“…Usually the availability of K in soil is increased with the addition of biochar irrespective of the study, although some negative impacts of biochar on the availability of K in soil have been reported ( Table 5). The addition of biochar (10 t ha −1 ) increased the Mg content in a loamy sand soil (Lusiba et al 2017).…”

“…(2) as a nutrient sink, thereby impacting the mobility and bioavailability of nutrients (Gul and Whalen 2016); and (3) as a soil conditioner, thereby altering soil properties that influence the reactions and cycling of nutrients in the soil (Lusiba et al 2017). As a source, biochar can supply nutrients such as nitrogen (N), phosphorus (P), potassium (K), and other trace elements inherently present in the original feedstock used for biochar production (Purakayastha et al 2019).…”

Biochar, an environmentally friendly soil conditioner, is produced using several thermochemical processes. It has unique characteristics like high surface area, porosity, and surface charges. This paper reviews the fertilizer value of biochar, and its effects on soil properties, and nutrient use efficiency of crops. Biochar serves as an important source of plant nutrients, especially nitrogen in biochar produced from manures and wastes at low temperature (≤ 400 °C). The phosphorus, potassium, and other nutrient contents are higher in manure/waste biochars than those in crop residues and woody biochars. The nutrient contents and pH of biochar are positively correlated with pyrolysis temperature, except for nitrogen content. Biochar improves the nutrient retention capacity of soil, which depends on porosity and surface charge of biochar. Biochar increases nitrogen retention in soil by reducing leaching and gaseous loss, and also increases phosphorus availability by decreasing the leaching process in soil. However, for potassium and other nutrients, biochar shows inconsistent (positive and negative) impacts on soil. After addition of biochar, porosity, aggregate stability, and amount of water held in soil increase and bulk density decreases. Mostly, biochar increases soil pH and, thus, influences nutrient availability for plants. Biochar also alters soil biological properties by increasing microbial populations, enzyme activity, soil respiration, and microbial biomass. Finally, nutrient use efficiency and nutrient uptake improve with the application of biochar to soil. Thus, biochar can be a potential nutrient reservoir for plants and a good amendment to improve soil properties.

Assessment of Zeolite, Biochar, and Their Combination for Stabilization of Multimetal-Contaminated Soil

In this study, the natural zeolite and rice husk biochar were mixed as a combination amendment for metal immobilization in a Cd, Pb, As, and W co-contaminated soil. A 90 day incubation study was conducted to investigate the effects of amendments on toxic metal in soil. Zeolite, biochar, and their combination application increased the soil pH and cation exchange capacity. A combination of amendments decreased the bioavailability of Cd, Pb, As, and W. Besides, the potential drawback of biochar application on As and W release was overcome by the combination agent. Zeolite, biochar, and combination treatment decreased total bioavailability toxicity from 335.5 to 182.9, 250.5, and 143.4, respectively, which means that combination was an optimum amendment for soil remediation. The results of the Community Bureau of Reference sequential extraction and scanning electron microscopy–energy-dispersive spectrometry images confirmed the Cd and Pb adsorption onto biochar. However, As and W immobilization was dominantly controlled by zeolite. It appears that the combination of amendments is an efficient amendment to remediate Cd, Pb, As, and W co-contamination in soil, although the combination of amendments has a lower stabilization rate for W than for zeolite.

“…Recently, a few references reported significant effects of co-application of biochar and inorganic fertilizer on soil properties and crop yield [23,[25][26][27][28][29][30]. Co-application of biochars and chemical fertilizer in soil improved wheat productivity and nitrogen uptake, where the increment was the highest in manure biochars, and it is recommended to use manure biochar alone or in combination with chemical fertilizer for immediate crop benefits [30].…”

“…The interaction between rice husk biochar and inorganic nitrogen fertilizer significantly enhanced rice yield and yield components compared to the control, while enhancing soil nutrient availability and minimizing nitrate leaching [29]. Lusiba et al reported a significant interaction between eucalyptus biochar and phosphorous fertilizer on the soil physical and chemical properties and chickpea yield [28]. Liu et al also found that the addition of biochar and phosphorous fertilizer showed more positive effects on the promotion of growth and nutrient uptake of L. multiflorum [23].…”

Although sulfur is an indispensable element for plants, its availability to plants in the presence of biochar is unclear. The effects of dairy manure biochar at the rate of 0, 0.5, 1, 2, and 5% on plant physiological characteristics, soil properties and sulfur phytoavailability in corn (Zea mays L.)-Calcids soil system were investigated using pot experiments with sulfate amendment at low, moderate and high level (0, 50 and 100 mg S kg -1 soil). It was found that the plant height, fresh and dry weight, and chlorophyll content were significantly improved with the biochar addition rate increasing from 0 to 2% while largely decreased with the rate increasing from 2% to 5%. The moderate level of sulfate amendment favored the corn biomass and chlorophyll content. The pH values of soil were significantly increased with increasing biochar addition rate, reaching about 8.50 at the rate of 5%. The catalase, urease and sucrase activity in soil increased significantly with the biochar addition from 0 to 2% but largely decreased with the rate increasing from 2% to 5%. Too high pH values due to 5% biochar addition resulted in the inhibitory effects on plant growth and microorganism activity in soil. Biochar addition at low rates (<2%) and sulfate amendment at high level improved sulfur content in leaves and roots. The decreases of inorganic sulfur and total sulfur contents in soil with biochar addition rates significantly responded to the accumulation of sulfur in leaves and roots. The results show that co-application of biochar and sulfate with proper amount could improve the growth and sulfur phytoavailability of plant in calcareous soil.
