Abstract:
... An interest to grow cover crops is increasing in the semi-arid Texas Rolling Plains (TRP) region, where cotton (Gossypium hirsutum L.) is a major cultivated crop. Under conservation tillage systems, cover crops are expected to enhance ecosystem services, including improved soil health and erosion reduction. However, there is a concern that cover crops could deplete soil water content and affect th ...

Abstract:
... Tillage systems that reduce the number of cultivation steps can, according to soil scientists, save soil moisture, fuel, labor, and machinery costs, as well as reduce wind and water erosion. However, many producers in South Texas are reluctant to adopt these practices. The objective of this study was to compare the economics of conventional tillage (CT) and no-tillage (NT) systems on three commerc ...

Abstract:
... Management practices, such as no-tillage (NT) and high-intensity cropping sequences, have the potential to enhance C and N sequestration in agricultural soils. The objectives of this study were to investigate the impacts of conventional-tillage (CT), NT, and multiple cropping sequences on soil organic carbon (SOC) and nitrogen (SON) sequestration and on distribution within aggregate-size fractions ...

Abstract:
... The Texas Southern High Plains is a major cotton (Gossypium hirsutum L.) producing area wherea monoculture of conventionally tilled continuous cotton is thought to be causing a downward trend in yields. A factorial experiment with split plot design evaluated the main and interactive effects of (i) cotton-wheat (Triticum aestivum L.)-fallow rotation vs. continuous cotton, (ii) no tillage vs. conven ...

Crop management strategies that alter the timing, placement, quantity, and quality of crop residue input can affect the size, turnover, and vertical distribution of the active and passive pools of soil organic matter (SOM). Our objectives were to quantify long-term changes in soil organic, soil microbial biomass (SMB), and mineralizable C and N in continuous wheat (Triticum aestivum L.), continuou ...

Abstract:
... It is estimated that 20% of cotton producers in the Texas High Plains use the strip tillage practice of planting cotton (Gossypium hirsutum L.) in residues of chemically terminated winter wheat (Triticum aestivum L.). The effect of the residue on water use partitioning between soil (Eₛ) and crop (Ec) evaporation has not been reported. This study tested the hypothesis that the cumulative evapotrans ...

Abstract:
... Decomposition of sorghum [Sorghum bicolor (L.) Moench] and wheat (Triticum aestivum L.) plant residues can immobilize enough surface-applied N to cause a deficiency in successive winter wheat crops. This experiment examined the effects of conventional and no-till grain sorghum and wheat residues on N requirements of dryland winter wheat. Field experiments conducted from 1987–1991 on an Austin silt ...

Moench) cropping in 1985 and 1986 were evaluated in a field study on a Weswood soil (Fluventic Ustochrept) near College Station, Texas. Nitrogen-15-depleted NH4NO3 (150 kg N ha) was surface broadcast or subsurfa ...
