be fertilized if overall growth or survival is poor or if plants do not 

 appear healthy. In general, only areas of poor plant growth will re- 

 quire fertilization. During the third growing season, fertilizer can be 

 applied as required to encourage growth. However, s^a oats is not re- 

 sponsive to fertilizer after the second season. 



2. Replanting . 



Areas of total plant mortality or localized areas with less than 10- 

 percent survival must be replanted. A planting with 20-percent survival 

 (50-percent for European beachgrass in the Pacific Northwest) should re- 

 quire only localized replanting if reasonably uniform. Ideally, a winter 

 planting with poor survival should be replanted as soon as possible-- late 

 spring or summer if soil conditions permit, or not later than the follow- 

 ing winter. 



VIII. LABOR REQUIREMENTS 



The approximate number of man-hours required to harvest, process, 

 and plant 1 acre (50- by 875-foot plot) is given in Table 3.
