It tends to have good water drainage, good moisture retention and allows good infiltration of air and water. ADVANTAGES AND DISADVANTAGES OF MECHANIZATION Farm mechanization is the use of Farm mechanization is the use of large farm implement. This soil is very fertile and is ideal for planting and farming. Soils vary in their chemical, physical and biological characteristics. The color of the soilis another way to characterize soil. Important physical characteristics of soil structure and aggregation allow water and air to infiltrate, and roots to explore. Example: Fertile soil in India could be the alluvial soils. The table below describes the essential and beneficial elements obtained from the soil. Therefore, depending on the composition of the magma from a particular volcanic mountain, the resulting ash will have distinct amounts of soil nutrients. Soil characteristics, especially those which affect productivity, have a controlling influence on the diversity and balance of plant species on a site. Volcanic eruptions result in the expulsion of ash which is spread out across wide areas both near and far from the volcanic mountain. The nutrients in the soil are rich.

Histosols are heavy with water and organic material. Soil Porosity and Permeability. To be able to identify a fertile soil and distinguish it from a non-fertile soil, the soil must be surveyed. There are 17 essential plant nutrients, three come from air and water (carbon, oxygen, and hydrogen) and 14 come from the soil. It is in the process of surveying the soil that different soil types will be identified and possibly mapped out and its properties studied with a view to maintaining or sustaining the fertility of a fertile soil and improving the productive capacity of a less fertile soil.
