Plastic Mulch Promised Better Harvests. It May Be Hurting The Soil Instead.

"The invisible pollution may linger for centuries." 

"When someone asks farmer Naiku Gaikwad about soil pollution in his village, he points to an abandoned 40-foot well filled with plastic.

“After harvesting their crops, farmers here toss hundreds of kilograms of plastic mulch into this well,” said the 69-year-old farmer from Jambhali village in Maharashtra, India.  

Farmers started using plastic mulch in this village two decades ago because it provided short-term benefits like earlier harvests, increased water-use efficiency, higher yields, and reduced labor costs.

The mulch is a thin, flexible sheet, usually black- or silver-colored, that farmers spread over the soil like a blanket to suppress weeds, retain moisture, and regulate soil temperature."
