| dc.description.abstract | Anthropogenic liquid waste collected from Ecosan toilet, was slightly alkaline in reaction with high soluble salts and nitrogen, appreciable quantities of P, K, secondary and micronutrients but low in organic load. In the incubation experiment, there was a slight increase in pH but significantly higher EC of soil receiving undiluted ALW than other treatments. The organic carbon, N and P content was higher in undiluted ALW treatment than others. The incubation period advances a significant reduction was observed irrespective of treatments. The treatments did not have considerable effect on potassium, secondary and micronutrients content of soil. In the field experiment with maize crop, the pH and EC of the soil were significantly influenced by different treatments. The organic carbon content was found to be higher in RDN through ALW (in 6 splits irrigations) + gypsum than other treatments. The available N,P, K, Ca, Mg and micronutrients showed a progressive decline with the advancement of crop growth, though marked differences were not observed due to ALW treatments except RDN through chemical fertilizers. The highest grain and stover yield of maize was recorded in RDN through ALW (in 6 splits irrigation) + gypsum. In addition to improved sensory parameters and quality of maize, the highest C: B ratio was registered in ALW treatments. In another experiment with banana crop RDN through ALW + gypsum had a pronounced effect on banana yield compared to other treatments. ALW application had no harmful effect on chemical properties of soil at harvest stage of crop. The highest C: B ratio was registered in anthropogenic liquid waste treatments. In pot experiment with radish crop, the highest EC value was recorded in 3:1 dilution (ALW: Water) applied in 2 splits compared to control but no significant difference was observed with respect to other nutrients. The highest available nutrients N, P, K, Ca, Mg content in soil at harvest stage was registered in 3:1 (ALW: Water) applied in 2 splits. Highest number of leaves, plant height , major nutrients content in leaves and root , root yield and root diameter were observed in 3: 1 (ALW: Water) applied in 2 splits compared to RDF and control. The biosand filtered anthropogenic liquid waste and the produce obtained from experiments were found to be free from Escherichia coli and Leptospira interogans. | en_US |
