Toelichting (Engels) For the opposite yield effects of biodynamic spray preparations (yield increase at higher yield levels and yield decrease at lower levels) a significant linear regression is calculated, based on data from different experiments with cereals, carrots, beetroots and potatoes. Previous explanations are discussed (normalization of yields or compensation for non-optimal nutrient supply) and a new model is suggested
