On the basis of information on climatic factor, intensity humus formation in soil was estimated. It revealed that as transition from plain to foothills and low mountains due changes atmospheric precipitation hydrothermal regime, period biological activity (PBA) increases mountains. The balance annual radiation foothill is 47 kcal/cm2, high-mountain belt - 53 kcal/cm 2 . As mountainous part reli...

Fulvic, humic, acetic, N-bulyric, formic, lactic, and propionic acids were inhibitory to the survival or reproduction of Aphelenchus avenae, Aphelenchoides goodeyi, Helicotylenchus pseudorobustus, Meloidogyne hapla or Xiphinema americanum. Reproduction of H. pseudorobustus and M. hapla significantly increased with increasing amounts of muck added to sand, and with the initial amount of nematode...

The objective of this study was to investigate the protective effect of dietary natural sorbent-sodium humate (HuNa) on the prevention of aflatoxin B1 (AFB1) toxicity in the broiler chicken. Seventy-two (72) broiler hybrid Hybro birds were randomly divided into 4 groups: control group (G1) and 3 experimental groups (G2-G4) with addition of HuNa (G2); only AFB1 (G3) and HuNa; and AFB1 (G4). HuNa...

The purpose of the present study was to assess the effect of a 21-day feeding of a diet with 1% inclusion of sodium humate (HNa) on the content of trace elements (copper, zinc, selenium, manganese, cobalt) in tissues of weaned piglets, their efficiency and biochemical indicators. Significantly lower content of manganese in livers (P < 0.01) and kidneys (P < 0.05) was detected in piglets fed the...

The effectiveness of various management practices to reduce phosphorus (P) loss from soil to water can potentially be improved by using by-product materials that have the capacity to sorb phosphorus. This study evaluated the P sorption and desorption potential, and the physicochemical characteristics of various phosphorus sorbing materials. Twelve materials were selected and P sorption potentia...

An understanding of sorptive processes is key to describing the fate of chlorpyrifos [O,O-diethyl-O-(3, 5, 6-trichloro-2-pyridyl) phosphorothioate] in aquatic environments. The objectives of this study were to evaluate isotherms for adsorption and desorption of chlorpyrifos on colloidal materials and to advance understanding of interaction mechanisms between chlorpyrifos and colloidal materials...
