Plastic Mulch Benefits - Mulch India

Weed management
Plastic mulches prevent sunlight from reaching the soil which can inhibit most annual and perennial weeds.
Clear plastics do not prevent weed growth. Holes in the mulch for plants tend to be the only pathway for weeds to grow.

Black Plastic Mulch - Mulch India

Black plastic mulch is the predominant color used in vegetable production. It absorbs most ultra-violet (UV), visible, and infrared wavelengths (IR) of incoming solar radiation and re-radiates absorbed energy. Because thermal conductivity of the soil is high relative to that of air, much of the energy absorbed by black plastic can be transferred to the soil by conduction if the plastic mulch is in close contact with the soil surface. Heat transfer may or may not be desirable depending on the crop grown, time of year, and local climate.

Plastic Mulching - Mulch India

1. It is completely impermeable to water.

2. It prevents the direct evaporation of moisture from the soil and thus limits the water losses and conserves moisture.

3. By evaporation suppression, it prevents the rise of water containing salts.

4. Mulch can facilitate fertilizer placement and reduce the loss of plant nutrient through leaching.

Plastic Mulch - Mulch India

Plastic mulch can also help manage water. Since the plastic will prevent rainwater from penetrating the soil, you should plan to put irrigation under the black plastic. You can use either a soaker hose or drip-irrigation tape, which has emitter holes along its length and functions similarly to a soaker hose. The plastic mulch will prevent water loss through evaporation and may reduce irrigation needs by around 50 percent. The mulch also prevents waterlogged soils from heavy rainfall. With plastic mulch, you can achieve consistent soil moisture, which is loved by most vegetables.

White on Black Plastic Mulch -- Mulch India

What is white plastic mulch?
White on Black Plastic Mulch is primarily used for a "cooling" effect. The white surface is laid up to reflect heat away while the black surface is laid down to prevent weed growth. Great for lettuce, cauliflower, and broccoli.
