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.

Which method of soil conservation relies on minimizing the use of plowing?
conservation tillage
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 did the crop rotation system increase crop yields?
Crop rotations increase crop yields by improving soil conditions and reducing weed and insect populations. Rotations also help producers use conservation tillage successfully. A well- planned crop-rotation system can help producers avoid many of the problems associated with conservation tillage, such as increased soil compaction, perennial weeds, plant diseases, and slow early season growth.
Different types of soil conservation?
Soil conservation are ways to make sure that the soil stays clean and not contaminated. Some different types of soil conservation are different farming techniques, conservation tillage, contour bonding, and bench terracing.
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.
Which method of soil conservation relies on minimizing the use of plowing?
conservation tillage
What are Two types of soil?
Conservation Tillage and Wind breaks
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.
How conservation of dam help in soil conservation?

What is tillage operation?
system of planting crops on ridge tops in order to reduce farm production cost & promote greatern soil conservation.
What is a cropping plan?
A Cropping System is a general term that describes how a producer might grow a crop. A basic distinction is between conventional tillage & conservation tillage. Conservation tillage systems are methods of soil tillage which leave a minimum of 30% of crop residue on the soils surface with small grain residue during the critical soil erosion period. This slows water movement, which reduces the amount of soil erosion & benefits farmers through significant savings in fuel & labor. Conventional tillage refers to tillage operations considered standard for a specific location of crop & tend to bury the crop residues; usually considered as a base for determining the cost effectiveness of erosion control practices.
What does the no-till system of conservation tillage entail?
leaving the soil undisturbed from harvest to planting except for nutrient injection and controlling weeds primarily with herbicides
