Bacterial Diversity in Soil in Response to Different Plants, Phosphate Fertilizers and Liming
The diversity of bacterial isolates from soil in response to different plants (control, Brachiaria ruziziensis and Cajanus cajan), fertilization (control, simple superphosphate and rock phosphate) and liming (with and without lime) was evaluated. Phenotypic and physiological characteristics of the isolates were recorded and organized in a file to identify the bacteria. Among the isolates, 95% w...
متن کاملUse of pulp mill inorganic wastes as alternative liming materials.
A laboratory aerobic incubation study was performed during 18 weeks under controlled conditions to assess the effects of applying different doses of pulp mill inorganic wastes on the physical-chemical properties of an acid Dystric Cambissol. Three different inorganic wastes were tested - wood ash, dregs and grits, and an agriculture limestone was used as reference. Results showed that increasin...
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 کاملSOIL pH AND LIMING
When crops do not grow well, one of the first question an agronomist is likely to ask is “What is the pH of the soil?” The reason for this question is that soil pH tells us more about a soils ability to produce crops that any other single measurement. A measurement of soil pH is like a doctor’s measurement of a patient’s temperature. It gives an indication something may or may not be wrong, but...
متن کاملSoil Acidity and Liming
Soil pH, soil acidity, and their effects on plants The pH scale, ranging from 0 to 14, is used to indicate acidity and alkalinity. pH is a measure of the concentration of hydrogen ions (symbol = H) in the water contained in the soil. A pH of 7.0 is neutral, values below 7 are acidic, and those above 7 are alkaline (basic). The lower the pH, the more acid the soil. Each unit pH drop indicates te...
