LUNNYU SOILS IN UGANDA

LUNNYU SOILS IN UGANDA

Автор:

The distribution of lunnyu soils in the Lake Victiria Basin of Uganda is characterized at field and landscape level. All the soil properties, except silt, showed spatial dependence at both depths at the scale of study. Phosphorus, Ca, Na and sand showed shorter ranges of between 42 and 58 meters, all in the top soil, but the other properties in top and subsoil have larger ranges of 149 meters. Lunnyu patches on Chromic lixisol and Mollic gleysols had higher pH, P, sand, clay and silt compared to those on Plinthic ferralsols and Petrifferic lixisol. Neither of the soil properties was influenced by landscape position. Soil pH, Ca, Mg, and K were higher in topsoil compared to subsoil. Neither slope position nor the type of lunnyu has showed consistent differences in all the soil properties. Lunnyu cannot be explained by these two factors. In order to resolve the lunnyu problem, objective identification of lunnyu patches should be sought, followed by careful monitoring of crop performance under different soil fertility management interventions.

Upgrading of Biogas to Biomethane

Upgrading of Biogas to Biomethane

Автор:

In a decentralised energy supply with renewable resources, the use of biogas from anaerobic digestion, gains importance due to the high content of methane and the wide range of applications. The biogas contains 50 – 55 per cent of methane, 40 – 45 per cent of carbon dioxide and hydrogen sulfide in traces. Currently, biogas is mainly applied in small to medium scale heat and power production. However, the high carbon dioxide content reduces the fuel calori?c value and in turn, limits the engine peak power.The traces of hydrogen sulfide produces sulfuric acid, which corrodes the internals of pipes, fittings etc. Therefore, instead of combusting the biogas directly, removing carbon dioxide and hydrogen sulfide contents, and using the biomethane (from biogas) for combustion has been an attractive fuel for IC engines, for power generation, as well as thermal application.
