Fertilization is an important practice of maintaining plant health. The blueberry plant is no exception, but there are important considerations when fertilizing blueberries. The rates, timing, and type of fertilizer should be common knowledge for the grower. In this circular, how to fertilize blueberry plants is described with text, diagrams, and calculations to provide growers, Extension agents, and anyone interested with the knowledge to successfully grow blueberries, from newly established to mature plantings. This publication was written to address commercial growers’ need for a reference to avoid costly mistakes such as over-fertilization, discussing both granular and liquid fertilization.

Haiti Peanut Research Report
This report summarizes the findings of field trials and basic data collected in Haiti under the Feed the Future Peanut & Mycotoxin Innovation Lab project from 2014-2017. The focus of the research was to improve peanut productivity through management options for foliar diseases, low soil fertility, and other yield-limiting agronomic factors.

Drip, trickle, microemitters, and subsurface irrigation systems are considered low-volume irrigation. Low-volume irrigation systems are designed to improve irrigation efficiency, delivering water to the crop accurately with minimal water loss. Irrigation efficiency can be categorized into two main concepts: water loss and uniform application. If water loss is significant, or application uniformity is poor, efficiency will be low. Generally, the most significant loss of irrigation water is from overwatering, where the water percolates below the root zone, or from runoff. With good management, losses due to leaks, system drainage, and flushing of filters and lateral lines should not exceed 1%. Low-volume systems have the opportunity to achieve efficiency, and under careful management, will minimize losses from overirrigation. However, using low-volume systems requires increased irrigation frequency and soil moisture monitoring should be used to improve water-use efficiency. This publication covers system design, system efficiencies, components, chemical applications, diseases related to irrigation, and soil moisture monitoring.

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 companies.
This bulletin discusses what farmers need to know about producing cover crops organically and gives example enterprise budgets for cereal rye and crimson clover. A two-year on-farm trial indicated that producing organic cover crop seed may be profitable.

Experimental power determinations are very important to agriculture and other applied sciences. It is necessary to be able to detect
small differences when human and animal health or production profitability are in question. Yet textbooks on biostatistics for
agriculturalists generally barely introduce the subject of how to design an experiment to detect some important difference between
treatments. To come to meaningful conclusions, researchers need to know how to plan both plan and conduct experiments. Entirely different
questions may be asked of an experiment depending on who is to interpret the results. Developers may be most interested in showing
that their new product gives responses not statistically significantly different from some standard. Potential consumers, on the other
hand, should be more interested in demonstrating that expected responses from a new product are equal to the standard|

Private forest owners control most of the southern forest resource and are critical to maintaining forest health in the South. Record droughts, rising temperatures, increased frequency and intensity of wildfires, insect and plant invasions, and more intense storm events all pose threats to the health of Southern forests. Scientists project that increases in temperature and changes in rainfall patterns will cause these disturbances to become more common, occurring with greater intensity or duration. This pamphlet reviews healthy forest strategies and approaches to decrease the risks associated with these disturbances on your forestland.

Littleleaf disease is a forest health concern for several pine species in the southeastern United States. This disease is a particular problem for shortleaf pine (Pinus echinata Mill.) and is one reason why this species is less widely planted compared with other pines. Littleleaf disease results from a combination of biological factors and site characteristics, when combined with a susceptible host tree. Some factors are more important – i.e., they have a primary role in disease formation – while others have a secondary role, and mostly contribute to making disease symptoms worse.

Southern Regional Extension ForestryResearch and development on alternative sources of energy has been a priority for the United States since volatile energy prices in the 1970’s. This period of time, known as the “Energy Crisis,” occurred due to an oil embargo and limited global supply of oil. To combat these problems, Congress passed the Emergency Petroleum Act in 1973, the Energy Policy and Conservation Act in 1975, and created the Department of Energy in 1977. These congressional acts from more than 30 years ago were the beginnings of a national interest towards developing alternative energy sources. The outcome has been support for research and development of non-petroleum energy sources such as biomass, which is a renewable and carbon neutral source of energy used for heat, electricity and transportation fuels.

Four species of Ips bark beetles (also commonly known as Ips engraver beetles or Ips beetles) occur throughout pure and mixed pine forests in the southeastern U.S.: the six-spined ips (Ips calligraphus), the pine engraver (Ips pini), the eastern five-spined ips (Ips grandicollis), and the small southern pine engraver (Ips avulsus). Ips beetles appear similar to other bark beetles in this region, including the southern pine beetle (SPB), black turpentine beetle, and red turpentine beetle. These beetles occur throughout the entire southeastern U.S., with the exception of the pine engraver and red turpentine beetle, which are found only in the Appalachian region.
