摘要
The invention relates to a method for reducing the phosphorus and heavy metal load imposed on lakes and waterways by farmlands, especially clayey framlands. In the method, the natural flow paths of water from farmlands to lakes and waterways are blocked by means of a zone formed between the farmlands and the waters, the soil mass of the zone being treated with a substance improving the water permeability and crumb structure of the soil in such a way that the treated soil retains efficiently the erosion material, phosphorus compounds and heavy metals contained in the water.
