Improved Management of Acid Sulfate Soils for Rice Production in Casamance, Senegal
… areas, where rice is primarily produced, have acid sulfate soils with low pH and potential aluminum and iron toxicity. The goal of this work was to determine if soil amendments can alleviate soil acidity, counteract the negative biogeochemical effects that occur in flooded conditions, and …

Influence of pH, phosphorus addition and soil water content on phosphorus pools in acid sulfate soils
Acid sulfate soils (ASS) are common in wetlands and important for crop production. However, little is known about P availability in ASS which is constrained due to high Fe content and changing redox potential. This thesis aimed to investigate the effect of P addition, pH and soil water content on P …

Application of fuzzy logic, GIS and remote sensing to the assessment of environmental factors for extensive brackishwater aquaculture in Indonesia
… aquaculture. The soil assessment focussed on acid sulfate soils (ASS) and sandy-textured sediments in Aceh, and the hydrological study focused on investigating important wave parameters that influence the suitability of coastal areas for siting extensive pond units in South Sulawesi. The study …

Improving Pearl Millet (Pennisetum glaucum (L.) R.Br.) Productivity in Salt-affected soils in Senegal: A Greenhouse and Field investigation
… the Senegalese "Peanut Basin" include salinity, acidity, and fertility. Crop yield may be increased by use of soil amendments and salt-tolerant cultivars. Objectives of this research were to evaluate salt tolerance of various millet (Pennisetum glaucum (L.) R.Br.) cultivars and compare effects of …

The Chemodenitrification of Nitrate by Green Rust and Mackinawite and its Geochemical Implications
… chemodenitrification kinetics were faster at acid pH values, in disagreement with thermodynamics, this observation most likely resulted from the higher reactivity of a soluble reductant or possibly FeS oxidation products precipitating at higher pH values passivating redox-active surfaces. …
