Sulfur nutrition requirements of peach trees Academic Article uri icon


  • Changes in fertilizer and pesticide formulations plus success in reducing sulfur (S) emissions to the air from industrial operations have reduced the availability of S to peach trees in some locations. Peach (Prunus persica L. Batsch) trees on highly leached acid sands have shown responses to S fertilization. The levels of total S required for S sufficiency is important to determine fertilizer needs. The 100 ppm S04-S requirement offered by some sources has been misinterpreted. Greenhouse experiments with Nemaguard, Lovell, Montclar and Nemared rootstock seedlings resulted in the establishment of levels representing S deficiency and sufficiency. The foliage and growth rates of rootstock seedlings in this experiment showed severe deficiency symptoms at 550-990 g S g-1DW. Sufficiency was achieved at 1400-2500 g S g-1DW.
