10-10 even though peaches do not require P 

 after planting. 



To develop a nutrient-management plan for 

 your orchard rather than appl3dng pre-mixed 

 standard or orchard fertilizers, you should 

 consider the points mentioned above. Also, 

 realize that different nutrient sources are 

 available (Table 4). Also be aware of 

 environmental hazards and monetary loss 

 when overapplying nutrients. Remember, too, 

 that some nutrients can be toxic when levels 

 become too high (for example, boron). After 

 considering all the above, factor in cost. It may 

 cost a little more to apply what's required, but 

 in the long run, the financial cost may balance 

 out, and side effects such as environmental 

 pollution, toxicity, etc. will be avoided. 



Using the information presented in this 

 series of articles should help you formulate a 

 nutrient management program that makes 

 efficient use of inputs for maximum effect on 

 your crop.
