Abstract


Nutrient management in farmland is very difficult in case of the sloppy land. Upland are rainfed and sloppy land and low land where the land can be irrigate easily and there has sufficient water during monsoon season. Due to the heavy intensity of rainfall, upland top soil can be eroded very easily and that's difficult to manage soil nutrients. This study mainly focuses on fertilizer management practices by farmers and assessment of soil nutrient status between two different lands. Household survey was done in Dhuwakot VDC of Gorkha district, Nepal. For scientific analysis, soil sample collection was collected from both land (Upland and Low land). NPK, Organic matter and pH were analysis of soil nutrients in Central Department of Environmental Science laboratory. The soil sample was collected in after harvesting of crops on agriculture land in winter season.  From the overall study, 100% chemical fertilizer was used in low land at least two times per year by the farmer, however, mostly organic manure are used in upland. Soil fertility status of Nitrogen, Phosphorus, Potassium, organic matter and pH are more on upland than on low land. Phosphorus is a good nutrient content in the soil of the study area and then organic matter and nitrogen is in low to medium class. Most of the soil is acidic nature, so that its effect to the other macro-nutrients in the soil. The use of organic fertilizer may help to maintain soil fertility in the upland and higher amount of chemical fertilizer using may lead to decrease the soil nutrients in low land. So, organic fertilizer can enhance and maintain soil nutrients.
