  • Effects of changes in climatic variables on maize crop water requirements in Huang–Huai–Hai watersheds, China

    The study of crop water requirements (CWR) under climate change is critical for reasonable crop irrigation. In the present study, the effects of changes in climatic variables from 1961 to 2010 on maize CWR in Huang–Huai–Hai (HHH) watersheds in China were investigated. Five daily climatic factors including maximum temperature (Tmax), minimum temperature ...

  • Rake In Greater Capacity And Higher Hay Quality

    It’s been said that the steel-toothed dump rake was first introduced in the 1860s. Of course, the process back then was to rake hay into piles, which were then pitched onto a wagon for transport to a haystack or the barn loft. To make windrows for the balers that came later, the operator simply spaced the “dumps” equally so they lined up in the field. The irony is that until ...

  • Comparison of runoff quantity and quality under annual cropping and forages

    Conversion from annual cropping to perennial forages may be a beneficial management practice (BMP) to reduce runoff quantity and improve surface water quality. Runoff variables were determined in two 30 ha producer's fields over 4 years (2004–2007) using a rainfall simulator. Field 1 was cropped to barley (Hordeum vulgare L.) in 2004 and then an alfalfa (Medicago sp.) and grass mix used for ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Second harvest timing and cut height of forage crops in Central Alaska

    Proper timing of second harvest is critical for good yields and long-term sustainability of perennial hay crops in high latitude environments. We studied effects of second harvest timing and height on yield and forage quality for smooth bromegrass (Bromus inermis Leyss.), alfalfa (Medicago sativa L.), and cicer milkvetch (Astragalus cicer L.) in central Alaska. Second harvest treatments occurred ...

  • Accounting for adaptation in assessing impact of climatic variations on crop yields: an empirical study of Arizona

    The goal of this paper is to analyze the impacts of climatic variation around current normals on crop yields and explore corresponding adaptation effects in Arizona, using a unique panel data. The empirical results suggest that both fertilizer use and irrigation are important adaptations to climate change in crop production. Fertilizer use has a positive impact on crop yields as expected. When ...

  • Organic and conventional production systems in the Wisconsin integrated cropping systems trial: ii. economic and risk analysis 1993–2006

    This article, the second in a series looking at the Wisconsin Integrated Cropping Systems Trial (WICST), reports on the profitability of six conventional and organic systems, with a focus on net returns and associated risk exposure. Several pricing scenarios were compared to evaluate the impact of government programs and organic price premiums. When net return estimates are made using only ...

  • Long-term agronomic performance of organic and conventional field crops in the mid-atlantic region

    Despite increasing interest in organic grain crop production, there is inadequate information regarding the performance of organically-produced grain crops in the United States, especially in Coastal Plain soils of the mid-Atlantic region. We report on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yields at the USDA-ARS Beltsville Farming Systems Project ...

  • Change in Surface Soil Carbon under Rotated Corn in Eastern South Dakota

    A diversified crop rotation may reduce fertilizer N inputs for corn (Zea mays L.) and increase soil organic C (SOC). Our objectives were to determine the effects of crop rotation and fertilizer N on soil C within the surface soil (0–15-cm depth). Rotations were started in 1990 on a Barnes sandy clay loam near Brookings, SD. Measurements of SOC began in 1996. Primary tillage since 1996 was chisel ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • Economics of five wheat production systems with no-till and conventional tillage

    Conventional tillage (CT) continues to be used on the vast majority of land seeded to monoculture winter wheat (Triticum aestivum L.) in the Southern Plains of the United States. In the region, wheat can be grown for either grain-only, forage-only, or for both fall–winter forage + grain (dual-purpose). This study was conducted to determine the net returns of five alternative wheat production ...

  • What makes farmers try new practices?

    Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others. A group of researchers at the University of Illinois wanted to know which farmers are most likely to adopt multifunctional perennial cropping systems -- trees, shrubs, or grasses that simultaneously benefit the environment and generate high-value products ...

  • Certified Organic Farm Relies on Compost

    Located 50 miles northwest of Dayton, Ohio, the owners of Fresh Aire Farms grow crops on over 250 acres of farmland, relying on high quality compost as a soil conditioner and nutrient amendment. Dan and Michelle Young started composting seven years ago to reduce the amount of chemical inputs they had to buy. “We are a certified organic farm incorporating sound cropping principles,” says Dan ...

  • Cattail plants’ Biomass as a bulking agent in sewage Sludge composting and the effect of the produced Compost on cattail plants’ Growth

    In every Greek island there is at least one town with more than 20,000 inhabitants. Several smaller towns and villages range from a few hundreds to a few thousands in population. Usually in the larger towns there are sewage treatment facilities providing at least secondary treatment of wastewater. In most cases the effluent produced is drained to the sea and the sludge is dumped in landfills. In ...

  • One Year Later · Persistent Herbicides in Compost

    ONE YEAR has passed since the Washington State University (WSU) composting facility and the Spokane Regional Compost Facility discovered traces of persistent herbicides in their composts. In Spokane, the source of contamination is a compound called clopyralid. Compost contamination at WSU initially involved the herbicide picloram, but clopyralid has since been detected in the compost also. In ...

  • Impact of Agri-environment measures

    The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...
