Direct and residual effect of sewage sludge on yield, heavy metals content and soil fertility under rice–wheat system

Fuzzy Modeling on Wheat Productivity Under Different Doses of Sludge and Sewage Effluent

“…These results are due to the high N content in the sludge and wastewater (Duarte et al, 2008). The rice crop irrigated with wastewater and fertilized with sewage sludge provided greater spike length (Latare et al, 2014). Martínez et al, (2013) found that when wheat cultivars were fertirrigation with different levels of wastewater and sludge doses provided similar behavior to that obtained in this study with better development when irrigated with wastewater.…”

Response of fodder sorghum (Sorghum bicolor (L.) to sewage sludge treatment and irrigation intervals in a dryland condition

“…For example, because of acidity, sewage sludge was generally reported to decrease soil pH (e.g. Veeresh et al, 2009;Latare et al, 2014) but application of up to 90 t ha -1 was reported not to be significantly changed soil pH (Delibacak et al, 2009). Additionally, application of stabilized municipal sewage sludge to a degraded acid mine soil for 45 days was reported to slightly increase soil pH (Mingorance et al, 2014).…”

Evaluation of Sewage-Sludge, Zinc, Boron and Sulphur Application for Increasing Productivity and quality of Mustard (Brassica juncea L.) in an Inceptisol

“…Moreover, integrated use of sludge and inorganic fertilizers improved the physical (soil structure and water-holding capacity), chemical (buffering capacity, cation exchange capacity, macro and micro nutrients availability and reduce phosphate fixation) and biological properties of soil (organic matter, soil microbial biomass and soil microorganisms) which further provide an optimum environment for higher growth and development of plants and led to higher yield of crop (Pachauri and Trivedi, 2012;Delgado et al, 2002;Chatha et al, 2002;Indoria et al, (2013). Latare and Singh, (2013) also find out the effect of conjoint application of sewage sludge and fertilizers showed a significant increase in test weight and seed and stover yield, it also supported by Latare et al, (2014).…”

“…Improvements in soil health and consequent positive responses have been reported in various crops, viz. sunflower (Morera et al, 2013), wheat (Khan et al, 2007), maize (Zoubi et al, 2008), rice-wheat (Latare and Singh, 2013;Latare et al, 2014;Latare et al, 2017). Though, the sewage sludge is very rich in organic matter and nutrients.…”
