Soil Fertility Assessment and Mapping of Regional Agricultural Research Station, Parwanipur, Bara, Nepal

Rural Agricultural Change and Fertility Transition in Nepal.

Using longitudinal panel data from the Western Chitwan Valley of Nepal, this study investigates the impact of the use of modern farm technologies on fertility transition-specifically, the number of births in a farm household. Previous explanations for the slow pace of fertility transition in rural agricultural settings often argued that the demand for farm labor is the primary driver of high fe...

Soil Fertility Decline: Definitions and Assessment

In permanent agricultural systems, soil fertility is maintained through applications of manure, other organic materials, inorganic fertilizers, lime, the inclusion of legumes in the cropping systems, or a combination of these. In many parts of the world the availability, use, and profitability of inorganic fertilizers have been low whereas there has been an intensification of land-use and an ex...

Soil Fertility Decline on Agricultural Plantations in the Tropics

Maintaining the soil chemical fertility is a key prerequisite to sustain crop productivity in the tropics. Several studies perceive that soil fertility decline is widely spread in tropical regions and that it is caused by inadequate nutrient replenishment and high losses as compared to natural ecosystems. Although this has been recognised for some decades, there is a need for hard data on soil ...
