“…A cover crop is a transition crop between two production systems, and it has the potential to provide multiple benefits, such as preventing soil erosion, improving soil physical and biological properties, supplying nutrients, suppressing weeds, improving the availability of soil water, and breaking pest cycles. Many researchers have emphasized that cover crops increase soil organic matter, infiltration rate, and nitrogen fertilizer use efficiency (Bordovsky et al, 1999;Veenstra et al, 2007;Li et al, 2008). In contrast, several other researchers (Balkcom et al, 2007;Dabney et al, 2001) reported a potential disadvantage of reducing soil water for subsequent cash crops when growing cover crops.…”

ABSTRACT. Interest in cover crops has been increasing in the Texas (1) irrigated cotton without a cover crop (CwoC-I), (2) irrigated cotton with winter wheat as a cover crop (CwC-I), (3) dryland cotton without a cover crop (CwoC-D), and (4) dryland cotton with a winter wheat cover crop (CwC-D) at the Texas A&M AgriLife Research Station at Chillicothe from 2011 to 2015. The average percent error (PE) between the CSM-CROPGRO-Cotton simulated and measured seed cotton yield was -10.1% and -1.0% during the calibration and evaluation periods, respectively, and the percent root mean square error (%RMSE) was 11.9% during calibration and 27.6% during evaluation. For simulation of aboveground biomass by the CSM-CERES-Wheat model, the PE and %RMSE were 8.9% and 9.1%, respectively, during calibration and -0.9% and 21.8%, respectively, during evaluation. Results from the long-term (2001-2015) simulations indicated that there was no substantial reduction in average seed cotton yield and soil water due to growing winter wheat as a cover crop.

“…Irrigation has been observed to affect the soil organic matter of some Great Plains soils. Bordovsky et al (1999) found that irrigation led to increases in total C for semi-arid sandy soils in Texas, while Lueking and Schepers (1985) observed increased total C for sandy soils in Nebraska. Williams (2001) observed increased SOC with irrigation for drier upland soils, and no increase for wetter lowland soils in a study conducted on fine-textured soils of Konza Prairie in eastern Kansas.…”

“…Under spring wheat and barley production systems common in many areas of the western United States, the time between harvest and planting is much longer (8-10 months), thus the time for residue breakdown is longer. Bordovsky et al (1999) reported the SOC concentration in the top 7.5 to 10 cm of soil for a continuous wheat system under both reduced tillage and conventional tillage, and the wheatsorghum double crop (Table 4). The SOC concentration was determined in 1982, 1985, and 1987 …”

Abstract:The effects of straw removal from irrigated fields cropped to wheat and barley on soil properties and nutrient cycling are a concern because of its potential impact on the sustainability of agricultural fields. The increasing demand of straw for animal bedding and the potential development of cellulosic ethanol production will likely increase the demand in the future. Previous reviews addressing changes in soil properties when crop residues are removed focused primarily on rain-fed systems. This article reviews published research assessing the effects of wheat and barley straw removal on soil organic carbon (SOC) and analyzes changes in nutrient cycling within irrigated wheat and barley production systems. The effects of straw removal on bulk density, saturated hydraulic conductivity, and other properties are reported from selected studies. Six studies compared SOC changes with time in irrigated systems in which wheat straw was removed or retained. These studies indicated that SOC either increased with time or remained constant when residues were removed. It is possible that bclowground biomass was supplying C to soils at a rate sufficient to maintain or, in some cases, slowly increase SOC with time. A separate research review calculated the minimum aboveground annual carbon inputs needed to maintain SOC levels from nine wheat system studies. Calculations of the minimum aboveground annual C source inputs needed to maintain SOC levels were from rain-fed systems and are some of the best information presently available for use in evaluating residue removal effects in irrigated systems. However, long-term studies are needed to obtain reliable data for diverse irrigated systems. Significant amounts of nutrients are removed from the soil/plant system when straw is removed. Producers will need to determine the cost of the nutrient removal from their systems to determine the value of the straw.Key words: Straw, residue, wheat, barley, small grain, soil organic carbon, nutrients, fertilizer (Soil Sci 2009:174: 303-311) R emoval of straw from grain production fields that have historically incorporated the residues with tillage have many interested parties concerned about the effects on soil properties and nutrient cycling. Several changes and potential changes in straw management have led to these concerns, including removal of straw from grain fields for animal bedding and feed, increased costs of fertilizers and fuel, and the potential development of cellulose-based ethanol production. Because of potential increases in biofuel demand, the ethanol industry will likely be a major cause of more residue removal from cropland. The immediate and long-term effects of removing aboveground crop residues from fields on crop productivity and sustainability are a concern. A series of policies have pushed for the increased production of biofuels, including the
