Abstract Amidst intensifying global agricultural water demand, optimizing management practices and understanding the role of soil amendments, particularly biochar (BC), in modulating dynamics are critical. Here, we review potential impacts BC on dynamics, elucidate mechanistic underpinnings, identify critical research gaps prospective avenues. In general, modifies structure, hydraulic properties, surface albedo, heat fluxes, which influence storage, energy balance, irrigation paradigms....
The role of biochar as a soil amendment on the adsorption-desorption and transport tylosin, macrolide class veterinary antibiotic, is little known. In this study, batch column experiments were conducted to investigate adsorption kinetics tylosin in forest agricultural corn field soils amended with hardwood softwood biochars. Tylosin was rapid at initial stages, followed by slow continued adsorption. Amounts increased rate from 1 10%. For biochar, 10 18% higher than that when using biochar....
High soil moisture due to frequent excessive precipitation can lead reductions in maize grain yields and increased nitrogen (N) loss. The traditional methods of computing N status crops are destructive time-consuming, especially waterlogged fields. Therefore, this study, we used unmanned aerial vehicle (UAV) remote sensing evaluate the under different rates conditions. experiment was performed using a split plot design with four replications, conditions as main plots sub-plots. artificial...
Humic acids (HAs) play an important role in regulating the biogeochemistry of soils and sediments. The chemical structural composition humic substances wetland especially at coastal zone, which is subjected to influence seawater intrusion, not yet fully understood. In this study, HAs from three ecosystems along a salinity gradient namely, forest swamp (FS), freshwater marsh (FM), saline (SM), Barataria basin Louisiana coast were isolated characterized using elemental analysis, 13C solid...
The importance of silicon (Si) in nutrition is currently being recognized by its beneficial effects many crops. At present, various procedures are used to extract Si and determine soil status. This study was undertaken evaluate the relationships among extractants compare inductively coupled plasma (ICP) measurement with molybdenum blue colorimetric method for possible incorporation determination into existing routine water testing procedures. Seven were evaluated on 30 Louisiana soils. These...
Core Ideas Effect of nitrogen stabilizers were evaluated on uptake and yield cotton in poultry litter fertilized soils. Nitrogen effect losses as NH 3 N 2 O from pine hardwood biochar uptake, cotton, Poultry (PL) serves a multi‐nutrient fertilizer. However, compared to inorganic fertilizers, PL requires high rate application meet crop nutrient requirements due relatively low concentration easy loss nutrients. A 4‐yr field experiment was conducted with ( Gossypium hirsutum L.) examine the...
Core Ideas Application of urea led to higher N 2 O emissions than urea–ammonium nitrate in sugarcane. Residue retention and CH 4 irrespective source. Both source residue management did not affect CO emissions. Sugarcane ( Saccharum spp.) is a major row‐crop the southern United States with high rates N‐fertilizer application unique harvest‐residue management. A 2‐yr field experiment was conducted investigate different effects (urea ammonium nitrate, UAN) managements (residue‐retain, RR,...
