The scientific study of soil is called pedology. Soil is composed of both organic and inorganic matter, and it is essential for life on earth to exist. The soil type that i have studied is brown earths. Brown earths are the most common soil type in Ireland and are very fertile. Soils are a composition of mineral particles 45% , organic matter 5% , air 25% , and water 25% .
Mineral Particles:
Mineral particles are the largest ingredient and make up approx 45% of soils . They are the original rock that got broken down by weathering and erosion to form the basis of soil. The type of rock that was broken down to form it is called the parent rock. The broken down rock produces minerals such as calcium, phosphorus, and potassium in the soil on which the plants feed. The parent material influences the soil colour, depth, texture and ph valueOrganic Matter:
Organic matter is decayed vegetation that is broken down by micro organisms in the soil to form humus . Humus is a dark jelly like substance that binds the soil together and improves its texture. It increases the soils ability to retain moisture. Brown earths develop in area of deciduous woodland where there is an abundance of plant litter available to decay. Brown earth soils are also found where temperatures average zero for less than 3 months of the year and rarely exceed 21 degrees. These conditions allow for microorganisms to thrive. The colour of the soil is an indication of the amount of organic material it contains with darker soils having more organic content. Humus is plentiful in brown earthsTexture:
Texture is how a sol feels when you touch it. The proportions of sand silt and clay determines the soils texture. The texture determines how well moisture and roots can penetrate the soil and how well excess moisture can drain away. The ideal combination for soil texture is roughly 40% sand, 40% silt, and 20% clay creating what is known as a loam soil. Brown earths fall into this category. They have a well-developed crumb structure which allows water air and organisms pass through it easily, and roots can spread out in it easily. Water retention is good as it is soaked up by the crumbs of the soil and nutrient retention is good also. They also have good drainage and aeration properties. Loam soils such as brown earths are ideal for cultivationLeaving Certificate Geography

Four characteristics of arid soil are :
1. They are sandy in texture and saline in nature .
2. They are having low humus content due to high temperatures .
3. Kanker has occupied in the lower horizons of this soil due to increasing calcium content downwards.
4. The soil ranges from red to brown in colour..
Hope it helps ....
