Another way in which CA is looking to the future is through prevention. According to the "European Journal of Agronomy" producers are looking for ways to reduce leaching problems within their fields. These producers are using the same principles within CA, in that they are leaving cover over their fields in order to save fields from erosion and leaching of chemicals (Kirchmann & Thorvaldsson 2000). Processes and studies like this are allowing for a better understanding of how to conserve what we are using and finding ways to put back something that may have been lost before.
