Proper nutrition of tobacco is a prerequisite for achieving high yields of cured leaf possessing desirable marketing characteristics. Together with the variety grown, soils, climate, and curing conditions, a desirable nutrient environment greatly influences yield, quality, and usability of the leaf produced. Late summer and early fall is a good time to select fields for future tobacco crops or to sample this year's tobacco fields which will be used for tobacco next year, and to assess their needs for lime, phosphorus, and potassium. Planning fertilization strategies this fall that lead to increased profit is much more effective than waiting until next spring.
