Chemical and physical properties of humic acids (HAs) isolated from Mudbanks (locally known as “Chakara”—a unique phenomenon occurring along the south west coast of India during the southwest monsoon...
In this study, the effects were investigated of salinity, foliar and soil applications of humic substances on the growth and mineral nutrients uptake of Corn (Hagein, Fardy10), and the comparison was ...
The aim of our work was to characterise the stability, humification degree, and principal classes of fluorophores in humic acids isolated from different matrices. Soil humic acids were isolated from a...
The aim of the present paper was to determine hydrophilic and hydrophobic properties and the degree of polydispersity of humic acids depending on their degree of maturity and the properties of the pla...
Soil phosphorus (P) can exist in various inorganic (Pi) and organic forms (Po). Specific determination of Pi can be obtained by fractionate methods. However, the discrimination between the chemically ...
Desorption of pyrene and phenanthrene, from two charcoals and humic acid preloaded charcoals werestudied. Desorption occurred obviously in two fractions, with rapid and slow desorption rate constantra...
Luvisols and Cambisols are two types of sub-boreal soils, which are known as continental and humid-ocean types of soils in deciduous forests respectively. Morphological features of soil, which are fre...
The paper presents the findings of the experiments conducted on a clay loam gleyic Cambisol mical Research in 20072008. The tests were designed to establish the effects of the use of perennial grass...
Farming systems strongly affect soil humus. In this study some humus characteristics were used to compare the humus quantity and quality under two different farming systems. The field experiment was e...
Atmospheric aerosols play significant roles in climatic related phenomena. Size, density and shape of particles affect their fluid-dynamic parameters which in turn dictate their transport and lifecycl...
The authors characterized selected surface properties of humic acid preparations extracted from three types of Polish soils (degraded chernozem developed from loess, grey-brown podzolic soil developed...
