as is possible with a two-horse plow. In this furrow 

 thoroughly decomposed compost of muck and stable 

 manure is scattered, at the rate of about a two-horse 

 wagon load to 100 feet of furrow. The soil and compost 

 are mixed thoroughly, gradually filling the furrow in doing 

 so. When well-rotted vegetable matter cannot be ob- 

 tained, humus may be supplied by sowing the field to a 

 rank-growing legume, such as velvet beans. Cowpeas 

 are not so desirable, since most varieties harbor the root- 

 knot — a very serious disease of celery in light sandy soils 

 of subtropical regions. 



Fertilizer for celery. 



The proportions of fertilizer ingredients should be as 

 follows : ammonia, 6 per cent ; available phosphoric acid, 

 6 per cent ; potash, 8 per cent. Use 2000 pounds or more 

 to the acre. The growers in Florida use from two to three 

 tons. If the celery is planted on muckland, the amount of 

 nitrogen should be reduced. 



The following fertilizer ingredients will give the propor- 

 tions of the above formula at the rate of 2000 pounds to 

 the acre :
