“…Our results demonstrated that IPNS treatments, especially biochar (PMB) and compost (OF)-based IPNS, significantly elevated MBC in both soils and MBN in charland soil. This is consistent with other research (Zhang et al, 2014b;Chaudhry et al, 2016;Liu et al, 2021). MBC and MBN increased by 8.8-50% and 20-180%, respectively, which was comparable with the recent work by Al-Suhaibani et al ( 2020) who observed 20.0-47.5% and 32.2-65.2% increases in MBC and MBN, respectively, as a result of IPNS treatments.…”

Soil acidification and charland formation through alluvial sand deposition are emerging threats to food security in Bangladesh in that they endanger crop production in about 35% of its territory. The integrated plant nutrient system (IPNS) is a globally accepted nutrient management approach designed to revive the damaged soils’ fertility level. Total organic carbon (TOC) in soil is a composite index of soil quality that has consequences for agricultural productivity and natural soil ecosystems. This study assesses the impacts of using biochar, compost, poultry litter, and vermicompost-based IPNS approaches on labile and TOC pools, TOC stocks, lability and management indices, and microbial populations under different cropping patterns after 2 years in acidic and charland soils. The application of IPNS treatments increased microbial biomass carbon (MBC) by 9.1–50.0% in acidic soil and 8.8–41.2% in charland soil compared to the untreated soil, with the largest increase in poultry manure biochar (PMB). Microbial biomass nitrogen (MBN) rose from 20 to 180% in charland soil compared to the control, although no effect was observed in acidic soil. Basal respiration (BR) rose by 43–429% in acidic soil and 16–189% in charland soil compared to the control, exhibiting the highest value in PMB. IPNS treatments significantly improved SOC and POC but did not affect POXc and bulk density in both soils. The PMB and organic fertilizer (OF, compost)-based IPNS wielded the greatest influence on the lability index of MBC in acidic soils and the management index of MBC in both soils. This is despite the fact that IPNS did not affect the lability and management indices of active carbon (AC). IPNS treatments increased the stocks of SOC and MBC in both the soils and POC stock in acidic soil. IPNS treatments significantly boosted the bacterial and fungal populations in both soils, despite having no effect on phosphorus-solubilizing bacteria (PSB). Thus, PMB and OF (compost)-based IPNS may be a better nutrient management practice in degraded acidic and charland soils. This is especially the case in terms of soil quality improvement, soil carbon sequestration, and microbial enrichment.

“…The increase in plant growth parameters, including plant height and fresh biomass weight, can also be explained by the beneficial properties of biochar. Biochar amendments can increase soil nutrient levels, such as nitrogen (N), phosphorus (P), and potassium (K), which are essential for plant growth. , This can improve soil fertility and a more favorable plant growing environment. Additionally, the porous structure of biochar can improve soil water holding capacity and aeration, which can benefit plant growth and development. − …”

Evaluating the Efficacy of Activated Carbon in Minimizing the Risk of Heavy Metals Contamination in Spinach for Safe Consumption

Toxicity induced by heavy metals is a major concern in agriculture as it decreases crops' growth and yield and leads to the deterioration of food quality. Recently, activated carbon has been identified as a possible solution. It can potentially improve crop nutrition and immobilize heavy metals in soil. That is why a glasshouse trial was conducted to investigate the effects of sugarcane bagasse-derived biochar on spinach growth and the availability of cadmium (Cd) and chromium (Cr) in artificially contaminated soil. The soil was placed in pots and contaminated with Cd and Cr at a rate of 10 mg kg −1 . Biochar was added to the soil at concentrations of 0 (control), 0 (contaminated control), 100, 150, and 200 g, and 10-day-old nursery spinach plants were transplanted to the pots. The results showed that applying 200 g of biochar significantly increased shoot weight (235 g), soil pH, electrical conductivity, and organic matter. The highest levels of Cd (27.71 mg kg −1 ) and Cr (20.44 mg kg −1 ) were observed in the contaminated control pots, while the lowest levels of Cd (16.80 mg kg −1 ) and Cr (9.80 mg kg −1 ) were found in pots treated with 200 g of biochar (2%). Similarly, the highest levels of Cd (35.80 mg kg −1 ) and Cr (40.24 mg kg −1 ) in the roots were found in the contaminated control pots, while the lowest levels of Cd (19.26 mg kg −1 ) and Cr (21.34 mg kg −1 ) were observed in pots treated with 200 g of biochar. Biochar application at a rate of 2% can immobilize Cd and Cr in the soil and improve chlorophyll contents, carotenoids, photosynthetic rate, transpiration rate, and stomatal conductance in spinach in Cd-and Cr-contaminated soils. Further long-term field studies will be necessary to determine the feasibility of applying biochar as an organic amendment for enhancing spinach growth and reducing Cd and Cr bioavailability in contaminated soil.
