  • Stability of soil structure for water movement in an aridisol

    Creator:
    Ali, Safdar
    Abstract:
    Lack of stability of soil aggregates for water movement is a major problem in arid soils due to low organic matter and higher sodium contents. Soil amendments for improving stability of structure and increasing infiltration of water are essential to solve water management problems in these areas. Different rates of...

  • Water soluble organic fractions in sewage sludge amended soil : characterization and binding mechanisms with copper (II)

    Creator:
    Lim, Hyungsik
    Abstract:
    Application of sewage sludge to soils increases the trace metal content and the organic content of soils. The complexation of indigenous and added metals with organic constituents must be studied to evaluate metal availability to plants and animals. The water soluble organic fractions (WSOF) from an agricultural soil (W), a...
