As with the term CSA itself, this term means many different things to many people. There is no universal definition, but here is a good legal one. Our basic definition is to reduce the need to bring in outside materials to the farm while taking care of the environment (soil, air, water, creatures). We do this in a lot of ways. Examples include good soil management (cover cropping, green manures, no or low till), natural pest control (integrated pest management such as the use of bats and beneficial insects and our fingers to control the pest population, targeted organic pesticides only when necessary), and good water management (drip irrigation, use of rain water). Our goal is a lofty 100% sustainability, and we are working to achieve that.
