Soybean responds to amelioration of sodic soils using polyacrylamides
Sivapalan, Siva (2003) Soybean responds to amelioration of sodic soils using polyacrylamides. Irrigation Australia, 18, pp. 45-47.
More than half of the land area used for cropping in Australia is affected by sodicity. In most of these soils, the yield is restricted to less than 50 per cent of the potential yield determined by the climate. As a result, there is a widespread net production loss which is believed to cost several million dollars each year. As irrigation water is becoming increasingly limited in Australia, it is vital to improve the water use efficiency of crops grown under irrigated conditions. Using PAM in sodic soils has potential not only to improve crop production, but also to minimise environmental impacts such as soil erosion and turbidity of water.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
