tailieunhanh - Evaluation of sesuvium portulacastrum for the phytodesalination of soils irrigated over a long-term period with paper mill effluent under non-leaching conditions
Paper and pulp mills discharge large volumes of wastewater into the environment. Crop productivity can be improved by using this wastewater, which is rich in salts and nutrients, as an irrigation source improves crop productivity by supplying enormous amount of nutrients. But for a long termit leads to development of soil salinity and sodicity and also calcareousness. Since leaching of salt affected soils with good quality water is impossible because of its non-availability in the study area, an attempt was made in the present study with the technique of phytodesalinisation using halophytes for remediation. Sesuvium portulacastrum, a facultative halophyte is widely studied for its phyto-desalinisation capacity of salt affected soils. | Evaluation of sesuvium portulacastrum for the phytodesalination of soils irrigated over a long-term period with paper mill effluent under non-leaching conditions
