Ammonia volatilization from Vertisols
European Journal of Soil Science, 2002Summary Farmers want to minimize losses of nitrogen (N) by volatilization of ammonia when adding fertilizers and improve fertilizer recovery of N by plants. We aimed to quantify the losses of N through NH 3 volatilization as affected by soil moisture content, type of ...

Micromorphology of Cracking Clayey Soils (Vertisols)
1990Abstract Mechanical soil movement is the most characteristic process in Vertisols and in some related clayey soils. Swell-shrink of 2:1 lattice clays on wetting and drying results in characteristic macro-morphological features and in micromorphological surface-related plasmic fabrics.

Zinc buffer capacity of vertisols
Australian Journal of Soil Research, 1994The soil Zn buffer capacity is an important factor that regulates the concentration of plant-available Zn in soil solution. It is measured variously as Zn buffer power, Zn sorption or Zn desorption capacity. This study was conducted to determine Zn buffer power, and Zn sorption capacity and Zn desorption capacity in Vertisols as influenced by soil ...

Counting viableAzotobacter chroococcum in vertisols
Plant and Soil, 1989On compare six methodes de preparations du sol pour le comptage d'Azotobacter chroococcum dans les vertisols. La meilleure technique pour preparer la solution de sol consiste a agiter avec 10% de sable grossier dans l'eau distillee pendant 30 minutes pour provoquer une desagregation ...
