oa Agrochemophysica - The stabilisation of apedal fine sandy soils with polyvinyl alcohol

Volume 13, Issue 1
  • ISSN : 0302-7112



Polyvinyl alcohol was incorporated in fine sandy soils of the Vaalharts Irrigation Scheme in order to form stable aggregates. The successful stabilisation of aggregates depends to a large extent on the degree of mixing of the soil and polymer solution. A multiple regression equation was established with which the percentage water stable aggregates can be predicted from PVA concentration and clay content as input variables.
