  • Zonejection: Conservation tillage manure nutrient delivery system

    Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

  • Conservation versus conventional tillage on performance of three different crops

    Conservation tillage, besides being more economical, prevents soil erosion and has other beneficial effects on our environment, but few studies have been conducted on differential responses of different crops to conservation tillage. The main objective of this study was to examine the interaction of tillage with crop species. Rainfed field experiments in a strip-plot design with four replicates ...

  • Effect of tillage and rainfall on transport of manure-applied cryptosporidium parvum oocysts through soil

    Received for publication September 30, 2008. Most waterborne outbreaks of cryptosporidiosis have been attributed to agricultural sources due to the high prevalence of Cryptosporidium oocysts in animal wastes and manure spreading on farmlands. No-till, an effective conservation practice, often results in soil having higher water infiltration and percolation rates than conventional tillage. We ...

  • In-situ soil moisture conservation: utilisation and management of rainwater for crop production

    The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally ...

  • Economic performance of alternative tillage systems in the northern corn belt

    While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation benefits of NT while maintaining productivity and economic returns. The objectives of this study were to ...

  • Conservation: It’s the right thing to do

    A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way it ...

  • Fate and effects of clothianidin in fields using conservation practices

    Despite the extensive use of the neonicotinoid insecticide clothianidin, and its known toxicity to beneficial insects like pollinators, little attention has been given to its fate under agricultural field conditions. The present study investigated the fate and toxicity of clothianidin applied every other year as a corn seed‐coating at two different rates, i.e., 0.25 and 0.50 mg/seed, in an ...

  • Effectiveness and efficacy of conservation options after potato harvest

    Soil erosion and phosphorus (P) runoff can be severe in potato production systems in the Northeast USA, which are characterized by intensive tillage, minimal ground cover, low crop residue return, and steep slopes. We used rainfall simulators in the greenhouse and field to assess sediment and P movement associated with two conservation practices: straw mulching and application of polyacrylamide ...

  • 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 ...

  • Tillage requirements for integrating winter-annual grazing in peanut production: plant water status and productivity

    The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with ...

  • Impact of varying planting Dates and tillage systems on cotton growth and lint yield production

    As economic conditions deteriorated, cotton (Gossypium hirsutum L.) producers have looked to improve profit margins by reducing inputs while maintaining yields. Pairing the yield benefits from early planting with the input reductions from conservation tillage might help accomplish those goals. The objective was to determine how growth, lint yield, and fiber quality were impacted by planting ...

  • Five Ways to Manage the Soil for Planting

    The soil, as the primary resource for food production and the most important tool for every farmer, is crucial for farming. Successful farming begins with the quality soil, which provides water and essential nutrients to the crops. Rich and healthy soil, combined with the appropriate amount of water and sunlight can significantly contribute to global food production. Proper soil management ...

  • Soil water content and soil disaggregation by disking affects PM10 emissions

    Row crop agriculture in California's San Joaquin Valley is a major contributor of particulate matter <10 µm in aerodynamic diameter (PM10). The California Air Resources Board uses fixed PM10 emission values for various tillage operations to monitor and design attainment strategies. However, fixed emission values do not reflect emissions produced by a single implement operating under different ...

  • Soil management practices for sustainable agro-ecosystems

    A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today’s agricultural technologies may be increasing productivity to meet world food demand, but they may also be threatening agricultural ecosystems. For the global environment, agricultural systems provide both sources and ...

As a result, US agricultural, natural resources and environmental legislation and corresponding federal rules and regulations are more scientifically sound and appropriately ...

  • How a new way of thinking about soil sparked a national movement in agriculture

    For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...
