The effects of vegetation size and architecture, in combination with elevation effects, on the amounts of atmospheric inputs of both nutrient and pollutant substances were studied by means of collecting precipitation both above and below tree and heather canopies. Use was made of 'filter' type gauges, designed to enhance interception deposition, in order to identify the main ionic substances associated with this deposition type. Results illustrate how effects of tree size and shape, as well as elevation, are tempered by local topographic and climatic factors. The total leaf area of the canopy

Lake Illawarra is a shallow barrier lagoon, located on the south-eastern coast of Australia.

Management of macroalgae in Lake Illawarra is a major issue; excessive blooms of macroalgae, resulting in odours, access problems and community concern over Lake health, have led to many management strategies, including direct harvesting of algal biomass.

In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. The interest to improve resource recovery of horse manure increases due various incentives for renewable vehicle fuels, legal requirements on management of manure, and environmental impact from current horse manure management. This thesis aims at describing horse manure management in a life cycle perspective.

Review of the literature suggested possible deficiencies of micronutrients in soils of North Western Zambia. Soil analysis, pot and field experiments were employed to investigate possible deficiencies. The pot experiments investigated how raising soil pH through liming influenced extractable micronutrients and their uptake by plants. Plant Mo and Ca were positively correlated with soil pH, while Mn and Zn were inversely correlated, aggravating the zinc inadequacy on all soils and that for Mn on arenosols. Effects of liming on plant uptakes of micronutrients generally followed the same trends a

Streszczenie:

O crisântemo cultivado em vaso é um dos produtos floríferos mais vendidos na floricultura brasileira, possuindo grande diversidade de cores, formas e tamanhos de inflorescências, além de possuir alta durabilidade após a colheita. Para tanto, é necessário o atendimento das exigências nutricionais da planta para possibilitar expressar seu potencial ornamental. Os objetivos deste trabalho foram analisar o crescimento da planta e caracterizar a marcha de absorção de nutrientes no cultivo em vaso do crisântemo, variedade cultivada ,,Fine Time\". O experimento foi realizado na estufa climatizada do

Long term storage of bauxite residue materials requires a capping stratum which will limit erosion while stabilizing slopes, limit deep infiltration of water into storage piles, and be aesthetically acceptable to the surrounding community. A diverse native vegetative community capable of surviving seasonal drought, low plant available water and nutrient constraints has the best potential of satisfying most, if not all of these requirements. Current and past rehabilitation of residue disposal areas (RDAs) using species native to southwest Western Australia has exhibited varying success. Current

Thesis (MTech (Agriculture))--Cape Peninsula University of Technology, 2017.<br>Cowpea (Vigna unguiculata (L.) Walp) is an important grain and fodder legume grown around the world. It is a dual purpose grain legume crop, providing food for man and livestock. Cowpea is identified as a potential crop to diversify food production, minimize production input by improving soil fertility and improve micronutrients of seed, therefore, improving human nutrition. There is limited information available on cowpea production and suitable agronomic practices including planting date to best suit different en

[Truncated abstract] A greater adoption of stubble retention, minimum-till and no-till farming practices for the purposes of conserving soil, water and fertility requires a greater understanding of the complexity of physical and chemical interactions between the soil and crop residues. There is currently insufficient knowledge to allow reliable predictions of the effects of different residue types in different environments on soil fertility and crop growth, owing to the many residue characteristics and environmental interactions that have been shown to affect decomposition or nutrient release.

The medicinal plants are included within the wide diversity of the MaciÃo de BaturitÃ ecosytem and they are an important component of traditional medicine of this region. However, scientific information that may contribute to the increase in the cultivation of these plants are still rare, particularly at conditions of the State of CearÃ. The overall objective of this project is to evaluate the development and the production of alecrim pimenta (Lippia origanoides) at conditions of MaciÃo de BaturitÃ, CearÃ. Two experiments were conducted, the first during the dry season of 2013 (August to Novem
