13 Ιαν 2022 · These two broad-spectrum soil tests have improved soil testing; have contributed to increased insights into the physical, chemical, and biological characteristics of soil; and have thereby led to more sustainable soil management and cropping systems.
26 Ιουν 2022 · Highlights. Spectroscopy is reliable because it is a highly repeatable and reproducible analytical technique. Spectra are calibrated to estimate concentrations of soil properties with known error. Spectroscopy is cost-effective for estimating soil properties.
In short, soil testing provides the critical information required to ensure all crop nutrition decisions are accurate, efficient, cost-effective and responsible. Soil analysis provides fundamental knowledge on the chemical, physical and biological status of a soil.
20 Μαρ 2019 · Soil and imaging spectroscopy, based on visible–near-infrared and shortwave infrared (400–2500 nm) spectral reflectance, has been shown to be a proven method for the quantitative prediction of key soil surface properties.
