Alternatives to Synthetic Herbicides for Weed Management in Container Nurseries (B 1410) Weed management is one of the most critical and costly aspects for container nursery production. High irrigation and fertilization rates create a favorable environment for weed growth in addition to crop growth. Weeds can quickly out-compete the crop for light and other resources, reducing the rate and amount of crop growth as well as salability. Weed management in nursery production is most effec…
An Introduction to Conservation Tillage for Vegetable Production (B 1539) Conservation tillage with agronomic crops (i.e., cotton, corn, soybeans, etc.) has been successful in Georgia production. Such production practices have several benefits, the most notable being the elimination of soil erosion. Other benefits include but aren't limited to increases in soil organic matter, maintaining a healthy rhizosphere (root-zone soil), reduction of riparian and waterway polluti…
Beneficial Insects, Spiders, and Mites in the Southeast (C 1055) The purpose of this guide is to help users identify insects, spiders and mites that are beneficial to the garden. Such beneficials help manage pests that can damage plants. Tips to conserve and protect beneficials are also included.
Biochar Basics Series: Biochar Basics: An Introduction to Biochar as a Container Substrate Component (C 1292-01) Additional author: Mengmeng Gu, Professor, Colorado State University Department of Horticulture and Landscape Architecture. Biochar has been proposed to be beneficial to the environment and plants. However, many people do not know what biochar is, what can biochar do, or how biochar can be used. In Part 1 of this publication, we provide introductory information on biochar used to partially replac…
Biochar Basics Series: Biochar Basics: Biochar Properties and Making the Right Biochar Mix (C 1292-04) Additional author: Mengmeng Gu, Professor, Colorado State University Department of Horticulture and Landscape Architecture. Container substrates must fulfill several functions for plant growth: create a suitable environment for root growth, physically support them, hold nutrients and water, and enable gas exchange between the roots and the atmosphere. Suitable physical and chemical container subst…
Biochar Basics Series: Biochar Basics: Effects on Plant Disease (C 1292-03) Additional author: Mengmeng Gu, Professor, Colorado State University Department of Horticulture and Landscape Architecture. How does biochar play a role in a plant-disease system? Briefly, before the pathogen infects plants, biochar can improve plant growth by increasing water and nutrient uptake, a healthier plant may be more resistant to attack. On the other hand, after a pathogen infects the pl…
Biochar Basics Series: Biochar Basics: Effects on Plant Growth (C 1292-02) Additional author: Mengmeng Gu, Professor, Colorado State University Department of Horticulture and Landscape Architecture. Is Biochar Good or Bad for Plant Growth? Mixing biochar into soilless substrates may have negative, zero, or positive effects on plant growth. Biochar made from green waste mixed with peat at 50% by volume has been shown to increase prayer plants' total biomass and leaf surf…
Common Labels and Certifications Used to Market Sustainable Agriculture Products (C 1129) Label terms and certifications can be divided into those that are regulated and those that are unregulated. Regulated label terms and certifications are usually defined by the United States Department of Agriculture (USDA) or the Food and Drug Administration (FDA). Within the USDA, the Food Safety and Inspection Service (FSIS) is the agency responsible for the truthful labeling of meat and poultry…
Compost Utilization for Erosion Control (B 1200) Composting is the controlled biological process of decomposition and recycling of organic material into a humus-rich soil amendment known as compost. Mixed organic materials such as manure, yard trimmings, food waste and biosolids must go through a controlled heat process before they can be used as high quality, biologically stable and mature compost (otherwise it is just mulch, manure or byproduc…
Conservation and Best Management Practices in Georgia: Implementing, Funding and Assistance (B 1335) Best Management Practices (BMPs) can be described as management and/or structural practices that are designed to reduce pollutants and erosion while increasing the quality of all life. The BMP concept deals specifically with nonpoint source pollution, such as runoff from agricultural fields, forest areas or urban areas. Best management practices are also voluntary in nature. Individual practices a…
Cover Crop Biomass Sampling (C 1077) Cover crops are one of the most important practices that farmers can use to improve their soils and the sustainability of their production system. Knowing how much biomass there is in a field is a critical piece of information for cover crop management. Part 1 of this circular provides a step-by-step guide to taking a sample that will be representative of your field. Part 2 provides additional ste…
Organic Cover Crop Seed Production in Georgia (B 1436) Cover crops are in essential part of an organic production system. Cereal rye and crimson clover are cover crops that are commonly used. If organic cover crop production is a viable enterprise for growers, it could improve the availability of varieties adapted to the Southeast; provide a source for locally grown seeds; and be another profit center for growers, seed cleaners, and local seed compani…
