FIELD 0EOP8. 



The rotation of crops by seasons was as follows: Lupines, oats and serradella, oats 

 and clover, cloverj and clover. Both lime and mar] a1 the rate of 2,500 and 5,000 kg. 

 per hectare, respectively, proved very effective and highly profitable. The gross as 

 well as the nel returns were in favor of marl, and the use of lime in 2 applications 



gave better results than applying the entire quantity al > time. The yields of oats 



obtained were satisfactory. The method successfully employed for the reduction of 

 the heath soil Is described. 



Soiling- crops, 1904, <i. A. Billings New Jersey Staa. Rpt. 1904, /'/>■ •■• 

 ph. 4). — Bummer soiling was carried on this season from Maj li to October 20, 160 



days. 



A herd equivalent to 13 full-grown animals was supplied with roughage from a 

 continuous rotation of forage crops. The data show thai 221.89 tons were gro^ a al 

 a cost of 1429.21, oral an average of $1.93 per ton. The feeding and maun rial value 

 of the crops Is shown, and the data deducted indicate thai 46 tons of clover hay fur- 

 nished 1 1,316 U>s. of protein, 2, 1 16 lbs. of crude Eat, and 64,952 lbs. of carbohyd] 

 56 tons of mixed hay, 1 L,312 lbs. protein, 2,912 lbs. crude fat, and 77,168 lbs. carbo- 

 hydrates; and 227 tons of corn silage, 7,718 lbs. protein, 3,632 lbs. crude Eat, and 

 77. L80 li*-. carbohj drates. 



It is further shown that the total tonnage of soiling crops furnishes nitrogen equiva- 

 lent to 5.15 tons of nitrate of soda, phosphoric acid equivalent to 1. 11 tons of acid 



phosphate, and potash equivalent to 1.89 tons of muriate of potash, and that the 



manurial value of this crop is also equivalent to 9.9 ton- of barnyard manure, :;. in 



tons of nitrate of soda, and 0.98 ton of muriate of potash. A comparis f the 



manurial and feeding value, estimating barnyard manure at $1.50 per ton, nitrate of 

 soda at $45, and muriate of potash at $42, shows that the value of the Boiling crops 

 for green manure would he $331.86, or $97.35 less than the feeding value. 



Th.- rotation furnished a continuous supply of forage. The average yield per acre 

 for all the crop-, including alfalfa but not including mixed grasses, was 11.99 tons 

 per acre. It is pointed out that the protein produced by one acre of alfalfa yielding 

 17. ~> tons of green fodder is equivalent to the quantity of protein in 6.4 tons of clover 

 hay. or about 5 tons of wheal bran. ( m the average for t; years alfalfa yielded 19. L8 

 ton- per acre, equivalent to 72 tons of clover hay. according to the nutrients con- 

 tained in the L' crops. 



Of the different crops grown alfalfa was found to he the most economical. Barn- 

 yard millet, pearl millet, Thoroughbred White Flint corn, and Southern White 

 coin, being about equal in yield, ranked next to alfalfa in the average production of 

 forage. General notes on the different crops are given. The results of an experi- 

 ment in - ling alfalfa at different periods were decidedly in favor ol seeding 



between the 1st and the L5th of August. 



The inoculation experiments of the season gave results in favor of the cylinder not 

 inoculated. The results are not considered as showing that inoculation has been a 



failure, hut that the cylinders not inoculated obtained the alfalfa bacteria from some 

 source other than the use of a 80il solution or soil as applied in this experiment. The 

 application of a -oil infusion was much more effective than the use of the soil Itself. 

 Different kind- of -oil showed a variation of 74 per cent in responding to inoculation. 

 Freehold marl in Monmouth County being the least affected by inoculation, and 



\V Ibine sand in Cape May County making the greatest gains. Nitrate of sodaal 



the rate of 147 lbs. per acre, cost in- •-:;.. -;i , - S a\ e a lo— of i:;."> percent in favor of inoc- 

 ulation. 



I »f :; varieties of corn compared to ascertain their value \>>v silage Southern White 

 in rows:-; ft. apart ami at intervals of g in. in the drill gave the mosl satisfactory 



result-, both in respect to quality and quantity. The yield of this variety was 1 1.84 



tons per acre, while Hickory Kin- produced 7.8 tons, and Thoroughbred White Flint, 

 which was exceptionally good in quality, 8.77 tons.
