Mulch is defined as a layer put to the surface of a farm for reasons like weed control, soil water conservation and boost soil fertility. The following are some benefits of mulch.
Obviously, many farmers opt for mulch to conserve the soil moisture and allow normal growth of plant despite the harsh weather condition. The mulch conserve the soil moisture by controlling the temperature of the soil and trap the moisture. Food security is usually guaranteed in a country whose farmer use techniques like mulching to grow food during the dry season. Organic mulch like the alfalfa mulch traps the moist that tries to escape into atmosphere and return it back to the soil.
Secondly, mulch is used to prevent erosion of top fertile soil. Agents of erosion carry away loose top fertile soil leaving behind infertile hard soil. When soil erosion of the top fertile soil takes place, the fertility of the farm is greatly reduced and this makes farmers incur a lot of losses. Soil barrenness can cause a farm to be unproductive leading to famine and hunger. Strong winds are also effective soil erosion agent. The hard pan is left behind after erosion makes tilling a farm so difficult.
The third benefit of using mulch in your farm is that the fertility of the soil is increased. When organic mulch decompose in the soil, the fertility is boosted. This helps to reduce the amount of inorganic chemical fertilizer used on a farm which is quite expensive while mulch is very cheap. When mulch decomposes into manure, the soil acidity is improved which translates to the proper growth of crops in a farm.
Weed control is another benefit of using mulch in your farm. Mulch suppress the growth of weed by cutting the supply of necessities for seed germination. Germination of a seed is facilitated by air, water, warmth, and minerals. The supply of air is reduced by a great percentage leading to failure of weed seed to germinate and instead decompose and become manure which boosts the soil fertility.
The affordability of mulch is another advantage of using mulch in your farm. Mulch does not require specialized skills to prepare. Companies that sell mulch have favorable prices and they deliver the mulch to the farm of a customer.
The sixth benefit of using mulch is that they can be used for decoration purposes and authentic purposes. River stones that are used to mulch city trees are very monumental and appealing to the eyes. Properties of river stones like color make them ideal decorative mulch.
Lastly, mulch is environmentally friendly because they decompose very fast as oppose to other methods of farming like the use of fertilizes. When mulch decompose and become manure, the water retention rate of the soil is improved.
