Biochar derived from bone waste (bone char) is a promising phosphorus fertiliser. However, limited nutrient availability restricts its agricultural application; therefore, different amendments have been investigated to modify nutrient release from biochar. This study evaluated the effects of pyrolysis temperature and the addition of potassium tartrate (KTar) as an in-situ catalyst on the water solubility of selected macro- and micronutrients in chicken bone waste-derived bone char. Chicken bone waste (CBW) was mixed with KTar at a 10 : 1 mass ratio and pyrolysed at 400–800 °C for 30 min. The KTar modification strongly affected nutrient...

Understanding how chelated selenium (Se) regulates plant stress tolerance is critical for optimising field applications. We investigated dose-dependent effects of foliar-applied lysine-chelated selenite (0, 15, 30, 45, and 60 g/ha selenite) on antioxidant capacity and Se distribution in wheat (Triticum aestivum L.) under field conditions. The results indicated that the optimal application dose (30 g/ha) most effectively suppressed O2– and H2O2 accumulation by 47.8% and 47.2%, respectively, and reduced MDA concentration by 74.0%. This effect was attributed to enhanced activities of superoxide...

Autotoxic stress can disturb cassava (Manihot esculenta Crantz) endogenous hormones, thus hindering plant growth and development. However, the mechanisms by which cassava responds to autotoxic stress are still unknown. Hydroxyacetone, 2,4-di-tert-butylphenol, and acetic acid, previously confirmed as the main autotoxins, were applied in this study to simulate autotoxic stress on cassava using a tissue culture approach. Three genotypes, SC205, NZ199, and XX048, were used as plant materials. The allelopathic effects varied with genotype. Under autotoxicity stress, XX048 showed stronger negative allelopathy than SC205 and NZ199, with root length...

Long-term use of conventional polyethylene mulch film (PE) causes white pollution, whereas biodegradable poly(butylene adipate-co-terephthalate) (PBAT) mulch film can serve as an alternative to PE mulch film. However, research on the effects of long-term residual PBAT mulch film on soil microbial communities and tobacco growth remains limited. In this five-year field experiment, we compared the annual PBAT mulch treatment with a single-dose PE film treatment and a non-mulching blank control (N) to explore their effects on soil microbial communities and tobacco growth. Scanning electron microscope results indicated that the surface of the PBAT mulch...
