Each of Ohio's 467 soil series was assessed to determine the depth of the soil to bedrock, the depth to a limiting soil condition, the depth to seasonal saturation, and the soil permeability. Each soil series was placed into one of three categories; suited for traditional leach fields or mound systems, suited for mound systems only, or not suited for soil-based treatment. In a mound system, a l...

The objective of this study was to evaluate the effect of soil moisture condition and irrigation regime on the bioelectric potential of crops with different growth stages. The bioelectric potential of broccoli (Brassica oleracea var. italica) plants at the initial and mid-growth stages was measured under different soil moisture conditions and irrigation regimes using pot experiments. The result...

Reductive dechlorination is the primary pathway for environmental removal of pentachlorophenol (PCP) in soil under anaerobic condition. This process has been verified to be coupled with other soil redox processes of typical biogenic elements such as carbon, iron and sulfur. Meanwhile, biochar has received increasing interest in its potential for remediation of contaminated soil, with the effect...

Many global and regional climate modeling studies have demonstrated the importance of the initial soil water condition in their simulations of regional rainfall distribution. However, none of these modeling studies has been tested against directly observed data. This study tests the hypothesis that soil saturation is positively correlated with subsequent precipitation by analyzing a 14-year soi...

In order to evaluate the impact of physical and chemical properties of soil on Bekras kind wheat yield in the city of Arak, a completely randomized block experimental plan has been implemented with three replications in the1390 crop year. Treatments include the overall condition and qualifications of wheat field 's soil in 18 wheat farms, which were randomly selected. Traits in this experiment ...

Sensitivity analysis is critically needed to better understand the microwave emission model for soil moisture retrieval using passive microwave remote sensing data. The vegetation b-factor along with vegetation water content and surface characteristics has significant impact in model prediction. This study evaluates the sensitivity of the b-factor, which is function of vegetation type. The anal...

Peat and organic soils commonly occur as extremely soft, unconsolidated surficial deposits that are an integral part of the wetland systems. They may also occur as strata beneath other surficial deposits. These soils are problematic as they are very highly compressible and are of very low shear strength. In countries like Malaysia, peat and organic soils are found in abundance. Utilization of t...

The aim of this work was to establish the effect of the dose of liquid cow manure (LCM) on some chemical properties and biological activity in an Andisol. This study was carried out under laboratory conditions using an Andisol and LCM from a dairy farm located in the South of Chile. The dose of LCM were the equivalent to 0 (S0), 100 (S100), 200, (S200) and 300 (S300) thousand L ha. This amount ...
