Cation exchange capacity (CEC) gives an insight into the fertility and nutrient retention capacity of soil. Certain soil minerals, such as clay, particularly in combination with organic matter, possess a number of electrically charged sites, which can attract and hold oppositely charged ions.

WebCation Exchange Capacity – Cation exchange capacity (CEC) is a measure of the soil’s ability to retain and supply nutrients, specifically the positively charged nutrient ions called cations. These include the cations calcium (Ca 2+ ), magnesium (Mg 2+ ), potassium (K 1+ ), ammonium (NH 4 + ), and many of the micronutrients. WebThe amount of each of the major components of soil depends on the amount of vegetation, soil compaction, and water present in the soil. A good healthy soil has sufficient air, water, minerals, and organic material to promote and sustain plant life. The typical approximate composition of soil.

WebSandy soils are those that are generally coarse textured until 50 cm depth and consequently retain few nutrients and have a low water holding capacity. Soil management practices which lead to an increase in the fine fraction are helpful in improving soil properties and crop productivity. Fertilization of these soils is considered essential.
