Dr Sultan Ismail is the expert introduces wormi-compost and liquid fertilizer to Hulu Yam farmers. Hulu Yam Fresh is the only farmers group adopted his knowledge and practice Natural Farming in Hulu Yam.
This is what he said long ago but is what we had heard from him, ``Besides the major nutrients and trace elements, the earthworm casting are known to be a rich source of plant growth promoting substances such as auxins and cytokinins,'' explains Dr. Ismail.
Earthworms are important for healthy soils. They love to eat organic materials within the soil, so if
you find them, this means you probably have a good amount of available organic materials.
Earthworms also help to maintain healthy soil, since they will migrate to healthy soils where organic
materials are abundant. They will tunnel within the soil, devouring the organic materials, and leaving their castings (worm poo). Earthworm castings can contain as much as 10 times the amount of plant-available nutrients as the original soil.
