Thirty-six selected male chickens were allocated into four groups C, HA, ZN, ZN + HA, and the experiment was initiated after 4 days of an adaptation period. Group C was fed a complete feed mixture wit...
Forty female chickens were allocated to four groups of ten birds each. The control group (K) was fed a basal diet without supplementation. The second control group received a basal diet with humic aci...
Forty randomly selected chickens were allocated into four groups: K, HA, Cd and Cd + HA. After a 5-day adaptation period, the experiment was initiated. Group K was fed a diet without supplements. Grou...
A study was under taken to investigate the effect of dietary supplementations of humic acid and esterified glucomannan) on broiler performance and the morphological measurements of small intestine. Tw...
Humic acid-like substances (HALS) are heterogeneous macromolecules having a range of physicochemical properties and exhibiting different reactivities in environmental systems. However, to study the H...
Effects of pH, Eu(III) concentration, ionic strength, temperature and humic acid (HA) on Eu(III) sorption to iron oxides were investigated in detail. The sorption of Eu(III) to iron oxides was signifi...
Sorption of U(VI) from aqueous solution to Na-attapulgite was investigated at different experimental chemistry conditions by using batch technique. The attapulgite sample was characterized by FTIR and...
The sorption of Eu(III) on calcareous soil as a function of pH, humic acid (HA), temperature and foreign ions was investigated under ambient conditions. Eu(III) sorption on soil was strongly pH depend...
Two field experiments were carried out in the experimental station of the National Research Centre at EL-Nubaria, EL-Behira Governorate, Northern Egypt, to study the effect of 12 treatments, which we...
The effective removal of humic acid is an important factor influencing the quality of treated waters. Adsorption is one of major techniques used for the removal of humic acid. This study demonstrated ...
Potato crop (Solanum tuberosum L.) is one of the most important vegetable crops in Egypt. Integrated treatments between humic acid at concentrations 6.0 or 8.0 ml / l followed by sulfur at 3.0 or 4.0...
The effect of soil drenching with humic acid and commercial biofertilizers i.e., phosphorien , microbien and/or cearalien were evaluated for controlling dry root rot disease of mandarin ,fruit qualit...
The aim of this study is to investigate the effects of different humic acid and phosphorus levels on corn plant ( Zea mays L.) growth and P availability in a calcareous soil. Four levels of P (0, 20,...
The phase transitions and hygroscopic growth of two humic acid aerosols (Aldrich sodium salt and Leonardite Standard (IHSS)) and their mixtures with ammonium sulphate have been investigated using a co...
The interactions of aerosols consisting of humic acids with gaseous nitrogen dioxide (NO2) were investigated under different light conditions in aerosol flow tube experiments at ambient pressure and t...
