PURDUE UNIVERSITY Agricultural Experiment Station Circular No. 66 LaFayette, Ind., August, 1917 S. D. Conner THE LIME AND FERTILIZER NEEDS OF INDIANA SOILS SUMMARY 1. Indiana soils have been so exhaustively cropped for so many years that they are much less productive than they should be. 2. The principal losses which have been sustained by Indiana soils are in the organic matter and nitrogen supply. 3. Available phosphoric acid and potash have been depleted. 4. Over three-fourths of the soils of Indiana are acid. 5. To increase and maintain the nitrogen and organic matter supply in soils, more legumes must be grown. 6. To have success with legumes on acid soils, it is necessary to use some form of lime, such as pulverized limestone, one to four tons to the acre. 7. Available phosphate is needed on practically all acid soils, with or without limestone. One hundred fifty to 300 pounds to the acre, of high grade acid phosphate have proven most profitable on Indiana soils. 8. Potash fertilization has proven profitable on some soils. Neutral or slightly acid muck and black sand soils need potash, particularly for corn. 9. The bulk of the nitrogen should be supplied through legumes and manure. On light colored soils which have been heavily cropped, some nitrogen in the fertilizer is profitable for wheat. 10. Crop residues and manures should be carefully conserved. The farmer who does this will need to buy little or no nitrogen and potash in fertilizers for general crops. THE LIME AND FERTILIZER NEEDS OF INDIANA SOILS The average soil of Indiana does not produce more than half as much as it is capable of producing. The production of greater yields per acre depends upon a number of factors, such as drainage, rotation. tillage, seed, sanitation and fertilization. Some of these factors depend upon the expenditure of much labor per acre, and in view of the present labor situation, the farmer should not be charged with undue negligence on this score. A man is not a good farmer, however, if he does not practice methods of management and soil
