Humic & Fulvic Acids: The Black Gold of Agriculture?

Humic & Fulvic acids based specialities, mainly deriving from Leonardite, are increasingly popular in organic farming of course but also in conventional outdoors horticulture, greenhouse cropping and even in the broad acre sector. Leer más

Humic Acids Technical Evaluation Report USDA National Organic Program

Humic substances are a group of complex organic compounds consisting of humic acids, fulvic acids, 23 natural salts of these acids (e.g., calcium humates), and sponge-like substances called humin (Weber, 24 undated). Leer más

„Effect of Biostimulant CYT14 Standard Foliar Application Rate“ by Dr. Yasser Dergham

Two experiments were applied with 1 О treatments ( each repl icat-ed three times): ln young leaves, СУТ14 consis-tently enhanced copper concen-tration in fully developed young leaves treated with five different forms of copper. СУТ14 enhanced iron concentration in fully devel-oped young leaves treated with iron salts, lignosulfonates, EDTA and am1no acids. Leer más

„The Humus Cycle“ by Dr. William Jackson

Renewable Farming By Dr. William Jackson Summary: Humic material is what makes the whole soil and crop bio-cycle go around. If our soils don't have it, they short-circuit and end up with such stress we'll have to pay for later. Microbial digestion builds humus, and thus enhances topsoil.  Leer más

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, Ukraine, Lydia Khristeva had made a simple experiment. Leer más

„Definition of soil organic matter“ by Jerzy Weber

Definition of humic substances Agriculturist since ancient times have recognized significant benefits of soil organic matter (SOM) to crop productivity. These benefits have been the subject of controversy for centuries and some are still debated today. Leer más

„Humus still a Mystery“ by Paul Sachs

Humus is like air in a sense. It is abundant, renewable and essential for life to exist on this planet. However, humus is so much more complex han air that even after hundreds of years of research, no one really knows exactly what it is. Leer más

„Research Regarding Arkansas Lignite and Its Possible Use As a Soil Amendment“ by Dr. Stephen W. Kline and Dr. Charles E. Wilson, Jr.

What follows is a proposal that was drafted in 1994 for experimentation with Arkansas lignite to test certain agricultural products that can be produced from lignite. Leer más

„A review of humus and humic acids“ by T. L. Senn and R. Kingman

The term "humus" dates back to the time of the Romans, when it was frequently used to designate the soil as a whole. It was later applied to the organic matter of soils and composts or to different fractions of this organic matter, as well as to complexes formed by the action of chemical reagents upon a variety of organic substances.

„Effects of Biostimulators on Growth and Physiological Reactions of Vegetables“ by Dr. agr. Yaroslav Shevchenko

Plant production in hydroponical systems is under scientific investigation since early sixties of the last century (BENOIT and CEUSTERMANS 1994). Gained systematic knowledge about benefits and shortcomings of soilless culture allowed its use in commercial vegetable growing (LEEMAN et al., 1995). Leer más

„Response of Growth and Yield of Ocimum Basilicum with Application of Humic Acid“ by Ameri, A., Aminifard, M. H., Fatemi, H., Aroiee, H.

Partial of natural organic material in soils, waters and sediments are humic substances which they have complex chemical structures and more stable than their precursors and have lost their chemical characteristics. Leer más

„Iron Supply of Cucumbers in Substrate Culture with Humate“ by Boehme, M.; Shevtschenko, J.; Pinker, I.

Plant cultivation in hydroponical systems is quite problematic concerning the proper balancing of the nutrient supply. According to previous investigations, humates seem to have a particular favourable effect on the nutrient supply. Leer más

„How Humic Substances Help Turfgrass Grow“ by Schmidt, R. E. PhD; Zhang, Xunzhong PhD.

Man has realized for thousands of years that dark-colored soils are more productive than light-colored soils and that this productivity is closely associated with decaying plants, animal residues and microorganism bodies. Leer más

„Evaluation of the Performance of Humic Acid Products in Turfgrass Management“ by Carey, K; Gunn, E.

The purposes of this project were to determine the effects on turfgrass performance of various humic acid products applied with a regular turfgrass nutrition program and determine differences between granular and liquid formulations of humic acid products with respect to turfgrass performance. Leer más

„Influence of Humic Acid on Kentucky Bluegrass Establishment“ by Van Dyke, Adam

This study tested a humic acid material at two application rates and two application schedules applied in combination with a starter fertilizer. Leer más

„Humic Substances Influence Creeping Bentgrass Growth“ by Liu, Chunhua PhD; Cooper, Richard J. PhD.

In recent years, many commercial products containing humic substances have been promoted for use on turfgrasses. Although the effects of humic substances on cereal grasses and numerous other plants have been studied for some time, their effects on turfgrass growth have not been well documented. Leer más

„Answers to Some Questions Golf Course Superintendents Have Concerning the Use of Biostimulant“ by Schmidt, Prof. em. R. E.; Ervin, E. H.

In talking with several golf course superintendents we became aware that some confusion might exist in determining the best way to incorporate biostimulant treatments to enhance a turfgrass nutrient program. Leer más

„Influence of Plant Growth Regulators on Turfgrass Growth, Antioxidant Status and Drought Tolerance“ by Xunzhong Zhang

A series of studies were conducted to examine the antioxidant status, drought and disease tolerance, and growth response to foliar application of soluble seaweed (Ascophyllum nodosum) extracts (SE) and humic acid (HA; 25% active HA or 2.9% active HA) in tall fescue (Festuca arundinacea Schreb), Kentucky bluegrass (Poa pratensis L.) and creeping bentgrass (Agrostis palusttis Huds.) grown under low (-0.5 MPa) and high (-0.03 MPa) soil moisture environments.
