What is agrobiology? (that question is answered); The indivisible kingdom of plants (in which the agrobiology is chiefly interested); Thinking it out (the method of approach is decided on); The first agrobiologists at work (all kinds of plants are scientifically interrogated); Setting up the scale of soil fertility (the zero and the Ioo-point are fixed); Graduating the scale of soil fertility (the points between o and Ioo are filled in); The fertility index (much simpler than one might think); Using the scale of soil fertility (a very important and practical matter); Sources of frustation (some interfering circumstances are identified); The agrobiology evaluation of water (the why, what, when and how of soil moisture); The stand of plants (wherein mass action enters the picture); The quantity of plant life (agrobiologists have a yardstick for that too); More about the formula 318/N (it indicates some wide possibilities); Looking at the limits (Nature is generous but men are mostly inept); Public soil science in the United States (what it is- and isn't); Review of the basal axions (the important principles are recapitulated); Agrobiologic equilibria or end- sates (nature is always arithmetical); Mathematical details (mainly for serious students).

The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance. “Bacteria in Agrobiology: Plant Nutrient Management” focus on the management of plant nutrient to support plant growth and development. The topics treated in this book include mechanisms of plant growth promoting rhizobacteria, zinc and phosphate solubilizing microorganisms, sulfur oxidizing bacteria, ACC deaminase, siderophores, phytohormones, quorum-sensing, biofilms, antibiotics, volatiles, denitrification and integrated nutrient management.

Set includes revised editions of some issues.
