Well, I don't know if you know about this, but in California, there's a huge amount of plastic that's used in fields right now as plastic mulch, and this is plastic that's making these tiny little greenhouses right along the surface of the soil, and this provides warming the soil to increase the growing season, it allows us to control weeds, and, of course, it makes the watering much more efficient.
Jeg ved ikke om i kender til det her men i Californien, er der en enorm mængde plastik der bruges på marker til at holde fugten i jorden, det bruges til at lave små drivhuse, langs jordoverfladen, og dette sørger for at varme jorden op, og forlænger gro-sæsonen det skaber større kontrol med ukrudt, og det gør vandingen meget mere effektiv.
