Studies have concluded that …
- Essential pH Management in Greenhouse Crops: pH and Plant Nutrition (B 1256) Your goal as a greenhouse grower is to maintain a stable pH over the life of the crop. This is not an easy task since many factors can affect pH in the growing substrate. The pH can go up or down within several weeks of the crop cycle and if you wait for deficiency or toxicity symptoms to develop, you have already compromised the health of the crop and you r profits. Knowing all factors involved i…
- Evaluating and Interpreting Application Uniformity of Center Pivot Irrigation Systems (C 911) 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.
- Factors to Consider in Selecting a Farm Irrigation System (B 882) The majority of agricultural irrigation systems in Georgia fit into one of two broad categories: sprinkler irrigation and micro-irrigation. Sprinkler irrigation systems include center pivot, linear move, traveling gun, permanent set and solid set. Micro-irrigation systems include drip (or trickle) irrigation and micro-sprinklers. No one system is best for every application. Once you decide to ins…
- Fences for Horses (B 1192) Fences are necessary to safely confine horses yet provide them with the opportunity to exercise and graze. Because of the natural flight response of horses, they tend to injure themselves in fences more than most other livestock. In addition, many horses are extremely valuable and that justifies the extra cost of building a fence that is safe, strong and attractive. When selecting a fence, conside…

Field spinach production is labor intensive, and the cost of weed …
- How Wetlands Benefit Georgia Agriculture (B 1519) 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 man…
- Hurricane and Storm Damage to Greenhouse and Greenhouse Crops (TP 120) Hurricanes can cause severe damage to greenhouse structures and crops, both directly and indirectly. Strong winds, heavy rains, and flooding not only impact physical infrastructure, but also damage crops through exposure to extreme conditions.
