Mulching films

Hi-tech mulch films is use for process of convering soil around the plant roof area with a view to insulate the plant and its roots from the effect of extreme temperature fluctuation.

Grower use mulching to save water, product earlier, higher and healthier yields, and to product plant with a better commercial appearance Mulching has beneficial effects on soil, and on the environment. These include moisture retention, maintaining a proper structure, better use of fertilizers, protection of growing plants . less product damage and elimination of weeds when using opaque plastics.

All the plastics used for mulching increase soil temperature during the day , apart from the white and aluminized plastics which reflect light. Black plastics is best for preventing the growth of weeds. Inside greenhouse, white plastics is used as a reflective mulch to increase the quality of light available for the plants.
   
Advantages of Plastic Mulching
It is completely impermeable to water.
It prevents the direct evaporation of moisture foam the soil and thus limits the water losses and conserves.
By evaporation suppression, it prevents the rise of water containing salts.
Mulch can facilitate fertilizer placement and reduce the loss of plant nutrient through leaching
Mulches can also provide a barrier to soil pathogens
Opaque mulches prevent germination of annual weeds from receiving light
Reflective mulches will repel certain insects
Mulches maintain a warm temperature even during nighttime which enables seeds to germinate quickly and for young plant to rapidly establish a strong root growth system.
Synthetic mulched play a major role in soil solarisation process.
Mulches develop a microclimatic underside of the sheet, which is higher in carbondi-oxide to the higher level of microbial activity.
Under mulch, the soil structure is maintained during cropping period .
Early germination almost 2-3 day.
Better nodulation in crops like groundnut.
Less nematodes population.
Water erosion is completely averted since soil is completely covered foam bearing action of rain drops.
When compared to organic mulches, it serves for a longer period.
   
Moisture conservation
Plastic film with its moisture barrier properties does not allow the soil moisture to escape water that evaporates from the soil surface under mulch film, condenses on the lower surface of the film and falls back as droplets.
Thus moisture is preserved for several days and increases the period between two irrigations.
The irrigation water or rainfall either moves into the soil thru holes on the mulch around the plant area or through the un-mulched area.
   
Weed control
Black plastic film does not allow the sunlight to pass through on to the soil
Photosynthesis does not take place in the absence of sunlight below black film hence, it arrests weed growth
