About the Author
Dr. Srivastava, is currently the Principal Scientist (Soil Science) at Central Citrus Research Institute (Formerly, National Research Centre for Citrus, Nagpur) under Indian Council of Agricultural Research, New Delhi. He has extensively pursued research work on different aspects of citrus nutrition including nutrient constraints analysis of citrus orchards by developing DRIS-based soil-plant nutrient diagnostics, orchard efficiency modelling, targeted yield-based site specific nutrient management exploiting spatial variability in soil fertility, citrus rhizosphere specific microbial consortium and soil carbon loading, integrated nutrient management module, fertigation scheduling, nutrient mapping using geospatial tools, nutrient dynamic studies, transformation of soil microbial biomass nutrients within citrus rhizosphere and soil fertility mapping as decision support tool for fertilizer recommendation. Dr. Chengxiao Hu, is Director of the International Cooperation and Exchange Division of Huazhong Agricultural University (and the Dean of the International College). He received his B.A., M.S., and Ph.D degree in Agronomy and joined Huazhong Agricultural University. His main research fields include: citrus and main crop rotation formula fertilization technology system, agricultural product safety production and nutrient management, crop molybdenum nutrition mechanism and application of molybdenum fertilizer technology, urban sludge agricultural pollution control principles and technologies, functions mechanisms of mid and micro-nutrients esp. Mo, Se of horticultural plants for edible quality development particularly the sugar / acid ratio, Vitamin C etc. He has presided over in more than 40 projects, including the National Natural Science Foundation, Scientific and Technological Support Program of the Ministry of Science and Technology, the 948 projects of the Ministry of Agriculture, the Ministry of Education and the New Zealand ASIA2000 fund.
