It provides support both biologically and physically. Physical support is provided by allowing the plant to cultivate its roots through the soil to hold itself in place. Support is provided with its capacity. Additionally, it supports other types of life as well. Insects and microorganisms live in the soil and they subsequently help vegetation by helping decay organic material and adding structure to the soil.

What’s Soil Made of? The four major components of soil are mineral matter, organic matter (humus), water and air. Cosmetic thing refers to the inorganic elements in the soil e.g. stones, gravel and constitutes up to 40%-60% of its volume. Kinds of Soil Texture. Texture is defined as the size distribution of different mineral particles. Clay soil feels lumpy to the touch and contains a high proportion of clay particles. The small size of the clay particles means that they clump together quite readily and there is less room for air spaces. Consequently, clay soils don’t hold nutrients and have poor drainage. Silty Soil feels smooth to the touch and contains a high percentage of silt particles. This soil is a well-drained soil due to the size of the particles allowing space for water to permeate.
This soil holds nutrients more easily than clay soil due to the spaces. It’s easy to cultivate but may be compacted. Sandy soil comprises a high proportion of sand particles and feels gritty to the touch, Allows for a lot of space between particles and because of this is very free draining. This has its drawbacks as it does not hold water and nutrients can get washed away. Loamy soil is. This is soil whose properties are controlled by the percentages of silt clay and sand particles. It is well drained but doesn’t drop water too easily as is the case with sandy and sometimes silty soils. What Makes a Soil Healthy? Soil must be fertile and have a structure. For a soil it must have nutrients and a pH value at a recommended level for the plants which will reside in it. Are the crucial nutrients nitrogen and phosphorous for health.
