Detailed explanation-1: -Soils with an abundance of clay or organic matter will have a very high CEC, while soil with lots of sand or little organic matter will have a low CEC. To increase the ability of your soil to retain nutrients, the best thing to do is add organic matter such as compost.
Detailed explanation-2: -The addition of organic matter to the soil usually increases the water holding capacity of the soil. This is because the addition of organic matter increases the number of micropores and macropores in the soil either by “gluing” soil particles together or by creating favourable living conditions for soil organisms.
Detailed explanation-3: -Humus improves soil fertility by acting as a reservoir for nutrients, increasing the water holding capacity of the soil, improving soil structure and friability, and providing a source of energy for living soil organisms.
