irrigation and cultivation but not as a 

 substitute. There are many young trees 

 (rc-plants) in the old orchard. Often 

 these trees are badly neglected in that 

 they are growing in sod and receive no 

 clean cultivation. These conditions 

 should be remedied and here again ni- 

 trate can often be used to advantage. 



Trees just starting to bear must be 

 handled with considerable care. Often 

 they are making a very vigorous growth 

 and heavy fertilization and pruning will 

 retard the formation of spurs and pro- 

 duction of fruit. If the trees are making 

 a normal growth it is doubtful whether 

 the use of nitrate will be advisable. On 

 the other hand if trees are starling to 

 bear heavily and growth is but mod- 

 erate, the use of probably two pounds 

 nitrate per tree will be advisable. Such 

 trees as a rule have not yet been grow- 



ing in the presence of a shade crop 

 such as clover or alfalfa. 



Then there is the older orchard. In 

 most cases the grower has been using 

 nitrate of soda for a number of years. 

 The response from its use has been 

 very satisfactory in that greater yields 

 have been secured. Tree growth has 

 been much more satisfactory. In the 

 meantime, clover or alfalfa has been 

 grown and turned under. Such a prac- 

 tice is sufficient to furnish enough nitro- 

 gen for several crops if followed by 

 clean cultivation, assuming of course 

 that the soil is average and has not been 

 depleted of plant food by protracted 

 clean cultivation or intercrops. On the 

 poor sandy soil, more than one green 

 crop must be turned under to build up 

 a soil and provide sufficient humus. 



It should be pointed out that two tons

of alfalfa are capable of furnishing ap- 

 proximately 200 pounds of nitrogen, an 

 amount sufficient to grow a 500 box 

 crop of apples in addition to taking care 

 of tree growth. In most orchards alfalfa 

 does fairly well. That a great deal of 

 nitrogen, not formerly fixed in the soil 

 is now being secured from such a source 

 is quite evident. Trees growing under 

 such conditions make a normal growth 

 and produce well. 



Experiments with nitrate of soda were 

 made with trees growing in the presence 

 of alfalfa which had been seeded for 

 several years. Neither the alfalfa nor 

 the trees have ever been fertilized. The 

 use of nitrate of soda under such condi- 

 tions during the year when a heavy 

 crop of apples was borne did not in- 

 crease yields or improve the quality of

Dow Powdered 



Lead Arsenate 



Extremely light and fluffy — Dow Pow- 

 dered Lead Arsenate possesses many 

 advantages over the heavier and more 

 granular varieties. It mixes so readily 

 and remains so well in suspension that 

 it entirely covers foliage with a milky, 

 filmy coating. Because it reaches and 

 covers every part of foliage and branch 

 — because it sticks where it touches 

 and because of its high content of as- 

 senic. it has a deadly effect on all forms 

 of foliage eating pests. Dow Powdered 

 Lead Arsenate is a great economy and 

 a great convenience. Managers of large 

 orchards and directors of state stations 

 have used this product for years and 

 now purchase in carload lots. 



Packed in %, 1, 5, 10, 25, 50, 100 and
