Nutrient management in commercial crop production is challenging. Growers must incorporate numerous physical, chemical, biological, social and economic factors into their decisions on how to best “feed” crops within a sustainability-minded business context. This process is particularly challenging for organic growers unable to employ consistent, nutrient-dense fertilizers of various formulations in ground and foliar applications. The Penn State Univ. team of Elsa Sanchez and Heather Karsten help de-mystify organic whole farm nutrient planning in a summary of their work completed with farmers and extension professionals.
