MANURES AND HUMUS IN SOIL. 163 



use of the succeeding alfalfa in any case. Acid phos- 

 phate works well with crimson clover; put on 200 

 pounds of it per acre, choosing always a grade 

 analyzing a good percentage of available phosphoric 

 acid. It likes a good seed bed too. Mix with 

 it 10 per cent of alfalfa, and if the land has never 

 had on it either alfalfa or crimson clover, get some 

 infected earth from an old field of each of the plants. 



Infecting a Field. — One can use rather a small 

 amount of earth and get good results in inoculat- 

 ing a field if he does it in the right manner. Let 

 him get as little as 100 pounds of earth from where 

 crimson clover has been grown and 50 pounds of 

 earth from an alfalfa field or a sweet clover patch 

 and mix these together and pulverize them well. Do 

 this away from the sun. Then mix the crimson 

 clover seed, say 15 pounds and say 2 pounds of 

 alfalfa seed with the 150 pounds of infected soil. 

 Sow this altogether on an acre of land. Sow it 

 if you can late in the day, or at any event follow 

 the sower with a harrow that will at once stir the 

 land and cover seed and infected soil. Sunlight is 

 fatal to inoculation. 



The result will be that both sorts of plants will 

 grow well together and the alfalfa plants, while 

 much more feeble in growth than the crimson clover, 

 will yet hold its own pretty bravely and will be- 

 come inoculated and thus will prepare the land for 

 a single seeding of alfalfa next year.
