Sandy loam soils, permeable and airy, are the most suitable for peas; they warm up quickly in the spring, have regulated water conditions, with sufficient humus and calcium content. Soils that are too wet with a high level of groundwater, and too dry and sandy are not suitable. Peas are very sensitive to soil acidification; the pH should not be lower than 6.5 on light soils and 7.8 on heavier soils. On average, from 60 to 80 kg/ha P₂O₅, 120-140 kg/ha K₂O are used for average soil fertility. It is recommended to use nitrogen fertilization in the amount of 40-50 kg/ha before sowing. A deficiency, and particularly excess of nitrogen, causes an increase in the degree of infestation of pea plants by most pathogenic fungi causing the occurrence of fusarium wilt, powdery mildew and rust. Peas are sensitive to deficiencies of: phosphorus, magnesium, boron and molybdenum.
