What makes us Different

At Parker Seed Company, we take a different approach to cover crops than other companies or organizations. We believe a cover crop should be designed to meet the producers need and production goals. It should be designed for easy planting as well as the products/varieties utilized in the blend should be locally adapted to the location planted. We do not promote, highly diverse blends. Instead we promote common sense /agronomically correct blends.

The whole problem with the cover crop market today is everyone is continuously trying to re-create the wheel. When the wheel has been created for centuries. The fact is cover crops are not a new idea or concept, farmers and ranchers have utilized cover crops either directly or indirectly for centuries.  

It is important to remember the goal of an agriculture producer is to find "balance" in the practices he or she choose to adopt, he must be efficient, sustainable and most of all do what  he/she can to protect and secure our lands and resources for generations to come.

Common Sense Cover Crop Blends

A common sense cover crop blend is just as it sounds, simply common sense. They are nothing special, they are simple not exotic and most of all productive. The concept behind these blends is that you match varieties/species to provide specific services without completely reducing or diluting the main service producers are trying to achieve. We attempt to match products that have similar growth rates, seed size and varieties that complement each other, not out compete each other. In addition, the varieties utilized in our blends are selected based on the specific soil type and soil pH, rainfall conditions as well as cold tolerance of the location the crop is to be planted. The fact exists, that we can’t efficiently or economically develop a blend that can truly provide every service. We urge producers to choose 1 or 2 main services and focus on doing these services well.   

When we develope our blends we take into consideration the following factors.

  • Overall use and production goals of the producer. 
  • Soil type, soil pH, over all soil fertility
  • Geographical location
  • Planting method-(conventional or no-till)
  • Method and timing of termination- (Mechanicaly, Chemically, or through livestock grazing)
  • Past  pesticide program and fertility program
  • Previous crop as well as following crop to be planted
  • Producers budget
