“…Laboratory column experiments with grass biochar amended-soils revealed that 20 to 40% of biochar-C leachate was sorbed by a sandy Entisol, whereas none was sorbed by a clayey Utilsol (Mukherjee and Zimmerman, 2013) suggesting influence of soil types on sorption. In another study, soil DOC was found to be sorbed to biochar-mineral complexes formed in soil aggregates (Lin et al, 2012). However, the extent to which these sorbed components may be later desorbed or are microbially available is an area for future research.…”

“…Elements were determined by ICP-MS (Perkin Elmer, USA, NexION 300D with Universal cell technology). Quantification and characterization of organic compounds were carried out by liquid chromatography with organic carbon detection (LC-OCD) using the same equipment and procedure as described in Lin et al (2011Lin et al ( , 2012. In the present study, a Toyopearl TSK HW50S column (Tosoh, USA) was used with a phosphate buffer mobile phase of pH 6.4 at a flow rate of 1.1 mL/min.…”

The production of energy and biochar from the pyrolysis of straw and other agricultural residues is a developing industry that holds the potential to reduce air pollution from in-field burning, recycle nutrients, reduce chemical fertilizer inputs, and improve soil quality. Use of biochar in agriculture is undergoing tests globally. Water-soluble organic compounds from pyrolysis residue containing humic substances, low-molecular weight acids, and neutral compounds and inorganic elements containing macro and micro nutrients have been shown to be beneficial for plant growth. In the present study, crop straw biochars were extracted into hot water and the extracts tested for their effect on growth of Chinese cabbage. The extracts were sprayed 10 times at three different dilutions throughout the growing period. The extracts were characterized for inorganic elements by ICP-MS and for organic compound type by LC-OCD and FTIR. Results showed that extracts of both wheat and maize straw biochar can significantly increase the yield, vitamin C content, and soluble protein content while decreasing the nitrate content of the cabbage at dilutions of 50 or 100 times. Water extract from biochar was found to have great potential as a liquid amendment in agricultural.

“…In addition, X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy both showed biochar particles to have higher carbon aromaticity in their core than at the surface. Lin et al (2012) examined the surface of biochar produced from chicken litter that was collected after being in the soil for one year. This work was complemented by examination of the biochar surface with XPS.…”

S. (2017). Nanoscale analyses of the surface structure and composition of biochars extracted from field trials or after co-composting using advanced analytical electron microscopy. Geoderma, Nanoscale analyses of the surface structure and composition of biochars extracted from field trials or after co-composting using advanced analytical electron microscopy Abstract Biochars have been recognized as an important material to improve soil properties. In a number of studies their beneficial properties have been found to increase with residence time in soil and during the composting process. The beneficial properties have been correlated with surface functional groups resulting from the interactions between char particles, inorganic and organic matter in the soil and soil biota. These interactions result in the formation of organo-mineral phases on the internal and external surfaces of the biochar. A paucity of information exists, particularly from longer-term field trials, on organo-mineral phases present on both the internal and external surfaces of the biochar. To characterize the structure of, and interface between, the carbon and mineral phases, we examined biochars recovered from two field trials and after composting from different countries using high resolution scanning electron microscopy (SEM), atomic resolution transmission electron microscopy (TEM) and scanning TEM (STEM), energy electron loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDS) at resolutions of 1-20 nm. The work revealed the formation of porous agglomerates of different minerals/inorganic compounds bound together with organic compounds on the surfaces of the biochar. In some cases, these agglomerates were bound together to form organo-mineral associations. The analyses also showed that the organic compounds containing both N and C functional groups and mixed valence iron oxide nanoparticles are possibly interacting with the organic compounds. The analysis also showed the formation of pores at the interface of the carbon matrix and organomineral aggregates. S. (2017).
