For sandy soils, 3 to 4 sidedressings with 10-0'-20 are-recommended
 (see Table 3). These applications are needed because of the low exchange
 capacity (lack of electrical charges) which make nitrogen and potassium
 more vulnerable to losses from the soil. It is recommended that the
 first fertilization occur about March 15th and subsequent sidedressings
 be spaced from 4 to 6 weeks apart. Any application of nitrogen after
 August 1st will likely result in a reduction in sucrose content in
 sugarcane.

 B. Micronutrients

 Micronutrients (ie. minor elements or trace elements) are roanmmoana
 recommended for plant cane on organic soils and for both plant and
 stubble cane on sandy soils (Tables 1 and 2). Manganese availability
 decreases with increased soil pH, therefore, it is recommended when the
 soil pH is greater than 5.65 and not recommended for a pH of 5.65 or
 less. When planting cane on newly cleared land, apply broadcast, disc
 in, and plow under 300 pounds per acre of 0-0-30 containing 6.0% CuO
 and 3.0% ZnO in addition to the normal recommendation for plant cane
 grown on "old land".

 C. Sulfur

 Due to the high buffering capacity of organic soil, pH alteration
of the whole soil is difficult and costly. Sulfur applied in the
furrow can change the pH of the soil in the fertilizer band thereby
keeping manganese and other micronutrients available. Five hundred
pounds per acre are recommended for furrow application when the soil pH
is 6.5 or greater. When both fertilizer and sulfur are recommended,
the grower should contact his fertilizer dealer to see if a mix of
the two materials can be made, thus allowing fertilization and sulfur
application in one field operation. In event that a mix is obtained,
the rate should be adjusted accordingly so the recommended amounts
are applied.

D. Comparing Soil Test Results

 Caution should be taken in the comparison of soil tests results
from different laboratories as the methods may very likely be different.
For example the Everglades Experiment Station phosphorus test will
usually be considerably lower than those values from other labs where
stronger reagents are used. However, at this laboratory it has been
found that water extractable phosphorus is the soil fraction which best
correlates with plant response on these organic soils.
