Have you ever looked at the soil in your garden and considered it as anything more than soil? If not you should because there is much more there than meets the eye. It performs many functions that you might not be aware of and have good quality soil in your garden is crucial for your plants. Functions of Soil. The most apparent purpose of soil is a medium to support plant life. It provides support both biologically and physically. Physical support is provided by allowing the plant to grow its roots through the soil. Support is provided with its capacity to hold nutrients and water the plant needs. Additionally, it supports other kinds of life also. Microorganisms and insects reside in the soil and they in turn help plant life by adding structure to the soil and helping decay organic material.

What is Soil Made of? The four important components of soil are mineral matter, organic matter (humus), water and atmosphere. Mineral matter refers to the inorganic elements in the dirt e.g. stones, gravel and constitutes up to 40%-60% of its volume. Different Types of Soil Texture. Texture is described as the size distribution of mineral particles that were different. Clay soil feels lumpy to the touch and comprises a high proportion of clay particles. The small size of the clay particles means that they clump together and there is room for air spaces. Clay soils have poor drainage and do not hold nutrients. Silty Soil contains a high proportion of silt particles and feels smooth to the touch. This soil is a well-drained soil due to the size of the particles allowing space for water to permeate.
This dirt holds nutrients more readily than clay soil as a result of spaces. It is easy to cultivate but may be compacted. Sandy soil comprises a high percentage of sand particles and feels gritty to the touch, Allows for lots of space in between particles and because of this is quite free draining. This has its drawbacks however as it doesn’t hold water and nutrients that are essential can get washed away. Loamy soil is. This is dirt whose properties are controlled by the percentages of sand, silt and clay particles. It is well drained but does not 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 good structure. For a soil to be fertile it must have nutrients accessible and a pH value at a recommended level. Are the nutrients nitrogen and phosphorous for overall health.
