But what does mulching consist of? Mulching consists of creating soil protection all around the plants that are intended to be grown, in order to prevent harmful subtraction of moisture from the soil. Furthermore, the practice of mulching prevents the proliferation of weeds and their attack on plants and vegetables. This function is of particular importance since weeds and weeds, in case of penetration into the soil, would compete with the vegetables by taking away the precious nourishment they need to live and grow in the best way. Furthermore, in the event of heavy rains, mulching prevents the washing away of the nutrients contained in the soil - in particular, of mineral salts such as nitric nitrogen.
In addition, it is very useful in some cases to carry out mulching using roofing materials of organic origin, so that during the cultivation period this organic substance slowly releases the nutrients that assist the vegetables throughout the vegetative cycle.
When not using a synthetic material, it is good to use organic material such as straw, dry leaves, leftover grass clippings, compost and the like; everything will be laid on the ground forming a layer at least twenty centimeters high so that it can carry out its mandate with profit. In some cases it is possible to mulch with plastic materials such as polyethylene or non-woven sheets, both strictly black. Sometimes, when available, it is possible to replace plastic sheets with black corn sheets, biodegradable in the earth.
PACCIAMATURA AND SUMMER
In addition to carrying out a contrasting action against the proliferation of weeds, as we have said, mulching serves a great deal to maintain a degree of freshness and humidity in the surface and substrate of the cultivation soil, avoiding that during the hot season - especially if arid and dry - it dries excessively losing the humidity accumulated during the winter season. When types of plants are cultivated that require a high degree of humidity, or in any case not excessively low, mulching is the ideal solution to avoid dangerous humidity dispersions.
