Alfalfa for New York 



1971 



The map herewith (Fig. 148) shows the State divided into four 

 principal soil areas, according to lime requirements for alfalfa. Where 

 the soil has been derived in general from a limestone formation, as in 

 section I, it usually will not be necessary to add more lime. The presence 



Fig. 148. — This chart is intended to show in a general way the variation in lime require- 

 ment for alfalfa in New York State. It must be borne in mind that the map is very general, 

 since there are considerable areas even in section III where lime is not required for alfalfa 

 culture. 



In general, th^ valleys require less lime than do th€ hills. This is quite true in section 

 I V, where most of the valleys have sufficient lime and most of the hills are deficient. Keep- 

 ing this in mind, the following statements will serve as a general guide in determining 

 the amount of lime to apply: 



Section I, generally enough lime, but where required about ^00 to 1000 pounds of quick- 

 lime per acre is sufficient. 



Section II. 1000 to 2000 pounds of quicklime per acre on hills and half as much in valleys. 



Section III, 2000 to 4000 pounds of quicklime per acre on hills and half as much in valleys. 



Section I]' is very irregular, ^fany local areas and most of the valleys have sufficient 

 lime, but hills in general will require about the same amount as do sections II and III 



of limestone pebbles or stones ordinarih- indicates sufficient lime, while 

 the absence of limestone pebbles usually, but not always, indicates the 

 need of lime. 



When lime is required, in section I generally from 500 to 1000 pounds of 

 quicklime per acre will b^ sufificient, pr tv^ice this amount of ground lirrj^^
