Estimation of the global carbon fluxes due to agricultural management activities using a land surface model (ISAM)
Agricultural activities contribute to global greenhouse gas (GHG) emissions and climate. The worldwide hike in the food demand due to the rapidly growing population over time has intensified agricultural activities, resulting in a significant amount of GHG emissions (e.g., CO2, CH4, and N2O). …

Terracing, Land Management and Agricultural Soils in the Andagua Valley of the Southern Peruvian Andes
… and climatic changes can drastically alter agricultural land management practices, affecting the availability of agriculturally relevant nutrients in the soil. This project investigates the use, reconstruction and abandonment of agricultural terraces and the implications these conditions …

A generic protocol for an integrated land information system in humid subtropical highlands: a case study in Yunnan Province, China
This study develops a basis for a land information system for the 40 ha subtropical highland catchment of Wang Jia, Yunnan Province, China. Information, including meteorology, geology, geomorphology, biology, pedology and crop productivity, was integrated using a geomorphopedological approach and …

The quantification and characterization of soil carbon pools in biofuel agriculture.
… shift toward renewable energy resources through agricultural biofuel production provides an opportunity to study and implement sustainable land management practices that improve soil health and a deeper understanding of mechanisms involved in terrestrial carbon cycling. Agricultural land …

Potential for the restoration of lowland and wet grassland upon ex-arable land
… and reverse biodiversity losses. In England, agri-environment schemes have enabled deintensification of agricultural land management and active promotion of habitat types of conservation value within the farmed landscape. One such habitat, lowland wet grassland, is represented within …

An Improved Water-Driven Sediment Yield Model for Cold Agricultural Regions
… typically from water-driven erosion occurring in agricultural regions, is a significant source of pollution and damage to the aquatic environment. Excess sediment erosion promotes the transport of phosphorus to lakes, which can increase cyanobacterial growth, cause sedimentation that limits the …

Effect of bioenergy crops and fast growing trees on hydrology and water quality in the Little Vermilion River Watershed
… the Midwest area to become highly productive agricultural lands, but also create environmental problems like nitrate-N contamination of the water it drains. The Soil and Water Assessment Tool (SWAT) has been used to model watersheds with tile drainage, but the new tile drainage routine in …

The potential effectiveness of eco-n nitrification inhibitor in reducing nitrification rates in a range of key New Zealand dairy pasture soils: A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours
… soil types from key dairying regions of New Zealand (Northland, Waikato, Bay of Plenty, Taranaki, West Coast of the South Island and Southland) when incubated at 10°C. Incubation vessels (10 cm diameter by 15 cm height) were packed with 4 mm sieved soil from the different regions and treated …

Factors influencing agro-environmental regulatory compliance behaviour on Canterbury dairy farms
… regulations were implemented under the Resource Management Act (1991) to limit and mitigate the impacts of agricultural production, among other sectors. Compliance with environmental regulation as it pertains to effluent management on Canterbury dairy farms for the past several seasons has …

The effect of winter grazing and a nitrification inhibitor on nitrous oxide emissions and denitrification in a stony soil
… winter months in the Canterbury region of New Zealand. Such intensive grazing on wet soil increases the risk of denitrification and the production of the powerful greenhouse gas, nitrous oxide (N₂O). However, at the beginning of this research project, no information was available on …

Ecological assessments of Pseudomonas communities in pastoral soils: implications for disease suppression and sustainable production in agricultural grasslands
Grasslands are an important source of biodiversity, providing a range of essential ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are being used to support grazing livestock, with agricultural grasslands covering over 25% of the …
