A Rapid In-Field Soil Extraction Procedure to Measure Plant-Available Soil P and K Using an ISFET Multi-Sensor
Background
Knowledge of plant-available soil nutrients is important for determining fertilizer requirements. Collecting this data rapidly and directly in the field could be beneficial for improving nutrient utilization efficiency.
Aim
Evaluation of the comparability of plant-available soil phosphorus (Ppa) and potassium (Kpa) measurements with a newly developed rapid soil extraction procedure based on a nutrient measurement system using an ISFET (ion-sensitive field-effect transistor) multi-sensor module (“FieldLab”) under quasi-realistic field conditions with the results of a lab-based soil analysis.
Methods
Following calibration of the FieldLab measurement system with the calcium-acetate-lactate (CAL) extraction method commonly used in Germany, the ability of the ISFET multi-sensor module to measure Ppa and Kpa under in-field conditions was investigated. For this purpose, a set of dried soil samples from 15 fields in northwest Germany was used, representing very different soil nutrient levels as well as various soil texture and soil organic matter contents. The soils were assessed using the standard lab procedure or the rapid FieldLab extraction, followed by lab measurements or nutrient quantification with the ISFET multi-sensor, respectively.
Results
Soil extraction using the FieldLab procedure showed a high correlation with the lab results (R2 0.97 and 0.92 for Ppa and Kpa, respectively). The combination of the rapid soil extraction followed by the ISFET measurement revealed significant correlations with the laboratory data (R2 0.80 and 0.79 for Ppa and Kpa, respectively).
Conclusion
The developed ISFET-based FieldLab procedure is an innovative and reliable approach for rapid in-field nutrient analysis of Ppa and Kpa, and it has the potential to enable the timely calculation of P and K fertilizer recommendations.
期刊介绍:
Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years.
Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH.
