Most Florida citrus is grown on sandy soils which are extremely low in natural fertility. Such soils have so low an exchange capacity that they can retain only small amounts of applied exchangeable plant nutrients against the leachin action of rainfall. Other applied plant nutrients may be held in varying degrees of availability in the soil by other mechanisms. For These reasons, citrus trees must be fertilized with some elements abundantly and regularly and with others only infrequently to obtain high production of good quality fruit. Citrus will thrive under a wide range of nutrient revels, and it is impossible to outline a single fertilizer program that is best for all conditions. A wide variety of programs is now being used, and many result in high yields of good fruit. The program recommended here recognizes the existence of differences in grove conditions, including soils, rootstocks, scions, ages of trees, previous programs of fertilization, insect and disease control and other factors. |
