Effects of fermented and supplemented chicken manure on the nutrient management aspects of an apple orchard

AIt is a huge challenge for farmers worldwide to successfully increase the organic matter content of their soils and improve water balance at same time. Therefore, main aim study develop test organic-based nutrient composite materials that can be used by soil content, management parameters implement water-efficient technologies. The was performed in orchard Institute Horticultural Science University Debrecen Hungary (Debrecen-Pallag). experiment set up ten-year-old apple (Malus domestica ‘Pinova’) orchard. In trial, fermented poultry manure superabsorbent polymers (SAP) were different doses effects on properties fruit quality. Applied increased nitrate nitrogen soil. Treatments did not affect sugar fruits but significantly positively affected individual weight titratable acidity fruits.
