“…Furthermore, Razzaghi et al (2020) demonstrated that biochar application changed the soil pore size and distribution, and altered the residence time, N percolation mode and flow path of soil water. Simultaneously, biochar particles can provide a suitable environment for the growth of microorganisms (Haider et al 2021), and these microorganisms transform organic N into mineral N that vegetables can adsorb effectively, resulting in inhibiting N leaching loss (Warnock et al 2007). Therefore, biochar amendment may indirectly or directly affect NO 3 --N leaching via its interaction with nutrients and functional properties, including large surface area, highly porous structure, and strong ion exchange capacity, etc.…”

Maintaining nitrogen (N) balance and inhibiting N leaching loss in the soil-crop system is crucial to maintaining yield and reducing the environmental pollution. This study investigated the effects of soil NO3−-N content and accumulation, eggplant yield, N leaching and balance response to biochar addition, including regular fertilisation and irrigation (W + F), biochar addition with regular fertilisation and irrigation (W + F + B), and biochar addition with 20% fertilisation and irrigation reduction (0.8W + 0.8F + B) treatments. Compared with W + F, W + F + B and 0.8W + 0.8F + B increased soil NO3−-N content in 0–40 cm and soil NO3−-N accumulation in 0–20 cm, and raised harvest index, N surplus and balance. Simultaneously, 0.8W + 0.8F + B compared to W + F enhanced N use efficiency and N partial factor productivity, conversely, it decreased N dry matter production efficiency, N surplus and balance. Stepwise regression analysis demonstrated that the effect of NO3−-N leaching lasted in 60 cm under biochar addition in the first year, and lasted in 20 cm without biochar application in the next year. Altogether, biochar addition with 20% fertilisation and irrigation reduction is the most suitable management strategy to decrease N surplus and leaching, and maintain eggplant N uptake in a two-year cycle system on greenhouse vegetables in Mollisols.

“…Feedstocks were properly pyrolyzed using stainless-steel furnace, with 550°C pyrolysis temperature, and having a 2 hours retention time. The physico-chemical properties of biochars were determined following Haider et al (2021a). The pH and EC of the biochars were measured using pH and EC meters respectively, after shaking for 30 minutes in water having water and biochar ratio10:1 (Dume et al 2015).…”

“…Contamination of Cd signi cantly hampers the nutrients uptake, inhibits the carbon dioxide xation, affects stomatal conductance, minimizes the chlorophyll contents and photosynthetic activity that affects the overall plant productivity (Gallego et al 2012;Haider et al 2021a). Moreover, the generation and over-synthesis of reactive oxygen species (ROS) due to Cd toxicity leads to damage of plant cell membranes and the degradation of cell organelles and biomolecules (Haider et al 2021b).…”

The synergistic effects of biochar and microorganisms on the adsorption of Cd and on cereal plant physiology remained unclear. Therefore, this experiment was performed to evaluate the combined effects of biochar pyrolyzed from (maize-straw (BC1), cow-manure (BC2), and poultry-manure (BC3), and microorganisms including (T. harzianum L. and B. subtilis L.), to evaluate, how incorporation of biochar positively influences microorganisms growth and nutrients uptake in plant, and how it mitigates under various Cd-stress levels (0, 10, and 30ppm). Cd2 (30 ppm) had the highest reduction in the intercellular CO2, SPAD value, transpiration rate, water use efficiency, stomatal conductance, and photosynthesis rate, which were 22.36, 34.50, 40.45, 20.66, 29.07, and 22.41% respectively lower than control Cd0 (0 ppm). Sole application BC, resulted in enhanced intercellular CO2, SPAD value, transpiration rate, water use efficiency, stomatal conductance, and photosynthesis rate were recorded in BC2, which were 7.27, 20.54, 23.80, 5.96, 13.37, and 13.50% respectively greater as compared to control and decreased the Cd-concentration in root and shoot of maize by 34.07 and 32.53%, respectively as compared to control. Similarly, among sole microorganism’s inoculation, minimized the Cd-concentration in shoot, root, and soil by 23.77, 20.15, and 10.35% respectively than control. These results suggested that integrated application of cow manure biochar BC2 and inoculation of microorganisms MI3 as soil amendments had synergistic effects in improving the adsorption of nutrients and decreasing the Cd-uptake in maize, and enhancing the physiology of plant grown in Cd-polluted soils as opposed to using either biochar or inoculating microorganisms alone.

“…Cadmium (Cd) is a very toxic trace element found in soil. It has been identified as a carcinogenic element and poses severe threats to human health ( Haider et al, 2021 ). The primary sources of Cd contamination of croplands are anthropogenic activities, including fertilization, mining, and sewage sludge application which require additional study to alleviate Cd pollution and assure food security for the ever-growing global population ( Wu et al, 2015 ).…”
