Field Experiments with Fertilizers. 319 



As soon as this work has been done apply broadcast the muriate of potash and 

 superphosphate to the whole of each plat which is to be manured with one or 

 the other, or with a mixture of the two, and drag into the soil as thoroughly as 

 possible. Drag the plats lengthwise because particular care must be taken that 

 none of the fertiUzer for one plat is sown on or is dragged on another plat 

 adjoining it. In many cases muriate of potash injures the plant if applied just 

 previous to putting in a crop; so that the earlier this fertilizer is applied in the 

 spring the less will be the danger of injury. 



Apply half the nitrate of soda broadcast on the whole of each plat requiring 

 it just before the seed is planted and drag into the soil. Three weeks later apply 

 the rest and cultivate in. 



Care should be taken to keep the nitrate off the foliage of plants, as it may 

 cause some damage; in the case of sown crops, such as oats, it will be impossible 

 to prevent this altogether. 



Be sure not to omit the blank ok check plat with no Fertilizer. 

 This is the most important of any single plat, because all of the others must be 

 compared with the blank in order to learn how much benefit the fertilizers have 

 been to the crop. 



You are to grow any crop you wish on these plats. 



The fame kind and same amount of seed is to be sown on each of the series of 

 nine plats in the set. It must be remembered that these experiments are to be 

 tried upon the crop planted and not upon an accidental crop of weeds. In no 

 case will the experiments be of value if the weeds are allowed to grow on the 

 plats. Thorough cultivation is one of the most important features of the field 

 test.
