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 might not be aware of is essential for your plants. Functions of Soil. The most immediately apparent function of soil is a medium to support vegetation. It provides support both biologically and physically. Physical support is provided by allowing the plant to grow its roots throughout the soil to hold itself in place. Biological support is provided with its capacity to hold nutrients and water the plant needs. Additionally, it supports other types of life as well. Microorganisms and insects live by adding structure to the soil and helping to decay organic material. Are you looking about biological management in organic farming?

What’s 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 soil e.g. stones, gravel and makes up to 40%-60% of its volume. Different Kinds of Soil Texture. Texture is defined as the size distribution of different mineral particles. Clay soil contains a high percentage of clay particles and feels lumpy to the touch. The clay particles’ small size means that they clump together and there is less room for air spaces. Consequently, clay soils don’t hold nutrients and have poor drainage. Silty Soil contains a high proportion of particles and feels smooth to the touch. This soil is a soil because of the size of the particles allowing space for water to permeate. Nutrients are held by this dirt more easily than clay soil as a result of spaces. It’s easy to cultivate but may be compacted quite easily.
Sandy soil comprises a high proportion of sand particles and feels gritty to the touch, Allows for a lot of space in between particles and as a result is very free draining. This has its drawbacks 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 equally by the proportions of sand, silt and clay particles. It’s well drained but does not 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 structure. For a soil to be fertile it must have a pH value at a level and nutrients. Are the nutrients nitrogen and phosphorous for total health.
