As the results of this test are likely to vary somewhat with different 

 varieties, Russell's Big Boll seed were used at Edgecombe and King's 

 Improved 1 at Iredell. 



In Table XIV is presented a summary of four years' tests at Edge- 

 combe and six at Iredell. 



III. Fertilization and Cultivation of Corn and Cotton. 



corn. 



Culture. — It unquestionably pays well to thoroughly break and broad- 

 cast-harrow land for corn. Using a two-horse plow and running it 8 

 to 10 inches deep, and afterwards harrowing with large smoothing 

 harrow, puts the land in nice condition. It is also well to run a small- 

 tooth harrow or weeder across corn rows about the time the plants are 

 coming up, and even after they are several inches high, slanting the 

 teeth of the harrow backward. Harrowing in this way saves after- 

 cultivation, and is a quick and comparatively inexpensive way of getting 

 over the land. The land being thoroughly broken before the corn is 

 put in the ground, only shallow, level cultivation with some one of the 

 considerable number of good cultivators need be given the crop during 

 the growing season. The one-horse cultivators cover corn rows in two 

 or three furrows, and the two-horse ones at a single trip. The cultiva- 

 tion should be frequent — about every ten to twelve days — and, if pos- 

 sible, just after rains, so as to break any crust formed by showers, 

 leaving a dust mulch to retard the loss of moisture added to the soil 

 by previous rains. Toward the end of the growing season the culti- 

 vators should only be run one to one and a half inches deep, so as to 

 disturb as little as possible the roots of the plants, which, by that time, 

 are well into the middle of the rows. 



Fertilizers for Corn. — The experimental work on the sandy soils of 

 the east, reports of which have been made previously, has progressed 

 far enough, we feel, to draw some conclusions in reference to the best 

 amounts and proportions of nitrogen, phosphoric acid and potash for 

 corn. As the results of the past five years' work have not yet been 

 published, the following formulas, based on the results of the first two 

 years' tests, and tests in other States with similar soil and climatic 

 conditions, are given as good ones for corn: 



For Corn on Land in Fair Condition. 



No. 1— 



Acid phosphate, 14 per cent phosphoric acid 900 pounds 



Cotton-seed meal, 6.59 2 per cent nitrogen, 2.5 per cent phos- 

 phoric acid and 1.5 per cent potash 960 pounds 



Kainit, 12.5 per cent potash 140 pounds 



2,000 pounds 



This mixture will contain: available phosphoric acid, 7.5 per cent; 

 potash, 1.6 per cent; nitrogen, 3.2 per cent (equal to ammonia, 3.9 

 per cent). 



'Culpepper's Improved was used in the test of 1903. 

 ! 6.59 per cent nitrogen equals 8 per cent ammonia.
