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.

What is the difference between covention tillage and conservation tillage?
Conventional tillage involves intensive soil disturbance through plowing, while conservation tillage aims to minimize soil disturbance and maintain soil structure. Conservation tillage practices, such as no-till or reduced tillage, help to reduce erosion, conserve soil moisture, and improve soil health compared to conventional tillage methods.
Which method of soil conservation relies on minimizing the use of plowing?
Conservation tillage is the method of soil conservation that relies on minimizing the use of plowing. It involves leaving crop residues on the soil surface to reduce erosion, improve soil health, and enhance water retention. By reducing the intensity of tillage, conservation tillage helps to maintain soil structure and organic matter content in the soil.
What farming methods help conserves soil?
Conservation tillage, crop rotation, cover cropping, contour farming, and terracing are farming methods that help conserve soil. These practices help reduce erosion, improve soil health, and minimize the use of conventional tillage methods that can lead to soil degradation.
How do conservation tillage practice slead to agricultural sustainability?
Conservation tillage practices lead to agricultural sustainability by reducing soil erosion, improving soil health, and enhancing water conservation. By disturbing the soil less, conservation tillage helps to maintain soil structure and biodiversity, leading to higher crop productivity and reduced reliance on external inputs like fertilizers and pesticides. Overall, these practices contribute to long-term sustainability by promoting more efficient and environmentally friendly farming systems.
What are the methods of soil conservation to prevent wind from eroding the topsoil?
Some methods of soil conservation to prevent wind erosion include planting windbreaks such as trees or shrubs, using cover crops to protect the soil, practicing reduced tillage or conservation tillage techniques, and implementing contour plowing to reduce the impact of wind on soil.

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.
What farming methods help conserves soil?
Conservation tillage, crop rotation, cover cropping, contour farming, and terracing are farming methods that help conserve soil. These practices help reduce erosion, improve soil health, and minimize the use of conventional tillage methods that can lead to soil degradation.

What is the type of plowing that harms soil as little as possible?
Conservation plowing is a type of tillage that aims to disturb the soil as little as possible in order to minimize erosion and maintain soil structure and fertility. It can include techniques such as no-till or minimum tillage practices.
What type of plowing disturbs soil as little as possible?
Conservation tillage methods, such as no-till or minimum tillage, disturb the soil as little as possible. These methods involve minimal disturbance of the soil structure, allowing for improved water infiltration and reduced erosion while maintaining soil health.
