Farmer dilemma

Of course it is required! Isn't that what farmers do!?! It turns out that the answer to that question isn't easy. Yes, many farmers turn, or till, the soil. But increasing percentages of farmers are opting not to till some or all of their fields, for a variety of reasons.

As farmers prepare to plant new crops this spring, they must weigh the pros and cons of till and no-till farming. On the one hand, tilling a field in preparation for planting aerates and warms the soil, and also buries weeds, animal waste, and leftover crops. However, once the soil is turned, it is much more vulnerable to erosion from wind and water and is likely to have increased run-off of soil and chemicals into local waterways.

On the other hand, leaving a field untilled allows leftover crops to act as mulch and helps protect the soil from erosion and run-off. However, planting seeds through this layer of mulch is more difficult and requires expensive machinery.

This method also may require more herbicide to control weeds, and, in some places, crop yields may be lower because the mulch keeps the soil cooler and seeds germinate later in the season. Can you Dig It?
