Balanced mineral nutrition is the basis of a high yield. But often an agronomist determines the need for a plant in any fertilizer by external signs, “by eye”. This method is very unreliable, because the external signs of the shortcomings of various nutrition elements are similar to each other and even an experienced agronomist can easily make a mistake.

The lack of mineral nutrition causes:

Shortage of harvest
Poor harvest quality
Soil depletion
Weakening the resistance of plants to diseases
Excess nutrients in the soil
Poisoning plants
High crop production costs
Soil salinization
Blocking the assimilation of other nutrition elements.

ONLY WITH BALANCED MINERAL FOOD REACHES:

Maximum yield
High quality of harvest
Increase of soil fertility
Cost optimization

How to conduct agrochemical analysis of soil and calculation of mineral nutrition?

We break the site into cells.

Cell Size:
For field crops without irrigation: 25-30 hectares on flat terrain and 8-10 ha on complex terrain.
For vegetable crops on watering by furrows and sprinkling: 7-10 hectares
For vegetable crops on drip irrigation: 2.5-3 hectares
We select an average sample from each cell. For this, passing each cell diagonally, take soil samples every 25-30 meters from the depth of the arable layer (0-30 cm) evenly over the entire depth. All the samples are poured into the bucket. After the end of sampling from the cage, pour the contents of the bucket onto a plastic or metal sheet and mix thoroughly, after which we take 400-500 grams of soil (averaged sample).
We pack the averaged sample and fill out the label, indicating the following data:

Name of the farm,

address,

phone,

surname of the person who selected the sample,

field number,

cell number,

sampling date,

plant planned for cultivation in the current year,

crop predecessor,

planned yield ( t / ha),

irrigation method.
We send the packed samples to the Diagnostic Center for Plant Protection.
Within 14 days from the moment of accepting the order we receive the results of the soil analysis, the conclusion about the provision of soil with nutrients for the cultivation of the planned crops and finally:
PLAN OF APPLICATION OF MINERAL FERTILIZERS IN PLANT ROTATING.
To assess the quality of the soil and its suitability for growing certain crops, it is not enough to measure the content of nutrients and humus in it. You also need to know the acidity of the soil, the degree of its salinity, the levels of the content of certain toxic ions (chlorides, sulfates, carbonates …). The same measurements should be made for water used for irrigation or spraying. Employees of our laboratory in accordance with certified methods (GOST, ISO, DSTU) to determine the chemical composition of water and water extract the following methods:

Titration
Potentiometry
Turbidimetry
Conductometry
Photocolorimetry
Flame photometry
Our laboratory is equipped with the most modern instruments for carrying out all these measurements and obtaining reliable and accurate results.
