Which method of soil conservation relies on minimizing the use of plowing?

conservation tillage


How does conservation soil and tillage help soil?

With conventional tillage (complete turning over of the soil), the bare soil is exposed to the erosive action of water, which, in many areas is the major route of soil loss. Under conservation tillage, the crop residue buffers the raindrops' energy, so water has less erosive force when it reaches the soil. This protection by residue, along with the rougher surface provided by the residue facilitates infiltration and decreases runoff -- runoff that carries soil and nutrients with it. In addition, macropores, which are the major route for water movement through soil, get disrupted in the surface 15-20 cm of soil by conventional tillage, but remain intact under conservation tillage. Improved macropore development also enhances water infiltration and decreases water runoff. Conservation tillage thus can also conserve water and fertilizers. http://people.oregonstate.edu/~muirp/constill.htm


How did summer fallow damage the soil?

If the summer fallow practice left the soil bare of any plant materials or residue, the soil was left exposed to potential erosion. Modern conservation tillage practices have greatly reduced this possibility.


How is the fertility of soil renewed and conserved?

Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility.


How would you describe the practice of summer fallow and how did this practice damage the soil?

Summer fallow is cropland that is purposely kept out of production during a regular growing season. If the summer fallow practice left the soil bare of any plant materials or residue, the soil was left exposed to potential erosion. Modern conservation tillage practices have greatly reduced this possibility. See the related link below.

What advantages does conservation tillage offer?

Conservation tillage systems leave at least 30 percent crop residue after planting and minimize water runoff and soil. The practices can stave soil erosion by as much as 90 percent.
