Have you ever looked at the soil in your garden and considered it as anything more than soil? If not you should because there’s much more there than meets the eye. It performs many functions that you have good quality soil in your garden and might not be aware of is essential for your plants. Functions of Soil. The most immediately apparent purpose of soil is a medium. It provides support both physically and biologically. Physical support is provided by allowing the plant to grow its roots throughout the soil. Biological support is provided with its capacity to hold nutrients and water that the plant needs. It also supports other types of life also. Insects and microorganisms reside in the soil and they in turn help plant life by helping to 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 atmosphere. Cosmetic thing refers to the inorganic components in the soil e.g. stones, gravel and makes up to 40%-60% of its volume. Kinds of Soil Texture. Texture is described as the size distribution of mineral particles that were different. Clay soil comprises a high proportion of clay particles and feels lumpy to the touch. The small size of the clay particles means that they clump together readily and there is less room for air spaces. Consequently, clay soils have poor drainage and do not hold nutrients. Silty Soil feels smooth to the touch and contains a high proportion of particles. This soil is a soil because of the size of the particles allowing space for water to permeate. This soil holds nutrients more readily than clay soil as a result of spaces. It is easy to cultivate but may be compacted.
Sandy soil contains a high percentage of sand particles and feels gritty to the touch, Allows for lots of space in between particles and as a result is quite free draining. This has its disadvantages however as it doesn’t hold water and nutrients that are essential can get washed away. Loamy soil is the best type of soil texture you can have in your backyard. This is dirt whose properties are controlled by the proportions of sand, silt and clay particles. It’s well drained but does not drop water easily as is the case with sandy and sometimes silty soils. What Makes a Soil Healthy? Soil must be fertile and have a structure that is good. For a soil to be fertile it must have a pH value at a level for the plants that will reside inside and nutrients. Nutrients that should be available are the nutrients nitrogen and phosphorous for health.
