Plastic film harm to the environment

 

First, the soil structure damage. Usually in the agricultural production process when pieces of plastic sheeting after entering the field, which would change the structure of the soil, so that soil productivity decline, leading to reduction in crop yields, a direct impact on the harvest.

Second, some residual plastic film in the soil would not facilitate the exchange of soil moisture and gases, and plastic debris barrier will not conducive to normal growth and development of crops.

Third, after use will also affect the survival of microorganisms in the soil. Plastic film in the decomposition of the soil can be said to be a lengthy process, which itself will decompose volatile many harmful substances, thus arriving affect microbial viability.

Fourth, there is a most serious hazard is when harmful substances in plastic film residue decomposition process will produce thus contaminating groundwater, if not handled properly or even cause secondary pollution to the environment! We have to use environmentally friendly means to deal with, will minimize the harm.
