Agricultural soils in the southeastern U.S. Coastal Plain region have meager soil fertility characteristics because of their sandy textures, acidic pH values, kaolinitic clays, low cation exchange capacities, and diminutive organic carbon contents. We hypothesized that biochar additions will help ameliorate some these problems. The study objectives were to determine impact pecan shell-based on water leachate chemistry for a Norfolk loamy sand (fine-loamy, kaolinitic, thermic typic...
Summary The roles of functional foods on human health have been realised by more and researchers, food producers consumers. Functional ingredients from both plant animal sources such as dietary fibre, soy protein isolate, whey isolate omega 3 fatty acid widely used in product development. Many fruit processing by‐products grape, apple orange peels are rich bioactive phytochemicals, fibre unsaturated acids, hence potential to serve ingredients. In this review, we summarise recent advancement...
Biochar additions to soils can improve soil-water storage capability; however, there is sparse information identifying feedstocks and pyrolysis conditions that maximize this improvement. Nine biochars were pyrolyzed from five at two temperatures, their physical chemical properties characterized. Biochars mixed 2% wt wt−1 into a Norfolk loamy sand (Fine-loamy, kaolinitic, thermic Typic Kandiudult), Declo silt loam (Coarse-loamy, mixed, superactive, mesic xeric Haplocalcid), or Warden...
Because the southeastern US Coastal Plain has high temperatures and abundant rainfall, its sandy soils have poor physical characteristics low carbon (C) contents. To increase soil C, we added switchgrass (Panicum virgatum) nonactivated recalcitrant pecan biochar. Biochar was developed by pyrolyzing ground shells at 700 °C. had 88% 0.4% N (C:N ratio, 220:1); 58% of C resided in polymerized aromatic ring structures. treatments were 0, 5, 10, or 20 g kg−1 soil, which Ap horizon a Norfolk loamy...
The use of biochar has received growing attention because its ability to improve the physicochemical properties highly weathered Ultisols and Oxisols, yet very little research focused on effects in Aridisols. We investigated effect low or high temperature (250 500°C) pyrolyzed switchgrass () two In a pot study, was added at 2% w/w Declo loam (Xeric Haplocalcids) Warden fine sandy Haplocambids) incubated 15% moisture content (by weight) for 127 d; control (no biochar) also included. Soils...
Excessive Cu concentrations in water systems can negatively affect biological systems. Because form strong associations with organic functional groups, we examined the ability of biochar (an O-C-enriched bioenergy by-product) to sorb from solution. In a batch experiment, KOH steam-activated pecan shell was shaken for 24 h pH 6, 7, 8, or 9 buffered solutions containing various identify effect on sorption. Afterward, all solids 24-h shaking period were air-dried and analyzed using X-ray...
Solubility, foaming capacity/stability, water holding and fat absorption capacities, emulsifying capacity/stability of a solubilized wheat protein isolate (SWPI) were compared with those commercial protein, that is, sodium caseinate (NaCAS), dried egg white (DEW), nonfat dry milk (NFDM), soy (SPI). SWPI was highly soluble at pH 6.5−8.5. Foaming capacity superior to SPI, NFDM, DEW, its stability similar the proteins. properties greatly improved in presence 0.5% (w/v) CaCl2. Water greater than...
The physical (bulk density and hardness) chemical (pH mineral content) characteristics of granular activated carbons (GACs) made from rice straw, pecan shells hulls soybean were determined. adsorption properties (iodine test, molasses test raw sugar decolourisation efficiency) these by-product-based also evaluated. A commercial decolourising carbon (Calgon CPG LF) was used as a comparison. Pecan-based had bulk densities hardness numbers higher than Calgon LF. They showed content pH similar...
Aflatoxins occur naturally in many agricultural crops causing health hazards and economic losses. Despite improved handling, processing storage, they remain a problem the peanut industry. Therefore, new ways to detoxify contaminated products are needed limit economic/health impacts add value The study was conducted (1) evaluate effectiveness of ozonation mild heat breaking down aflatoxins kernels flour, (2) quantify aflatoxin destruction compared with untreated samples. Peanut samples were...
Interest in the use of biochar from pyrolysis biomass to sequester C and improve soil productivity has increased; however, variability physical chemical characteristics raises concerns about effects on processes. Of particular concern is effect N dynamics. The dynamics was evaluated a Norfolk loamy sand with without NH4NO3. High-temperature (HT) (≥500°C) low-temperature (LT) (≤400°C) biochars peanut hull (Arachis hypogaea L.), pecan shell (Carya illinoinensis Wangenh. K. Koch), poultry...
We tested 12 organic sources as amendments for E horizon and a mixture of Bt horizons southeastern coastal loamy sand. Amendments were intended to increase carbon improve soil physical properties. included biochar, cellulose, corn (Zea mays L.) stalk, starch, cotton (Gossypium hirsutum hull, meal, manure residual, peanut (Arachis hypogaea poultry litter, soybean (Glycine max L. Merr.) plant, wheat (Triticum aestivum straw, wood shavings. added at rate ∼1% (wt wt−1) or ∼22 Mg ha−1 content 450...
