Differences in The Equipment Used
No-till planters have a disk opener (commonly referred to as a no-till coulter) that is located in front of the planting unit. This coulter is designed to cut through crop residue and into the hard crust of the soil. After the coulter has broken through the residue and crust, the disk opener of the planting unit slices the soil and the seed is dropped into the furrow that has been created and then a press wheel closes the furrow. The pictures are of no-till drills and they use the same principles as discussed above to plant the season’s crops.
With strip-tillage systems more precision is needed. The farmer will work the ground with a specialized implement to till up an eight to ten inch row and at the same time incorporate the fertilizer or chemical that the farmer so chooses. If the applicator’s chemical or fertilizer meter is off slightly, the farmer will not be applying an accurate rate of the chemical. This could result in increased expenses or reduction of the efficacy of the fertilizer program.

Famous quotes containing the words differences and/or equipment:
“The country is fed up with children and their problems. For the first time in history, the differences in outlook between people raising children and those who are not are beginning to assume some political significance. This difference is already a part of the conflicts in local school politics. It may spread to other levels of government. Society has less time for the concerns of those who raise the young or try to teach them.”
—Joseph Featherstone (20th century)
“Pop artists deal with the lowly trivia of possessions and equipment that the present generation is lugging along with it on its safari into the future.”
—J.G. (James Graham)
