CHARGE DEVELOPMENT AND ACID-BASE CHARACTERISTICS OF SOIL AND COMPOST HUMIC ACIDS
(Sociedad Chilena de Química, 2003)
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 ...
Realistic soil C sink estimate in dry forests of western Argentina based on humic substance content
(Elsevier, 2013-02)
Due to high temporal variation of soil organic matter in arid regions, estimates of annual sequestered C might be overestimate. We assessed the soil stable organic matter (humic substances) in the transitional area between ...
Soaking of Seedlings Roots in Humic Acid as an Effective Practice to Improve Eucalyptus Nutrition and Growth
(Taylor & Francis Group, 2022)
Soil P Diffusion and Availability Modified by Controlled-Release P Fertilizers
(Springer, 2020-11-24)
Slow-release fertilizers have been proposed as tools to increase P fertilizer use efficiency in tropical acidic soils with high P adsorption, low P availability, and mobility. However, results have been controversial since ...
Substâncias húmicas de turfa: estudo dos parâmetros que influenciam no processo de extração alcalina
(Sociedade Brasileira de Química, 2000-08-01)
This study reports the parameters which influence on extraction of humic substances (HS) from peat. The yield, organic and inorganic contend, E4/E6 ratio and elemental composition (C,H,N) of the extracted HS have been ...
