Soil Temperature Patterns in Surface-Insulated Containers in Water Baths Related to Maize Behavior1

  1. John M. Walker2

Abstract

Abstract

Different soil surface insulators did not establish isothermal conditions in soil in metal containers placed in constant temperature water baths. The water temperatures were 15, 25, and 35C, with the air temperature about 25C. The behavior of maize (Zea mays L.) seedlings, which were grown in these soils, was related to the degree of temperature control by the various insulators. Differences in growth and ion uptake were statistically significant when the water bath temperatures were not optimum at 15 and 35C.
