Question

Three application of centre of gravity in agriculture

Answer 1

Three application of centre of gravity in agriculture are

1.) Soil physical degradation.

2.) Gas production in soils .

3.) Emission to the atmosphere.

Explanation:

• Physical deterioration of soil involves the destruction of soil structure, dispersion of soil particles, sealing of pores, compression and increasing density, consolidation, compaction and reduced root penetration, low infiltration, waterlogging and runoff, and accelerated erosion

• The primary soil gases are nitrogen, carbon dioxide and oxygen.

• Some environmental contaminants below ground produce gas which diffuses through the soil such as from landfill wastes, mining activities, and contamination by petroleum hydrocarbons which produce volatile organic compounds.

• Atmospheric emissions are one of the most important causes of diffuse pollution, and contaminants emitted into the atmosphere may reach the soil due to wet or dry deposition of particles, at a rate dependent on their size and density.
