How was kudzu introduced to Kentucky?

Kudzu was considered to be a good bankholder against erosion, a good cover crop between plantings, and a good soil builder. For kudzu is a legume, which are the nitrogen fixers of the plant world. Nitrogen fixing bacteria, nematodes and plants turn nitrogen that's present in the soil, but unavailable to plants, into soluble nitrogen. For nitrogen must be soluble, to be taken up as the water and nutrients that roots need to send up to shoots, for photosynthesis. Plants need 16-17 nutrients for growth and survival. And nitrogen is in the top most needed of those nutrients. For these reasons, the Civilian Conservation Corps planted kudzu along highways in the Southern States. Also during the depression of the 1930s, the Soil Conservation Service paid farmers $8.00 for every acre that was planted with the purported aesthetic, environmentally friendly plant. And key newspapers and key nurseries promoted the plant's use.
