Book Description
A range of products, often referred to as alternative fertilisers, are marketed with numerous claims relating to soil health and improved plant growth. However, there is often an absence of evidence about the veracity of the claims and the effectiveness of these products. Producers and consumers alike are left to rely on the advertised promises which come with little proof. One common group of alternative fertilisers are the humic products that are often sold as soil amendments with or without accompanying plant nutrients. More than 200 humic products are currently manufactured and sold in Australia. Thousands more are available for purchase via overseas websites. Is there a place for humic products in Australian agriculture? Do they have the potential to realise at least some of the advertised claims or are these benefits merely presumption on the part of manufacturers? This technical bulletin ‘Humic products – Potential or presumption for agriculture’ is the first in a series that will cover a range of alternative fertiliser products. Written and produced by NSW Department of Primary Industries, these reports ask two basic questions: Can the product work? Given our current understanding of the physical, chemical and biological mechanisms that interact in soil-plant ecosystems, can we explain how the product functions? Does the product work? Is there sufficient evidence from independent trials that the product will work under field conditions? This publication is written primarily for agronomists, soil scientists, consultants and other farm advisors. However, the readable style, explanations and diagrams provided by the author, Kim Billingham, make it accessible for others with a more rudimentary understanding of the soil and plant sciences. ‘A brief history of humus’ will engage readers from both conventional and more alternative philosophies as we all work towards farming in a more sustainable manner.

Book Description
Humic acids (HA) make up an important component of soil humus related to the maintenance of soil water-holding capacity, stabilization of soil structure and fertility and vital activity of soil micro-organisms, plants and animals. Additionally, obtaining humic substances (HS) from vermicompost has shown to be a promising alternative for large scale use in agriculture. Humic substances (HS) are also major components of natural organic matter (NOM) in soil and water as well as in geological organic deposits. This book includes chapters on vermicompost-derived liquid humus in low-input and small-scale farming; the production of liquid organic fertilizers enriched with humic substances from olive mill wastes; mechanisms of protective action of the HUMI preparation on wheat plant response to toxic ions; the application of surface-enhanced Raman scattering and fluorescence spectroscopy on silver plasmonic nanoparticles as innovative techniques to study humic substances; the complexation of metal ions with humus substances in soils and water and the final chapter examines the natural organic matter in drinking water.

Book Description
Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).

Book Description
Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.
