Regulation of mineral nutrition of agricultural crops in precision farming

The article demonstrates the effectiveness of precision farming in the regulation of plant mineral nutrition, using corn as an example. Variable rate fertilizer application should be based on soil agrochemical analysis data from fields, yield planning, and forecasting. Essential indicators for planning include the content of organic matter, pH, nitrogen, phosphorus, potassium, individual meso and microelements, and cation exchange capacity. It has been proven that in the conditions of the Left–Bank Forest–Steppe on areas with Chernic chernozems on loess like loams with a high potassium content, it is possible to apply reduced rates of potassium containing fertilizers or omit them entirely, thus conserving resources and achieving the goal of precision farming equalize grain yield across the field.
