Abstract

A key way of assessing plants’ requirements for fertilizers is field experience. It allows you to establish the effectiveness of the fertilizers used in a particular crop, to identify the relationships between the chemical compositions of the soil, plants, crops and to develop a comprehensive method for optimizing the mineral nutrition of plants. On chestnut soils, the effect of doses of nitrogen fertilizers for potatoes in the ratios 1-3:1:1 (N45-135Р45К45) was studied. Reliably obtained high increases from nitrogen at a dose of 90 kg A.I./ha concerning the control - 4.5 t/ha (14.9) was studied. Reliably obtained high increases from nitrogen at a dose of 90 kg A.I./ha concerning the control - 4.5 t/ha (14.9%) and to the background 3.1 t / ha (9.8) was studied. Reliably obtained high increases from nitrogen at a dose of 90 kg A.I./ha concerning the control - 4.5 t/ha (14.9%) and to the background 3.1 t / ha (9.8%). In all cases, the payback ranged from 0.156 to 0.25 c in the control and 0.2-0.4 c in the background (P1K1). The studies were carried out to diagnose the need for batteries on typical chestnut soils in the conditions of the Pavlodar region of Northern Kazakhstan. Below is a summary of the assessment of various dosages of nitrogen fertilizers for potatoes on the background of phosphorus-potassium nutrition.
