Abstract

Agricultural application of anaerobic digestates can play an important role in plant nutrition. The effects of digestate treatment were studied in pot experiments, using sandy and loamy textured soils with distinct characteristics. Three different treatments were studied and compared: control, digestate, and irrigation treatments. Nitrogen loading was calculated on the bases of the digestate analysis. The same amounts of digestate and irrigation water were applied in the different treatments before sowing and at the V4–V6 stages of maize. Besides the conventional soil chemical analysis, invertase, dehydrogenase, catalase, and the abundance of some cultivable microbes were measured in two consecutive years. According to our results, irrigation and digestate treatments had greater impact in the case of sandy soils than in loamy textured soils. Digestate provides more effective phosphorus and potassium sources than nitrogen. Based on the results of discriminant analysis, the digestate application had a greater influence on soil chemical properties, followed by microbiological parameters.
