The influence of nitrogen and phosphorus chemical fertilizers applied for a long period upon some chemical and physical properties of brown-reddish luvic soil, under irrigation

This experiment began in 1975 on a brown-reddish luvic soil of reduced fertility (near 2 % humus) and pH values (in water) between 5,6-5,8 which was slightly supplied with mobile phosphorus (8-9 ppm) and middle supplied with assimilating potassium (80-100 ppm). A balanced application of chemical fer...

Summary:This experiment began in 1975 on a brown-reddish luvic soil of reduced fertility (near 2 % humus) and pH values (in water) between 5,6-5,8 which was slightly supplied with mobile phosphorus (8-9 ppm) and middle supplied with assimilating potassium (80-100 ppm). A balanced application of chemical fertilizers like nitrogen and phosphorus between 1975-1992, to the basal dressing of a corresponding calcination improved the soil fertility due to a favourable increase of chemical and physical parameters characteristic for the fertility of soil
