The combined effect of fertilizing with different forms of organic fertilizer The' IOSDV field experiment, testing mineral‐nitrogen fertilizer in combination with different forms of organic manure over a period of 6 years (two crop‐rotation cycles) has provided specific results concerning the interaction of the components of fertilizers. Stable manure had an intensive effect on sugar beet but only a weak effect on winter wheat. Sugar‐beet leaves had a strong effect on winter wheat but little effect on winter barley. Straw ‐green manure showed a growing effect on winter barley. As expected, the effect of fertilizing is influenced by climatic factors. Yield curves with the specific parameters ‘M’, ‘m’ and ‘i’ show – as would be expected – that the effect of the organic manure on yield is chiefly expressed at lower levels of mineral‐nitrogen manure. In this way, the curves indicate the optimal level of N‐fertilization. The balance of nutrients show that organic variances have different effects on the N‐balance. The interval evaluation shows the importance of long‐term experiments.
