potassium removal was the most significant, then nitrogen, phosphorus, calcium were in descending order

In a course of the research there was studied the crop rotation productivity and nitrogen, phosphorus and potassium balance in cropping on sod–podzolic sandy loam and loamy soil. The research was realized in the conditions of the Republic of Belarus in 2004-2010 on sod-podzolic sandy loam, developing a powerful loess soil in the SEC ‘Schemyslitsa’ Minsk district and sod-podzolic sandy loam, underlain at a depth of 30-50 cm of sand, soil in the State Enterprise ‘Experimental Base named after Suvorov’ in Uzda region. As a result of research it was revealed that average annual grain-grass rotation productivity on sod-podzolic loamy soil during lower phosphorus fertilization at 70 kg/ha and potassium fertilization at 20 kg/ha on 8.2–12.8 h of f.u./ha was higher than at the sod-podzolic sandy loam. Total nutrients removal with yields increased with increasing of fertilizer doses
