Precipitation in Pennsylvania averages about 37 inches each year. About 13 inches of this precipitation runs off land into streams, while 24 inches infiltrates into the soil, where it can be used by crops. The 24 inches of precipitation usually is sufficient for growing many agronomic and some horticultural crops. However, irrigation often is necessary because of the uneven distribution of precipitation throughout the year, especially during critical growth periods.
The purpose of this book is to provide the best and most up-to-date information available for commercial vegetable growers in the southeastern US: Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, Texas, Tennessee, South Carolina and Virginia. These recommendations are suggested guidelines for production in the above states. Factors such as markets, weather, and location may warrant modifications and/or different practices or planting dates not specifically mentioned in this book.
This bulletin presents the framework for the nutrient recommendations for vegetable crops given in the new MSU nutrient recommendation program. A subsequent bulletin will provide more management information to complement basic details of the recommendations for individual crops.
