Describe how leaching can limit the use of land as a resource, and explain how this problem can be overcome.

In agriculture, leaching refers to the loss of water-soluble plant nutrients from thesoil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.

Use of the organic and natural fertilizers and well drainage facilities.

Explanation:

Leaching is the loss of the soil nutrient values and this is due to the rain and the irrigation systems. The structure of the soil and the cropping patterns are a major factors that influence this leaching.  It can also lead to groundwater contamination. The hazardous wastes d the dumping grounds and in agriculture the excessive use of the fertilizer and the pesticides in fields most of the nitrogen and the phosphorus fertilizers causing eutrophication.
