Lime has been used to less advantage in Emmet and Cheboygan coun- 

 ties. Experiments conducted on sandy soils with light to medium 

 heavy subsoils in Emmet and Cheboygan counties show, as an average 

 of three fields where lime was applied at the rate of 2 tons to the acre, 

 an increase of 1.9 bushels of rye but none in case of the straw. Lime did 

 not affect the growth of the 1920 spring seeding of sweet clover and al- 

 falfa on these projects. It is very doubtful if lime can be used economic- 

 ally on these special types of soil. 



Experiments conducted on the Manistee county farm near Manistee 

 and on the farm of Thomas Moore near Thompsonville, indicate that 

 lime may be used with profit in this section. The soils are rather light 

 sands on open sandy subsoils. In each case 2.5 tons of lime were applied 

 in Ihe fall of 1919. On the county farm the lime increased the yield of

rye 4.52 bushels per acre and resulted in an excellent stand of alfalfa 

 that was seeded with the rye. Alfalfa seeded on the untreated land 

 was a failure. On the farm of Mr. Moore the limed plot yielded 7.99 

 bushels more rye per acre than the unlimed portion of the field. In this 

 case the increased yield of rye the first year of the rotation paid for the 

 cost of the lime and left a profit of 73 cents per acre. 



BARNYARD MANURE. 



Experiments are being carried on to determine the value of barnyard 

 manure. At the Van Buren county farm near Hartford 10 tons of 

 manure were applied in the spring of 1917. The soil in question is a 

 poor sandy loam. The manure increased the yield of the oat crop 14.6 

 bushels of grain and 284 pounds of straw. Clover showed a slight gain 

 of 44 pounds per acre. From the two crops the gross returns amount 

 to 110.41 per acre. 



Other experiments on the farm of John Wheeting near Imlay City 

 are in progress. The soil is a sand underlaid by a sand silt subsoil
