CHARGE DEVELOPMENT AND ACID-BASE CHARACTERISTICS OF SOIL AND COMPOST HUMIC ACIDS
(Sociedad Chilena de Química, 2003)
Crop Response to Soil Acidity Factors in Ultisols and Oxisols in Puerto Rico. XII. TomatoesTítulo en inglés.
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1985)
Soil Fertility, Sugarcane Yield Affected by Limestone, Silicate, and Gypsum Application
(Taylor & Francis Inc, 2017-01-01)
The aim of this study was to verify if the application of silicate or lime, in association with gypsum, on sugarcane residue can lead to amendment of subsurface soil acidity, increasing sugarcane yield and profitability. ...
Effects of superficial liming and silicate application on soil fertility and crop yield under rotation
(2013-03-01)
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
(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 ...
Genetic effects for maize traits in acid and non-acid soils
(Sociedade Brasileira de Genéticahttp://bit.ly/16Q0MSB, 2013)
Crop rotation in no-till soils modifies the soil fatty acids signature
(Wiley Blackwell Publishing, Inc, 2018-09)
Analysis of whole-soil fatty acids (WSFA) was used to characterize no-till productive agricultural soils associated with different crop rotation managements on the Argentinean pampas, over two sampling seasons. Crop rotation ...
Influence of soil use on organic carbon and humic substances of an oxisol in tropical systems
(2012-08-01)
The conversion of native forests in crop systems affects the equilibrium of the soil organic carbon (SOC). The objective of this study was to evaluate the contents of SOC and humic substances (humin, humic acid, and fulvic ...
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)
