6 SOILS IN THE VICINITY OF BRUNSWICK, GA. 



ten days is sufficient, while five days is generally sufficient for celery 

 intended for cold storage. A few outside leaves are removed, the 

 plants packed, in the rough, directly into crates of standard size and 

 placed in iced cars. 



Celery is shipped mainly to eastern markets at any time between 

 Christmas and May, depending on time of planting and rate of 

 growth. March is the heavy shipping month for the Sanford district. 



There is considerable variation in the amount, quality, and method 

 of applying fertilizers. Some apply one-half before planting, follow- 

 ing with one or two later applications. Sodium nitrate or dried 

 blood is frequently used for the later applications, the former being 

 used in from one to three applications of about 200 pounds per acre 

 each. Castor pomace, cotton-seed meal, kainit, sulphate of potash, 

 tankage, dried blood, phosphoric acid, bone meal, etc., are variously 

 used by different growers, while a number of ready-mixed brands 

 are popular. An average analysis of fertilizers used would show 

 about 6 per cent phosphoric acid, 4 per cent nitrogen, and 7 per 

 cent potash. A frequent acreage application consists of 1 ton of 

 hardwood ashes (which is said to start the crop off well), 1 ton 

 cotton-seed meal or castor pomace, 1 ton high-grade "blood and 

 bone," 300 pounds sulphate of potash, 5 to 20 tons of well-rotted 

 manure (thoroughly rotted by stacking), and from 200 to 500 pounds 

 of sodium nitrate. 



The acreage application of fertilizer ranges from about 1 to 4 tons, 

 not including barnyard manure. Rich hammock land or mucky 

 soil requires less fertilization than the sandy land. The plan in this 

 section is to put on enough fertilizer to meet all possible needs of a crop. 

 No careful experiments have been made to determine the exact effect 

 of various materials or mixtures, or the best quantity to use, the 

 growers being satisfied with the good crops secured under present 

 methods of heavy though somewhat indiscriminate fertilization. It 

 seems to be pretty well established that liberal quantities of nitrogen 

 and potash are required and that the sulphate of potash is decidedly 

 better than kainit. Potash is believed to make celery stand shipment 

 better. 



Combinations giving the best growth of celery, according to test 

 made by the Florida Agricultural Experiment Station (1908 report), 

 were as follows, in order of rank: 



(1) Acid phosphate, dried blood, and low-grade sulphate of potash. 



(2) Floats, dried blood, and low-grade sulphate of potash. 



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



(4) Floats, nitrate of soda, and low-grade sulphate of potash.
