Land-use intensification is a key driver of biodiversity change. However, little is knownabouthowitaltersrelationshipsbetweenthediversitiesofdifferenttaxonomicgroups,which are often correlated due to shared environmental drivers and trophic interactions.Usingdata from 150 grassland sites, we examined how land-use intensification (increased fertilization, higher livestock densities, and increase...

Title of Thesis: THATCH AND SOIL PESTICIDE DEGRADATION AND MICROBIAL ACTIVITY AS INFLUENCED BY TURF CULTIVATION PRACTICES Yusong Mu, Master of Science, 2009 Thesis Directed By: Mark J. Carroll, Ph.D. Associate Professor Department of Plant Science and Landscape Architecture Pesticide degradation in turf is complicated by presence of an organic matter enriched layer called thatch. It is not well...

In this paper we analyze a speci c problem within the context of recovering the geometric shape of an unknown surface frommultiple noisy shading patterns generated by consecutive parallel illuminations by di erent light-sources. Shading-based single-view shape recovery in computer vision often leads to vector elds (i.e. estimated surface normals) which have to be integrated for calculations of ...

There is a need for systems which can autonomously perform coverage tasks on large outdoor areas. Unfortunately, the state-of-theart is to use GPS based localization, which is not suitable for precise operations near trees and other obstructions. In this paper we present a robotic platform for autonomous coverage tasks. The system architecture integrates laser based localization and mapping usi...

In this paper we analyze a specific problem within the context of recovering the geometric shape of an unknown surface from multiple noisy shading patterns generated by consecutive parallel illuminations by different light-sources. Shading-based single-view shape recovery in computer vision often leads to vector fields (i.e. estimated surface normals) which have to be integrated for calculation...

The ecosystem services framework can be used as a way of balancing economic, ecological and societal drivers in land management decision-making processes. As heathland is typically linked directly to services, the aim this study was quantify trade-offs related effects five common measures (grazing, mowing, burning, choppering, sod-cutting) using quantitative data from empirical studies within n...

Urban grassy rights-of-way (ROWs) such as along transmission lines could be managed cumulatively as collections of potential grassland habitats to contribute to the conservation of grassland birds. To optimize conservation opportunities, managing urban ROWs for grassland birds may require reductions in frequent mowing and spraying and may also depend on the suitability of landscape structure wi...

Bærheim Golfpark in Norway has changed most of its operations from conventional to automated mowing. The golf course a fleet 106 robots that mow the and pick up balls at driving range. project been innovative today, we have world's largest series-connected robot system. Along way, encountered number technical practical obstacles. Today, however, can say facility works well. transition manual mo...

In this paper, we present a multi-modal dataset for obstacle detection in agriculture. The dataset comprises approximately 2 h of raw sensor data from a tractor-mounted sensor system in a grass mowing scenario in Denmark, October 2016. Sensing modalities include stereo camera, thermal camera, web camera, 360 ∘ camera, LiDAR and radar, while precise localization is available from fused IMU and G...

Haylands are the mildest option for agricultural use of drained peatlands in terms CO2 emissions. However, fluxes and their balance may depend on various conditions including frequency mowing amount phytomass removed. Based field measurements using chamber method monitoring environmental factors conducted 2018–2020 hayland fallow peatland central European Russia, a mathematical model was built....
