NATIONAL SEMINAR ON FERTIGATION held on 15th Sept 2017 at Vadodara, Gujarat

Plastics Mulching

Mulching is covering the soil around the plant with plastics film, straw, grass, hay, dry leaves, stones etc which prevents the loss of moisture and acts as a barrier between the soil and atmosphere. It helps in moderating the soil temperature & micro-climate in the plant root zone, which helps to increase yield and early maturity of crops.

There are coloured plastics mulch films, which determine its energyradiating behavior and also influences the micro climate around the plant.


Advantages
  • Provides favourable soi l moisture for development of roots and plants.
  • Prevents weed growth.
  • Provides ideal environment for earthworms and other soil micro-organisms beneficial for crops.
  • Improves soil micro climate.
  • Conserves water.
  • Effective in dry land farming.
  • Increases crop yield & keeps the crop clean.
  • Improves quality of produce.
  • Prevents soil erosion & run off.
  • Reduces soil compaction due to heavy rains.
