Farmers' Bulletin

Pages : 570
Book Description
"Corn is made mostly of soil moisture and warm air. The acre yield of the United States has been below 31 bushels every year, while moisture and warm air sufficient to bring the yield to 100 bushels have gone to waste. By reducing the waste of moisture and heat corn yields can be doubled. Moisture runs off and carries with it the most fertile parts of the soil. Heat goes to waste in drying the soil and subsoil while timely cultivation would save both heat and moisture. Cultivation sometimes is beneficial, sometime injurious. Page 18. Recent discovery of the fact that seed corn that matures well and dries out promptly will keep its good germinating and yielding powers for four or five years makes unnecessary planting of poor seed corn or the loss of acclimated and improved strains. Page 23. This bulletin is especially applicable to dry-land regions; but corn yields are so dependent upon the relative quantities of soil moisture and heat that the principles given here apply wherever corn is raised." -- p. [2]
