SIGNIFICANCE OF THE SOIL TO HUMAN DISEASE
The birth of hairless pigs has been caused experimentally by feeding brood sows diets low in iodine and has been prevented by supplying iodine compounds, seen immediately in the following generations; but, iron in mice takes effect in the fifth or sixth generation only. This shows at the same time that some of the deficiencies are transferred to thefollowing or later generations by nature —through the fertilization apparatus: the egg or spermatozoon— as there is no other way.
Familiar examples of the results of a deficiency of trace minerals are:
(a) Sand drawn of tobacco, due to magnesium deficiency if the soil contains less than 0.2% MgO.
(b) Chlorosis of tomatoes on Florida soils, which can be cured by manganese additions.
(c)The wilting of leaves in tobacco is caused by copper deficiency.
(d) Failure of cattle to develop normally is often due to deficiency of iron, copper or possibly cobalt in plants. (Iron directly connected to chlorophyll.)
(e) The abnormal accumulated occurrence of animal and human goitre in parts of Switzerland, Wisconsin, Minnesota and Washington is due to iodine deficiency.
(f)"Lame-sickness" of cattle in South Africa is due to deficiency of Ca. K. P. in leached areas.
(g) "Bush sickness" of sheep in New Zealand is due to lack
of cobalt. (h) Hairless pigs due to iodine deficiency. (i) In human beings some acute and chronic diseases are due to the following deficiencies:
Bad teeth, to K and Ca
Rickets, to Ca and P
Anemias, to copper and iron
Myedema and goitre, toiodine
Starvation edema, nephritic edema, cardiac edema, cardiorenal syndrome, old age (thyroid deficiency), etc., all more or less due to deficiency of several minerals
Skin and bone tuberculosis, to K. P. Ca, etc.

Overtiming is productive of chlorosis and with plants susceptible to iron—chlorosis—lime should be sparingly used.
Soil losses are generally brought about through cropping orerosion—mostly the losses are of N. P. K., less of Ca and magnesium. (See Table 1.) One such group of figures for a silty clay loam at Ithaca, N. Y., shows the average amount removed under a standard rotation (corn, oats, wheat, clover, timothy) to be as follows:
Nitrogen 60
Phosphorus 25
Potasium 50
Calcium 30
Magnesium 20
All various mineral and trace soil losses can best be restored bystable and human manure, except phosphorus. Once the original supply of P has been depleted, it must be replaced by chemical fertilizers in connection with manure for even the high P-content of guano, up to 12 per cent and even 20 to 25 per cent, is not sufficient. Thus, several authors assume that the East Coast may be a desert after 150 to 200 years if we do not help to prevent such continuingconditions as prevail today.
There are two familiar types of erosion—water and wind erosion. When man steps in and cultivates the land, he creates conditions that may result in an enormous acceleration of erosion. This is the most disastrous of the evil things that can happen to the soil. Forests must be considered the best defense against erosion and on steep slopes certain protection isnecessary.
Factors influencing the mineral composition of crops, according to C. A. Browne, are:158
1. Difference in soil (organic—bacterial)
(inorganic—pH)
2. Differences in cropping (time)
3. Variety of crop—rotation
4. Period of growth of crop—successive cuttings
5. Climate—sunshine—oxygen
6. Water supply
7. Kind of fertilizer-even ploughing under legumes (lupines)(We added: Cultural practices, environmental conditions and earthworms interpolating an intermediate metabolism. )
Natural manure exerts the best influence on crops: the Peruvian planter can raise 1,760 pounds of cotton per acre, using guano, compared with an average of less than 300 pounds in Louisiana and 390 in Egypt. Therefore, export of guano is no longer permitted in Peru.
