Article Synopsis
- Heavy oil fly ash (HOFA), a hazardous waste from power stations, poses environmental risks and needs sustainable recycling methods, particularly as a soil amendment for sandy soils.
- This research is the first to investigate HOFA's potential as a soil conditioner, assessing its effects on nutrient and toxic element content in sandy soil and its impact on the growth of lemongrass and common sage.
- Lower doses of HOFA did not significantly alter soil properties, but the highest dose (3.6 t ha) elevated element levels and negatively affected plant growth, while common sage showed greater accumulation of elements compared to lemongrass.
Article Synopsis
- Climate change and population growth are major threats to global food security, leading to the exploration of plant growth regulators (PGRs) as solutions.
- The apocarotenoid compounds MiZax3 and MiZax5 have been found to enhance the growth of crops like potato and strawberry in Saudi Arabia under field conditions.
- These compounds proved to be effective at low concentrations, outperforming conventional treatments like humic acid, highlighting their potential for improving vegetable crop yields in challenging environments.
A microwave hot pressing machine (MHPM) was used to heat the colander to produce fixed oils from each of castor, sunflower, rapeseed, and moringa seed and compared them to those obtained using an ordinary electric hot pressing machine (EHPM). The physical properties, namely the moisture content of seed (MCs), the seed content of fixed oil (S), the yield of the main fixed oil (Y), the yield of recovered fixed oil (Y), extraction loss (EL), six Efficiency of fixed oil extraction (E), specific gravity (SG), refractive index (RI) as well as chemical properties, namely iodine number (IN), saponification value (SV), acid value (AV), and the yield of fatty acid (Y) of the four oils extracted by the MHPM and EHPM were determined. Chemical constituents of the resultant oil were identified using GC/MS after saponification and methylation processes.
