520			_aThis study was done in Dhading Besi area to see the effect of farmers' practices on soil fertility management over the years in Middle Mountain region of Nepal. It attempts to measure the effect of socioeconomic condition, farming system on soil fertility management, farmers' constraints and priorities under the condition of operations and change in soil fertility status such as pH, percentage of organic matter, percentage of total nitrogen, available phosphorus, potassium and texture over the years from 1978 to 1995. Based on base line data, soil samples were collected from three sites of the study area Nilkantha "A" , Sangkos and Nilkantha "B" at an elevation of 660 meters, 720 meters and 760 meters respectively. The results of analysis show that the socioeconomic conditions had significant effect on soil fertility management but farming system as such had no significant relation to soil fertility status as they were practicing similar farming system. Farmers had different priorities for inputs, services and technology under the condition of operations. Farmers had constraints regarding soil fertility management such as fertilizer technology and soil testing services. There was a change in soil fertility status over the years. The change in soil pH was negative and significant over the years in all the three sites. The texture remains same as before in all the three sites. The change in organic matter and total nitrogen were positive and significant over the years in Nilkantha "A" and Sangkos sites due to increase the application of Farm yard manure in low lands. The changes in case of Nilkantha "B" were not statistically significant. The physiography of this site is described as lower hill slope and loss of nutrients may be more than other two sites due to soil erosion. These findings show that the farmers manage their soil fertility status with their limited resources satisfactory but there is a need for better soil fertility management to keep up with the need for higher production in the future.
