Abstract

The purpose of this study was to evaluate the effect of meat and bone meal (MBM) on cultivation of winter triticale, winter oilseed rape, winter wheat and maize. The average annual yields and protein yield achieved in crop rotation were studied. The field trials were carried out in north-eastern Poland in 2006–2010. The factor was dose of MBM: 1.0, 1.5, 2.0 and 2.5 t ha^-1 year^-1 or 2.0, 3.0, 4.0 and 5.0 t ha^-1 every other year. The four-year experiment has proven that MBM is a valuable nitrogen and phosphorus fertilizer in cultivation of cereals and oilseed rape. By amendment of the tested meal into the soil it produced crop yield and protein yield similar to that achieved by mineral fertilization. However, the crude fat yield of rape was significantly higher under the influence of all the MBM doses. The yield-stimulating effect of MBM did not depend on the frequency of its application; therefore it is more convenient to apply it once every two years. Increasing MBM from 1.5 to 2.5 t ha^-1 did not significantly increase any of the four crop yields, therefore for soils that had satisfactory nutrients content, 1 or 1.5 t ha^-1 MBM is enough and increasing MBM will only increase economic burden for farmers and environmental risks.
