What does the mulch-till system of conservation tillage entail?
The mulch-till system disturbs the soil prior to planting and accomplishes weed control with herbicides and/or cultivation.
How does the ridge-till system of conservation tillage differ from the no-till system?
weeds may be controlled with herbicides and/or cultivation and the ridges are rebuilt during cultivation.
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.
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.
What is meant by conservation of energy in a closed system?
Closed system means that no energy enters or leaves the system; conservation means that in this case, the total amount of energy will not increase, nor decrease.
Where do you apply conservation of momentum?
Conservation of moment could be applied to any system if no external force acts on it.
Is the system in the law conservation of mass lab is an closed or open system?
closed
What is always true according to the law of conservation?
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.
What is an example of conservation of mass in a closed system?
the earth
What is the conservation energy?
Perhaps you mean "energy conservation", or equivalently, "conservation of energy". That refers to the fact that there is a quantity called energy, which can't be increased or decreased (in a closed system).
What is law conservation of massmatter?
Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
