*7.2.1 Conservation of soil moisture*

Several abiotic variables could be responsible for the loss of moisture from the soil. These variables include high winds, elevated temperatures, harsh climatic conditions, etc. Mulching helps to reduce weed infestation and water loss through evaporation. Straw mulch has been shown to minimize evaporation by up to 35%. However, mulching reduces direct soil water evaporation, making more water available for transpiration. This way of water conservation helps the plants to maintain water balance, especially in regions with little precipitation per annum. Also, mulching reduces erosion and nutrient loss by protecting the soil surface.
