FERTILIZER RECOMMENDATIONS FOR BUNCH AND MUSCADINE GRAPES
IN REGIONS OF FLORIDA

J. A. Mortensen and M. C. Halbrooks


Fertilization in the Vineyard

Recommendations given here are grouped according to region and type of
grape. The soils of Central Florida are sandy with low organic matter thus
fertilizer recommendations for these soils include higher nitrogen (N) and
lower phosphorus (P) than those for the clayey soils of North and West
Florida. The soils of North and West Florida have a higher cation exchange
capacity (CEC) which causes less N to be leached and more of the added P to be
fixed (made unavailable to plant roots for uptake). Thus N applications can
be made less frequently and in smaller amounts while extra P must be applied
to insure that some of the added P remains unfixed and available for plant
uptake. In Central Florida, N applications must be made more frequently
throughout the growing season in order to insure some N is always available
for plant uptake due to the rapid leaching which occurs in these soils. The
two forms of nitrogen, nitrate (NO ) and ammonium (NH4 ), which plants can
take up and utilize for growth differ greatly in the rate at which they are
leached from the soil. Nitrate, as an anion, is not retained by the
predominantly negatively charged soil colloids thus is subject to rapid
leaching. Therefore recommendations are to use a fertilizer which can provide
at least 50% of the total N needs as ammonium on the deep sands of Central
Florida. Finally, with the long post harvest and pre-dormant period in
Central Florida, a post harvest application of fertilizer is recommended to
promote good growth the following spring. This is not possible in North and
West Florida because it would discourage early dormancy which is important to
avoid frost damage. Tables 1 through 4 give the fertilizer programs
recommended for standard dry fertilizer mixes.

Where fertilization is done through the irrigation system use completely
soluble materials and apply as recommended nJ.rQceedring&.asjthe-.First Greater
