Overview

Harold van Es is the Chair of the Department of Crop and Soil Sciences and a Professor of Soil and Water Management with extension, research and teaching duties. He also directs the Cornell Initiative on Computational Agriculture. He works in New York, and also has project experience in Central and Eastern Europe, Central America, Africa, the Middle-East, and New Zealand. He has published over 71 refereed papers, co-authored the widely-read book Building Soils for Better Crops, developed several videos in water quality management, wrote numerous extension articles, and advised 45 graduate students.

Research Focus

Current research efforts focus on soil health, precision management of crop inputs, chemical fate in soils, tillage and compaction, and pedometrics

Outreach and Extension Focus

Current extension efforts address soil health, precision nitrogen management, water quality, tillage and compaction related to agricultural and environmental systems.

Instruction Focus

I teach an undergraduate course in Soil and Water Management (4 cr.) and a graduate course in Space-Time Statistics (2 cr.).
