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.

Soil acidity is one of the most important soil factors affecting crop growth and ultimately, yield and profitability. It is determined by measuring the soil pH, which is a measure of the amount of hydrogen ions in the soil solution. As soil acidity increases, the soil pH decreases. Soils tend to be naturally acidic in areas where rainfall is sufficient to cause substantial leaching of basic ions (such as calcium and magnesium), which are replaced by hydrogen ions. Most soils in Kentucky are naturally acidic because of our abundant rainfall.
The most important part of making fertilizer recommendations is collecting a good, representative soil sample. Soil test results and fertilizer recommendations are based solely on the few ounces of soil submitted to the laboratory for analysis. These few ounces can represent several million pounds of soil in the field. If this sample does not reflect actual soil conditions, the results can be misleading and lead to costly over- or under-fertilization. It is necessary to make sure that the soil sample sent to the laboratory accurately represents the area sampled.
