Abstract:

Traditional agricultural practices often result in gaseous losses of nitrous oxide (N2O), ammonia (NH3), and carbon dioxide (CO2), representing a net loss of nutrients from agricultural soils, which negatively impacts crop yield and requires farmers to increase nutrient inputs. By adopting best management practices (BMPs; i.e., no-tillage, cover crops, sub-surface manure application, and proper manure application timing), there is great potential to reduce these losses. Because N2O and CO2 are also greenhouse gases (GHGs), climate change mitigation via BMP adoption and emissions reductions wou

Abstract:

Nitrogen (N) is one of the most essential mineral nutrients often limiting the productive capacity of terrestrial ecosystems. This nutrient is available in different chemical forms in soil which are mostly transformed from one to another through microbially mediated processes. However, the growth and activity of these microbes are often constrained by the availability of phosphorus (P) which is required for the synthesis of their genetic and cellular components, metabolism and energy transfer. Little is known about how P availability affects microbial processes responsible for N transformation

Abstract:

Eutrophication and cyanobacteria blooms are a growing problem in Missisquoi Bay of Lake Champlain in southern Quebec, and these are largely attributed to non-point source phosphorus and nitrogen (N) pollution from agricultural land in the surrounding watersheds. Residual soil N left after crop harvest contains soluble and particulate forms of N that are at risk of being transported from tile drained agricultural fields to waterways. This study aimed to find the sources of soluble N (mainly nitrate; NO3-N) and particulate organic N (PON) that are susceptible to loss, and the transport pathways

Abstract:

This thesis investigated the effect of irrigation and rainfall on nitrogen (N) cycling and fertiliser efficiency in subtropical pastures. Data gathered from field trials suggested that large rainfall events play a significant role in soil microbial processes and N losses, but by using irrigation to prevent the excessive drying of the soil profile, N losses can be reduced and pasture yield increased. Field data was then used to simulate field management scenarios in the biogeochemical model, LandscapeDNDC and seasonal irrigation and fertiliser recommendations were able to be made to maximise pr

Abstract:

Previous research shows that dissolved P losses in runoff are well related to soil test P (STP), thus, various P loss prediction models incorporate the use of a STP vs. runoff DRP relationship. However, the relationship between STP and runoff DRP will vary based on soil type due to differences in soil properties. The purposes of the first two studies were to (i) investigate the effect of soil mineralogy on P sorption behavior and dissolved P in runoff and (ii) determine if any simple soil test extractions could indirectly take into account this effect of mineralogy.

The annual soil loss from entire study area was 0.25 t/ha/year whilst these figures from commercial properties and hobby farms were 0.29 t/ha/year and 0.21 t/ha/year, respectively.

In the pastures, a cow urine patch can typically contain up to 1000 kg N ha-1.

Abstract:

This thesis summarizes the efforts of two years of field investigation and water quality data analysis. With a focus on construction sites, background monitoring was carried out at two sites and data from a third, active site was also included for analysis. The water quality data was used to estimate event-based sediment yield from each location, and continuously-collected rainfall, water level and turbidity data was used to calibrate an event-based hydrologic model (SEDCAD). Based on the results of this research and the outputs of the calibrated model, an event-based sediment yield equatio

Abstract:

博士<br>國立臺灣大學<br>土木工程學研究所<br>100<br>Landslides generate enormous volumes of sediment in mountainous watersheds; however, quantifying the downstream transport of landslide-derived sediment remains a challenge. This study estimated landslide volumes for the Shihmen Reservoir watershed in Taiwan, for six different time periods, using empirical landslide frequency-area and volume-area relationships. The percentage of total landslide volume reaching streams was estimated using empirical landslide runout models. Fluvial transport of landslide sediment to the reservoir was simulated using the Hydrolog
