Soil macronutrient balance: The role of organic amendments in sustainable agriculture
Veselina Vasileva, Mariana Hristova, Ana Katsarova, Nikolai Dinev
Abstract: The key to sustainable land management is to maintain a positive nutrient balance in the soil and preserve its fertility. The current study investigates six organic amendments - varying in type and macronutrient content, and their residual effects on soil nutrient status.
After composting, a significant increase in the content of total N, NO3-N, P2O5 and K2O is observed in all variants. Nevertheless, the soil remains poorly supplied with total N after the lettuce harvest, requiring nitrogen fertilization or supplementation for subsequent crops. A change in the soil chemical balance was observed in P2O5 and K2O contents at the end of the experiment. This indicates the application of organic amendments was beneficial in improving the ecological sustainability of the soil.
