Influence of Urea and Ammonium Sulfate on Soil Acidity Indices in Lowland Rice Production
(TAYLOR & FRANCIS INC, 2010)
Urea and ammonium sulfate are principal nitrogen (N) sources for crop production. Two field experiments were conducted during three consecutive years to evaluate influence of urea and ammonium sulfate application on grain ...
THE EFFECT OF ORGANIC MATTER AND SOIL CHEMICAL PROPERTIES ON SULFATE SORPTION IN CHILEAN VOLCANIC SOILS
(SCIENCE PUBLISHERS, INC., 2005)
Almost 70% of the volcanic ash-derived acid soils in Chile are deficient in plant available sulfur (S). Furthermore, the low organic matter mineralization rates in these soils necessitate regular application of S fertilizers ...
Patagonian salt marsh soils and oxidizable pedogenic pyrite: solid phases controlling aluminum and iron contents in acidic soil solutions
(Springer, 2018-12)
The sulfidic materials present in salt marshes could be oxidized forming sulfuric acid, increasing the toxic levels of both Al and Fe available to plants. The objectives of this study were: (a) to evaluate the mechanism ...
Assessment of acid-sulfate drainage in an environmental liability associated with an ancient sulfuric acid industry in a sector of the Río de la Plata coastal plain: Impacts on soil and water quality
(Springer, 2021-04)
Environmental liabilities have become one of the most important problems at environmental level, especially those located in urban areas. Within the area of the Río de la Plata coastal plain, industrial waste abandoned by ...
Nitrate Reductase, Micronutrients and Upland Rice Development as Influenced by Soil pH and Nitrogen Sources
(2017-12-16)
The average yield of upland rice under no-tillage system (NTS), a sustainable soil management, is lower than in conventional tillage (one plowing and two disking). One of the reasons given for this drop in crop grain yield ...
