The use of silicon (Si) in agriculture is gaining worldwide attention because of the benefits plants gain from its absorption while its application fits in well with the concept of sustainable agriculture. One of the difficulties inherent to Si research is the measure of biogenic Si in biologically heterogeneous material. The few techniques available are digestion-based techniques that are hazardous and time-consuming, fastidious, expensive and particularly in the case of Si, suffer from low accuracy due to incomplete solubilization and potential volatilization. In recent reports, portable X-ray fluorescence spectrometers (P-XRF) have been shown to offer precise nonconsumptive analysis of multiple elements, including those known to be difficult to measure such as Si, in large numbers of samples. This equipment overcomes many of the problems related to Si measurements, including sample digestion, and offers many advantages such as versatility, ease of use, cost and time reduction that will render any research lab interested in elemental analysis in plant and soil samples more efficient and productive.

硅（Si）在农业中的应用正受到全世界的关注，因为植物从其吸收中获得了好处，而它的应用也符合可持续农业的概念。硅研究固有的困难之一是测量生物非均质材料中的生物硅。可用的几种技术是基于消化的技术，这种技术危险且耗时，繁琐，昂贵，特别是在Si的情况下，由于不完全溶解和潜在的挥发，准确性较低。在最近的报告中，便携式x射线荧光光谱仪（P-XRF）已被证明可以对大量样品中的多种元素进行精确的非消耗性分析，包括那些已知难以测量的元素，如Si。该设备克服了许多与Si测量相关的问题，包括样品消化，并提供了许多优点，如多功能性，易用性，成本和时间的减少，这将使任何对植物和土壤样品元素分析感兴趣的研究实验室更高效和富有成效。
