It looks like common salt and contains about 16per cent of nitrogen that is perfectly soluble and in form mostavailable for the plant. On this account only very small quan-tities should be applied at one time, because if not taken upby the plant it may be washed deep into the soil out of reachof the roots. It is especially desirable for early leaf crops suchas early spinach, cabbage and lettuce, and to apply when a cropcomes to a standstill. It acts with wonderful quickness—almostlike magic. It may be applied several times to the growingcrop at intervals of two weeks, using from 75 to 100 pounds peracre at each application. It may be sown near the hills if ap-plied to cabbage, but for spinach or similar crops it should be. Figure 2. —Spinach plants grown on land rich in rotten stable manure.

If it sticks to the leaves it is liable to burn sown during a hard rain it is quickly dissolved and washedto the roots of the plants without injury to the leaves. It isexpensive and should never be used when a cheaper supply ofnitrogenous manure will do just as well. It may occasionally beused to good advantage in water at the rate of one-half anounce of nitrate of soda to one gallon of water. Such a solutionwill not injure the foliage and is of sufficient strength. The use of very large quantities of nitrate of soda on theland has been found to make it necessary to continue using itin large quantit
