"I wonder if you could you give me a hand providing me with some info.
regarding the above subject. A peruvian onion and garlic grower asked me
about the use of plastic covers to reduce the growing of weeds in his field.
Could you send me the technical characteristics of this plastic covers?.
Technical characteristics such as: type of plastic material (poliethilene or
polipropilene, other), thikness of the plastic layer, etc. My E-mail ID:
