Precision Conservation is a blog with the intent to discover, uncover, and promote new technologies in targeting, planning, and applying soil and water conservation at both field and watershed-level scales. Join us in a weekly discussion of how and why both private and public sector conservationists can and should aim to apply conservation practices in the right place, at the right time, and at the right scale.
I recall hearing a business maxim some years ago: “What gets measured gets done.” In other words, if there is no standard by which to measure something, it becomes a low priority. Unfortunately, this seems to be the case with soil erosion.For years, resource professionals have had the RUSLE2 soil erosion model to predict the amount of sheet and rill erosion that occurs on a farm. Sheet and rill erosion is caused by a shallow sheet of rainwater that runs across the land. This picks up and transports soil particles already detached by a raindrop … [Read more...]
One of the most important data layers in Precision Conservation is the elevation layer, or topographic layer. But, there is one big question that needs to be answered. What is the best data source for Precision Conservation; LiDAR or RTK? The world of elevation data is changing so quickly it is hard to keep up. But even with all of the options the two most common types of elevation data, for conservation planning, are airborne LiDAR and RTK. Given that, which should we choose?On one hand, we have airborne LiDAR data that is collected on a … [Read more...]
"Make everything as simple as possible, but not simpler." - Albert EinsteinIn 2003, Berry et al. defined precision conservation as "a set of spatial technologies and procedures linked to mapped variables, which is used to implement conservation management practices that take into account spatial and temporal variability across natural and agricultural systems.” After reading this I thought to myself, wow, precision agriculture seems pretty complicated.Not that I disagree with Berry’s definition, but I think a more useful definition for … [Read more...]
