To maintain this balance at the required level, you can by adding various fertilizers. What is the fertiliser? Fertilizers – are substances used to improve plant nutrition, soil properties, and to increase the harvest. This essay will be about the description of the soils; types of fertilisers and reasons for using them; a description of a specific use of fertilisers to solve a soil quality problem.
Generally soil is composed of:
1. Mineral oil (50-60% of total)
2. The organic substance (5-10%)
3. Air (15-25%)

 Sandy - The size of grains are divided into classes : very large ( more than 3.5 mm) and large ( 3.0-3.5 mm ), medium ( 2.0-2.5 mm ) , small ( 1.5-2.0 mm ), very small ( 1.0-1.5 mm ) , thin ( 0.7-1.0 mm ), very thin ( 0.7 mm). Sand is the only type of soil that has the largest particles in compare with other five types of soil.
 Silty- contains proteins, fats, carbohydrates, nitrogen, phosphorus, bacteria Coli per 1g of dry substance. However, the composition silt depends on the composition of the wastewater, the purification schemes and other factors.
 Clay- when it is wet it will stick to your hands but when it is dry it won’t. Here are the main minerals that clay contains: kaolinite, andalusite, kyanite and sillimanite, halloysite, gibbsite, diasporas, aluminum oxide, monotermit, montmorillonite, muscovite, nacrite, pyrophyllite.
 Peaty- is hard to be mixed with water, but once it is done it would be a nice soil for the plant growth. It also has the acidic water which ‘fights’ w...
