For many years after the discovery of the two stable isotopes of boron (B,B) in 1920 they were not used as tracers in the soil-plant system due to analytical constraints. However, with the advent of inductively coupled plasma mass spectrometry in the early 1980s, it became possible to measure precisely the natural variations of the B isotopes in biological systems. Nevertheless, up to the present time there is very little information in the literature on B variations in soils, plants, fertilizers and foodstuffs. Therefore, information on the potential of B as a tracer of B dynamics in natural- and agro-ecosystems remains limited. The relative abundance of the boron isotope ( B) in soils, plants and nutrient sources, and applications of variations in the natural abundance of B as a tracer of anthropogenic sources of nitrate contamination of water and the provenance of agricultural products are reviewed.
1920年发现硼的两种稳定同位素（¹⁰B、¹¹B）后的许多年里，由于分析上的限制，它们并未被用作土壤 - 植物系统中的示踪剂。然而，随着20世纪80年代初电感耦合等离子体质谱仪的出现，精确测量生物系统中硼同位素的自然变化成为可能。尽管如此，目前文献中关于土壤、植物、肥料和食品中硼变化的信息非常少。因此，关于硼作为自然和农业生态系统中硼动态示踪剂潜力的信息仍然有限。本文综述了土壤、植物和养分源中硼同位素（¹¹B）的相对丰度，以及硼自然丰度变化作为水体硝酸盐污染人为来源和农产品来源示踪剂的应用。
