Organic mulches in the vegetable cultivation (a Review)

Soil mulching is very important practice in field production. Different mulching materials can be use for different agricultural and horticultural species in different climatic environments. The main role of organic mulches is to protect the soil surface from the influence on unfavorable factors and to improve the growing conditions for the crop plants. Mulching reduces unproductive evaporation from the soil surface. Organic mulch also reduces soil wind and water erosion by protection the soil surface and reduces nutrient loss by runoff and leaching. Mulches conserve soil moisture, help maintain stable soil temperature, increase soil porosity and suppress weed growth. The main advantages of organic mulches are organic matter and nutrient supply not only for plants but also for soil organism. Mulch improves physical, chemical and biological properties of soil and ultimately enhances the growth and yield of crops. The purpose of this review is to comparative analysis of the scientific research on the benefits and drawbacks of mulches used in vegetable cultivation.
