Professor Christov’s research centres on soil-moisture physics, plant biophysics, and ecotechnologies for sustainable agriculture, with particular emphasis on the energy-level concept of soil water and its relationship to crop bioproductivity. Through sustained field experimentation, he developed a computerised decision-support ecotechnology for monitoring and managing water status in agroecosystems, demonstrating that precision irrigation based on energy-level principles can reduce water consumption by approximately 30% while increasing crop yields by one-third to one-half. He has authored 223 scientific publications, with sustained commitment to translating fundamental soil physics into practical approaches for farmers and agrarian associations. His representative publications address fundamental concepts in ecology and biophysics, the effects of soil water and nutrient status on crop production, agroecosystem water management, the theoretical foundations of his ecotechnology, and the energy-level concept linking soil moisture with bioproductivity. Collectively, this body of work reflects a career dedicated to connecting fundamental agroecological science with the practical imperatives of water conservation, food security, and environmental stewardship in the Balkans and beyond.
