Improved Management of Acid Sulfate Soils for Rice Production in Casamance, Senegal
Casamance is a region in southern Senegal that traditionally produces rainfed rice, but Senegal produces only 1/3 of its rice consumption. Lowland 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 effect...
متن کاملBuffer pH Methods : Ongoing Iowa Laboratory and Field Studies
Soil acidity can affect plant growth directly and indirectly by affecting the plantavailability of nutrients, levels of phytotoxic elements, and microbial activity. Soils may become acidic in the long term as a result of several natural processes. In the short term, however, soil acidity develops mainly due to application of N fertilizers or manure, primarily those having high concentrations of...
متن کاملSoil acidification and the importance of liming agricultural soils with particular reference to the United Kingdom
Soil acidification is caused by a number of factors including acidic precipitation and the deposition from the atmosphere of acidifying gases or particles, such as sulphur dioxide, ammonia and nitric acid. The most important causes of soil acidification on agricultural land, however, are the application of ammonium-based fertilizers and urea, elemental S fertilizer and the growth of legumes. Ac...
متن کاملEffect of liming on soil properties, yield and nutrient uptake by wheat
A study was conducted to evaluate the effects of liming on chemical properties of wheat field soils and yield of wheat in Ranisankail soil series of Bangladesh. There were eight treatments of liming material applied from dolomite (CaCO3.MgCO3). Yield and yield components of wheat were recorded at harvest and the grain and straw were analyzed for P, S, Ca and Mg contents. The post harvest soils ...
متن کاملDevelopment of soil pH and lime requirement maps using on-the-go soil sensors
Since conventional sampling and laboratory soil analysis do not provide a cost effective capability to obtain georeferenced measurements with adequate frequency, different onthe-go sensing techniques have been attempted. One such recently commercialized sensing system combines mapping of soil electrical conductivity and pH. The concept of direct measurement of soil pH has allowed for a substant...
