SOILS IN THE VICINITY OF BRUNSWICK, GA. 7 



All points considered, including yield, resistance to disease, etc., 

 the following combinations, in order of rank, gave best results: 



(1) Bone meal, fish scrap, and high-grade sulphate of potash. 



(2) Bone meal, fish scrap, and muriate of potash. 



(3) Bone meal, dried blood, and high-grade sulphate of potash. 



(4) Floats, fish scrap, and low-grade sulphate of potash. 



(5) Acid phosphate, dried blood, and muriate of potash. 



The tendency of these tests was to show that where nitrate of soda 

 and kainit are used the plants are more susceptible to blackheart, that 

 bone meal is the best source of phosphoric acid, and that dried blood 

 and fish scrap are the best sources of nitrogen. 



Spraying with Bordeaux mixture is very effective in combating 

 blight. Much less trouble, however, comes from this source than 

 blackheart, the greater or less prevalence of which seems to depend, 

 to a certain extent at least, upon the kind of fertilizer used. There 

 has been little trouble from other diseases. 



Not infrequently celery is planted with lettuce, but this method 

 is not considered the best by many growers, as the latter crop is 

 sometimes given too much water in the heavy subirrigation given the 

 later-set celery. The better plan seems to be to follow lettuce with 

 celery, in which case less fertilization is needed, as the residual 

 effect of that applied to the former is of considerable account. 

 Relatively less potash is required for lettuce, a 5-5-5 brand being 

 frequently used. About the same materials, however, are used for 

 both crops, but the proportions are varied and the acreage applica- 

 tion for lettuce is only about half that used for celery. A number 

 of farmers disk under cowpeas during summer for succeeding crops 

 of celery and lettuce with excellent results. 



Good crops of Irish potatoes, tomatoes, and eggplant are secured 

 after celery and heavy yields of crab-grass hay. Cauliflower, Ber- 

 muda onions, and cabbage are also grown successfully on subirrigated 

 lands. 



For subirrigation 2 or 3 inch tiles laid 15, 20, or 25 feet apart at a 

 depth of about 12 or 18 inches are connected with a main placed 

 along the higher part of the field, into which water from artesian 

 wells flows. The connections are made by a small iron pipe and at 

 these junctions "standpipes" or large tile drains are set upright 

 and connected with the mains so that water connection with the 

 laterals may be controlled with ease. These openings are also con- 

 venient for dipping out water to be used on freshly set plants. It 

 is estimated that a 2-inch artesian well will furnish sufficient water 

 to subirrigate a 5-acre field. 



The deep sandy land in the vicinity of Brunswick, such as the 

 Amelia sand, on account of its open nature, will require surface irri- 

 gation probably by spraying from pipes carried through the fields.
