This study was conducted to determine how irrigation alters the effects of biochar on soil health parameters in a coarse texture soil for two consecutive growing seasons. Surface soil (0–15 cm) samples from a split-plot randomized block design (main plots, unirrigated and irrigated; subplots, 0 and 11.2 Mg ha − 1 biochar) taken after soybean ( Glycine max ) harvest in 2022 and 2023 were analyzed for electrical conductivity, pH...

The limited shear capacity and brittle failure of conventional pultruded glass fibre-reinforced polymer (GFRP) rock bolts continue to restrict their application, despite advantages such as corrosion resistance and cuttability. To address this, our earlier study (Paper 1) developed braidtrusion-manufactured prototypes of GFRP rock bolts infused with graphene–epoxy matrices and identified two optimised designs, RE6 (22 mm) and R...
