Effect of Fertilisation Regime on Maise Yields

Using natural fertilisers in agriculture improves quantity and quality yields. They introduce macronutrients (nitrogen, phosphorus, and potassium) and micronutrients into the soil. Enriching the soil with organic substances through fertilisation with digestates requires the farmer to have considerable knowledge and accuracy in dosing due to the need to comply with permissible concentrations of macronutrients. The availability of nutrients in a digestate is closely dependent on the substrates used in the biogas plant, and it cannot be stated unequivocally that better yields of field crops will be achieved by using it as manure. Therefore, the authors conducted a two-year study of the effect of the fertilisation method on maise yields. Based on the research carried out, the fertiliser suitability of the digest was confirmed. Plants fertilised with it were characterised by the highest (compared to other fertilisation methods) grain yield (of 12.07 Mg per hectare on average). In addition, they were characterised by adequate plant height (3.15 m on average). The observations also indicate good emergence and satisfactory early vigour.

Automated summary

Using natural fertilisers in agriculture improves quantity and quality yields, but it cannot be guaranteed that better yields of field crops will be achieved by using digestates as manure. Farmers need knowledge and accuracy in dosing when enriching the soil with organic substances to comply with permissible concentrations of macronutrients.
