Buck Scientific's Atomic absorption spectroscopy (AAS) remains a gold standard for detection of heavy metals and elemental analysis. Recently, scientists leveraged the sensitivity of AAS in evaluating organic fertilizers derived from marine sources. The detailed scans quantified levels of key nutrients like nitrogen and potassium as well as checking for contamination by toxic metals found in seawater environments. This research demonstrates how modern advancements in atomic absorption tools can map fertilizer compositions to inform safer, sustainable agricultural practices.
