W badaniach porównywano dynamikę zawartości potasu przyswajalnego w glebie nawożonej różnymi rodzajami nawozów organicznych (obornikiem bydlęcym w ilości 30 t·ha⁻¹, wermikompostem w ilości 10 t·ha⁻¹ i międzyplonem ścierniskowym uprawianym po przyoranej słomie jęczmiennej) na tle pięciu dawek azotu mineralnego - 0, 100, 100 + 40, 100 + 80 i 100 + 80 + 40 kg N·ha⁻¹. Stwierdzono podobną koncentrację...
В проведенных в 1979-1982 гг. опытах в опытной станции Своец около г. Вроцлава на почве хорошего ржаного комплекса исследовали влияние боронования зяблевой вспашки на выбранные физические свойства почвы и урожаи сахарной свеклы. Не были установлены более значительные различия в структуре почвы после зимнего периода между объектами с зяблевой вспашкой боронованной или оставленной в гребнях. На боронованных...
The effect of pre-winter ploughing to the depth of 15 cm, furrow turning (8- 10 cm) and spring ploughing (15 cm) on some physical properties of soil and sugar beet yields was investigated, in an experiment carried out in 1979-1982 at the Agricultural Experiment Station Swojec near Wrocław on soil of a good ryeland complex. It has been proved that the application of single furrow turning ploughing...
