With rising fuel prices it is increasingly important that irrigation systems apply water uniformly in order to achieve maximum benefit from the water applied. The uniformity of water application under a center pivot is determined by setting out cans or rain gauges along the length of the pivot, bringing the irrigation system up to proper operating pressure, and letting the system pass over them.

With growing demands for water that is suitable for drinking (potable) 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 resource provides in-depth information on the importance of irrigation water quality, water quality attributes, salts content, toxicity and the sources of toxic components, and bacteria in water sources.

The 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.
