Nutrition

We described Nutrition within Expert models. There we set Nutrition need within Phenology stages. As we know, Plans are usually built with expert models, so similar nutrition model from Expert models are also on Plans.

Plans are consisted of Plan orders which are similar to Expert models but with added new areas and calculated quantites not on 1 ha, but on actual CA area. Fertilizer quantities and nutrient quantites are still calculated for 1 ha.

Nutrition tab is set only for Plan order. It works similarly as Nutrition tab for Expert models. Fertilizers are copied from Tasks tab. At the moment it is not possible to change Fertilizers, but it is possible to change Fertilizer quantities within Nutrient tab.
Dashboard shows Nutrition balance for each Phenology stage, so it is clearly visible how well nutrition is managed.
Within grid it is also shown nutrition balance (within column Phenology balance for each nutrient) for each nutrient and if color settings are made it is even better represented by colors, regarding the nutrition balance values.
It is important that on tasks phenology is set because otherwise there will be no connestion between Tasks and Nutrition tab.

Reports:
a) Nutrition report for Plan order

Nutrition report for Plan order has the same structure as report for Expert models. Chosen Plan order is the one selected and marked by triangle within selecte Plan. There is taks list, yearly nutrition balance and graphs for Nutrient balance per Phenology and graphs for three macro nutrients: N, P and K.
b) Fertilization Plan

It is a complex report which replaces Fertilization Plan from previous versions of Farming. It is very important to set criteria exactly so report can meet users expectations.

For Fertilization Plan several criteria are mandatory to get any results:
- CA
- Plan id
- Date From/To

It is possible however to specify more precisely and to get even narrow results.
This is example of report:

After Nutrient balance for each Plan order, on the bottom of section for each CA, Fertilization balance for CA for chosen period is written, with nutrient addition sums, nutrient removal sums and total balance.
In the end, average year values are added. This value is a product between nutrent sums and number of years which are covered by Plan orders.

Additionally, on the top of each Plan there is, if any, the most important Soil analysis properties:
- Soil analysis date
- Phosphorus content and Phosphorus correction content
- Pottasium content and Pottasium correction content
- Humus content
- Soil type
