Evaluation of climate change impacts and adaptation strategies for maize cultivation in the Himalayan foothills of India
This study evaluates the impacts of climate change on rainfed maize (Zea mays) yield and evaluates different agro-adaptation measures to counteract its negative impacts at Sikkim, a Himalayan state of India. Future climate scenarios for the 10 years centered on 2025, 2055 and 2085 were obtained by downscaling the outputs of the HadCM3 General Circulation Model (GCM) under for A2 and B2 ...

The effect of poultry manure application rate and AlCl3 treatment on bacterial fecal indicators in runoff
Increasing costs associated with inorganic fertilizer have led to widespread use of broiler litter. Proper land application, typically limiting nutrient loss, is essential to protect surface water. This study was designed to evaluate litter-borne microbial runoff (heterotrophic plate count bacteria, staphylococci, Escherichia coli, enterococci, and Clostridium perfringens) while applying ...

Nitrate leaching in two irrigated soils with different rates of cattle manure
Received for publication December 15, 2008. Manure applied to irrigated land may potentially contaminate groundwater with NO3–N. An 8-yr field experiment was conducted in southern Alberta, Canada, to determine the effects of different rates of manure on NO3–N accumulation in two irrigated soil types and NO3–N leaching to shallow groundwater. An annual cereal silage was grown at each site and ...

Rainfall simulation in greenhouse microcosms to assess bacterial-associated runoff from land-applied poultry litter
Runoff water following a rain event is one possible source of environmental contamination after a manure application. This greenhouse study used a rainfall simulator to determine bacterial-associated runoff from troughs of common bermudagrass [Cynodon dactylon (L.) Pers.] that were treated with P-based, N-based, and N plus lime rates of poultry (Gallus gallus) litter, recommended inorganic ...

Transport of lincomycin to surface and ground water from manure-amended cropland
Livestock manure containing antimicrobials becomes a possible source of these compounds to surface and ground waters when applied to cropland as a nutrient source. The potential for transport of the veterinary antimicrobial lincomycin to surface waters via surface runoff and to leach to ground water was assessed by monitoring manure-amended soil, simulated rainfall runoff, snowmelt runoff, and ...

VR manure spreading
Variable rate manure spreading could be a good option for your farm Today’s fertilizer prices may be just the incentive needed for some farmers to explore the benefits of variable rate manure spreading. Manure can be a rich source of nitrogen, phosphorous and potassium, as well as trace nutrients. It has the additional benefit of improving soil quality by boosting ...

Crop productivity and economics during the transition to alternative cropping systems
Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop production. This study examined crop yields, input costs, and economic returns during the transition to a range of cropping system alternatives in the northern Corn Belt region, including different system ...
