EOTATION OF CROPS. 213

 excellent crop to precede the root on rich soils : —

Here again wheat was the gi-eat and important crop. 



The advantages gained for the wheat are so great 

 that the temptation for planting it cannot be resisted, 

 ^one of the above combinations can, we consider, be 

 exact, as experience has taught that rye is better to 

 precede the beet, as the quantity of manure required 

 for its cultivation is less than for wheat. The portions 

 of the manure still remaining in the ground after the 

 harvesting will have less effect upon the beet crops 

 that immediately follow. 



We do not recommend any particular rotation, as 

 before stated. This must greatly vary, but, suffice it to 

 say, that many small crops, such as colza, flax, barley, 

 etc., should be utilized, as their elements enter into 

 direct consumption in the feeding of the animals of the 

 farm, and should consequently be planted proportionally 

 to their demand.^ 



In the United States Indian corn is grown to so gi'eat 

 an extent, and forms so profitable a crop, that it also 

 should take a prominent part in the rotation. 



' If A'' be the number of animals and C the consumption of a given element, 

 the total consumed will \ie C ')<. N. If ^ is the yield in pounds or bushels to the
