Land capability refers to the potential of a piece of land to support various types of land use and development, given its physical and environmental characteristics. It assesses how well land can sustain different activities such as agriculture, forestry, urban development, or conservation, considering factors like soil quality, topography, climate, and water resources.

Nitrogen cycle is the process where nitrogen is broken down into several chemical forms in the environment.

Nitrogen undergoes several microbial transformations during decomposition of plants and animals’ residues which are important in making nitrogen available for plants and their growth and other organisms. The transformation process is vital in maintaining the balance of nitrogen in the ecosystem. A very small percentage of atmospheric nitrogen is biologically fixed as nitrogen and other compounds of nitrogen in plants and microorganisms.

Soil is a dynamic natural body composed of mineral and organic materials, living forms as well as air in which plants grow.
