The Sheep Promotion, Research, and Information Act of 1994 authorized the creation of the American Lamb Board as a commodity checkoff program. [2]Because individual producers of nearly homogeneous agricultural commodities cannot easily convince consumers to choose one egg or orange or a single cut of beef over another, they often have joined together in commodity promotion programs to use ...
Cutoff period is a term in finance. In capital budgeting , it is the period (usually in years) below which a project's payback period must fall in order to accept the project. Generally it is the time period in which a project gives its investment back if a project fails to do so the project will be rejected.
The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system.
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...
Such management practices that succeed in retaining suitable soil cover in areas under fallow will ultimately reduce soil loss. In a recent study that lasted a decade, it was found that a common winter cover crop after potato harvest such as fall rye can reduce soil run-off by as much as 43%, and this is typically the most nutritional soil.
According to the EPA, agricultural soil management practices can lead to production and emission of nitrous oxide (N 2 O), a major greenhouse gas and air pollutant. Activities that can contribute to N 2 O emissions include fertilizer usage, irrigation and tillage. The management of soils accounts for over half of the emissions from the ...
A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.
Good management of field residues can increase efficiency of irrigation and control of erosion. The residue can be ploughed directly into the ground, or burned first. In contrast, no-till, strip-till or reduced-till agriculture practices are carried out to maximize crop residue cover. Simple line-transect measurements can be used to estimate ...
