Sustainable farming practices – No-till farming

The image above (Source) shows how no-till farms look like. See the dried up weeds/ plants between the rows.

The video starts on a no-till field — one that isn’t ever plowed. Instead of tilling, or turning over the soil to kill weeds, farmers plant directly into the thatch of grasses and usually use an application of herbicide to knock down weeds. When farmers leave fields bare, like in the other field, soil washes away and local waters are polluted.

Groundcover protects the soil and dramatically reduces erosion. People often think sustainable farming means no chemicals, but sometimes judicious use of chemistry allows for more environmentally friendly options — like keeping the ground covered.
