• UF/IFAS fertilization and liming recommendations are advisory in nature and emphasize efficient fertilizer use and environmentally sound nutrient management without losses of yield or crop quality.
• It is assumed the nutrients will be supplied from purchased commercial fertilizer and the expected crop yields and quality will be typical of economically viable production.
• Growers should consider UF/IFAS recommendations in the context of their entire management strategy, such as return on investment in fertilizer and the benefits of applying organic soil amendments.

Fertilizer rates

Fertilizer application should include 15 to 20 lbs sulfur/ac.

Fertilizer timing and placement

• Apply all the P₂O₅, 30% of the K₂O, and 30 lbs N/A in a preplant or at-planting application.
• Four weeks after planting, sidedress the remaining 70% of the K₂O.
• Apply the remaining N in two or more sidedressings, one of which should be 4 weeks after planting.

Fertilizer sources

• Apply S as sulfate (e.g., gypsum, ammonium sulfate, magnesium sulfate, potassium sulfate, potassium magnesium sulfate), because elemental S will react too slowly to supply the sulfur needs of the current crop.

Water management

• Fertilizer and water management are linked. Maximum fertilizer efficiency is achieved only with close attention to water management. Supply only enough irrigation water to satisfy crop requirements. Excess irrigation may result in leaching of N and K, creating possible plant deficiencies.
