CHARGE DEVELOPMENT AND ACID-BASE CHARACTERISTICS OF SOIL AND COMPOST HUMIC ACIDS
(Sociedad Chilena de Química, 2003)
Effects of superficial liming and silicate application on soil fertility and crop yield under rotation
Soil acidity and low natural fertility are the main problems for grain production in Brazilian 'cerrado'. Although lime has been the most applied source for soil correction, silicate may be an alternative material due to ...
Nitrate Reductase, Micronutrients and Upland Rice Development as Influenced by Soil pH and Nitrogen Sources
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 ...
Effects of physicochemical soil properties of five agricultural soils on herbicide soil adsorption and leaching
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2011)
ACIDS SOILS PH AND NUTRIENT IMPROVEMENT WHEN AMENDED WITH INORGANIC SOLID WASTES FROM KRAFT MILL
(Sociedad Chilena de Química, 2007)
Nutrient accumulation and biomass production of alfafa after soil amendment with siliciates.
(Revista Ceres, v. 61, n.3, p. 406-413, 2014., 2014)
Genetic effects for maize traits in acid and non-acid soils
(Sociedade Brasileira de Genética, 2008)
Breeding programs for acid-soil tolerance are desirable as a relatively inexpensive and permanent way for increasing maize (Zea mays L.) yield on these soils. Our objective was to compare the genetic effects controlling ...
EVOLUTION PATTERNS OF THE SOIL ORGANIC-MATTER IN SOME AGRICULTURAL SYSTEMS IN THE BRAZILIAN CERRADO REGION
Several changes in the soil humus characteristics were observed after clearing the Central Brazil virgin forest. When compared with the original ''Cerrado'' forest, the soils from the agricultural systems showed increased ...
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 ...
