<br /> The importance of the secondary and mino olements cannot be over
<br /> plants need them badly as they need
<br /> the primary elements, nitrogen, phosphorus nd potash. That they are being, or have been, depleted from the soils is evi•
<br /> denced by the fact that they are being given to animals In salt blocks or feed supplements; being added to vitamin pills or
<br /> in tonics; added to bread and milk, i
<br /> FUNCTION OF PLANT FOODS What Is pH?
<br /> IRON is directly connected with the functioning of chlorophyll. no pH scale is a chemist's yardstick used to measure the acidity
<br /> A lack of iron contributes to chlorosis which causes a yellow, or alkalinity of soil. It is your plant food thermometer, A pH above 7

<br /> SULFUR is a most important element of the lant. It is utilized is alkaline; below 7 is acid,

<br /> tcins, vitamins, etc,; has a direct bearing on water movement in points on the pH scale, plant foods go quickly into solution, while at
<br /> the plant, and on chlorophyll production. It also is an aid to other points these plant foods lock up" into soluble or "inedible" forms,
