Question

State any two advantages of using organic fertilisers?

Answer 1

1. Organic matter improves soil structure and contributes to greater soil health. It improves the soil quality by its nutrient-holding capacities.
2. Organic fertilisers have the ability to bring beneficial organic matter to the soil, which enhances its water holding capacities (moisture retention).
3. Encourages the microbial life of the soil by healthy soil organism growth.
4. Organic fertilisers also aerate the soil by the flow of oxygen.
5. An adequate amount of organic matter in the soil can help to ensure that nutrients are available to plants on a steady basis and that the soil structure enhances root growth.
6. The majority of organic fertilisers contain insoluble nitrogen and act as slow-release fertiliser. By their nature, organic fertilisers increase physical and biological nutrient storage mechanisms in soil, lessening the chance of over-fertilisation.
7. Organic fertilizer nutrient content, solubility, and nutrient release rates are typically much lower than mineral (inorganic) fertilisers. They can utilise existing nutrients so that good growth is achieved with lower nutrient densities while wasting less and releasing nutrients at a slower, more consistent rate.
