SUCCESSFUL FARMING 



manure is based on the average farm price of the crops produced. It is 

 also evident from the table that stall manure gave in every instance a 

 ■larger return per ton than did yard manure, and that floats and acid phos- 

 phate proved by all odds the best reinforcing materials. While acid 

 phosphate reinforcement gave the largest return per ton of manure, the 

 floats proved about equally profitable from the investment standpoint. 



In localities where phosphorus is the dominant soil requirement, the 

 reinforcement of manure with acid phosphate at the rate of about forty 

 pounds to each ton of manure is a most excellent practice. The manner 

 of applying the phosphate may be determined by conditions. It will 

 frequent ly be found convenient to apply this material to the manure in

the stalls or stables each day at the rate of about one pound for each 

 fully grown cow, horse or steer, and in lesser amounts for the smaller 

 animals. There is probably no place in which the raw rock phosphate 

 is likely to give better results than when used in this way as a reinforce- 

 ment to manure. 



Economical Use of Manure. — The most economical use of manure 

 involves a number of factors. It is the opinion of both chemists and 

 farmers that manure and urine should be applied to the soil in its fresh- 

 est possible condition. If this is true, manure should be hauled from the 

 stable or barnyard to the field as soon as it is made. As previously indi- 

 cated, this method reduces to the minimum the cost of handling and has 

 several additional advantages. Well-rotted manure may be more quickly 

 available to plants, less bulky and easier to distribute, and weight for
