Agroforestry Buffers Reduce Runoff from Agricultural Watersheds
Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective of this study was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop ...

The application of CULTAN technology for feeding row crops
2020 year, heavy rains in early spring and subsequent drought right until the harvesting period. Even in this difficult period, MAXIMARIN multi-injection mechanisms for application of UAN fertilizers into the soil have proved their efficiency for early grain ...

Intersex (testicular oocytes) in largemouth bass (Micropterus salmoides) on the Delmarva Peninsula, USA
We describe the prevalence and severity of intersex in the form of testicular oocytes (TO) in largemouth bass (Micropterus salmoides; LMB) collected over a 5 yr period from a variety of surface waters on the Delmarva Peninsula, USA, a region dominated by poultry production and agricultural land‐use. During a 2005–2007 survey of approximately 200 male specimens representing 6 fish and 2 frog ...

Anisotropic flow resistance theory and experimental verification on partially submerged crop vegetation
The presence of orderly arranged rows and spacing of crop vegetation increases the anisotropy of the Earth's surface, and affects the resistance of the surface to overland flow. However, few studies have addressed how the orderly arrangement of crop vegetation affects the resistance of the surface to overland flow. In the present study, we consider that flow resistance has anisotropic ...

Likely impacts of biofuel expansion on Midwest land and water resources
US ethanol production should exceed 12 billion gallons by 2010, and EISA 2007 mandates 36 billion gallons by 2022, diverting one-third of corn to ethanol and 13% of soybean production to biodiesel. Increased demand will ricochet through other agricultural sectors and alter production patterns and land use in the Corn Belt. This paper discusses effects of biofuel expansion on land and water ...

Improving soil nutrition with poultry litter application in low-input forage systems
Despite high volumes of manure production in the Shenandoah Valley of Virginia, there are still areas of forage production that are nutrient deficient because manures have traditionally been applied to higher-value row crops. This study was conducted to compare the effects of poultry litter and inorganic fertilizers on soil fertility and forage production. Two sites had the same treatments ...

Living mulch forage yield and botanical composition in a corn-soybean-forage rotation
Managing forages as living mulches during row crop production requires suppressing the forages to produce economical crop yields. The objective of this research was to identify forage plants with varied growth habit, persistence, and yield potential to provide desirable ecosystem functions in a multifunctional cropping system. Alfalfa (Medicago sativa L.), kura clover (Trifolium ambiguum Bieb.), ...

Soybean response to inoculation and nitrogen application following long-term grass pasture
Current demand for soybean grain [Glycine max (L.) Merrill] may lead to a conversion of pasture and Conservation Reserve Program fields into soybean or corn (Zea mays L.) production. Our objective was to determine the effect of soybean seed inoculation with Bradyrhizobium spp. and fertilizer N application rate on soybean productivity planted 1 and 2 yr after conversion to row crop production. ...

Scouting for pest in Iowa cover crops
Landscape diversification, including the use of cover crops, can provide habitat and forage for beneficial insects. This is especially true in the spring when there is a lack of food. Alternatively, cover crops can also support field crop pests, including moths, beetles, flies and slugs. The early spring vegetation, sometimes called a “green bridge,” provides resources until the row ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

Dairy farm New Mexico, USA
Type of Wastewater System: Facility to Lagoon For Solid and Wastewater Collection Problem: This facility has an expensive liner in its lagoon, and the use of equipment to remove the solids from the lagoon was not an option. It also dewaters the lagoon via irrigation onto row crops every 30 days. The buildup of solids in the lagoon had reached a point of capacity such that they were unable to ...

Evaluating cumulative effects of anthropogenic inputs in Prince Edward Island estuaries using the mummichog (Fundulus heteroclitus)
Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...

Skip-row and plant population effects on sorghum grain yield
In environments with limited rainfall, skip-row configuration (planting one or a group of rows alternated with rows not planted) under rainfed conditions may increase yield of grain sorghum [Sorghum bicolor (L.) Moench] due to conservation of soil water between widely-spaced crop rows that is not accessed until late in the growing season. A field study was conducted over 10 site-years in Nebraska ...

Do-It-Yourself Field Tiling
At a time when grain markets continue to strain row crop revenue potential, many farmers are taking steps to do all they can to maximize productivity and yields. Excess water is a common yield robber with corn and other crops. For farmers with heavy, moisture-retaining soils, or slow draining areas in a field, installing drainage tile can improve overall productivity. Additional drainage tile ...

Your Cereal Seeding Rate Matters Too
24 years ago when I first started in this business, almost every farmer planted canola at exactly the same rate. No matter how sandy or loamy, high or low moisture, productive or thin-yielding the land, and no matter how plump or slim the seed, we planted 10 acres to the bag. But, because canola seed is expensive and canola companies were invested in optimal production, seeding rate practices ...

How farm policy used to work
In the period between the 1930s and 1992, farm bills generally instituted compensation policies that took the form of price supports. These policies were designed to manage the surplus production that resulted from centuries of developmental policies while allowing U.S. farmers the chance, with hard work and good management skills, to provide their family with a livelihood. Compensation policies ...

Can We Prevent A Food Breakdown?
By Lester R. Brown As food supplies have tightened, a new geopolitics of food has emerged—a world in which the global competition for land and water is intensifying and each country is fending for itself. We cannot claim that we are unaware of the trends that are undermining our food supply and thus our civilization. We know what we need to do. There was a time when if we got into trouble ...
