Scatter Manure on Fields 



Remove manure and other farm waste every day and scatter it on 

 fields wherever practical. A manure spreader is useful. Spread tin- 

 material rather thin, so that any fly eggs or young maggots present 

 will be killed by heat, cold, or drying. 



Store Manure in Pits or Ricks 



Where it is impractical to scatter manure every day, store it in 

 fly-tight boxes or pits. They should be made preferably of concrete. 

 Put the manure into the container promptly, and keep the doors closed 

 when not in use. Place fly traps over holes in the top of the pit. 



For storing large quantities of manure, pile the loads in rectangular 

 stacks, or ricks. Make these ricks wide enough for the wagon ,or truck 

 to drive over the top to dump and pack down the manure as each 

 load is brought in. They may be as long as is necessary to hold all

the manure. Make the sides as nearly vertical as possible and pack 

 them with a shovel. If possible, make a concrete base for the rick; 

 dig a ditch around it, and pour crude oil in the ditch. The heat 

 generated in the manure will kill many maggots and drive the rest 

 to the surface. Many will drop into the ditch and be killed. 



Treat Manure With Chemicals 



Another way to prevent flies from breeding in manure is to treat it 

 with chemicals to kill the eggs and maggots. Borax is effective for 

 this purpose. Dissolve 11 ounces in about 5 gallons of water for each 

 8 bushels of manure. Sprinkle the solution on the manure after it has 

 been piled. Manure treated at this rate can later be used for fertilizer 

 if less than 15 tons per acre is applied. Heavier applications may 

 injure some crops. 



A mixture of two common fertilizers, calcium cyanamide and super- 

 phosphate, in equal parts will also greatly reduce fly breeding in 

 manure. Scatter this mixture dry over the manure at the rate of 1 

 pound to each bushel, and then sprinkle thoroughly with water.
