Utilization of Different Varieties of Dried Leaves into Organic Fertilizer using Earthworms (Lumbricus terrestris) as Agents for Fast Decomposition
Chapter I
(Introduction)
A. Background of the Study
Since ancient times, farmers have known that adding certain substances to the soil helps produce healthier, more abundant crops; such a substance is called fertilizer. The researchers decided to make an organic fertilizer. Organic fertilizers are made up of organic materials such as leaves decay, they produce an excellent fertilizer. Fertilizers are also often by-products of some manufacturing process. Some organic fertilizers are waste products of living organisms. They also supply food for beneficial bacteria in the soil and improve the condition of the soil. They act more slowly than chemical fertilizers and are less likely to damage seeds and young plants. This information is adapted from “The New Book of Knowledge” Encyclopedia.
Fertilizers are compounds given to plants to promote growth; they are usually applied either through the soil, for uptake by plant roots, or by foliar feeding, for uptake through leaves. Fertilizers can be organic (composed of organic matter), or inorganic (made of simple, inorganic chemicals or minerals). They can be naturally occurring compounds such as peat or mineral deposits, or manufactured through natural processes (such as composting) or chemical processes (such as the Haber process). Fertilizers typically provide, in varying proportions, the three major plant nutrients (nitrogen, phosphorus, and potassium), the secondary plant nutrients (calcium, sulfur, magnesium), and sometimes trace elements (or micronutrients) with a role in plant nutrition: boron, chlorine, manganese, iron, zinc, copper, and molybdenum.
This new book presents recent and important research from around the globe.
Earthworms are known to significantly influence soil aggregate stability and hence to regulate
