“…The application of NG (control) did not increase soil pH, but the application of SBG significantly increased the soil pH which was mainly due to its alkaline nature and its reaction products (Haynes et al 2013;Negim et al 2010). Similarly, Prakash et al (2020) observed significant increase in postharvest soil pH with 150 to 750 kg SBG ha −1 in maize crop. Several studies have demonstrated the release of OH − as a result of ligand exchange between SO 4 2− and OH − during equilibration of soils with solutions containing SO 4 2− (Farina and Channon 1988;Sumner 1994;Zhang et al 1987).…”

“…Similarly, Anthati (2011) reported that the application of 500 kg gypsum ha −1 each at basal and flowering for groundnut significantly increased the soil EC. The application of graded levels of SBG significantly increased the EC of acidic soil after the harvest of maize (Prakash et al 2020).…”

“…The beneficial role of Fe and Zn on yield of groundnut could be attributed to its vital role in the activation of enzymes for biological processes in plants, thereby increasing growth and yield parameters (Singh and Chaudhari 1997;Gobarah et al 2006;Rahevar et al 2015). Similarly, Prakash et al (2020) reported significant increase in maize cob and stalk yield with 750 kg SBG ha −1 fertilization. Higher pod yield in Baljigapade than Pavagada can be mainly due to higher fertility status especially availability of Ca and S in former location than latter.…”

“…Gypsum sources were well powdered and passed through 2mm sieve and used in the present study. SBG has more or less equal amounts of Ca and S compared with NG, but additionally, it has 180 times higher Fe, twice that of SiO 2 and small amounts of Zn, Mn and P 2 O 5 (Prakash et al 2020). The pH of SBG and NG was moderately alkaline (8.14) and very strongly acidic (4.92), respectively.…”

“…The common utilization of slag includes cement manufacturing, concrete and road aggregates, soil fertilizer and metal stabilizing in contaminated soils (Ali and Shahram 2007;Khan et al 1994;Lopez et al 1995;Pinto et al 1995). The application of slag-based gypsum and calcium silicate slag to acid soil as an amendment increases soil pH, available P, K, Si, exchangeable Ca and Mg and Mn (Abou-Seeda 2002;Barbosa Filho et al 2004;Prakash et al 2020). Slag-based gypsum (SBG) is a synthetic gypsum produced from steel industrial waste such as LD slag by treating it with concentrated sulphuric acid and 20% lime solution, and during this treatment, all the impurities and heavy metals get leached into solution and Ca and Si remain insoluble (Ashrit et al 2015).…”

Slag-based gypsum (SBG) is a unique synthetic gypsum which is alkaline in nature, besides calcium (Ca) and sulphur (S); it contains appreciable amounts of iron (Fe), silicon (Si), phosphorus (P) and zinc (Zn). In this study, we evaluated the efficacy of SBG as a source of S, Ca and Si for groundnut in comparison with natural gypsum (NG). The effect of different levels and time of application of SBG on soil fertility and yield and quality of groundnut were also studied. Field experiments were conducted with five treatments which includes two levels of SBG (500 and 625 kg ha −1) applied as basal and basal + split and one level of NG (500 kg ha −1) applied as basal. Basal and basal + split applications of SBG significantly increased the pod and haulm yield of groundnut, pH, electrical conductivity and plant-available nutrients in post-harvest soil. However, N:S ratio, kernel and protein yield and oil content did not vary with SBG application. Applied S, Ca and Si as SBG and their uptake were positively correlated with plant-available S, Ca and Si and pod, oil and protein yield of groundnut, respectively. Basal and basal + split applications of SBG resulted in a similar effect on soil fertility and yield and quality of groundnut. Findings from this study show that SBG can be a potential alternative for NG as a source of S, Ca and Si for groundnut production. Among the treatments, basal and basal + split applications of 625 kg SBG ha −1 substantially improved the fertility of soils and yield and quality of groundnut.

Evaluation of humic fertilizers on a sand‐based creeping bentgrass putting green

et al. 2021

View full text Add to dashboard Cite

Turfgrass with sand‐based root zones, such as golf course putting greens, are highly important economically and require intense management. However, problems are often associated with sand‐based root zones, such as low nutrient retention and limited microbial activity. Soil additives may increase soil biological activity, improve nitrogen (N) cycling efficiency, and thus reduce fertilizer N inputs. A 2‐yr experiment was conducted on a sand‐based creeping bentgrass (Agrostis stolonifera L.) putting green to investigate whether humic products could increase soil biological activity and improve turfgrass quality. Treatments included humic‐coated urea (HCU; 2/3 rate and full rate), HCU + humic dispersing granules (HDG), HCU + black gypsum (BG), urea, HDG, and a nontreated control. Minimal differences were seen in microbial biomass and activity besides HCU + BG. The HCU + BG had 60% greater potentially net N mineralization relative to the HDG and the nontreated control. Overall, incorporating humic substances with N fertilizer did not increase turfgrass quality, cover, and clipping biomass compared with N fertilizer alone. However, the addition of BG to N fertilizer enhanced microbial activity (i.e., potentially net N mineralization).
