“…Literature showed varying observations from the biochar physico-chemical properties of the present study. It was observed similar pH (8.1), but a much lower EC (0.85 dS m -1 ) and much higher CEC (65.3 Cmolc Kg -1 ) for RSB (33,34). Lower pH (6.35) but higher EC (2.44 dS m -1 ) and similar CEC (27.5 Cmolc Kg -1 ) were reported for SDB (26).…”

Biochar, a carbonized biomass, can be used as a soil amendment for improving soil fertility and productivity as well as ensuring agricultural sustainability. Biochar can be produced from different materials and at different conditions, so its quality varies greatly as a soil amendment. In this respect, the present study aimed to explore the effectiveness of 4 biochars as a soil ameliorator for securing soil health. The biochars were produced from 3 different biomasses viz., rice straw, sawdust and water hyacinth and their mixture (co-biochar at 1:1:1) at 400 ºC. The biomasses and the biochars were characterized and the results revealed that conversion of biomasses into biochars caused a significant (p<0.05) increase in almost all of the biochar properties. Among the 4 biochars, water hyacinth biochar showed higher ash content, water holding capacity, surface area and total P, K, S, Ca and Zn. So, water hyacinth biochar could be a better choice as a soil amendment than the other three biochars. However, rice straw biochar showed higher cation exchange capacity (CEC), total N and Na and conversion efficiency of C, N, P, K, Na and Zn. Whereas, the co-biochar illustrated higher yield and showed the second highest in fixed C, CEC, total S, Ca and Zn and also in conversion efficiency of C, P, S, Na, K and Ca. Finally, it can be assumed to produce a co-biochar using rice straw at a higher ratio which might have a high potential for C storage and for supplying all of the essential plant nutrients.

“…These studies reported that the content of Olsen-P increased significantly with the application of maize stalk biochar compared to the control. The concentration of Olsen-P in soil increased further with the increase in the biochar application rate because of its higher potential for unlocking P 3 .…”

Nitrogen (N) and phosphorus (P) are vital for crop growth. However, most agricultural systems have limited inherent ability to supply N and P to crops. Biochars (BCs) are strongly advocated in agrosystems and are known to improve the availability of N and P in crops through different chemical transformations. Herein, a soil-biochar incubation experiment was carried out to investigate the transformations of N and P in two different textured soils, namely clay loam and loamy sand, on mixing with rice straw biochar (RSB) and acacia wood biochar (ACB) at each level (0, 0.5, and 1.0% w/w). Ammonium N (NH4-N) decreased continuously with the increasing incubation period. The ammonium N content disappeared rapidly in both the soils incubated with biochars compared to the unamended soil. RSB increased the nitrate N (NO3–N) content significantly compared to ACB for the entire study period in both texturally divergent soils. The nitrate N content increased with the enhanced biochar addition rate in clay loam soil until 15 days after incubation; however, it was reduced for the biochar addition rate of 1% compared to 0.5% at 30 and 60 days after incubation in loamy sand soil. With ACB, the net increase in nitrate N content with the biochar addition rate of 1% remained higher than the 0.5% rate for 60 days in clay loam and 30 days in loamy sand soil. The phosphorus content remained consistently higher in both the soils amended with two types of biochars till the completion of the experiment.
