Effect of Soil Moisture Tension and Physical Condition of Soil on Utilization of Water and Nutrients by Potatoes1

W. J. Flocker and Herman Timm2

A 3-year study was made of the effects of irrigation on the nutrient content of potato plants grown in differentially compacted soil Changes in soil moisture tension and in rates of fertilizer application affected the nutrient concentration in the plants more than did the degree of soil compaction. The amount of water, number of irrigations, and timing of applications depended upon the mean soil moisture tension and varied with degree of compaction. Irrigating at a mean soil moisture tension of 0.5 atmosphere provided the most efficient use of water and fertilizer, regardless of degree of compaction. The use of instruments to aid in timing irrigation was emphasized. Measurement of the mean soil moisture tension yielded data potentially useful for conserving both water and nitrogen.

1 This investigation was supported in part by Public Health Service grant FR-00009 from the Division of Research Facilities and Resources, National Institutes of Health. The authors appreciate the assistance of Mr. Ross Wight, former Laboratory Technician, and Dr. J. W. Riekels, former graduate assistant, in programming data for computer analysis. Presented in part before the American Society of Agronomy, Denver, Colorado, November 18–22, 196
