What is the active ingredient
All fertilizer doses are calculated per active ingredient. Here are useful formulas for converting various elements into active ingredients: ➡️ Phosphorus (P) = phosphorus pentoxide (P2O5) × 0,436➡️ Potassium (K) = potassium oxide (K2O) × 0,830➡️ Calcium (Ca) = calcium oxide (CaO) × 0,715➡️ Magnesium (Mg) = magnesium oxide (MgO) × 0,603➡️ Sodium (Na) = sodium oxide (Na2O) × 0,742➡️ Sulfur (S) = sulfur trioxide (SO3) × 0,400 Remember that only the following elements need to be calculated:P- P2O5K-K2OCa-CaOMg-MgOS-SO3

Phosphorus in soil
The following conclusions have been drawn from numerous phosphate fertiliser experiments: The absorption of phosphate fertiliser by crops planted immediately after application is low, Typically, 10 to 30% of the phosphorus from 100% fertiliser is immediately available. The loss of applied phosphorus with running water is very low. When spreading over the soil surface, most of the phosphorus that is not incorporated into the crop remains in the first 2-3 centimetres of soil. Ploughing in the soil allows for a…

The fifth principle of healthy soil: Integrate livestock production
Historically, animals, plants and soils have been energetically linked. In recent years, however, animals have played a lesser role due to confined spaces and the shrinking number of farms. Grazing in the spring or autumn results in the conversion of high-carbon crop residues into low-carbon organic matter, which balances the carbon-nitrogen ratio. Grazing livestock on annual or perennial pastures for short periods of time, followed by a long recovery period, allows plants to grow back and accumulate sunlight and carbon…

WHAT ADDITIONAL INFORMATION IS REQUIRED TO RECEIVE RECOMMENDATIONS?
For a standard laboratory analysis, you need to know the planned yield of three different crops (if you do not clearly understand the crop to be grown next season) or one crop with three different yield options (if the crop is clear but the grower wants to compare costs for each planned yield). Any additional information will also be useful, such as information on the presence or absence of irrigation, rainfall in the region where the fields are located, last year's predecessor crops and their yields, and more.
-
WHAT SHOULD I DO IF THE PLANTS IN ONE AREA OF MY FIELD LOOK GREEN AND HEALTHY, BUT IN ANOTHER?
For comparative analysis, we recommend that plant samples be taken from each of these sites. It is also useful to include in the comments all information about management practices in these areas (if there were any differences). After harvesting, soil samples are also recommended to be taken separately from each plot.
-
DO I HAVE TO PAY SEPARATELY FOR RECOMMENDATIONS?
No, because the fee for recommendations is included in the total cost of conducting a full comprehensive agrochemical analysis.
