Here, again, with an entirely different method and with a different 

 crop, the fertilizer requirements are shown to be almost the same as 

 indicated by the plot work. The effect of lime is not so marked as in 

 the other experiment, but wheat does not require so great an amount of 

 lime as do the clovers. Manure was equally as important in this work 

 as in that already cited, and the fertilizing elements arranged them- 

 selves in the same order, that is, there was a greater need of nitrogen 

 and of phosphatic fertilizers than of potash. 



GENERAL NOTES ON LIME 



Forms of lime. — The form in which the lime is applied to the soil 

 seems to be a matter of choice, as the indications are that equal parts 

 of calcium, which is the element that is desired, seem to have about 

 the same effect on crops no matter in what form applied. 



Lime may be purchased in several forms: 

 (i) Quick-lime or unslaked lime. 



(2) Ground quick-lime. 



(3) Water-slaked lime or hydrated lime. 



(4) Ground limestone.
