5OO VEGETABLE GARDENING 



fertilizers will be needed for a typical truck farm of 100 

 acres to supply the nearest city market? Problems in 

 companion and succession cropping and rotation are ex- 

 ceedingly valuable. Work of this character may consti- 

 tute a part of the laboratory practice, although most of 

 it should be done between class periods. 



706. Definite lines of work. As the character of the 

 work undertaken will vary exceedingly in various local- 

 ities, the following notes must be regarded as merely 

 suggestive. 



CHAPTER III, SOILS. If there are different soil types 

 in the community they should be inspected, if possible, 

 to determine their adaptability for garden crops. 



CHAPTER IV, TILLAGE AND TILLAGE TOOLS. (i) Plow 

 part of the garden plat in the fall and the remainder 

 early in the spring. Note the difference in the moisture 

 supply and in other physical properties. (2) Study the 

 various types of tools on the premises or at local supply 

 houses. (3) If possible, make an actual test of the im- 

 portant types of hand and horse implements. 



CHAPTER V, STABLE MANURES. (i) Make applications 

 of various classes of manure for a few important vege- 

 tables. Demonstrations with fresh and rotten manure 

 should prove especially valuable. (2) Make a compost 

 pile of manures and other materials if available. 



CHAPTER VI, GREEN MANURES AND COVER CROPS. 

 Study the character and extent of top and root growth 

 of different classes of green manures and cover crops 

 growing in the vicinity. 



CHAPTER VII, COMMERCIAL FERTILIZERS. (i) Deter- 

 mine the fertilizer requirement of the plat to be planted. 

 (2) Each student should mix and apply the materials 

 which have been determined for his particular plat. (3) 

 Apply nitrate of soda at different stages of growth. 

 Various methods of application may also be tested.
