Organic Fertilisers
The waste from plants and animals that breaks down to produce nutrients necessary for plant growth is known as Organic fertilizers. These include compost (rotted farm wastes like sugarcane trash, paddy straw, etc.), sewage and sludge, vermicompost (earthworm-decomposed organic matter), Green manures (undecomposed plant material), and other livestock manures. Farmyard manures are composed of dung, urine, and litter from farm animals (poultry, sheep, and goat sweepings). Although they are administered in vast volumes, these organic manures only contain a small percentage of the nutrients. Organic farming is the process of cultivating crops without using chemical pesticides or herbicides and solely using organic fertilizers. In addition to providing nutrients, organic fertilizers enhance the physical characteristics of the soil, boost the availability of other nutrients, and manage worms and fungi that parasitize plants.
