	Bacterial Wilt of Cucurbits
		Some growers plant "catch crops" of cucurbits thickly over a small area a few days before they plant the main crop.
		Catch crops are meant to attract beetles which can be sprayed with insecticide.
		Unfortunately, catch crops may increase beetle populations, if not sprayed properly.

	On-Farm Research into Reducing Nutrient Loss in the Maritimes (Site not responding. Last check: 2007-11-04)
		Catch crops are cover crops planted after cash crops are harvested or after legume ploughdowns.
		The catch crops take up and hold the nutrients in their tissues, preventing leaching from the soil.
		To be a useful catch crop, plants must be fast growing, highly competitive against weeds, and be able to quickly take up substantial amounts of nitrogen.

	Cover Crops and Green Manures
		A catch crop is a cover crop established after harvesting the main crop and is used primarily to reduce nutrient leaching from the soil profile.
		The contribution of organic matter to the soil from a green manure crop is comparable to the addition of 9 to 13 tons per acre of farmyard manure or 1.8 to 2.2 tons dry matter per acre (2).
		By having the cover crop in place early in the growing season, the population of beneficials is much higher sooner in the growing season than would be the case if only the main crop were serving as habitat for the beneficials.

		The total S uptake in aboveground biomass in barley following incorporation of catch crops or application of inorganic S was used to estimate the relative mineralisation of catch crop S available for barley during one growth season (figure 2).
		When deciding on a strategy for catch crops the farmer must prioritise between optimisation of N effects, control of soil borne diseases, improvement of soil structure, erosion control, minimising the cost of growing a catch crop, or import of N through fixation by legumes.
		Such catch crops may be incorporated in late winter or early spring - late enough to avoid leaching from mineralisation of catch crop residues and early enough to avoid the catch crop from taking up nutrients that would normally be directly available for the succeeding crop.

	Organic Eprints - 3173: Plant-availability of catch crop S following spring incorporation
		Catch crops might reduce sulphate leaching and thereby increase the overall S use efficiency in crop rotations.
		The catch crops showed huge differences in their ability to sequester S. The best catch crops (legumes on sandy loam), sequestered 10-12 kg S ha-1 and the poorest catch crops (ryegrass and sorrel on coarse sand), sequestered less than 3 kg S ha-1.
		In the case of legume catch crops it is advisable to use a supplemental S source.

	Green Manures (Site not responding. Last check: 2007-11-04)
		Crop rotations are designed so that the green manure crops are grown in between cash crops, thus still gaining soil-conserving benefits without detracting from the cash crops.
		A catch crop has a brief period of growth and is either worked in after the main crop has been taken off or planted between two main crops.
		Applications of compost or liquid manure are made to catch crops which soak up a lot of nutrients and immobilize them in their tissues.

	Succession planting - Wikipedia, the free encyclopedia
		Two or more crops in succession: After one crop is harvested, another is planted in the same space.
		For example, a cool season spring crop could be followed by a heat-loving summer crop.
		A catch crop refers to a specific type of succession planting, where a fast-growing crop is grown simultaneously with, or between successive plantings of, a main crop.

		The effects of crop rotations and catch crops are presented in Table 2.
		There were no significant differences in nitrate leaching between crop rotations at the three locations except for the interaction between crop rotation and catch crop at Foulum, where the nitrate leaching in the treatment without catch crops was 42% larger in rotation 2 than in rotation 4.
		Here, the catch crops did not reduce the nitrate concentrations immediate after harvest, but after one to two months the concentrations were effectively reduced in the treatments with catch crops relative to the treatments without (Figure 1).

		The anglers' catch and standing crop of trout were estimated in order to evaluate the effects of the improvement structures.
		The yearly parameters of catch and standing crop in Section A were related to those in Section B through a ratio of A to B. The experimental design called for a comparison of the parameters for the 5 years before stream improvement, 1949-53, with the 5 years during stream improvement, 1954-58, i.
		The increase in brook trout as recorded in catch-and standing crop must be attributed either to better survival or to migration of trout in response to the addition of cover.

	Sustainable Production Techniques - Cover Crops
		as a 'catch' crop for nutrients, planted after harvest of the main crop or between the rows of the cash crop to reduce leaching of nutrients.
		For a catch crop to intercept and recycle nutrients, pick a crop efficient at scavenging a particular nutrient or able to grow when residual N is still present in the field.
		As discussed in greater detail in Soil Management, the actual contribution of the cover crop to soil organic matter will depend on many factors, including the amount of growth of the cover crop and whether the crop is removed from the field as hay, left on the surface, incorporated, or used as a living mulch.

	Nitrogen Leaching from Agricultural Land in Sweden (Site not responding. Last check: 2007-11-04)
		The aim of the calculations in this paper was i) to estimate the effect of measures to reduce nitrogen leaching from arable land and ii) to estimate what reduction in the gross load from southern Sweden could be expected.
		The largest reduction in leaching was obtained with the combination of catch crop, spring application of manure and reduced rate of fertilizer-N. Total gross load decreased with 16% in this scenario.
		The catch crop scenario reduced gross load by a mere 5% because it was only introduced in 30% of the acreage of spring cereals.

		Ramamurthy said that during a CICR survey among the summer cotton tracts in the state, a special type of growing summer cotton as a ‘catch crop’ in the banana fields was noticed in and around Tiruchirappalli tract.
		Farmers, after cultivating one or two ratoon crops of ‘Nendran’ banana, start cultivating cotton as catch crop in the fields and cotton seeds were dibbled in february in between the banana rows, Ramamurthy said.
		As most of these catch crop cotton farmers were tenants, this practice was discovered by the tenant-farmers, in order to extract the soil nutrients and utilise the land to the maximum at the limited time, CICR scientist pointed out.

	Rye as a Cover Crop
		In the course of my research on cover crops in North Carolina and Virginia, I drilled rye at 90 pounds of seed per acre at 1 to 1½ inches deep and had excellent stands.
		When it follows corn and other crops fertilized with nitrogen, however, it seldom requires additional N. Rye has a good reputation for scavenging residual soil nitrogen when it follows other crops, and it is commonly grown for this purpose.
		When the rye cover crop is incorporated into the soil, the field can be easily cultivated but the weed suppression provided by the rye will be largely gone.

	Growing sesame as alternative, rotation, catch, failed out crop
		Sesame (Sesamum indicum L. Pedaliaceae) is one of the oldest crops known to humans.
		Sesame has proven to be an excellent alternative crop and a catch crop for failed out crops, e.g., hail destruction of cotton or freeze or insect damage to wheat.
		By using sesame as a rotation, the soils are improved, and the sesame provides integrated crop management by suppressing cotton root rot and root knot nematodes.

	Reducing Ag Nitrate Pollution
		Through chemical analysis of the soil to determine natural nitrogen release, and by accounting for contributions from supplementary manure and legume crops in rotation, farmers can better estimate the amount of additional nitrogen fertilizer required to obtain the desired yield of a crop.
		A cover crop is a planting of (typically) grass and/or forage legumes on a field in-between production seasons.
		Another concept of cover cropping is the use of “catch crops.” A catch crop is a non-leguminous cover crop, overseeded or planted shortly after main crop harvest.

		While mechanical weed control can be carried out in systems without catch crops, it is not possible to do so in systems with catch crops without affecting the establishment of the catch crop.
		Since the results are only from the two first years of the experiments, it is not possible to conclude anything about the crop rotations as such.
		There are however differences related to the other experimental treatments in the experiment: the presence or absence of catch crops and manure.
