| Abstract:
During four consecutive years, in a field trial on ‘Bluecrop’ highbush blueberry planted in a podzolic sandy soil effects of three factors have been studied: (1) P fertilization vs P-O, (2) NKMg applications vs nil NKMg, (3) pine bark mulching versus clean cultivation. Phosphorus fertilization resulted in an increase of soil P and of foliar P content but had no influence on leaf and soil N, K, Mg level, vegetative growth or yield. Neither P nor NKMg fertilization had any effect on the mycorrhizal infection level - as described by the methods used. Mulching decreased the differences in soil and plant mineral content between fertilized and non-fertilized plots, also highly influenced yield and growth performance. | |
