Mulching is the process or practice of covering the soil/ground to make more favourable conditions of root zone for plant growth, development and efficient crop production. The various types of plastic mulches are available in market and its selection depends upon the very purpose of mulch. The plastic mulch affects below the soil microclimate, above the soil microclimate, weeds growth, soil moisture, insect behavior etc. The soil temperature plays a very important role in crop productivity and the plastic mulch can be used to enhance or decrease the soil temperature as per requirements. Research continues on field evaluation of new formulations of degradable, wavelength-selective, and coloured plastic mulches.
