Land judging is a way of appraising the physical nature and capability of soils. Certain soil properties, such as slope, depth, and color, that can be seen, felt, or measured, are reliable indicators of soil characteristics that impact crop growth and productivity. Land judging does not replace soil testing. Laboratory tests that determine the chemical and physical nature of soil help us predict plant response to lime and fertilizer, estimate the amount of a waste product that can be safely applied to the soil, and determine the limitations for uses such as homesites and roads.

Market preparation of burley and dark tobacco involves removing cured tobacco from the curing facilities (takedown), removing the stalks from the stick (bulking), removing cured leaves from tobacco stalks (stripping) and packaging for the market (baling). These processes can only be performed when cured leaves are sufficiently pliable to avoid breakage.

Pastures for sheep and goats are fertilized to ensure a reliable supply of energy, protein, and other nutrients for a long season of grazing. Management of plant nutrients maintains a balance of improved grasses and legumes and improves forage species competitiveness with many pasture weeds. The most important part of obtaining fertilizer recommendations is collecting a representative soil sample to send to the lab.

There has been recent interest from tobacco dealers in purchasing Connecticut Broadleaf tobacco produced in Kentucky and Tennessee. Connecticut Broadleaf has traditionally been grown in areas of the Connecticut River Valley in Connecticut and Massachusetts. However, decreased production in this area along with increased demand for natural leaf cigar wrappers has caused tobacco dealers to pursue other tobacco-producing areas for this type. At first glance, Connecticut Broadleaf tobacco resembles dark air-cured tobacco, but generally has enhanced leaf quality characteristics that can increase its potential value for use as cigar binders and wrappers.

Hemp is grown for fiber, grain, and cannabinoid extraction in Asia, Europe, and the Americas. Until recently, Cannabis sativa has been classified as a Schedule 1 controlled substance in the US. The Agricultural Act of 2014 (Farm Bill) allowed for reintroduction of industrial hemp under a pilot research program. Acreage increases and addition of state legislation resulted in over 78,000 acres of hemp grown in 23 states by the end of 2018. Hemp became a legal commodity under the 2018 Farm Bill, and by the end of 2019, over 500,000 licensed acres were documented across 45 states. Canada re-introduced the crop in 1998, and in 2018, almost 78,000 acres of hemp were licensed and planted.

Management of resistance to fungicides is based on alternating the use of particular modes of action, or FRAC groups, which essentially presents multiple different challenges to the fungal population. Overall, fungi that are naturally resistant to a mode of action are very rare in the environment. Challenging a population with multiple different modes of action will reduce the chance of developing widespread resistance, which will prolong the efficacy of these chemicals.

The number of fungicides that are registered for use on tobacco in Kentucky is relatively small in comparison to the large array of products available to producers of other crops. Although growers have a limited number of fungicides from which to choose, those that are available are effective against most of the major diseases of roots, stems, and foliage.

Historically, between-row cultivation for weed control has been an integral part of tobacco production. In one season, a grower might perform five or more cultivations and several hand weeding operations for adequate weed control. Early herbicide chemistries would control some weeds, but not all, forcing the producer to cultivate and hand weed. The development of better herbicides improved the range of weeds controlled, sometimes to the point that cultivation for weed control was not warranted. Many producers are so accustomed to cultivating they have forgotten why cultivation was necessary. The decision to cultivate should largely be based on the presence of weeds, but there are exceptions.

Historically, tobacco producers have relied heavily on surface tillage to prepare fields for transplanting. This study was established to determine how soil penetrometer resistance and burley tobacco yields were influenced by surface and subsurface tillage (subsoiling) on soils with no known compaction present.

This safety bulletin is intended to offer introductory safety training to tobacco workers in conjunction with a farm walk-around. It was written as if you and your workers are standing in or around the object currently being discussed, e.g., a tractor, with you or a designated assistant pointing out the various safety issues listed in the bulletin. It is not meant to be used as a stand-alone bulletin, especially just in a room, unless you have already gone through the walk-around and are reviewing points or having a discussion. It must be used out by the barn, equipment, or other subject being discussed.
