KINDS OF FERTILIZERS AND HOW TO APPLY THEM
Fertilizer is anything added to the soil that will increase the yield of the crops. It is used primarily to increase the available nutrients in the soil in order to balance the plant-nutrient ratio.
1. Organic fertilizers
These are derived from decaying plant and animal products such as blood meal, bone meal, manure, plant parts, and leftovers.
a) Animal manure
It increases the absorptive power of the soil and improves the physical condition of the soil. It stimulates biochemical activity and supplies nutrients to the plants.
b) Green manure
These are the green, growing plants that are plowed under. Upon their decomposition, the plant food they contain becomes available to other plants.
c) Compost
This is an organic material consisting of very fine, thoroughly rotted manure, plant parts, and other organic matter. The process of changing plant and animal waste into the simplest form of organic material is called composting.
A compost heap or pile is necessary to every farmer or gardener for it is a means of utilizing to the best advantage all the waste materials from the farm crops and animals.

This lecture explores the various kinds of fertilisers, focusing on their definitions, purposes, and applications in agriculture. We will delve into organic fertilisers, including their sources and benefits for soil health, as well as the methods for creating effective compost heaps. Additionally, we will examine inorganic fertilisers, discussing their types and appropriate application techniques tailored to specific crops and growth stages. This session aims to enhance understanding of...
