What is mulch?

Have you ever noticed the light and soft surface coating on the soil? what is the Types of mulch? The light and soft surface coating on the soil is called mulch. This coating can be a layer of straw, plastic sheet, leaf soil, sawdust and many other materials. What is mulch and what is its use? The English word mulch is probably derived from the German word mulch. This coating protects the soil and roots of the planted plant from rain, damaging, frost, evaporation and erosion damage.

In this article, we want to understand why farmers need nylon mulch in agricultural work and why this is important after we are fully acquainted with soil cover. Now we draw your attention to the continuation of this article.

Types of mulch

There are different types of mulches. In fact, mulches are classified into two types, organic and inorganic. The choice of soil cover should be based on the needs of each crop or area.

Organic mulch

Organic mulch, also called natural or biological mulch, contains natural materials such as dry grass, straw, straw, bark, chopped wood, leaves, sawdust and compost.

Shrub bark is the most widely used type of mulch

Leaves of coniferous trees

Cut grass

Natural mulch or organic mulch must first be decomposed and then replaced, but in the process the soil structure and its natural content are also improved. The drier and woodier these mulches are, the slower they decompose and the less nutrients they deliver to the soil.

Adequate knowledge of mulch raw materials should be available as it can contain weed seeds or chemicals. Spreading mulch is not a good way to choose your items because it improves your work and contaminates your plants with chemicals. Each natural mulch has its own application.

Inorganic mulch:

Surfaces on inorganic or chemical soils are coatings made of plastic or polyethylene that spread over the soil. This product is used to prevent the growth of weeds and also the evaporation of water from the soil. Plants grow from the pores that form on the surface of the film. The thickness of these nylons is between 30 and 50 microns. Plastic mulch is produced in different colors and sizes for different needs.

The durability of mulches depends on their thickness. Most brittle plastics can be used on ships, but heavy winds can break them. Sturdy plastics survive after two cultures. The mulch film is placed in parallel lines on the surface of the prepared soils. The soil bed should be free of plant debris and secured with a heavy object to the edges of the soil.

Coatings should adhere tightly to the soil to transfer heat well and prevent it from being released and moved by the wind. The movement of mulch by the wind may tear the plastic and destroy its ability. Mulch layers can also be a barrier to the release of the toxic gas methyl bromide, which is used to kill soil bacteria. Mulch film allows farmers to use less methyl bromide.

Important points regarding the use of mulch

Farmers who use mulch on the farm should pay close attention to the following:

Use of suitable animal manures (dry and rotten fertilizers)

Adjust the irrigation circuit and use irrigation types with pressure adjustment

The use of fungicides to disinfect the soil (irregular irrigation and improper use of manure) will lead to an increase in parasitic fungi.

Advantages of using mulch

To explore the benefits of using mulch, we need to know that both natural (organic) mulch and inorganic mulch can be used positively; It’s up to you to decide which one is better. But the use of natural and chemical soil in agriculture is one of the most important products that every agriculture needs.

The benefits of using organic mulch include improving soil structure, improving soil moisture capacity and maintenance, protecting soil from erosion, adding nutrients and organic matter to soil, and controlling weeds. It should be noted that when using carbon-rich materials such as sawdust and chopped wood, sufficient nitrogen should be added to the soil.

  1. Using inorganic mulch to plant the plant earlier and increase economic efficiency in crop production
  2. 2. Maintaining soil moisture with the help of plastic mulch
  3. Prevent weed growth
  4. Reduction in the withdrawal of fertilizer nutrients from the plant root reach
  5. Improve product quality
