Abstract: |
Soil Management Directorate along with Regional Soil Testing Laboratories in diferent Region under Government of Nepal has the mandate to test soil sample across the country. A report on soil fertility status of Nepal was prepared based on the result obtained from seven soil testing laboratories in the fiscal year 2070/71. In this FY, a total of 1700 soil samples were analyzed to determine the status of soil nitrogen (N), phosphorus (P2O5), potash (K2O), Organic Matter (OM) and pH. The results revealed that majority of the soil samples were found to be acidic (53%). Similarly, OM range from low to medium and majority of the samples have low content of soil nitrogen, phosphorus and potash. While comparing the soil fertility status of five development Regions of Nepal, soil pH was found to be dominated by acidic condition except for Far- Western Developmental Region. The organic matter content of the majority of the sample from Eastern Development and Far-Western Development Region was very low. While the OM content of other Region range from low to medium. The nitrogen results also range from low to medium across all the Regions. The status of phosphorus and potash is low in Eastern Region whereas low to high in other Regions. The paper also explored the average status of soil fertility of 38 districts which were mapped by Soil Management Directorate in coordination with respective District Agriculture Development Office. The status of soil nutrient content is declining throughout the nation but the rate of declining is higher in eastern part of Nepal. In this context the technologies to manage soil fertility status should be disseminated throughout the nation. The Government should facilitate to develop its manpower and appropriate technologies. |
