Evolution of Prescription Farming

LGSeeds_logo2012LG Seeds shares the evolution of prescription farming.

When we think about technology advancement over the past 20 years a good example is our electronic devices. Smart phones, hand held tablets, sleeker computers; all these devices having data/software storage by the gigabyte and increasing. We live in a technology driven age with demand for real time information. This technology is common place in our society, but has also incorporated itself quite extensively into production agriculture over the past few years.

Prescription Farming at the Beginning
When thinking about prescription farming, variable rate fertilizing and/or seeding, generally comes to mind. Variable rate seeding began with the advent of hydraulic motors serving as the drive or transmission on the planter, giving farmers the chance to change seeding rates on the go. They were also putting GPS receivers and equipment on and in their tractors and combines for auto-steer and yield mapping capabilities.

Prescription Farming Today – Nutrient Application
The evolvement of prescription farming has become more of a streamlined process in farming today. Incorporation of the “smart technologies” into the farm, along with modern GPS/rate controlling equipment
has led to more fine tuning of seeding prescriptions and nutrient application. Nutrient management has seen
an influx of aerial imagery from satellites, airplanes, and now unmanned aerial vehicles (UAV’s).

Prescription Farming Today – Variable Rate Seeding
With past history of yield maps, fertility tests/maps, and topography/soil information for a field, we now have the opportunity to layer different data points on top one another to create more precise seeding zones.

Recently, LG Seeds parent company, AgReliant Genetics, began to do additional hybrid testing beyond traditional strip tests and randomized research yield trials. Testing includes population trials in high, medium, and low yielding environments along with larger strip tests over multiple soil types and topography changes, allowing for multiple data points across hybrid entries at one location. In the future, this data can be coupled with the grower’s yield history and soil tests to get more accurate seeding rates, in the right locations of the field.
