Abstract
When soils of Sri Lanka are considered, future research needs are concentrated on environmental implications of inputs used in agriculture. It is suspected that the heavy metals and impurities introduced through fertilizers and agrochemicals are leading to many diseases as Chronic Kidney Disease of unknown etiology (CKDu). The available data is not sufficient to draw any conclusions due to lack of equipment, improper analytical methods, and insufficient number of replicates. Much research is also needed on pollution of water resources by nitrogen fertilizers and means and ways of replacing part of the requirement by biological methods.
