土壤健康是决定全球农业系统可持续性和自然生态系统稳定性的关键因素之一。微生物分解活动在土壤健康中起着重要作用;获得对这一属性的时空见解对于理解土壤功能以及管理土壤以确保农业供应，阻止生物多样性丧失和减缓气候变化至关重要。在这里，提出了一种新型的原位电子土壤分解传感器，该传感器依赖于利用生物聚合物聚（3-羟基丁酸酯-co-3-羟基戊酸酯）作为粘合剂的印刷导电复合材料迹线的降解。这种材料选择性地响应微生物活性环境，具有连续变化的电阻信号，可以很容易地用低成本电子设备进行仪表化，以实现广泛的空间分布。在土壤中，传感器的响应和微生物分解活动的强度之间的相关性进行观察和量化的呼吸速率超过14天的比较，显示设备响应可预测的静态条件和扰动一般分解活动。提出了一种新型的原位电子土壤分解传感器，该传感器依赖于利用生物聚合物作为粘合剂的印刷导电复合迹线的降解。在堆肥茶和土壤中，传感器响应和微生物分解活性之间的相关性被观察和量化，表明设备可预测地响应于静态条件和一般分解活性的扰动。
Soil health is one of the key factors in determining the sustainability of global agricultural systems and the stability of natural ecosystems. Microbial decomposition activity plays an important role in soil health; and gaining spatiotemporal insights into this attribute is critical for understanding soil function as well as for managing soils to ensure agricultural supply, stem biodiversity loss, and mitigate climate change. Here, a novel in situ electronic soil decomposition sensor that relies on the degradation of a printed conductive composite trace utilizing the biopolymer poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) as a binder is presented. This material responds selectively to microbially active environments with a continuously varying resistive signal that can be readily instrumented with low‐cost electronics to enable wide spatial distribution. In soil, a correlation between sensor response and intensity of microbial decomposition activity is observed and quantified by comparison with respiration rates over 14 days, showing that devices respond predictably to both static conditions and perturbations in general decomposition activity. A novel in situ electronic soil decomposition sensor that relies on the degradation of a printed conductive composite trace utilizing a biopolymer as a binder is presented. In compost tea and soil, a correlation between sensor response and microbial decomposition activity is observed and quantified, showing that devices respond predictably to both static conditions and perturbations in general decomposition activity.
