Acidity and chemical properties of Brazilian soils
In soils of tropical climate regions the high acidity and the presence of exchangeable aluminum (Al), associated to low fertility, are the main restrainting factors for agricultural production. A laboratory experiment was conducted using 26 soils of different Brazilian regions, to investigate soil acidity components, giving emphasis to Al and their relations with chemical properties. The pH cor...
متن کاملInfluences of soil acidity on Streptomyces populations inhabiting forest soils.
The Streptomyces populations inhabiting five acidic forest soils were examined. It was found that lowering the pH of a medium selective for streptomycetes (starch-casein agar) to the pH of the particular soil horizon being plated influenced both the total numbers and types of streptomycetes that were isolated from the soils examined in this study. On the acidified medium both the numbers of str...
متن کاملEffects of Building Construction Overburden on Liquefaction Potential of Soils
As one of the significant phenomena in earthquake geotechnical engineering, liquefaction can cause severe damages. A number of factors play a role in the occurrence of liquefaction such as magnitude of earthquake, void ratio, relative density, and fines content percentage. The impact of building construction overburdens on liquefaction is of paramount importance. The present study was aimed at ...
متن کاملThe Effect of Acidity on Turf and the Chemistry of Acid Soils
T FIRST fertilizer plats on this continent devoted to lawn grasses were started by the Rhode Island Agricultural Experiment Station. Sulphate of ammonia and nitrate of soda, alone and in combination, were used as the source of nitrogen. Superphosphate and muriate of potash were added to make a complete fertilizer. The plats were laid down in 1907 and were fertilized continuously until 1942, whe...
متن کاملThe Effect of Soil Acidity on Sugar Beet Growth Some Natal Soils
During the latter part of 1975 an investigation was conducted in the Natal Midlands to locate sites, representative of the main bioclimatic subregions, that would be suitable for sugar beet experiments. Soil acidity was identified as an important limiting factor in the majority of soils examined. A glasshouse study with sugar beet revealed a marked response to lime where soil pH values were les...
