“…phosphaticum, and P. fluorescens, and treated with 50 g PG kg −1 significantly reduced soil EC. Additionally, [28] showed that the pH and EC decreased significantly (p < 0.05) with increased PG application rates. For example, PG at a rate of 10 ton ha −1 in clay soil with maize plants showed a higher reduction in EC, ranging from 26% with the recommended nitrogen fertilizer (NF) with the water treatment residual at 5 t ha −1 (WTR5) to 48% for NF+PG10 compared with the other treatments.…”

“…Smaoui-Jardak [41] suggested that PG application (20%) seems to be beneficial for increasing the productivity of tomato plants under saline soil conditions. Mahmoud et al [28] reported that the use of 10 t ha −1 of PG was optimal for achieving high productivity of maize plants grown in clay soils.…”

“…In different countries around the world, phosphogypsum is used in agriculture either as a soil amendment (calcium sulfate) or as fertilizer [25], which may be an efficient amendment to reclaim alkaline soils by improving the soil properties and the availability of different nutrients to crops (direct) or in combination with microbes to enhance the solubility of nutrients (indirect) [26]. Several investigators have suggested that synergistic application with PG and microbial inoculation increased the levels of NPK uptake and enhanced the growth of maize plants [26], enhancing the microbial biomass carbon, N concentrations, soil enzyme, and plant growth [27,28]. Therefore, the objective of this study was to investigate the application effects of different rates of PG combined with microbial inoculation on chemical and biological soil properties, plant physiology, antioxidant enzymes, the contents of macro-and micronutrients, and the yield of maize plants grown in salt-affected soil.…”

The use of phosphogypsum (PG) and plant growth-promoting rhizobacteria (PGPR) for agricultural purposes are good options to improve soil properties and increase crop yield. The objective of this study was to investigate the effect of different rates of PG (ton ha−1; 0 (PG1), 3 (PG2), 6 (PG3), and 9 (PG4)) combined with PGPR inoculation (Azospirillum lipoferum (control, T1), A. lipoferum + Bacillus coagulans (T2), A. lipoferum + B. circulance (T3), and A. lipoferum + B. subtilis (T4)) on soil properties, plant physiology, antioxidant enzymes, nutrient uptake, and yield of maize plants (Zea mays L., cv. HSC 10) grown in salt-affected soil. Over two growing seasons, 2019 and 2020, field experiments were conducted as a split-plot design with triplicates. The results show that applying PG (9 ton ha−1) and co-inoculation (A. lipoferum + B. circulance) treatment significantly increased chlorophyll and carotenoids content, antioxidant enzymes, microbial communities, soil enzymes activity, and nutrient contents, and showed inhibitory impacts on proline content and pH, as well as EC and ESP, thus improving the productivity of maize plant compared to the control treatment. It could be concluded that PG, along with microbial inoculation, may be an important approach for ameliorating the negative impacts of salinity on maize plants.

“…WTR are mainly composed of finer mineral particles (Petterle et al, 2018) and, thus, their application in sandy soils may maintain or increase the cation exchangeable capacity and water holding capacity (Heil & Barbarick, 1989; Ibrahim et al, 2015, 2020; Mahmoud et al, 2020). Furthermore, BS can provide significant amounts of organic matter and nutrients such as phosphorus and nitrogen (Mossa et al, 2020; Pereira et al, 2020).…”

Liming and co‐application of water treatment residuals with biosolids for conditioning sandy soils

et al. 2022

Application of water treatment residuals (WTR) and biosolids (BS) might ameliorate fragile soils. However, studies integrating impacts of waste preparation methods such as liming and grinding associated with co-application approaches for soil conditioning are lacking. The present study aimed to evaluate the feasibility of agricultural use of WTR as well as their co-application with BS to ameliorate a sandy soil through assessing impacts on selected soil quality indicators and on nutrient and potentially toxic element concentration in plant tissue in addition to the biomass yield of annual crops. The following treatments were evaluated: non-amended soil (control); drying plus grinding and liming WTR; WTR co-application with BS at 3:1 ratio; and a soil amendment commercially available in Brazil. All treatments were soil incorporated in the 0.0-0.2 m layer at 30 Mg ha À1 dose (dry mass). Selected soil physical, hydraulic, and chemical parameters were determined. Furthermore, nutrients and potentially toxic elements concentration in plant tissue as well as the agronomic performance of maize and ryegrass were measured. The co-application of WTR and BS increased the soil content of P, Zn, and Cu in the 0.0-0.1 m layer. The concentration of these nutrients also was greater in ryegrass tissue and promoted the biomass yield in 51%. WTR did not increase contaminants and did not decrease the P content in soil and in plant tissue, independently of drying plus grinding and liming. Considering the conditions investigated in our study, WTR/BS co-application was environmentally safe and effective in ameliorating soil quality.
