application of superabsorbent material is one of the new methods for moisture storage in the soil. this research was performed in the khajeh research station on the basis of randomized complete block design with three replications in the plots with dimension of 4×5 meter for investigate the effect of different amounts of pumice on water retention capacity in the soil, growth and of spring saffl...

Various applications such as meteorology, climatology or hydrology require information about the soil hydraulic properties over large areas. Microwave radiometry is a promising approach to gather this type of information. The microwave emission from soils is strongly affected by the roughness of the soil surface. This effect has therefore to be quantified to get a reasonable estimation of the h...

Previous research has shown that treatment of poultry litter with alum is an effective management strategy to reduce phosphorus (P) solubility in litter thereby reducing potential P losses to surface runoff after surface applications. However, limited data are available evaluating alum-treated poultry litter (ATPL) environmental impact in cultivated systems and how its application will affect c...

application of additives on soil surface has been considered to control runoff and soil erosion as well as the necessity of recycling. however, application of the environmentally-friendly techniques has been less taken into consideration. hence, the present study was planned to determine the effect of combination of vermicompost (24 g) with sugarcane vinasse (22 cm3) on runoff and soil loss at ...

Two incubation experiments were conducted under controlled moisture and temperature conditions to determine the effects of soil amendment treatments based on pruning waste biochar and oyster shell, on N2O and CO2 emissions from an orchard soil. In experiment 1, four treatments were tested including, control (CK), pruning waste biochar at 2% (B2%), at 10% (B10%), and oyster shell (OS), mixed wit...

determined accurately (Blackmer and White, 1998) and for low cost (Wolf and Buttel, 1996; Lu et al., 1997). The surface soil organic C (SOC) concentration is a useful soil The dark color of soil is typically associated with high property to map soils, interpret soil properties, and guide fertilizer organic-matter concentration and high native fertility. and agricultural chemical applications. T...

Wind erosion and dust storms are main issues in arid and semi-arid regions. Application of soil stabilizer on unstable land might be an eff ective and sustainable strategy in arid and semi-arid countries to minimized harmful eff ects on environment and human health. Th e aim of this study was to assess the eff ect of using nanoclay for increasing soil stability, as a result of increasing in siz...

In this paper, a soil moisture estimation model was developed to calculate the nationwide soil moisture fields using on site soil moisture observation, precipitation, surface temperature, MODIS NDVI and a data mining technique, Classification And Regression Tree (CART) algorithm and neural networks. The model was applied to the Yong-dam dam basin since the soil moisture observations of the Yong...

A greenhouse experiment has been planned for this study to delineate the benefits of two types of rice husk biochars (namely B300 and B600 which are prepared at 300°C and 600°C, respectvely) and coal fly ash (CFA), as soil amendments, for decreasing the amount of some heavy metals (like Pb, Cd, Ni, Cr, and Cu) as well as mobility and phytoavailability in an artificially-calcareous multi-element...
