The proper preparation of the surface of concrete is an important stage in the construction and renovation of building structures. Before placing a concrete topping it is essential to determine the morphology of the concrete base surface. This paper describes a novel application of three-dimensional (3D) optical laser triangulation method for investigation of the concrete surface morphology. It...

In Central Europe, full-tree (FT) harvesting is an increasingly common harvesting method in steep terrain harvesting due to the increased use of highly economical processor tower yarders. In conventional FT harvesting, nutrient removal from harvest sites is substantially higher than in cut-to-length (CTL) harvesting due to the extraction of nutrient-rich branches and foliage. One strategy to re...

From 2018 to 2020, an experiment on effects of nitrogen top-dressing was conducted with Burley tobacco the Zagreb experimental field at Faculty Agriculture. The set up according RCBD in four replications. Nitrogen added five different variants: 1) control 100% from CAN; 2) 90% CAN + 10% microcapsules; 3) 80% 20% 4) microcapsules chitosan; and 5) chitosan. During vegetation, number leaves, lengt...

The crop will be free from the control of apical dominance and axillary buds develop into branches after topping. However, there are relatively few studies on this subject soybean. In order to further improve soybean grain yield, unbranched type high-yield variety was used as test material, effects topping at first trifoliate stage plant growth, dry matter accumulation, yield components five pl...
