Soil Nutrient Balance and Soil Fertility Status under the Influence of Fertilization in Maize-Wheat Cropping System in Nepal

Soil nutrient balance is affected by management in crops. A poor technique results an imbalance the soil status which could have a long-term negative impact on crop production. The current study was carried out to assess effect of different rates nitrogen (N), phosphorus (P), and potassium (K) maize-wheat cropping system Cambisols Khumaltar, Lalitpur, Nepal during 2019/20 2020/21. experiment included three-factor randomized complete block design with three doses each N, P, K replicated times. There remarkable change pH, organic carbon (SOC), total contents over period time application NPK. pH changed from 5.98 5.53, SOC increased 11.7 16.8 g·kg?1, N decreased 1264 1177 mg·kg?1, available P2O5 declined 214 63.6 K2O 71.7 24.8 mg·kg?1 varying NPK after four seasons. Furthermore, partial, apparent, net were predominantly all fertilizer treatments, but magnitude lower under higher positive partial noticed levels. depletion native P pools even at attributed removal as compared inputs. Therefore, continuous balanced fertilizers crucial maintaining fertility productivity
