| Mixed cropping systems with oil crops are of growing interest in organic farming. They can offer agricultural advances like competition against weeds, support against lodg¬ing and buffering of yield fluctuations. The aim of the cultivation method is to gain additional oil yields for energy or feed purposes. The reported higher land-efficiency-ratios of those mixed cropping systems should lead to higher nutrient requirements. But it is unknown if the different crops just compete for rare soil nutrients or if comple¬mentary effects in mixed cropping systems lead to higher nutrient efficiency. In a field study N-contents in plants and N uptake of diverse mixed cropping systems were compared to sole cropping systems. In linseed (Linum usitatissivum) or false... |
