“…The synergistic application of PGPR and biochar had a highly positive effect on physiological traits, plant growth, and yield-related traits in comparison to sole application and control treatment. The improvement in plant development might be attributed to the biosynthesis of phytohormones, like IAA, which could essentially be linked to the yield and its components [ 58 ], increasing nutrients [ 48 , 59 , 60 ], the activity of 1-aminocyclopropane-1-carboxylate (ACC) deaminase, and osmolyte production [ 41 , 61 ]. Our findings showed that singular application of biochar significantly enhanced the growth, physiology, and productivity of maize compared with PGPR and non-treated control.…”

The utilization of low-quality water or slightly saline water in sodic-saline soil is a major global conundrum that severely impacts agricultural productivity and sustainability, particularly in arid and semiarid regions with limited freshwater resources. Herein, we proposed an integrated amendment strategy for sodic-saline soil using biochar and/or plant growth-promoting rhizobacteria (PGPR; Azotobacter chroococcum SARS 10 and Pseudomonas koreensis MG209738) to alleviate the adverse impacts of saline water on the growth, physiology, and productivity of maize (Zea mays L.), as well as the soil properties and nutrient uptake during two successive seasons (2018 and 2019). Our field experiments revealed that the combined application of PGPR and biochar (PGPR + biochar) significantly improved the soil ecosystem and physicochemical properties and K+, Ca2+, and Mg2+ contents but reduced the soil exchangeable sodium percentage and Na+ content. Likewise, it significantly increased the activity of soil urease (158.14 ± 2.37 and 165.51 ± 3.05 mg NH4+ g−1 dry soil d−1) and dehydrogenase (117.89 ± 1.86 and 121.44 ± 1.00 mg TPF g−1 dry soil d−1) in 2018 and 2019, respectively, upon irrigation with saline water compared with non-treated control. PGPR + biochar supplementation mitigated the hazardous impacts of saline water on maize plants grown in sodic-saline soil better than biochar or PGPR individually (PGPR + biochar > biochar > PGPR). The highest values of leaf area index, total chlorophyll, carotenoids, total soluble sugar (TSS), relative water content, K+ and K+/Na+ of maize plants corresponded to PGPR + biochar treatment. These findings could be guidelines for cultivating not only maize but other cereal crops particularly in salt-affected soil and sodic-saline soil.

“…Unagwu et al (2021) reported an increase in soil pH after application of animal (chicken, cow, and pig) manure at 15 t ha −1 compared to the control treatment. Calamai et al (2020) found a significant effect on soil pH after organic amendment application. A positive effect of animal manure in neutralising soil acidity has been reported (Han et al, 2016;Du et al, 2020;Rayne, Aula, 2020;Ferreira et al, 2022).…”

One of the main UN Millennium Development Goals is eradication of poverty and hunger through food security. Unfortunately, this goal is difficult to achieve in Nigeria due to soil degradation, low soil fertility, and other agricultural challenges. The current research on food security in Nigeria is focused on improving soil fertility using low-cost organic amendments. Thus, in 2019, the study investigated the residual effects of the repeated animal manure application on the cucumber (Cucumis sativus L.) yield, the nutrient uptake, and the soil nutrient status of a coarse-textured Ultisol in a greenhouse at the University of Nigeria, Nsukka. The experiment was conducted in a completely randomised design with four treatments: poultry manure (PM30), cow manure (CM30), and pig manure (PgM30) applied at 30 t ha −1 , and untreated control with five replicates. The experiment was performed (repeated) three times. The results showed that the soil pH increased (p < 0.05) by 33.3% for the PM30 treatment, 13% for the PgM30 treatment, and 11.1% for the CM30 treatment and decreased by −7.4% for the control treatment compared to the initial amount of the soil pH (5.4). The total nitrogen (N tot ) increased by 99.4% (CM30), 63.3% (PgM30), and 56.3% (PM30) compared to the initial N tot (4.8 g kg −1 ). The available phosphorus (P avail ) in the PM30, PgM30, and CM30 treatments increased by 1204%, 171%, and 164%, respectively, while in the control treatment, it decreased by −59.6% compared to the initial P avail (7.57 mg kg −1 ). The soil organic carbon (SOC) increased by 13.3% (CM30), 3.9% (PM30), and 3.9% (PgM30) compared to the initial SOC content (1.28%) and decreased by −18.8% in the control treatment. Cucumber growth parameters: the number of fruits, fruit weight, and biomass (fresh and dry), were significantly higher (p < 0.05) in the amended treatments compared to the control treatment. There was a significant correlation between the cucumber yield, N-uptake, P-uptake, and soil nutrients. The results of regression analysis showed that the cucumber yield was increased by 91, 61, 56.4, and 86.4 % due to SOC, N tot , N-uptake, and P-uptake, respectively. This study indicates that the repeated animal manure application has a positive residual effect on the properties of coarse-textured Ultisol and cucumber yield performance.

Abundant animal manure in livestock areas has the potential to be used as organic fertilizer which can restore soil fertility by turning it into compost and biochar. The goal of this study was to as-sess how well soil fertility and red chili yield might be increased by using biochar and poschar made from various animal wastes. In this investigation, a factorial pattern and randomized block design were used. The first factor was the biochar treatment type, which included no biochar, biochar made from cow manure, biochar made from goat manure, and biochar made from chicken manure. The second factor was the type of poschar, which included no poschar, poschar made from cow manure, poschar made from goat manure, and poschar made from chicken manure. The findings of this study suggest that using biochar in conjunction with poschar can significantly improve soil parameters such as soil water content, pH, EC, humic acid, fulvic acid, C, N, P, K, and CEC. Red chilies grow and yield more per hectare when different types of biochar and poschar are used. The use of biochar from cow manure together with poschar from chicken manure shows the best agronomic effectiveness.
