The aim of the respective investigations carried out on light soil in 1972-1974 was to determine the effect of sprinkler irrigation and high mineral fertilization level on physical, chemical and biological properties of soil. It has been proved that the above measures applied resulted in an increase of water resrve in the soil profile, of bulk density of the upper soil layer as well as in a decrease...
Field experiments were done in the years 1978-1980 at the Agricultural Experi ment Station Lipki on a sandy soil and at the Agricultural Experiment Station Ostoja on a Sandy loam soil. It was found that application of high mineral fetrilization and sprinkling irrigation caused an increase of potatoes yield on the sandy soil by 118% and on the sandy loam soil by 84%. Irrigation increased the wa ter's...
Field experiments were done in the years 1978-1980 on a sandy soil at the Agricultural Experiment Station Lipki and on a sandy loam soil at the Agricultural Experiment Station Ostoja. Effects of sprinkling irrigation and mineral fetrilization on the yield and water management of sugar beets were studied. It was found that application of supplemental irrigation and high rates of mineral fertilizers...
