Year, region, and temperature effects on the quality of Minnesota`s soybean crop
Bulk commodity soybean [Glycine max (L.) Merr.] can now be sourced with great specificity through rail and container purchases. The objective of this study was to determine whether analyses of farmer-grown soybean seed samples could detect significant regional differences in soybean quality traits. Through analysis of 2706 farmer volunteered soybean samples representing harvests from 2003–2005, ...

Sugarcane response to mill mud, fertilizer, and soybean nutrient sources on a sandy soil
Improving soil organic matter and soil fertility are important factors in the sustainability of sugarcane (Saccharum spp.) production. A 3-yr field trial was established in 2004 on a sandy Alfisol in Florida to compare the effect of organic and inorganic nutrient sources on sugarcane production. The three nutrient sources were (i) mill mud (filter cake, cachaza), (ii) local standard fertilizer, ...

The income and production effects of biotech crops globally 1996-2009
This paper provides an assessment of the economic impact at the farm level of agricultural biotechnology on global agriculture. It examines the economic impacts on yields, key costs of production, direct farm income, indirect (non-pecuniary) farm level income effects and impacts on the production base of the four main crops of soybeans, corn, cotton and canola. The analysis shows that there have ...

Estimating the contribution of groundwater to rootzone soil moisture
In the Huaibei Plain basin, China, soybean is a main crop. During the soybean growth period, rainfall can vary largely and depth to watertable can also vary largely. The amount of water supplied to the soybean rootzone by groundwater affects soybean growth and yield. Accurate simulation of groundwater contributions to soybean rootzone soil moisture (groundwater contribution) can be important ...

Growing demand for soybeans threatens Amazon rainforest
Some 3,000 years ago, farmers in eastern China domesticated the soybean. In 1765, the first soybeans were planted in North America. Today the soybean occupies more U.S. cropland than wheat. And in Brazil, where it spread even more rapidly, the soybean is invading the Amazon rainforest. For close to two centuries after its introduction into the United States the soybean languished as a curiosity ...

The lack of clear GMO regulation: its impact on researchers and farmers in Brazil
This paper discusses the current regulation of genetically modified organisms and derivatives used in Brazil, where GM-plants are on the verge of being approved for commercial use. The paper further uses a simulation model to assess the potential economic benefits resulting from unrestricted commercial approval of herbicide-tolerant soybeans and some other crops on the Brazilian economy. Only ...

Soil carbon levels in irrigated western corn belt rotations
Proposals promoting the use of massive amounts of crop residues and other lignocellulosic biomass for biofuel production have increased the need for evaluation of the sustainability of cropping practices and their effect on environment quality. Our objective was to evaluate the effects of crop rotation and N fertilizer management and their stover production characteristics on soil organic carbon ...

Self-seeded cereal cover crop effects on interspecific competition with corn
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereal cover crops were planted in varying row spacing configurations and ...

Rotational effects of cuphea on corn, spring wheat, and soybean
Diversifying crop rotations can give economic and environmental benefits. Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) is a new oilseed crop that grows well in the Corn Belt. However, little is known about its rotational effect on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and spring wheat (Triticum aestivum L.), which are predominant crops in this region. A 4-yr study ...

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. ...

Cottonseed Oil Press Machine
Cottonseed oil expeller machine is mainly composed of electrical control, automatic heating, adjustment, transmission, and vacuum oil filter. The screw is carburized by alloy steel to enhance surface hardness and wear resistance. The platter is ground by the surface grinding machine to ensure the finishing coat and increase the oil output. The surface of the machine is treated with stainless ...

A closer look at AMCO’s versatile Ditcher cutter heads
Standing water can kill crops in a hurry. That’s why a well-built drainage system is essential, especially if you: Live in a flat area or region with a lot of precipitation Plant corn, soybeans, cotton, rice, or other crops that are sensitive to waterlogging AMCO’s Vertical and Offset Rotary Ditchers are affordable tools that easily clean roadside ditches and reshape waterways. ...

Can corncob be made into briquettes?
Corncobs, like other agricultural and forestry wastes, are biomass resources that can be recycled, such as sawdust, crop stalks (corn stalks, soybean stalks, sorghum stalks, cotton stalks, rape stalks, peanut stalks, sunflower stalks), chaff, and grass. Grass, shrub branches, bamboo truncated, material head, bagasse, etc. The common feature of these biomass raw materials is that they contain a ...

AquaCrop model simulation under different irrigation water and nitrogen strategies
On a global scale, irrigated agriculture consumes about 72% of available freshwater resources. Deficit irrigation can be applied in the field to save irrigation water and still lead to acceptable crop production. The AquaCrop model is a simulation model for management of irrigation and nitrogen fertilizer. This model is a new model that is accurate, robust and requires fewer data inputs ...

Establishment and growth of self-seeded winter cereal cover crops in a soybean–corn rotation
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereals were planted and managed chemically and mechanically in varying ...

In-Furrow inoculation and selection for higher motility enhances the efficacy of bradyrhizobium japonicum nodulation
The issue of competition for nodulation has received much attention in studies on soybean [Glycine max (L.) Merr.] crops because native soil rhizobia often preclude nodulation of inoculated high-quality strains. In this work, soil placement and enhanced motility of Bradyrhizobium japonicum were investigated as strategies to improve the competitiveness of soybean inoculants applied in the presence ...
