My program, including extension, research, and teaching responsibilities, focuses on sustainable and organic fruit crops farming systems, especially citrus nutrition with controlled-release fertilizers, poultry litter, other non-synthetic materials and alternative weed management methods. Sustainable agriculture, organic farming, and the more consumer-oriented ecolabeling movement pose social, political, and economic options, important not only to farmers and consumers but also to more conventional growers and consumers who may, by choice or regulation, come to incorporate many of these sustainable concepts and practices as well. Details and additional information are available at the below links.
