Investigations were carried out on Podvyazny hops variety (2009) on gray forest heavy loamy soil. The paper studied the aftereffect of liming, mineral fertilizers and green manure crops on water-physical properties, agrochemical parameters of soil, productivity and the quality of hops. It was found that when plowing green manure nutrients additionally enter into the soil as green manure. In embodiments of the factor A1, there was a significant increase in the acidity of 0,09–0,20. Liming contributed to neutralize the acidity of the soil. In the first three years there was an increase in the degree of saturation and the amount of exchangeable bases. In embodiments, the reduction of nutrients continued. The ploughing of green manure crops helped increase productivity by 0,04 and 0,12 t/ha, and the effect was not significant in the current year. During liming, the yield increased by 0,23 t/ha, while the content of alpha-acids by 1,0 %.
