4 Types of Mulching You Should Know

Types of mulches: Materials used for mulches are crop residues levees clippings, bark manure, paper, plastic films, etc.

1. Plastic films: Plastic fnms are more widely used as mulch. They help in maintaining higher water content in soil resulted from reduced evaporation, induced infiltration, reduced transpiration from weeds or combination of all these factors. They are relatively expensive expensive .

2. Crop residues or stubble mulch: - Crop residues and other plant waste products (Straw, cloves, leaves, corn, and sawdust) are widely used as mulch. These materials are cheap and often readily available. The permit water to enter in the soil easily, when maintain at adequate level. These materials result in  increased water content and reduced evaporation. Amongst the mulches tried light and thin stem material like dry grass was most effective as it provide good canopy, followed by gram stalks and wheat. Jawar stubbles were not as effective as other because of it is heavy weight and less canopy (cover). The mulch should be applied immediately after crop emergence to get optimum advantage. When these mulches are used the other crop operations like interculturing are not physible hence saving in cost of cultivation.

Vertical mulch: - Rainfall in dry farming area is with high intensity; due to moderately slow rate of infiltration the runoff is heavy. The water thus running as runoff could be stored in profile itself. In the recent past new technique has been evolved to tap such water.
Vertical mulch is a technique which consists of digging suitable trenches across the slope and thus making more surface are a available for water absorption. The open treaches are likely get silted in short period. This however can be prevented by inserting organic form waste material like straw stubbles or stalks which is called filter. The filter should be resistant to decomposition.

4. Soil or Dust mulch: If the surface of the soil is loosened, it acts as mulch for reducing evaporation. This loose surface of soil is called soil mulch or dust mulch. Interculturing creates soil mulch in growing crops and helps in closing deep cracks in vertisols.
