This week is the second half of our conversation with Zack Grant about urban farming and dealing with contaminated soils. Zack details techniques that urban farmers and gardeners can use to avoid growing in contaminated soils. We also dive into the importance of soil testing and how to pick a soil lab and use the results to guide your amendment decisions. Throughout this process, Zack keeps bringing up the key point that often we can overdo it with amendments. He mentions how compost can become a major water polluter if used too ambitiously.
