50 Forestry Quarterly 



Oberforster Ehrlich describes his practice 



Fertilizer in establishing a permanent 3 acre trial 



in nursery. A compost heap is made by 



Nurseries mixing good humus soil free from roots 



with layers of unslacked lime ( i liter lime 

 to I cbm. soil). Each year for 3 years this heap is spaded over 

 two or three times during the summer. In three years the com- 

 post is ready for use. After the ground is spaded, a mixture of 

 8 kg Kainit and 4 kg Thomas slag per are is sprinkled over the 

 area and worked in with the hoe. After 3 to 4 days yellow lupine 

 is sown, (2 kg per are). These are plowed under when the pods 

 begin to form and the ground is left in furrows over winter. 

 Next spring 1.5-2 cbm compost are applied. This three-fold 

 fertilizing is as far as possible applied every three years. Broad- 

 leaf seedlings are further manured twice, beginning of May and 

 end of June, with altogether 2 kg Chili saltpetre per are, brought 

 under 4 to 5 cm, and a similar treatment is applied in the fall 

 with a mixture of 8 kg Kainit and 4 kg of Thomas slag ; with 

 such treatment oaks made shoots i m long. The time of applica- 

 tion is chosen accordingly to the nature of the fertilizer, saltpetre 

 being effective at once, Kainit requiring time and containing 

 chloric salts that are injurious to roots and must first be absorbed 

 by the soil.

At the seed cleaning station at Annaburg, 

 Collecting near Halle, a long series of experiments 



Seed. has been carried out by Haack, to deter- 



mine to what extent Scotch pine seed suf- 

 fered from high temperature and drying. From the detailed de- 

 scription of the precautions taken, and the difficulties met and 

 solved it is evident that the greatest care has been exercised 

 throughout and the severest criticism of his own methods em- 

 ployed by the author, so that his results are unassailable. Tests 

 are recorded for some eighty thousand seeds. 



As preliminary it was first determined that Scotch pine seed 

 were ripe November ist and capable then of immediate germina- 

 tion, showing quite as high germination per cent, as seeds from 

 cones remaining on the trees until dry in March. In the drying
