Responses of Soil Water, Nitrogen, and Organic Matter to the Alfalfa Crop Rotation in Semiarid Loess Area of China

Jun Wang; Feng-Min Li; Yu Jia Journal of Sustainable Agriculture 2006. doi:10.1300/j064v28n01_10

Other claims from this paper (15)

Intervention effect Millet fields converted from alfalfa grassland had higher soil moisture than alfalfa grassland over two years.
Intervention effect Planting millet was not helpful for soil water restoration in the first year.
Intervention effect planting potatoes changed soil water by 36.0 mm in the second year after alfalfa conversion.
Intervention effect spring wheat changed soil water by 11.3 mm in the second year after alfalfa conversion.
Intervention effect corn changed soil water by −1.3 mm in the second year after alfalfa conversion.
Intervention effect fallow following millet changed soil water by 4.9 mm in the second year after alfalfa conversion.
Recommendation Potatoes were judged the best rotation choice for restoring soil water.
Intervention effect Rotation treatments gave lower soil total nitrogen by 9.9% in 2001 than continuous alfalfa.
Intervention effect Rotation treatments gave lower soil total nitrogen by 21.5% in 2002 than continuous alfalfa.
Intervention effect Rotation treatments gave lower soil organic matter by 46.8% in 2001 than continuous alfalfa.
Intervention effect Rotation treatments gave lower soil organic matter by 28.1% in 2002 than continuous alfalfa.
Intervention effect Rotation treatments gave higher soil mineral nitrogen by 27.2% in 2002 than continuous alfalfa.
Observation Soil total nitrogen and organic matter decreased greatly in cornfields.
Recommendation Without fertilizer, spring wheat might best maintain soil fertility after alfalfa conversion.
Recommendation Planting corn and other nutrient-demanding crops should be avoided after alfalfa conversion without fertilizer.

Modeling the Influence of Floriculture Effluent on Soil Quality and Dry Matter Yield of Wheat on Vertisols at Debre Zeit, Ethiopia

Mesfin Kebede; Sheleme Beyene; Yifru Abera Journal of environment and earth science 2012

Other claims from this paper (9)

Observation Floriculture effluent had high pH, EC, macronutrients and basic cations, but low micronutrients and heavy metals.
Intervention effect Effluent application did not significantly change soil texture or water holding capacity.
Observation Field capacity, permanent wilting point and WHC declined in sterilized and non-sterilized soils.
Intervention effect Effluent additions significantly increased soil pH, EC, exchangeable bases and micronutrients after both harvests.
Intervention effect Wheat shoot dry weight was significantly affected by increasing effluent volume.
Intervention effect In non-sterilized soil, low effluent volume increased wheat shoot dry weight.
Observation Wheat shoot dry weight subsequently decreased as effluent additions continued.
Observation Continuous increases in pH, CEC and ESP changed neutral soil to saline soil.
Intervention effect Effects of effluent on wheat performance and soil quality were more pronounced in sterilized soil.
