	Consequences (vol. 1, No. 1) - Past and Present Land Use and Land Cover in the USA
		Cropland is land in farms that is devoted to crop production; it is not to be confused with total farmland, a broad land- use or land-ownership category that can incorporate many forms of land cover.
		Changes in the area and the location of cropland, for example, are the result of the addition of new cropland from conversion of grassland, forest, and wetland and its subtraction either by abandonment of cropping and reversion to one of these less intensive use/cover forms or by conversion to developed land.
		Cropland abandonment in some areas of New England began to be significant in some areas by the middle of the nineteenth century.

	ERS/USDA Briefing Room - Land Use, Value, and Management: Major Uses of Land
		Together, harvested cropland, crop failure, and summer fallow accounted for 340 million acres of cropland used for crops in 2002, unchanged from 2001.
		The decrease in cropland used for crops reflects lower harvested acres of wheat and, to a lesser degree, sorghum, barley, oats, and cotton.
		Harvested cropland fluctuated from a low of 297 million acres in 1993 to a high of 321 million acres in 1997 and declined to 307 million acres in 2002.

	Cropland Losses Threaten World World Food Supplies \| Worldwatch Institute
		At least five percent of China's cropland was lost in only six years (1986- 1992), in part to urban expansion and industrialization.
		Irrigated land, just 16 percent of total cropland, supplies 40 percent of grain, so each hectare of irrigated land lost is of particular concern.
		If that is the case, continued tolerance of unjustified losses of cropland will increase the pressure on yields, and with it, the risk of supply failures.

	How much will feeding more and wealthier people encroach on forests? - Paul Waggoner and Jesse Ausubel
		Waggoner (1994)[9] and Goklany (1999)[9] calculated not cropland encroaching on forests as population grew, but the rising yields and intensities of cultivation that would shrink or stabilize cropland during the next 50 years.
		In 48 of 135 nations the sum of forest and cropland shrank, and in 15 it grew.
		If we symmetrically assume a reverse encroachment factor for reforestation of cropland of 1/3 to 1, the land spared from crops by 2050 might add potential for a round 100 M ha or twice the area of France, a 3% increase of the global 3,454 M ha of forest.

	Children's report card: Erosion of cropland
		The percentage of cropland estimated to be eroding above tolerance levels due to water declined from 14 percent to 9 percent between 1982 and 1997.
		For the nation, 13 percent of cropland was estimated to have unacceptable wind erosion, compared to 39 percent in Minnesota.
		In 1997, as in 1982, cultivated cropland was responsible for at least 96 percent of the total soil loss while making up less than 75 percent of the acres on which the loss was estimated.

	Soil Loss Overview
		Much of Canada's cropland has lost half of its organic matter, and fallow periods have dropped, so it is hard to imagine farmers putting up with all this with unused good cropland just sitting there.
		Cropland degradation rates tend to increase as pressures on cropland to produce are increased.
		Population pressures forcing croplands onto steeper slopes causing increased runoff and erosion debris to damage croplands down on the valley floor.

	Florida Agricultural Land Values Increase: 2000 Survey Results
		The value of nonirrigated cropland and improved pastureland are closely related across regions and were $2,212 and $2,195 per acre, respectively, in the Central region.
		The values of nonirrigated cropland and improved pastureland for the Northeast region were about 80 percent of those in the Central region and the value of these types of land in the South region were about three-fifths of those in the Central region.
		The estimated cash rent for nonirrigated cropland was $31.70 per acre in the Northwest region and $25.10 per acre in the Northeast region (Table 2).

	Fertilizing Cropland with Poultry Manure (Site not responding. Last check: 2007-10-30)
		If the manure produced on a farm cannot supply all of the farm's crop nutrient needs, it is best to base the manure application rates on the phosphorus requirements, resulting in a lower manure application rate and the need for supplemental fertilizer.
		Correct application of manure to cropland is critical to maximize the value of manure to crop producers.
		Composting poultry manure and its bedding or litter is often considered due to the nature of poultry manure (high C:N ratio and lower moisture content); and the need to export poultry manure because of limited crop acres.

	ORECCL-Oak Ridge Energy Crop County Level Database
		These latter three types of cropland are excluded because they will be more costly to convert to energy crop production and/or they have a different land rent value than conventional crops (orchards and vegetables are high value crops and unlikely to be converted to energy crop production).
		These are the 1993 state cash-rent values for cropland and pasture land as reported by the Economic Research Service (ERS) of USDA (ERS 1993); the average annual CRP payment ($/acre/yr) for all CRP-enrolled land in the county; and a derived county-level cropland cash-rent value.
		That is, if all cropland in the region were planted to the energy crop using good practices and the best stock, energy crop experts would expect 50% of the land to achieve at least the "median" yield.

	AGR-91 CROPLAND ROTATIONS FOR KENTUCKY
		Of Kentucky's 25 million acres of land, about 15 million acres are potentially suitable for agricultural cropland use, either for row crops, hay and meadow crops, or permanent pasture crops.
		On a statewide basis, erosion hazard is by far the greatest limitation for use of cropland with about 11.4 million acres (about 75% of the total cropland acreage) being subject to such risks.
		Cropland rotations are not new to Kentucky farmers.

	February 14, 200: Paving the Planet: Cars and Crops Competing for Land
		Until now, the paving over of cropland has occurred largely in industrial countries, home to four fifths of the world’s 520 million automobiles.
		More often than not, cropland is paved simply because the flat, well-drained soils that are well suited for farming are also ideal for building roads.
		Nearly all of the 3 billion people to be added to the current world population of 6 billion by mid-century will be born in developing countries where there is not enough land to feed everyone and to accommodate the automobile.

		As a result, they prefer cropland settings with nearby undisturbed areas such as roadside ditches, crop borders, abandoned cropland, and over-grazed pastures or rangeland.
		The twostriped grasshopper is the earliest hatching grasshopper of concern in cropland with eggs beginning to hatch from mid to late May. The eggs of the migratory grasshopper hatch about a week later, with those of the redlegged and differential grasshoppers hatching about three weeks after the twostriped.
		A longer term solution to reduce grasshopper potential is to reduce the attractiveness of abandoned or weedy areas to cropland grasshoppers by establishing a dense grass cover that includes few broadleaf plants.

		For example, average sheet and rill erosion rates on all cultivated cropland was reduced from 4.6 tons/acre/year in 1982 to 3.0 tons/acre/year in 1997.
		Estimated erosion rates on cultivated croplands that were enrolled in the CRP were dramatically reduced.
		These cultivated croplands, which were eroding at an average rate of 7.2 tons/acres/year in 1982, before they were enrolled in the CRP, were eroding at an average rate of.4 tons/acre/year in 1997, after establishment of permanent cover.

		In order to ease the task of developing a new design for each buffer application, we present a general width and vegetation design which we think can be used in most cropland situations with acceptable results.
		Trees and shrubs near the waterway stabilize the bank, improve and protect the aquatic environment, and protect cropland from flood erosion and debris damage.
		This design may provide only limited control of dissolved nutrients and pesticides in cropland runoff; and be ineffective for stabilizing serious streambank erosion.
