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 have good quality soil in your garden and may not be aware of is crucial for your plants. Functions of Soil. The most apparent function of soil is a medium to support vegetation. 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 ability to hold nutrients and water that the plant needs. It also supports other types of life as well. Insects and microorganisms live in the soil and they in turn aid vegetation by helping decay organic material and adding structure. What's Soil Made of? The four important 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 makes up to 40%-60% of its volume. Kinds of Soil Texture. Soil texture is described as the size distribution of mineral particles that were different. Clay soil feels lumpy to the touch and comprises a high percentage of clay particles. The size of the clay particles means that they clump together and there is less room for air spaces.

Clay soils do not hold nutrients and have poor drainage. Silty Soil comprises a high percentage of particles and feels smooth to the touch. This soil is a 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 is easy to cultivate but can be compacted quite readily. Sandy soil contains a high percentage of sand particles and feels gritty to the touch, Allows for a lot of space in between particles and as a result is quite free draining. This has its drawbacks as it doesn't hold water and essential nutrients can get washed away. Loamy soil is. This is dirt whose properties are controlled equally by the percentages of clay, silt and sand particles. It's well drained but doesn't lose water readily 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 and a pH value at a level. Are the nutrients nitrogen and phosphorous for health.
