    Humus is the stable organic fraction of the soil that absorbs and holds nutrients in a plant-available form. Humus in the soil consists of different humic substances: • Fulvic Acids: the fraction of humus that is soluble in water under all pH conditions. Their colour is commonly light yellow to Size: 1MB. Humates and Humic Acids. How do they work? by Dr. Boris Levinsky Important role of Humus in agricultural growing is known since ancient times. However, a change from a primitive understanding to serious scientific research had happened only in the middle of the last century, when young scientist from Kherson State University,File Size: KB.

Communications in soil science and plant analysis v no.1 pp. ISSN: Subject: Fourier transform infrared spectroscopy, biochar, corn straw, humic acids, humification, humus, soil, soil organic carbon, thermogravimetry, China Abstract: Straw returning to the field has become a common way to utilize crop residues.

    Humus forms as a result of the complicated interplay between inorganic conversions and organic creatures such as microbes, nematodes, and earthworms. Humus formation is carried out in two steps. First, the organic substances and minerals in the soil disintegrate. Next, totally new combinations of these broken-down products develop. This leads.   The distribution of phosphorus among humus acid groups in different soil types was studied. It was shown that the binding of P with acid-soluble and-insoluble organic components is determined by the acid-base status of soils, which controls the predominant interaction of P with Fe and Al or with Ca and Mg, and the solubility of the resulting organic phosphates in acid and by: 9.

Second type of humus is characteristic for phaeozems, rendzinas, black earths and brown soils. Humic acid/fulvic acid ratio is upper than 1, Extent of aromatic rings condensation is high in humic acids, which cause their hydrophobic properties and inability to creation of chelates.

Humic acids are strongly connected with mineral portion of soil. This water holding capacity of humus is why humus rich soil will remain moist for weeks longer than soil without humus.

Humus has a negative charge which means that many of the nutrients plants require stick to humus, including ammonium (source of nitrogen), calcium, magnesium and phosphorous to. Soil organic matter may be differentiated into humic and nonhumic components.

Humic. components or humus are the highly transformed, dark brown to black materials that are. closely associated with the mineral fraction. Nonhumic material includes both particulate. matter (e.g., dead roots) and simple soluble components that are part of the soil Author: M.R.

Carter, E.G. Gregorich. HUMUS, the black gold of the earth is a book about the most precious substance on our planet. The official scientific name for this stuff is ‘soil organic matter’.

Some scientists have defined humus as ‘the very dead’ ; they see it as the ‘end product of decomposed organic materials’. HUMUS CHEMISTRY arrived very soon after I ordered it. HUMUS CHEMISTRY ihas much information about the chemistry and nature of humus.

Much of the book, however, is devoted to materials and methods. Since Stevenson, the author, is an active researcher, I can understand HUMUS CHEMISTRY's having so much background about materials and by: Other basic gardening soils like clay soils, sandy soils, and loamy soils are all planting soils that react differently with humus.

Clay. One cubic foot of clay every months will help infuse trace metals and other inorganic compounds. Clay will also naturally regulate the acidity of the humus soil.

She has reported at length on the beneficial effects of humus on soil fertility and plant growth, but has largely ignored the data of those workers who failed to get a response to humus, or else got a detrimental Size: 28KB.

Despite the large number of papers and books published on soil organic matter (humus), our knowledge of the subject is still very limited, as is our knowledge of humic acid.

The author of this book began to study humus at the end of the s and continued until when he retired from Nagoya : Humus 26 is an active carbon source. Soil contains living organisms and along with plants needs organic matter (carbon) to thrive. Humus 26 contains humic and fulvic acid, which are the most active components of soil carbon (organic matter).

Soil microbes use active carbon to provide a wealth of soil. Keywords: humus, humification, soil organic matter, paradigm (gestalt) shift, Waksman.

Front. Environ. Sci. doi: /fenvsCited by: 7. Humus is important to the structure of soil. Think of humus like a sponge; nutrients are attracted to the humus particles and may help keep the nutrients from being washed away by rain or watering.

Humus also helps keep soil moist longer than regular composts. The on Humus All fertile soil contains several components: decomposing organic matter, living organisms including plant roots, microbes, worms, insects, and small animals; and humus – the carbon-rich matrix made of fully decomposed organic matter.Humus and partly decomposed soil organic matter can also greatly increase the water- and nutrient-holding capacities of sandy soils.
