A three-state study found that seeding a cover crop of 1 bushel per acre of oats or other easily killed small-grain cover crop in the soybean field near the date of soybean planting can reduce excess water and take up some excess soil N (Figures 8a and 8b, Page 9). One of the most striking land-use trends in the central U.S. since the Second World War is the simplification of cropping systems toward dominance by corn and soybean [24, 25]. For example. Adequate soil fertility is a must for good corn production. Fertility re-quirements depend on yield goals, soil fertility levels, and cropping systems. Balanced fertility management is necessary to produce corn for more profit. Corn yields are often limited by low soil pH and nutrient deficiencies or tox-icities. cropping systems have been measured simultaneously in only a few earlier than corn. Soybean residues were hand-spread uni- formly over the plots after harvest. Cultural operations for Crop year F SB 12 3 4 F SB 12 3 4 mrn Wha Continuous corn 0 1 0 65 39 0 0 0

Sustainable Weed Management, available on request. Fortunately, a good crop rotation along with proper fertility management appears to suppress most soybean pest problems in organic produc-tion. Where nematodes have become a problem, rotating to non-host crops and integrating nemati-cidal cover crops into the crop mix have proved effective.   NRCCA Soil Fertility & Nutrient Management – Study Guide – 10/26/ 5 o Texture is defined as the proportion of sand, silt and clay in the soil. As the clay content increases, so does the CEC, resulting in a greater ability to hold nutrients. Combining the data from all three locations for all years (29 environments), first-yr corn and corn in the corn-soybean rotation yielded significantly more than the other cropping sequences (Fig. 1). There was a 15% increase in first-yr corn yield compared to continuous corn. Cropping systems enable the management of crops to efficiently use the available climatic and soil resources. Cropping systems vary in their biodiversity Biodiversity refers to all the species of living organisms in an agroecosystem Richness: number of species Evenness: distribution or relative abundance of the individuals of a species.

distinguish fields growing continuous corn (for at least three years) from those in a corn-soybean rotation5. Restricting the analysis to these two major cropping systems resulted in 1, usable observations (i.e., fields) of which were in continuous corn and were in a corn-soybean rotation. the SMAF was used to evaluate long-term cropping system studies at eight locations in the Great Plains (Wienhold et al., ). They found that reducing tillage and the incidence of fallow combined with more diversified crop rotations improved soil function (i.e., . ing pod fill, particularly after the R-3 growth stage. Recent research in Kansas has shown that in fields with an already high yield potential (greater than 60 bushels per acre), an application of 20 to 40 pounds of nitrogen per acre at the R-3 stage can increase yield by 5 to 10 percent.
