Interaction of earthworm

Ebook "Intestinal microorganisms of termites and other invertebrates" focuses on the microbes in gut systems of soil animals. It starts with a profound overview of the biology of soil invertebrates. A major part deals with the gut microbiota of termites, the best investigated gut system of invertebrates. Termites are important soil processors in tropical and subtropical regions.

Vermi-compost being potential organic manure is gradually getting popularity among farmers and also farmers are gradually becoming well aware about the beneficial role of earthworm. Again while the focus is on reducing the use of chemicals in crop cultivation use of bio-agents has also got immense importance. Accordingly research work focusing on enrichment of vermi-compost with different beneficial bio-agents and its different aspects are the primary need.

Vermicomposting is a cost–effective and eco-friendly process used to treat organic waste. Vermicompost is nutrient rich organic compost with active microorganisms resulting from the interaction between earthworm and microorganisms on the breakdown of organic matter. Earthworms convert the waste material in to small particles by breaking in the gut of earth worm obtaining nutrients from the microbes that harbor on them.

Vermicompost is a nutrient-rich, microbiologically-active organic amendment that results from the interactions between earthworms and microorganisms during the breakdown of organic matter. It is a stabilized, finely divided peat-like material with a low C:N ratio, high porosity and high water-holding capacity, in which most nutrients are present in forms that are readily taken up by plants.

This volume is an update of the book, Soil Sampling and Methods of Analysis, first published in 1993. The aims of this second edition remain the same as those of the earlier edition—to provide a compilation of soil analytical and sampling methods that are commonly used, straightforward, and relatively easy to use. The materials and procedures for these methods are presented with sufficient detail and information, along with key references, to characterize the potential and limitation of each method....

During the past two centuries, scientists, farmers, and agricultural educators have tended to alternate their views of soil organic matter (SOM) between the extremes of great appreciation and low esteem. As an early 20th century bulletin explained, organic matter was “once extolled as the essential soil ingredient, the bright particular star in the firmament of the plant grower…” before it “…fell like Lucifer…” as a result of the findings of 19th century agricultural chemists that most of the plant structure (C, that is) originated in the atmosphere (Hills et al., 1908)....
