This Textbook on “Geo Informatics and Nano Technology in Precision farming” is remarkable in throwing light on the spatial aspects such as precision farming, data acquisition system, multispectral remote sensing, remote sensing in thermal infrared region, using G I S, GPS, remote sensing in yield monitoring, soil mapping for land use and land cover detection, fertilizer recommendations, and satellite image interpretation and Nano Technology. This is the first comprehensive study on Geo-informatics meant for students and professionals which brings together the essential elements of Remote sensing, GPS and GIS in the field of agriculture and allied science. This textbook is conceptually divided into four parts and the chapters of the textbook have been arranged in a rather classical set-up so that it is easily understood for all, UG and P.G students. This book gives the information from land preparation to harvesting of crops using Nanofertilizers, nano-pesticides- nano-sensorsimportance and advantages– strategies. This book is a valuable resource for all B.Sc(Ag), M.Sc(Ag) and Ph.D (Soil Science & Agronomy) students and also highly use full for JRF and SRF exams conducted by ICAR and other competitive exams.
