土壤脲酶(S-UE)能够水解尿素,产生氨和碳酸。土壤脲酶活性与土壤的微生物数量、有机物质含量、全氮和速效氮含量呈正相关。土壤脲酶活性反应了土壤的氮素状况。该产品提供了一种简单、方便、快速的S-UE活性检测方法,适用于土壤样本,其检测原理是利用靛酚蓝比色法测定脲酶水解尿素产生的NH₃-N。
Soil urease (S-UE) hydrolyzes urea to produce ammonia and carbonic acid. Soil urease activity is positively correlated with soil microbial biomass, organic matter content, total nitrogen, and available nitrogen content, reflecting the nitrogen status of the soil. This product provides a simple, convenient, and rapid method for detecting S-UE activity in soil samples, based on the indophenol blue colorimetric method to measure the NH₃-N produced by urea hydrolysis.
