    Guidelines for the Four Rs of Fertilizer Management in Horticultural Crops

    Excessive fertilization does not equate to greater crop yields. Crop yields are optimized when nutrients are efficiently used, which requires fertilizer applications to be based on the right source, the right time, the right rate, and the right placement. These are referred as the four Rs of fertilizer management, whose purpose is to supply plants’ nutrient requirements, reduce production costs, and mitigate environmental impact. The original manuscript for this publication was written by Andre Luiz Biscaia Ribeiro da Silva and Erick Smith. It has been reviewed by Tim Coolong.

    Composting: Recycling Landscape Trimmings

    Citizens throughout Georgia are recycling newspaper, cans, glass and plastic in an effort to divert these materials from the waste stream. Another important part of waste reduction involves recycling leaves, lawn clippings, and tree and shrub trimmings instead of placing them curbside for the county or municipality to pick up. These landscape riches from Mother Nature can be easily recycled and turned into nutrient-rich organic matter right in your backyard through a process called composting.

    Keep Wild Radish Out of Fields You Plan to Seed Into Greens!

    This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. The goal of this project was to find potential ways to manage wild radish in seeded greens such as mustard, turnips, collards, and others. Wild radish, a member of the mustard family, has historically been recognized as a winter annual weed mainly infesting winter crops grown across the Southeast. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.
