corn at the last cultivation, but in orchards it is ordinarily 

 sown from the nrddle of July to the middle of August in 

 the North, on a well-prepared seed-bed, and is then lightly 

 dragged in. In old orchards, six quarts to the acre is 

 sufficient seed; in the open lands, about eight quarts is 

 the quantity required. 



Other plants are used as cover now and then or in 

 particular regions, as alfalfa, velvet bean and beggarweed 

 in the South, soybean, oats (mostly in mixture), cabbage. 

 In the North, the soybean should be sown early and tilled 

 for a time. Alfalfa is sometimes used as a cover in orchards 

 (as in Fig. 24, from the Lewiston-Clarkson region). If 

 irrigation is available, it may be an acceptable crop for 

 providing abundant herbage to plow under. Under usual 

 conditions, it is likely to be kept too long on the land. 



Paddock gives chemical analyses of cover-crop plants, 

 showing also date of seeding and taking samples, yields 

 of green crops and air-dry roots to the acre :

 thi& is therefore, not air-dry weight.
