Extra information:

Manure is organic matter that is used as fertilizer by farmers to increase agriculture. Some examples are cattle dung, urine, crop wastes, domestic wastes, weeds like water hyacinth, by-products of agricultural industries, droppings of goat and sheep, slaughterhouse wastes like bone meal, blood meal, horn and hoof meal, fish wastes, etc.

They are eco-friendly and harmless. It maintains the texture and fertility of the soil. Chemical fertilizers destroy the natural composition of soil and have an adverse effect on human health.

Composting helps farmers. They don't need to buy costly fertilizers from outside as composting can be done easily at home.
