RenewedWith growing demands for potable (suitable for drinking) water (due to population increase) and expanding irrigated acreage, there is an increased pressure on irrigated farms to consider using nonpotable alternatives. However, low quality irrigation water can adversely affect soil physical conditions and crop production.
This publication provides in-depth information on the following aspects of agricultural irrigation water quality:
-Importance of irrigation water quality
-Major attributes of irrigation water quality
-Common units used
-Salts content
-Toxicity and their sources
-Bacteria in water sources|

RevisedThe Joro spider is native to East Asia and was first detected in Georgia in 2014. Adult females become sexually mature in September and early October. The female is bright yellow with broad, horizontal bluish-green bands on the top side of the abdomen, large red markings on the bottom side of the abdomen, with long, black legs with yellow-orange bands. The male’s cephalothorax is light brown with two dark brown long bands on both sides. His abdomen is elongate-oval with a greenish-brown topside that has two yellowish long stripes on both sides of the dark brown middle line.

This resource provides an overview of water spinach cultivation for Georgia. Water spinach is an important part of the cuisine of a number of cultures. However, it can spread easily in waterways and is considered a noxious weed in many places. This resource addresses responsible production of water spinach, if permitted by the state of Georgia.

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.

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.

This resource is for university researchers and Extension specialists, county Extension agents, and producers of livestock, forages, and feeds. It highlights the role of selenium in animal nutrition; selenium concentration and distribution in soils and feedstuffs (grains and forages) produced in various parts of the United States and in Georgia; disorders resulting from selenium deficiency or toxicity; various methods of selenium supplementation; and recommendations for selenium management in Georgia.

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.

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.
