Nachhaltige Landbewirtschaftung impliziert ausgeglichene Pflanzennährstoffflüsse ohne die Abhängigkeit von Düngern aus nicht erneuerbaren Quellen. Stickstoff, Phosphor und Kalium aus der menschlichen Nahrung werden in Mitteleuropa im Allgemeinen in Schwemmkanalisationen gesammelt und dabei mit Schadstoffen vermengt. Neuartige stoffstromtrennende Sanitärsysteme ermöglichen die Bereitstellung von Humanurin und Fäkalien zur Verwendung als Düngemittel.

Resumen

The improvement of water quality in the streams of the Glenelg Hopkins catchment is a priority of the Glenelg Hopkins regional strategy. A major source of water pollution in the region is linked to agricultural activities as high nutrient levels from runoff have the potential to increase the incidence of blue-green algae in the waterways. Land use change, reduced rainfall, more frequent extreme rainfall events and higher temperatures associated with climate change are likely to exacerbate this trend.

Resumen

Low fertiliser recoveries are often found for temperate coniferous forests and appear to be associated with the 'locking-up' of residual fertiliser N in stable organic forms. This phenomenon may well be caused by strong microbial immobilisation, out competing uptake by tree roots. This thesis investigates root/microbe competition for fertiliser-derived N (FDN) in microcosms of coniferous forest soil (supporting Sitka spruce seedlings) as well as in re-seeded blanket peat (supporting a mixed grass pasture). Combinations of selective microbial inhibitors, both with and without either 15N-labelle

Resumen

A field trial was established of a mixed grass sward grown on three types of golf green construction. These consisted of a topsoil, a sand, peat and soil mixture, and a pure sand. Experimental treatments applied were three levels of irrigation, five of nitrogen fertiliser and two of phosphate. The trial was maintained as a golf green, and artificial wear was applied. Soil moisture deficit predictions by the Meteorological Office conformed with measurements from the soil construction, but the sand-based construction types showed higher deficits. The overall rate of evapotranspiration was around

Resumen

In Mediterranean-type climates, topsoil frequently dries out during spring. Problems associated with reduced nutrient (P, K) availability in dry topsoil may be overcome by placing fertilisers deeper in the soil, where the soil is more likely to remain moist for longer periods as opposed to conventional fertiliser placement. Deep-P placement has resulted in significant yield improvements for lupin crops in Mediterranean environments because lupin crops generally require soil P supply during spring (throughout the flowering stage); in contrast, wheat yields have seldom improved with deep P place

Resumen

Cadmium (Cd) is absorbed through the lungs and the digestive tract; however, for most human non-smokers, the major route of Cd entry into the body is by ingestion. Perhaps 5% of ingested Cd is absorbed and once absorbed, Cd accumulates mostly in the liver and kidneys, where it can cause a variety of health problems. This applies equally to grazing stock. The major entry point of Cd into the food chain is therefore uptakes of traces of Cd by crop plants. This thesis focuses on Cd in vegetables.

The number of biogas plants in Germany is increasing from 3,711 in 2007 to 8,075 in 2016. In these biogas plants, it occurred more than 50 Mt digestate. Therefore, several investigations are started to use digestate as organic fertiliser mostly for field crop cultivation. Experiment with tomatoes was carried out were digestate was used as a supplement to the growing media in an amount of 5%, 15%, and 25%, compared with a treatment of mineral fertiliser and lupine wholemeal. The tomato yield was highest in the treatment with mineral fertilisation, the yield with 25% digestate was only a little

Resumen

Low input grassland systems depend on cheap fertiliser sources, such as clover or animal manures, to maintain sward productivity. Clover is a poor competitor for phosphate (P2O5) and potash (K2O), a mixed sward will therefore require adequate inputs of these nutrients. Nitrogen (N) leads to the suppression of clover. Recycling of cattle slurry would be followed by small N and P2O5 but large K2O effects. The K2O and P2O5 would be expected to have a beneficial effect on the clover while the N would be detrimental.

Resumen

Single superphosphate is derived from chemically treating rock phosphate into relative proportions of monobasic, dibasic and tribasic calcium phosphate to produce a commonly used source of phosphorus fertiliser for pasture systems. The leaching of phosphorus on susceptible soil types contributes to eutrophication and environmental damage. By modifying the chemistry of single superphosphate to match a soils phosphorus binding index and rainfall conditions, pasture dry matter yield can be maintained and leaching of phosphorus significantly reduced.

Fluctuations in the availability of infrastructure influence levels of risk in the supply networks.

Soil organic matter is important as storage for carbon and nutrients, supporting soil structure, and as a filter for pollutants entering the soil ecosystem. The recovery of soil organic matter in depleted soils can take decades, or even hundreds of years. It has been assumed that in non-eroding pasture, soil carbon levels either increase or not change over time. However, some recent studies have suggested that fertiliser addition to pasture soils may contribute to decreases in soil carbon content. My hypotheses were: 1.

Such an increase in true stem NRE might be achieved through manipulation of key N assimilation enzymes.

Resumen

Mineral nitrogen (N) fertiliser inputs are essential for achieving high crop yields in agricultural production systems and can help to drive farm profitability. However, when N fertiliser is applied to soil it can be lost to the environment and have negative consequences. Such losses include nitrous oxide (N2O) emissions, ammonia (NH3) emissions and nitrate (NO3-) leaching to waterways. This loss of N fertiliser also represents a substantial economic loss of N from the farm. The dominant N fertiliser source used on arable farms in Ireland is calcium ammonium nitrate (CAN) which, in environment

The production of agricultural and horticultural products requires the use of nitrogenous fertiliser that can cause pollution of surface and ground water and has a large carbon footprint as it is mainly produced from fossil fuels. The overall objective of this research project was to investigate fast pyrolysis and in-situ nitrogenolysis of biomass and biogenic residues as an alternative route to produce a sustainable solid slow release fertiliser mitigating the above stated problems. A variety of biomasses and biogenic residues were characterized by proximate analysis, ultimate analysis, therm

Resumen

This study investigated the effect of fertiliser application on methane oxidation and nitrous oxide emissions. During this study a combination of <sup>13</sup>C-CH<sub>4</sub> and <sup>15</sup>N stable isotope techniques were applied to laboratory soil incubations and traditional gas flux methodologies were applied to culture incubations. It was found that fertiliser application rate and soil pH were major influences on both methane oxidation and nitrous oxide emissions from an arable soil. Profiles of the main nitrous oxide producing processes were obtained, and it was shown that nitrificatio

Resumen

This study investigates the influence of politics on the budgeting process within the fertiliser manufacturing industry in Indonesia. Prior budgeting studies have focused on one of the following three theoretical frameworks - economic, psychological, and social. This study expands the research corpus by assessing the effect of politics on the budgeting process. The objectives of this study arc: (a) to investigate the effect of politics in the relationship between managerial roles and budgeting process – budgetary participation, budgetary communication, and budgetary control including budgetary
