Bioactive Compounds in Agricultural Soils (eBook, PDF)

Redaktion: Szajdak, Lech Wojciech

• Format: PDF

Produktbeschreibung

This volume looks at the impact that different cropping systems and tillage have on soil's biologically active substances. It considers how phytotoxins accumulate and can inhibit the development of cultivated plants. Coverage explores the continuous cropping of rye, crop rotation, no tillage, and conventional tillage. It offers a comprehensive, comparative approach to allelopathic plant-soil interactions.

The authors focus on free and bounded biologically active substances such as amino acids, auxins, humic and fulvic acids, transient radicals, and enzymes in light sand soils fertilized with different mineral and organic fertilizers.

The chapters address fundamental questions relevant to the environmental challenges we face today and will deal with in the future. The results involve asking basic questions motivated by soil's chemical and biochemical processes. The answers will lead to the improvement of the quality of soil's organic matter, which, in turn, can lead to increased crop yields.

Readers will come to understand the relationship between ecological processes and environmental change on individual levels of biocomplexity as well as on systems in their entirety. The title is ideal for students and teachers for laboratory practical classes. Soil scientists, biochemists, chemists, plant ecophysiologists, "Natural Products" organic chemists, and other environmental scientists and specialists will also find it useful.

Autorenporträt

Lech Wojciech Szajdak, Professor of Agronomy since 2006, is currently the Director of the Institute for Agricultural and Forest Environment, Polish Academy of Sciences, in Poznä, Poland. He obtained his M.Sc. (Pharmacy) and Ph.D. in 1977 and 1986, respectively, from Poznä University of Medical Sciences. In 2009, he was awarded a Honoris Causa degree from Estonia University of Life Sciences, Tartu. His professional interests are: a) Free and bounded amino acids, phenolic acids, auxins, humic and fulvic acids, transient radicals, enzymes in soils under crop rotation and the continuous cropping of rye, conventional and no-tillage, fertilized with different mineral and organic fertilizers, b) Soil enzymes involved in nitrogen cycle; c) Chemical and biochemical processes and mechanisms in organic soils (peat, moorsh, sapropel) and peatlands in agriculture and the impact of secondary transformed peat soils on the content and properties of hydrophilic and hydrophobic organic compounds of well-known and unknown structure; d) substrates for growing media. Professor Szajdak has written more than 500 research papers, 11 books and 84 chapters in Monographs. He was the guest editor of 2 special issues of Agronomy Research and Plant and Soil "Restoration of Peatlands Soil for Agricultural Use" and "Processes, Mechanism and Use of Organic Soils". He has been a primary researcher in 19 scientific projects.
