Farmers's wisdom of soil taxonomy and fertility management dynamics is based on trial and error, problem solving and group approach to manage the natural resources. The farmers' knowledge of defining the soil taxonomy and fertility management practices is compatible to their adaptive skills and rich source of location-specific ecological information.

Measurement of unsaturated hydraulic conductivity in vadose zone is a very difficult task. It is estimated using mathematical or empirical relations. The unsaturated hydraulilc conductivity with respect to water content or suction is estimated using standard empirical relations. These empirical relations use saturated hydraulic conductivity (Ks) as one of the parameters.

The downside of using combine harvesters

The rice-wheat annual double cropping system occupies an estimated 0.5 million hectares in Nepal where it provides food for about 23 million people. Current production levels of both rice and wheat are far below their reported potential with N-deficiency being the major production constraint.

The paper describes the effect of rains on vegetal cover, different traditional practices and soil properties in the dry and monsoon period. Seven landuse systems i.e. open pine forests, tea plantation, rainfed agriculture, degraded land, grassland, recently restored site and a bare land were identified in the Bhetagad watershed of the Central Himalaya.

Rice (Oryza sativa L.)

an unprecedented study may force certain countries to do some soul searching. Contrary to what a few policy makers advocate, the study reveals that high levels of atmospheric carbon dioxide (co2)

Fertilisers boost plant growth but imbalanced application soon leads to use-fatigue

Agricultural growth in India has always laboured under the burden of producing more. The idea was: grow only foodgrains. That meant: not ecologically adapted cereals such as millets, but rice and
