The effect of soil temperature and P fertilizer reaction in soil on P uptake by corn was studied in a growth chamber for 3 weeks. In the first week, medium temperature (24 C) and high temeprature (32 C) increased the number of lateral roots as compared to low temperature (16 C). Increased reaction under the influence of higher temperature did not limit the P uptake.
