Our poor knowledge of the structure and formation of humic substances stems from the lack of suitable tools which enable the study of the molecular structure of these complex, yellow-brownish materials. Here, several findings using a combination of isotopic, pyrolytic, microscopic and gas chromatographic methods lead to the proposal of a novel model of

Batch and column experiments were performed to determine the Cu(II) binding capacity of silica-immobilized humin biomass. For column studies, 500 bed volumes of a 0.1 mM Cu(II) solution were passed through humin packed columns at the flow rates of 1, 1.5,

The interdependence between the C and N cycles is reflected by the levels of soil organic matter (SOM). SOM and organic C levels in water soluble (C-WS) humic acids (C-HA), fulvic acids (C-FA), and humin fractions (C-H) were evaluated through the classic

Use of Palm Oil Mill Effluent (Pome) and Peat to Reduce Ammonia Volatilisation from Fertiliser Urea [PDF]
Ammonia (NH3) volatilization is a major pathway of nitrogen loss which limits the efficiency of urea as a fertilizer when surface-applied to soils. High pH and low cation exchange capacity in soils have been identified as the principal causes ofNH3 ...

Transfer hydrogenation of carbonyl and olefinic compounds with the buffer‐free combination of waste‐derived, aqueous formic acid solution and the sulfoShvo catalyst at pH = 1 and elevated temperatures in pressure autoclaves. The OxFA process provides aqueous formic acid (FA) solutions of around 53 wt% directly from biomass‐derived byproducts such as ...

Use of high-dimensional spectral data to evaluate organic matter, reflectance relationships in soils [PDF]
Recent breakthroughs in remote sensing technology have led to the development of a spaceborne high spectral resolution imaging sensor, HIRIS, to be launched in the mid-1990s for observation of earth surface features. The effects of organic carbon content

ВПЛИВ КОМПЛЕКСНИХ МІКРОДОБРИВ НА ОСНОВНІ БІОМЕТРИЧНІ ПАРАМЕТРИ ГІБРИДІВ КУКУРУДЗИ [PDF]
Кукурудза завжди займала провідне місце у зерновому і кормовому балансах України. Вітчизняний науковий досвід показує, що за потенціалом продуктивності зерна та зеленої маси, кормовою й енергетичною цінністю ця культура фактично не має собі рівних і є ...
