Physically degraded lands are characterized with high graveliness and low nutrient status resulting in sparse vegetation hence, external supplementation of nutrients is essential for successful vegetation establishment. The soil pH and EC was similar to that of normal soil in degraded lands. However, the organic carbon and nutrient status were low in wastelands with higher BD of 1.62 gcc-1. The evaluation of different organic wastes such as paper mill sludge, sugar mill sludge, distillery sludge and municipal sludge along with FYM as a nutrient source for degraded lands reveled that N and P content was highest in sugar mill sludge followed by municipal sludge while K content and secondary nutrients such as calcium and sulphur were found highest in distillery sludge. In case of micro nutrients high levels of Fe (1550 ppm) and Mn (407 ppm) was observed in paper mill and sugar mill sludge, respectively. The Zn (2329 ppm) and Cu (448.4 ppm) were recorded in municipal sludge. The different organic sources were rated as sugar mill sludge, municipal sludge, distillery sludge, FYM, paper mill sludge.Keywords
