Dr. Brian Arnall is a precision nutrient management extension specialist for Oklahoma State University. Dr. Arnall’s extension, teaching, and research efforts are focused on precision technologies and nutrient management in all of Oklahoma’s cropping systems with an emphasis in site specific techniques. He works closely with extension educators and industry personnel to improve nutrient management practices that will lead to increased profitability of producers. Dr. Arnall has been involved in sensor based technologies, remote sensing and variable rate application for more than ten years. Brian has more than 50 refereed journal pubs, more than 50 successful grants with total funds exceeding $2.5 million for his project. He has given 600+ talks in 7 countries. His program has produced 35 apps across iOS and Andriod platforms. His work focuses on providing information and tools to producers that will lead to improved nutrient management practices and increased profitability of Oklahoma production agriculture. Dr. Arnall received his doctorate in soil science from Oklahoma State University in 2008. He has served as an extension specialist since the completion of his studies. He teaches courses on Soil Nutrient Management and Precision Ag at Oklahoma State. You can read more about Brian and see some of his research and previous speech topics on his blog at www.OSUNPK.com

He works closely with extension educators and industry personnel to improve nutrient management practices in Oklahoma that will lead to increased profitability of Oklahoma producers. He currently has several ongoing studies focused at the developed of methods to use sensor based technologies, nitrogen fertilizer timing and placement, increasing nutrient use efficiency, and improvement phosphorus fertilizer recommendations. In addition Brian has a crew of developers producing iOS and Andriod applications.
Dr Guillaume K.S. Ezui, a native of Togo, is Cassava Program Manager at the African Plant Nutrition Institute (APNI) based in Nairobi, Kenya.
Dr Ezui has an extensive experience working in the field of crop modelling, soil fertility management, participatory learning and action research in sub-Saharan Africa. He holds a PhD in Plant Production Systems from Wageningen University in the Netherlands (2017), an MSc in Agriculture and Environment Engineering (2010) and a BSc in Crop Production (2001) from the University of Lomé, Togo.
Before joining APNI, he worked for the International Plant Nutrition Institute (IPNI) as Cropping Systems Agronomist (Jan. 2016 to Jun. 2019). In both IPNI and APNI, he coordinates mainly activities of the African Cassava Agronomy Initiative (ACAI) with focus on developing site-specific nutrient management recommendations for cassava production using crop modelling.
Prior to joining IPNI, he worked for 14 years for the International Fertilizer Development Centre (IFDC) in Togo as Agronomist. At IFDC, he contributed to advancing integrated soil fertility management (ISFM), site-specific fertilizer recommendation mapping, participatory learning and action research (PLAR) within multi-stakeholder’s platform settings in West Africa.
Born in Azamgarh, Uttar Pradesh. Dr. Vinod Kumar Singh did his Ph.D in Agronomy from G.B. Pant University of Agriculture and Technology, Pant Nagar (U.K.). Dr. Singh Joined as Joint Director Extension (In-charge), ICAR-Indian Agricultural Research Institute (IARI), New Delhi on 24th January 2020. He is Head, Division of Agronomy, ICAR-IARI, New Delhi-12. Dr. Singh has made valuable contributions in the area of soil fertility appraisal and soil health restoration through site-specific nutrient management (SSNM) and inclusion of legumes in intensive cropping systems. His effort on soil fertility appraisal using geo- statistical tools in different agro-ecologies revealed widespread multi-nutrient deficiencies. The extensive studies by him at cultivators’ fields underlined the significance of SSNM for addressal of multi-nutrient deficiencies, improving yields, nutrient use efficiency and profits under different cropping systems. He also explored, different options for inclusion of legumes in rice-wheat system (RWS) to reduced sub-soil compaction, enhanced organic matter accumulation, and minimized NO3-N leaching.
Dr. Singh has standardized conservation agriculture practices for improving soil health, nutrient and water use efficiency, and net returns. For his pioneering research work in the field of precision nutrient management he got recognized as ICAR-National Fellow (2011-15). The Integrated Farming Systems models developed by him have great potential to raise the income and employment to small and marginal holders. Dr. Singh has published >100 peer reviewed research publications, 08 Books, 12 research bulletin and 18 book chapters. Besides these, he also published his work in popular language for the advantage of farmers and extension personnel. The outcome of his research found wide acceptability and adoption by the farmers in the Indo-Gangetic Plains of India.
He has served as an expert member in DST-BIRAC, FAI, RLBCAU, several SAUs, RLBCAU Jhansi, BOM (IARI), , RAC (BU, Jhansi and BVSPU), BOS (BHU), IMC (DSR, Mau) and Coordinator ANASTU, Afganistan. He possesses an illustrious academic record, with several awards and distinctions viz., ICAR- National Fellow, Fellow of NAAS, Fellow-Indian Society of Agronomy (ISA), Fellow-ISNS, Fellow-SEE, Sukumar Basu Award of ICAR-IARI, NAAS Young Scientist Award, NAAS Associate, FAI Golden Jubilee Award, IPNI-FAI award, PPIC-FAI award, Dr. J.S.P. Yadav Memorial Award of Indian Society of Soil Science, PS Deshmukh Young Agronomist Award of ISA, UPCAR-Young Agricultural Scientist Award, Mosaic Young Scientist Award, Sriram Award and Dhiru Morarji Memorial Award for his outstanding contributions.
