Summary
| Description |
English: Chesapeake Bay Foundation Clagett Farm welcomes U.S. Department of Agriculture (USDA) Agricultural Outlook Forum (AOF) Farm Conservation Tour participants and gives them an overview of Clagett Farm and the conservation practices that have been implemented in partnership with Natural Resource Conservation Service (NRCS) in Upper Marlboro, Maryland, on Feb. 21, 2018. The foundation and NRCS staff will discuss the implementation process of conservation plans that address soil health, drainage solutions and farm road designs. U.S. Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) District of Columbia, Delaware, Maryland State Soil Scientist Phillip King demonstrates the deployment of the Olympus Delta Professional XRF hand-held device that determines the amount of metal contaminants within the soil. The contaminants of concern are lead, mercury, cadmium and arsenic. Once identified, a land owner can choose not to use the land or address the problem with a remedial activity.
This technology provides an efficient and timely analysis for the customer so that they can make their land use decisions. Previously, aerial surveys and excavations were needed to get soil samples that were sent to laboratories for analysis. The increased use of surburban/urban interfaces for agricultural production is one of the reasons this device was brought into service is to detect metal content in soil that people may have put on the land. USDA Departmental Administration Radiation Safety Division Specialist Katina Jones, red shirt, takes advantage of the nearby XRF device demonstration to get some field measurements of natural radiation in the area and then near the device in various modes. No problems were detected.

La fondation et le personnel du NRCS discuteront du processus de mise en œuvre des plans de conservation qui traitent de la santé des sols, des solutions de drainage et de la conception des routes agricoles. Département américain de l'agriculture (USDA) Service de conservation des ressources naturelles (NRCS) District de Columbia, Delaware, État du Maryland Le pédologue Phillip King démontre le déploiement de l'appareil portatif Olympus Delta Professional XRF qui détermine la quantité de contaminants métalliques dans le sol. Les contaminants préoccupants sont le plomb, le mercure, le cadmium et l'arsenic. Une fois identifié, un propriétaire foncier peut choisir de ne pas utiliser le terrain ou de résoudre le problème avec une activité corrective. Cette technologie fournit une analyse efficace et rapide au client afin qu'il puisse prendre ses décisions en matière d'utilisation des terres. Auparavant, des levés aériens et des fouilles étaient nécessaires pour obtenir des échantillons de sol qui étaient envoyés aux laboratoires pour analyse. L'utilisation accrue des interfaces périurbain/urbain pour la production agricole est l'une des raisons pour lesquelles cet appareil a été mis en service pour détecter la teneur en métaux dans le sol que les gens ont pu mettre sur le terrain. La spécialiste de la division de la radioprotection de l'administration départementale de l'USDA, Katina Jones, chemise rouge, profite de la démonstration de l'appareil XRF à proximité pour obtenir des mesures sur le terrain du rayonnement naturel dans la zone, puis à proximité de l'appareil dans différents modes. ici, aucun problème n'a été détecté.
