Soil Solarization Process

In summer, when the straight sunshine and the temperature is high (25 April to 15 May), then the time of soil solarization is the best.
First, wet the soil with water, or saturate it with water.
These beds are covered with a transparent 200 gauge (50 μm) polyethylene sheet and spread for 5-6 weeks in the summer, and the edges around it are pressed well with soil so that air cannot enter.
In this process, the temperature of the soil under the polythene sheet increases by 8–100C than normal. Due to which harmful insects present in the bed, spores of diseases and seeds of some weeds are destroyed.
The polyethylene sheet should be removed after 5-6 weeks.
This method is very beneficial and less expensive for the nursery and it destroys different types of weed seeds/ rhizomes (except some like Cyperus rotundus and Convolvulus arvensis etc.).
Parasitic weeds Orobanche, nematodes, and bacteria from soil diseases, etc. are also destroyed. This method is very practical and successful.
In this way, the soil can be treated without adding anything to the soil.
