英文摘要 | Increasing demand for soil analysis prompted by environmental and economic factors has intensified the need for an inexpensive, fast, convenient and precise extraction. Current soil analysis procedures require several extractants which limit their use in many small commercial and residential applications. This paper reports the results of tests conducted with an innovative hot water extraction method to meet these needs in the soils of the arid Western United States. Hot water under pressure generated by commonly available espresso makers was used, with an appropriate proper soil/water ratio, to extract nitrate, potassium (K), sulfate, and phosphorus (P) in as many as 38 soils. The same extract was also used to measure pH. There were high and significant correlations when comparing standard soil analysis extraction methods and the hot water extraction for nitrate, sulfate, K, and P [r=0.99, 0.92, 0.85, and 0.60, respectively (p=0.001)]. The time of extraction varied with each soil, ranging from 0.3 minutes with a sandy soil to 4.5 minutes for a clay soil, and averaged 1.4 minutes. This extraction procedure coupled with available analytical equipment shows promise as an acceptable process for measuring nitrate, K, sulfate, P, and pH in soils. |
