Our mission is to conserve the lands and waters on which all life depends

We pursue non-confrontational, pragmatic

solutions to conservation challenges.

What is the Fieldprint Calculator?

An online education tool for row crop farmers that indexes their agronomics and practices to a fieldprint

Helps growers evaluate their farming decisions and compare their sustainability performance 

– In the areas of:• Land use• Soil conservation• Soil carbon• Water use• Energy use• Greenhouse gas emissions• Water Quality• Biodiversity in development

– Against:• Their own fields• Their own performance over time

• County, state and national averages

• Total soil erosion decreased over most of the study period, but has increased more recently (similar for corn)

• Per acre soil erosion decreased during first half of study period, then leveled off (similar for corn, cotton, and wheat)
