 300 to 600 sulphate of potash ; or 

 3,000 to 6,000 wood ashes. 



Avoid the use of such potash compounds as muriate of potash and kainite 

 which contain chlorine. The sulphate of potash and also the carbonate which 

 is contained in wood ashes are very desirable as sources of potash for the fertili- 

 zation of tobacco soils.

200 to 400 muriate of potash ; or 



200 to 400 sulphate of potash ; or 



800 to 1.600 kainite ; or 



2,000 to 4,000 wood ashes. 



or 



For early tomatoes, quick-acting forms of plant-food should be used. Many 

 times it is best apply the nitrate of soda in two or three partial applications. 



For late tomatoes, slow-acting forms of plant-food may be used with good 

 results. 



Turnips. — Fertilizers same as for rape. 



Vetch.- — Fertilizers same as for beans. 



Watermelons. — Fertilizers same as for cucumbers.
