New farming techniques help farmers reduce waste. They also help farmers get the most crops out of their harvest each year.

The Conservation of Matter and the Conservation of Momentum are the consequence of the Conservation of Energy.
There are many different conservation programs throughout the world. They include the Farm Bill Conservation Program, the Conservation Stewardship Program, Conservation International, The Sierra Club, and the Wildlife Conservation Society.
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
Conservation of momentum means the sum of Momentum is constant. Conservation of Momentum is the result of Conservation of Energy.
The conservation of Energy-Matter.

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.

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.

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
