Nutrient fluxes and soil microbial processes
… (microbial biomass C and N) were measured under broadleaves and spruce. Soil chemistry of this highly acid soil was improved, 11 years after conversion, through an increase in base saturation and the exchangeable Mg2+ pool under rowan, as well as an increase in the exchangeable Ca2+ pool under …

Vliv dominantních druhů stromů na půdní vlastnosti
… sites on the other hand more C was stored under broadleaves. A negative correlation between sequestered C and C:N ratio in leaf litter was found on post mining sites. The results suggest that different mechanisms...

Evaluation of Benzobicyclon for use in Midsouthern Rice (Oryza sativa) Systems
… controls a broad spectrum of aquatics, broadleaves, grasses, and sedges, including those currently resistant to Group 2 herbicides. This will be the first 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicide commercially available in US rice production. Since, benzobicyclon is …

Interference and control of sharppod morningglory (Ipomoea cordatotriloba dennstedt) in glyphosate-resistant cotton.
… rotation on density or control of grasses and broadleaves. However, hand-hoed and herbicide treated plots resulted in weed densities 2- to 3-fold lower than the untreated. Preemergence herbicides and/or crop rotation can reduce weed density and improve weed control, but these strategies must be …

Influence of Isoxaben Application Timing on Dissipation and Broadleaf Weed Control in Turf
… this herbicide for PRE control of selected broadleaves in turf, suspected postemergence (POST) herbicidal effects, and the influence of application timings and rates on soil residual. During seed germination in moist filter paper, isoxaben concentrations required for 50% inhibition of …

Inventorying trees in an urban landscape using small-footprint discrete return imaging lidar
… trees into different taxonomic classes (broadleaves/conifers, genera, and species). A classification accuracy of 80.5% was obtained when separating trees only into broadleaf and conifer classes, 50.0% for genera, and 51.3% for species. Using spectral metrics from high-resolution satellite …

Climate-Triggered Drought as Causes for Different Degradation Types of Natural Forests
… physiological responses of the Caspian Hyrcanian broadleaves forests to climate-triggered droughts from regional to large scales in northeast Iran. The 16-day physiological anomalies of rangelands and forests were analysed using MODIS-derived indices concerning water content deficit and greenness …

Do benefits from cover crops vary by species or mixture composition?
… of legume seed versus grasses and non-legume broadleaves. We suggest that farmers carefully assess their goals for cover cropping when considering species choice for mixtures, and to adjust seeding rates according to their goals, i.e. increase seeding rates for legumes if nitrogen fixation is …

Forests of the future: ecosystem services in a forest landscape facing significant changes
The natural environment provides a range of benefits to people via ecosystem services. Different types of land management deliver different combinations and amounts of ecosystem services. Traditionally, many landscapes were managed to maximise the delivery of just a few benefits, such as food or …
