Many people back then thought that no till farming was a massive advancement for agriculture. This was the time when they needed a new soil preservation method that could solve fertile soil damaged by water and the wind at proportions figured in tons per acre per year.
To give you more idea about this technique, Exapta Solutions, Inc and other experts list the basics and benefits of no till farming:
The Basics of No Till
Conventional tillage plows the earth, which is usually a variety of moldboard, to a depth of eight to 12 inches. Farmers will then disk the plot for no less than twice to get the seedbed ready before they begin to plant something in it.
In no till farming, however, they don’t follow the first three phases of traditional cultivation. They plant directly in the remains of past weeds and plants using an equipment called a colter. It trims a slot for a few inches wide before they use another device to put the seed and close the trench.
The Benefits of No Till
The Plowman’s Folly book written by Edward H. Faulkner in 1943 mentioned that nobody has ever developed a scientific purpose for plowing. Nevertheless, 40 years after the said journal cracked the basics of agricultural science, the majority of farmers still plow. Why is this, exactly?
Probably the most apparent and commonly claimed purpose is that farmers till the soil to release oxygen. This is how water spreads to the area where roots grow and that loose soil will make it easier for roots to flourish and evenly spread. With the use of moldboard plow, however, this isn’t the case because it doesn’t essentially produce such soil.
What’s beneficial about no till farming is that it won’t lead to a soil with broken structure caused by disking and plowing. Untilled soil also begins to be less compacted compared to fields worked by heavy machines — and it stays that way for a long time. No wonder farmers decided to transition to this technique and continued to use it since then.
