confirm the deletion.
3. The Nutrition Plan will be recalculated immediately.

Product summary – adjust organic products

The summary shows all products for the field, divided into mineral and organic products. For each product, you can see the quantity required per ha and per field to reach the target yield.

Adjust organic product quantity

1. Click the Organic products tab.
2. Click Edit quantity below the product list.
3. Enter a new quantity in the input field next to a product. Click the unit dropdown to select the unit.
4. Click Save changes to save your edits.
5. The Nutrition Plan will be recalculated immediately.

Add organic product

1. Click the Organic products tab.
2. Click + Add product below the product list.
3. The product selector will open with a list of organic products to choose from.
4. Use the search options on the right to
   • Filter by solid or liquid fertilizer
   • Filter by product family
   • Search by product name
   • Set the exact nutrient percentages using the sliders
5. Click on a product in the list to select it.
6. Click OK to add the selected products to the product list.
7. Enter the quantity to be applied in the input field next to the new product.
8. Click the unit dropdown to select the unit.
9. Click Save changes to save your edits.
10. The Nutrition Plan will be recalculated immediately.

Delete organic product

1. Click the Organic products tab.
2. Click the bin icon next to a product to remove it from the plan.
3. Click Delete in the pop-up to confirm the deletion.
4. The Nutrition Plan will be recalculated immediately.

Nutrient demand and supply

The total demand and supply of macro nutrients (kg/ha) and micro nutrients (g/ha) for the field is displayed in a chart.

The chart indicates whether there is a nutrient surplus or deficit from the products' nutrient supply compared to the optimum nutrient requirement for the whole crop cycle. If a nutrient's supply and demand are 0, that nutrient's demand isn't taken into account for quality or crop growth.

The nutrient demand values indicate the nutrient needs of the crop, taking into account the uptake required by the crop for the specified productivity and the nutrients available in the soil.

The nutrient supply values define the total nutrients supplied throughout the crop cycle, partly by mineral fertilizer supply (recommended products) and partly by organic fertilizer (if applied to the field). Hover over each nutrient bar to see the composition of the mineral and organic fertilizer supply with product names and quantities.

Soil analysis interpretation

The soil parameters used to calculate the Nutrition Plan can be viewed at the end of the Nutrition Plan and include:

• Soil type
• Level, value, unit, and extraction method for each soil parameter

If you didn't use your own soil analysis values to calculate the Nutrition Plan, we used optimal default soil nutrient values for your region to calculate the nutrient demand.

The nutrient interpretations are based on available soil analysis extraction methods and units to accurately classify the soil nutrients. Not all nutrients may be used or required to build a Nutrition Plan for a particular crop type. Yara's agronomists determine how nutrients are interpreted based on best practice. If a soil nutrient value can't be interpreted, because the extraction method is not yet supported, this will be noted in your field's soil analysis summary. These values won't be considered in the Nutrition Plan.

Change soil type

1. Click the pen icon next to the soil type.
2. Select a new soil type from the dropdown.
3. Click Save to save your edits.
4. The Nutrition Plan will be recalculated immediately.

Edit nutrient values

You can adjust the default soil parameters as described below. If you've used your own soil analysis values, these can't be edited in the Nutrition Plan as they're in the aggregated soil analysis summary. To update a value, you need to add a new record for the latest sample date.

1. Click Edit nutrient values in the top right corner.
2. Enter a value for the desired parameter in the corresponding input field. Click the unit dropdown to select the unit.
3. Select the extraction method from the dropdown next to a parameter.
4. Click the unit dropdown to select the unit.
5. Click Save to save your edits.
6. The Nutrition Plan will be recalculated immediately.

Input parameters

In this last section of the Nutrition Plan, you can see the crop data you entered to calculate the Nutrition Plan.

Change parameters

1. Click Edit to open the input mask.
2. Click on an input field to edit the information.
3. Click Save to save your edits.
4. The Nutrition Plan will be recalculated immediately.
