leaving the soil undisturbed from harvest to planting except for nutrient injection and controlling weeds primarily with herbicides
The mulch-till system disturbs the soil prior to planting and accomplishes weed control with herbicides and/or cultivation.
weeds may be controlled with herbicides and/or cultivation and the ridges are rebuilt during cultivation.
system of planting crops on ridge tops in order to reduce farm production cost & promote greatern soil conservation.
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.
Conservation laws suggest that energy, matter, and momentum cannot be created or destroyed but can only change forms or be transferred between objects. Conservation of energy states that the total energy in a closed system remains constant. Conservation of matter indicates that the total mass in a closed system is constant. Conservation of momentum asserts that the total momentum of an isolated system remains constant in the absence of external forces.
The conservation of angular momentum in a system can be ensured by making sure that no external torques act on the system. This means that the total angular momentum of the system will remain constant as long as there are no external forces causing it to change.

The conservation of matter applies in closed systems, where no matter can enter or leave. In open systems, matter can be exchanged with the surroundings, so the conservation of matter may not be strictly true.
There is no one "law of conservation", there are several laws, such as conservation of energy, conservation of mass, conservation of electric charge, conservation of rotational momentum, etc.What is always true is that there is SOME quantity that doesn't change in the case of a closed system.
