A further significant finding is the widespread nature of soil fertility problems in the watershed . Since there is considerable litter transfer from forests to agriculture, soil fertility in the forest is the poorest, followed by shrub and grazing land. Only irrigated land has an adequate nutrient status for sustained production, and higher nutrient inputs are needed in all other parts of the watershed. Most of the sediments are coming out of degraded lands and not well-managed agricultural terrace land as documented from erosion plots and hydrological stations. It is necessary to replicate research across the Hindu Kush-Himalayas following a common methodology, for policy formulation and guidance on natural resources' management and rehabilitation of degraded land.
Water is as important an issue as soil.
Co-ordination is needed in any research programme, at the local and governmental level, for the unimpeded implementation and continuity of research. There must be a common methodology and strict adherence to scientific principles in order to produce results which have wide replicability. At present, the new site is at the planning stage. The following publications are available on the research done on the watershed. Schreier, H., P. B. Shah and G. Kennedy.
