Twenty years of research on reclamation of salt-affected soils in Romanian rice fields

The physiological particularities of rice enable this plant to obtain its necessary oxygen for the roots through stems. This characteristic permits the use of rice during the reclamation of salt-affected soils with ponded flooding. This paper presents some results of twenty years of research in Romania, on the reclamation of saline and sodic soils under rice, including requirements for soil drainage, soil amendments, and salt leaching, at different stages of the reclamation period.Specific data are provided on the tolerance of rice to salinity, crop rotation in rice fields, fertilization, and irrigation practices.
