    Hurricane and Wind Damage to Trees and Shrubs in Nurseries

    Renewed

    Damage to perennial woody trees and shrubs caused by hurricanes or high wind events is often not initially apparent. In some cases, it can take months or even years to manifest, despite plants looking relatively healthy after initial inspection by growers and insurance adjustors. This publication describes common damage seen in perennial woody trees and shrubs after a hurricane or high wind event.

    An Introduction to Hemp Chemistry and Lab Results

    Revised

    With the passage of the 2018 U.S. Farm Bill, industrial hemp was declassified as a Schedule I drug and is now legal (with restrictions) for production in the United States. Hemp and marijuana are both Cannabis sativa but are distinguished from each other based on the concentration of the psychoactive compound, tetrahydrocannabinol (THC). Industrial hemp is defined by law as a cannabis plant with total THC concentrations on a dry weight basis of less than 0.3% (+/- a measurement of uncertainty). This resource provides a basic overview of hemp testing for THC to stay in compliance with U.S. Department of Agriculture rules for hemp growers.

    Cover Crop Biomass Sampling

    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. This resource covers taking a representative sample, preparing a sample for the lab, and provides a guide to help you calculate wet and dry weights.

    Organic Poultry Production vs. Other Systems

    There are a number of different poultry production systems available today, and consumers commonly confuse organic poultry production with other systems. Pasture-raised poultry and natural poultry are not organically produced, as they do not meet all or any of the standards set by the National Organic Program, which regulates and certifies production systems as “organic.” Consumers should be aware of the differences between each of the poultry production systems as they purchase poultry products.

    How Wetlands Benefit Georgia Agriculture

    Many people view wetlands as “wastelands,” having few virtues. But it is now known that wetlands provide many useful services, from improving water quality to providing habitat for important fish and wildlife. These kinds of benefits would be costly to create, so maintaining natural wetlands is good for both the economy and the environment. Many smaller wetlands occur in Georgia farmlands, and many of the values provided by wetlands benefit Georgia farmers. This resource highlights the key virtues of wetlands to agriculture, describing how wetlands associated with Georgia farms can contribute to agricultural value.

    2026 Corn, Soybean, and Wheat Outlook

    The key points for the 2026 season are: Large ending stocks from 2025 mean that prices will likely remain low during 2026. Tight margins are expected to continue in 2026 as projected prices for corn, soybeans, and wheat are near or below the breakeven cost of production. In Georgia, growers are likely to plant more corn acres, while soybean and wheat plantings will be comparable to last year.

    2026 Peanut Outlook and Market Situation

    The key points for the 2026 season are: High peanut acreage is expected to continue into 2026, keeping overall U.S. and Georgia production elevated. Oversupply will keep prices under pressure, with Georgia forward contracts likely in the range of $425–$500/ton. Exports and profitability remain challenged, underscoring the need for new markets and stronger demand to support grower returns.
