Soil organic carbon (SOC) and nitrogen (N) fractions greatly affect soil health quality. This study explored the effects of wheat straw incorporation on Chinese rice paddy fields with four treatments: (1) a control (CK), (2) mineral NPK fertilizer (NPK), (3) moderate (3 t ha?1) plus (MSNPK), (4) high (6 (HSNPK). In total, 0–5, 5–10, 10–20, 20–30 cm depths were sampled from in China. Compared CK...

This study is to investigate three common potential setup uncertainties during Linac commissioning and annual QA and to evaluate how these uncertainties propagate into the quality of beam profiles and patient dosimetry using gamma analysis. Three uncertainty scenarios were purposely introduced for gantry position tilted from 0 ̊ 3 ̊ (scenario 1), isocenter position misaligned from 0 6 mm (scenari...

Physical, chemical and biological attributes of soil surface are significantly affected by tillage practices and crop rotation. The objective of this study was to determine the short-term (2006-2009) effects of conventional and conservational tillage practices on selected soil physical properties of a heavy clay soil under two wheat-corn and wheatlegume rotation in a semi-arid Mediterranean...

Understanding the fates of soil hydrological processes and nitrogen (N) is essential for optimizing the water and N in a dryland crop system with the goal of obtaining a maximum yield. Few investigations have addressed the dynamics of dryland N and its association with the soil hydrological process in a freeze-thawing agricultural area. With the daily monitoring of soil water content and acquis...

Vegetation type is known to affect soil organic carbon (SOC) storage. However, the magnitudes and distributions of SOC sequestration driving factors for different vegetation types are still largely unknown. Thus, we studied changes in fractions along profiles restoration their relationships with properties. We selected five collected samples from depth intervals 0–10, 10–30, 30–60, 60–90 cm. Fi...

Health of any soil is influenced by its physical properties to greater extent which has been more prominent in Vertisols due their self-till behavior. Differential application nutrients long-term may alter the at temporal and spatial scales. Inventory on effect different nutrient management practices across depths, especially central India, insufficient. Present study examined (48 years) combin...

Dispersion, dissipation, and efficacy of gas and gel formulations of methyl bromidechloropicrin (202, 269, 336, and 403 kg/ha) on nematodes and weeds on tomato were studied in field plots. Concentrations of methyl bromide and chloropicrin 4 hr after soil treatment were greater at a depth of 15 cm than at 30, 45, or 60 cm. The concentrations of both chemicals decreased with lower doses, greater ...

Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface soil has been a primary concern in the past decades, however it remains poorly understood about the adaptive response of microbial communities along the profile during ecological restoration of the tailings. In this study, microbial communities along a 60-cm profile were ...
