ESTABLISHING FORESTS BY DIRECT SEEDING 



217 



The cost of the removal of the cover and soil preparation is 

 influenced not only by the character of the cover and soil but also 

 by the form, size, and spacing of the seeded portions. In some 

 instances, particularly in seeding in strips, the cultivated places 

 over which the seed is scattered may occupy one-half of the 

 total area. On the other hand, where the regeneration is in 

 small seed spots spaced at 6-foot intervals the prepared and seeded 

 area is about one-twentieth of the total. 



The chief advantages of partial seeding over full seeding are as 

 follows : 



a. From one-half to one-eighth as much seed is required. 



6. No cultivation is required except on the areas where the seed 

 is sown. 



c. The best places can be selected for the seeding. 



d. The seed can be better covered.

9. METHODS OF PARTIAL SEEDING 



The places over which the seed is distributed in partial seeding 

 are of various forms and sizes and arranged in a variety of ways 

 (Fig. 39). They should be distributed as evenly as possible. 

 The more important methods of partial seeding are as follows: 



a. Seeding in strips. c. Seeding in spots. 



6. Seeding in lines. d. Dibbling or seeding in holes.
