The relative sustainability of alternative, conventional and reduced-till farming system
Article Abstract:
The alternative farming system in an agro-climatic area is more sustainable as revealed by two studies in northeastern South Dakota in 1985. The studies analyze the sustainability of various alternative (organic), conventional and reduced-till farming systems taking into consideration various factors, such as soil erosion, pollution potential and others. Alfalfa hay was found to be most productive agronomically and economically in the alternative system in Study I which emphasized row crops.In the Study II, Green manure crop (clover) had the lowest agronomic production but performed well economically, like the conventional system.

Feedlot manure nutrient loadings on South Dakota farmland
Article Abstract:
The production and disposition of livestock manure from 78 feedlot farms in South Dakota are studied. Results show that manure production reached an average of 5,730 tons annually with 77% and 23% spread on cropland and rangeland, respectively. It is also found that manure applications by feedlot operators exceed crop and grass fertility requirements which may increase the threat of non-point-source water resources pollution.

Growth of corn roots under low-input and conventional farming system
Article Abstract:
A study was conducted to characterize the growth of corn roots on conventional and low-input farming systems. Conventional farming systems use synthetic fertilizers and pesticides, while in low-input farming systems, biological produced fertilizers are applied. An examination of the corn roots show that low-input farming systems produce long root length density compared to conventional farming systems.
