Abstract
Abstract: Ammonium fertilizer has an acidifying effect in soil that improves the plant availability of manganese (Mn), and the effect is most pronounced for band‐applied fertilizer. About 60% of the nitrogen (N) in animal slurries is ammonium‐N, and in livestock intensive areas the crop N requirement is fulfilled by animal slurry. To avoid N loss from surface‐applied slurry, direct injection in bands is desired but this application method is not common practice. However, slurry also contains alkaline reacting agents that may counteract the acidifying effect of ammonium. The aim of this study was to determine the Mn availability as affected by slurry type and application method.Two slurries, low and high in carbonate, were applied in spring by trailing hoses and direct injection in a winter barley crop, which is the crop most susceptible to Mn deficiency under Danish conditions. Mineral reference plots receiving nitrate and ammonium fertilizers were included. The differing quality of the two slurries did not affect the Mn off‐take and crop growth significantly. Only the ammonium treatment had a positive effect, but the treatment was not able to remedy the Mn deficiency. The possibility of remedying Mn deficiency in winter barley through the choice of N source for spring application seems to be limited.
