Changes in physico-chemical-properties of soils fertilized by agro-industrial residues

Cyclic fertilization of two soils by olive oil-mill sludge compost (alpechin) and vinasse, improved their agrotechnical properties. THESE soils were classified as Typic Xeropsamment and Typic Xerorthent. The effect of fertilization was studied by X-ray diffraction, and measurement of water sorption...

Descrição
Resumo:Cyclic fertilization of two soils by olive oil-mill sludge compost (alpechin) and vinasse, improved their agrotechnical properties. THESE soils were classified as Typic Xeropsamment and Typic Xerorthent. The effect of fertilization was studied by X-ray diffraction, and measurement of water sorption and water retention from gaseousphase. Incorporation of fertilizers increased both water sorption and water retention, especially in case of sandy soil. Relative calcite content in the clay and silt fractions was changed after addition of fertilizer, this distribution was dependent on soil type.
