Results of Twenty-Four Years of Crop Rotation Research at ‘De Schreef’ Experimental Sitea clay loam soil. When potatoes were grown once every three years, every four years and every six years, the tuber yields were respectively 21, 16 and 7% lower than those of plots where potatoes were grown for the first time. Although the yield depression can partly be explained by differences in so

Twelve Years of Continuous Cropping and Short Rotations of Potato at the ‘PAGV1’ Experimental Sitebiological soil fertility on a marine loam soil in Lelystad. From 1981–1984 the net yield of potato cv. Saturna in a two-course crop rotation with sugar beet (soil fumigated every two years) was 97% of the yield of potatoes in a three-course crop rotation (soil not fumigated). With additional organi
