8. Partial Seeding f y* ^bj 



. 



In regeneration by partial seeding the seed is distributed at 

 intervals over the area to be stocked. The cover is removed and 

 the soil worked only in the particular places where the seed is 

 sown. When the site is clean and the soil loose, little or no prep- 

 aration is required. On sites that require a clearance of the cover 

 and the working of the soil, much less labor is required than in 

 full seeding.
