the soil conditions necessary for the manufacture, 

 maintenance and proper distribution of that food to the 

 plants as they need it. 



Botanists tell us that every part of the plant has 

 functions which it performs for its own development. 

 The functioning of the various organs of the plant is 

 naturally very different from that of the animal, never- 

 theless, these organs are just as important to the plant 

 as the digestive and breathing organs are to the animal. 

 The greatest of care is exercised in feeding the stock. 

 The proper amount of food and water is given to the 

 animals at the right time. In the summer the green 

 pastures supply the great percentage of food for cows. 

 In the winter they are given foods which produce milk 

 and flesh. If horses are being used in the field they are 

 fed the kind of food that keeps them strong and healthy. 

 The same rule holds true of the entire animal family. 

 No two types of animals ever receive the same kind of 

 food nor even the same portion; that has to be given 

 according to their kind. The same feeding law holds 

 true of plants. 



Plant life is different from animal life. The animal 

 is either fed by human hands or goes about searching 

 its own food. The plant is stationary. It, therefore, 

 must subsist upon the food contained in the air and 

 soil within reach of its organs. 



All crop producing plants have roots, stems, leaves, 

 and flowers, or the fruit. The farmer is concerned as 

 to the quality and quantity of fruit produced. The 

 quality and quantity of fruit are determined by the 

 growth of the leaf and stem, and also the plant's ability 

 to withstand the evil influences of wind, drouth and 

 excessive rainfall.
