<br />At 5 em the curves for both treatments fluctuate more than for <br />other depths indicating the sensitivity of the surface to changes in <br />solar radiation. Of the tvo treatments, the topsoiled plot appears to <br />be the most affected by changing radiation loads. The topsoiled treat- <br />meat is also varmer throughout July and August at this depth and <br />maintains higher temperatures into October. Sy October 28 the temper- <br />atures for both treatments essentially converge vith little differences. <br />The ~*~=mum temperatures, recorded on July 26, are 105°F for the refuse <br />treatment and 110°F for the topsoiled treatment. <br />Through May and into July the temperatures of the topsoiled plot <br />are generally a fev degrees varmer than for the refuse plot at the <br />15 cm depth. Through August, September, and October this difference <br />decreases and the temperatures become nearly equal. On June 28 the <br />surface air temperature dropped sharply. Sae temperature of the top- <br />, soiled treatment dropped a fev degrees belov that of the refuse treatment. <br />This observation indicates that the topsoiled treatment profile fluctu- <br />ates greatly vith changing surface temperatures. Maximum temperatures <br />for the refuse treatment (95°F) and topsoiled treatment (98°F) vets <br />recorded on July 26. <br />L <br />At 25 ® the temperatures of the topsoiled treatment are slightly <br />warmer thaw the refuse treatment. In September the temperatures for <br />the tvo treatments com~erge and remain essentially equal until the <br />` cad of the sampling period. <br />The curves for the two treatments closely approximate each other <br />at the 50 ® depth with the exception of the anomaly in the topsoiled <br />treatment on September 2. From September 2 until the cad of the sampling <br />period the 50 cm readings for both treatments were slightly varmer than <br />the 25 ® readings. <br />_. 25 <br />
