National Organic Program Petition
resulting in oxidation and aggressive agitation of the product, thereby reducing the particle size of the oxidized lignite granules, as well as dissolving the humic acid derivative fractions that are soluble under acidic conditions. The final product has no detectable traces of hydrogen peroxide, but rather contains only oxidized lignite (in
Use of biochar and oxidized lignite for reconstructing ...
Oxidized lignite is readily available, marketed for its high humic acid contents, and sold under various brand names (Hoffman 1993; Giannouli et al. 2009). The biochar (mesh size<1 mm, bulk density=269 kg m −3 ) was supplied by Basques Hardwood Biochar, Luceville, QC.
Oxidized Lignites and Extracts from Oxidized Lignites in ...
crops to applications of oxidized lignite is less abundant. More work has been done using humic acid derivatives from oxidized lignite or peat than by using raw lignites. Because of this, the literature reviewed on the effect of these substances on plants and soils will come from all of these areas.
Mesa Verde Humates | 100% Genuine New Mexico Humates
Naturally-occuring, unaltered oxidized lignite, pulverized particle size - 85% less than 50 mesh. Adds organic material containing humic acids to your soil to enhance uptake of nutrients and stimulate soil life.
Oxidized Lignite In India - gobeyondmba.nl
Naturally-occurring, unaltered oxidized lignite is pulverized to a particle size 90% less than 30 mesh. This powder is an organic material which is added to your soil to enhance uptake of nutrients, increase microbial activity and stimulate soil life, and can be used as a supplemental source of trace elements.
Use of biochar and oxidized lignite for reconstructing ...
Aug 03, 2015 · We studied the effects of amending clay, loam, and sand subsoil substrates with stone biochar pyrolized at 800°C, oxidized lignite (humalite), or labile organic mix (sawdust, wheat straw, and alfalfa; LOM) on soil organic carbon (C), microbial biomass, dry aggregated size distribution and penetration resistance in greenhouse.
Hydrogen peroxide oxidation of humic acids and lignite ...
Oct 15, 2014 · The H 2 O 2 oxidation of lignite was very selective for producing malonic acid and succinic acid in high yields and the oxidation degradation method appears to be a suitable new way for utilizing South Moravian lignite. For production of malonic acid and succinic acid, the results indicated that the appropriate condition especially was at 50 °C for 4 h and 40 °C for 4 h, respectively.
Lignite - Wikipedia
Characteristics. The energy content of lignite consumed in the United States averages 15 MJ/kg (13 million BTU/ton), on the as-received basis (i.e., containing both inherent moisture and mineral matter). The energy content of lignite consumed in Victoria, Australia, averages 8.4 MJ/kg (7.3 million BTU/ton).
Leonardite - Wikipedia
Leonardite is a soft waxy, black or brown, shiny, vitreous mineraloid that is easily soluble in alkaline solutions. It is an oxidation product of lignite, associated with near-surface mining. It is a rich source of humic acid (up to 90%) and is used as a soil conditioner, as a stabilizer for ion-exchange resins in water treatment, in the remediation of polluted environments and as a drilling ...
Use of Biochar and Oxidized Lignite for Reconstructing a ...
Topsoil (TS) shortage often limits the successful reclamation of older mined sites. We evaluated the effectiveness of one-time application of biochar or oxidized lignite (humalite) alone or in combination with a mix of conventional organic materials to reconstruct functioning TS using subsoil (SS) as a substrate. Biochar or humalite carbon (C) represented a stable form of C, whereas C from a ...
Nitric Acid Oxidation for Improvement of a Chinese Lignite ...
Jul 21, 2016 · The results showed that total HA content was increased by HNO 3 oxidation, thus consequently increasing its cation exchange capacity and moderate humification. Besides, HAs extracted from oxidized lignite were richer in oxygen-containing functional groups with smaller molecular size than natural lignite.
LOW TEMPERATURE OXIDATION OF TURKISH AŞKALE LIGNITE ...
oxidation extent by thermal treatment has been not studied in detail. In light of all this literature, we performed both qualitative and quantitative analyses of oxygen functional groups under oxidation conditions varying with particle size at large temperature intervals [17]. Aşkale lignite was
