ABOUT THE BOOK The present book entitle "Vermitechnology, Vermiculture, Vermicompost and Earthworms" reflects the uses of earthworms to degrade some dangerous and toxic weeds which poses a serious environmental health problem throughout the world. The book inculcates about the conversion of some dangerous and toxic weeds into useful manure by using vermitechnology. Moreover, it also presents the comparison between conventional method of composting and vermitechnology using earthworm species Eisenia foetida. I hope that the book will be helpful to scientists, environmentalists, agriculturalist, zoologists, biotechnologist, health scientists, NGOs, researchers and doctors etc. The present research data would be inspirable to the use of vermiculture rather than chemical fertilizer.
