Variable rate application of fertilizers based on the Mehlich 3 methodology

Popis výsledku v původním jazyce

Variable rate fertilizer application adjusts plant nutrition according to the local differences in soil nutrient content and plant requirements. Traditional practices for estimation of base fertilization using soil sampling are non-effective in precisionagriculture because of inadequate spatial coverage and high cost. This paper describes the concept of variable fertilization based on soil analysis according to Mehlich 3 procedures. The first step includes obtaining information about soil agrochemicalproperties. Optimization of the soil sampling based on sensor mapping, such as remote sensing and on-the-go measurement of soil electrical conductivity, proved reduction of the total number of samples up to 60 % by keeping the same accuracy of soil mapsas a 1-ha regular grid. The second step, so called "balance coefficient" was implemented to smooth the classification of the soil nutrient maps instead of origin 5-classes categorization recommended by the Mehlich 3. In the last step, his
