Soil Properties as Affected by Soil Conservation Practices and Soil Depths in Uwite Watershed, Hadero Tunto District, Southern Ethiopia

Tea yield and soil properties as affected by slope position and aspect in Lahijan area, Iran

Soil genesis, physico-chemical properties and tea yield were investigated along different hillslope positions in the major tea cultivation area of Iran, i.e. Lahijan, Gilan Province. Land suitability was also determined for the tea production in this hilly region. Four different slope positions i.e., summit, shoulder, backslope and toeslope were sampled on three slope aspects following the prof...

Soil genetics as affected by topography and depth of saline and alkali ground water under semiarid conditions in southern iran

Valuing Soil Conservation Benefits of Agroforestry Practices

Although advocates of agroforestry have promoted soil conservation as one of its primary benefits, empirical estimates of these benefits have been lacking due to temporal and spatial complexity of agroforestry systems and soil resource dynamics. This study aims to reduce this gap by designing and testing a three stage farm level productivity methodology for economic evaluation of soil conservat...

Soil Pore Characteristics, Hydraulic Conductivity and Soil Bulk Density as Influenced by Agroforestry and Grass Buffer Conservation Practices

Despite improvements in the use of soil conservation practices, crop rotation and nutrient management programs, significant concern still exists regarding soil erosion and nutrient losses in runoff from row crop production. In the US, states are required to implement water quality standards based on USEPA guidelines or other scientifically defensible methods (Ice and Binkley, 2003). Agroforestr...

Copper phytoavailability and uptake by Elsholtzia splendens from contaminated soil as affected by soil amendments.

Pot and field experiments were conducted to evaluate bioavailability of Cu in contaminated paddy soil (PS) and phytoremediation potential by Elsholtzia splendens as affected by soil amendments. The results from pot experiment showed that organic manure (M) applied to the PS not only remarkably raised the H2O exchangeable Cu, which were mainly due to the increased exchangeable and organic fracti...
