Short-Term Effects of Tillage on N Mineralzation from Farm Yard Manure in Semi-Arid Tropical Vertisol
Decomposition management mineral N organic matter
2010/11/15
Tillage may have different effects on physical protection of organic matter during decomposition process. Short-term effects of tillage on N release from Farmyard manure (FYM) was studied during Augus...
Effect of soil compaction and organic matter on the early growth of maize (Zea mays) in a vertisol
vertisol organic matter compaction maize early growth
2008/11/20
A laboratory experiment was conducted to determine the emergence and early growth of maize (Zea mays) seeds in a dark clay soil known as vertisol (Typic Pellustert). Three quantities of groundnut hau...
Pedogenic Formation of High-Charge Beidellite in a Vertisol of Sardinia (Italy)
Beidellite High-charge Smectite Layers Illite-Smectite Mixed Layers Italy Smectite Soil Vertisol
2011/12/8
Abstract: The fine clay (<0.1 祄) fraction of a clayey soil (Vertisol) from Sardinia (Italy) was studied by means of X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, cation exch...
Low-Charge to High-Charge Beidellite Conversion in a Vertisol from South Italy
Beidellite Smectites Vertisol
2011/12/28
The fine silt (2? 祄) coarse clay (0.1? 祄) and fine clay (<0.1 祄) fractions of a Vertisol from South Italy were studied with X-ray diffraction. The most reactive fine clay (<0.1 祄) fraction was investi...
Optical Density of Vertisol Clay Suspensions in Relation to Sediment Volumes and Dithionite-Citrate-Bicarbonate-Extractable Iron
Beidellite Extractable Fe Fabric Optical density Tactoid Vertisol
2012/1/11
Clay fractions of eight vertisols and vertisolic soils from Israel were found to consist principally of a Fe-rich beidellite. Sediment volumes of Na-clay suspensions, obtained in measuring cylinders a...
