Can mid-infrared diffuse reflectance analysis predict nutrient and micronutrient concentration in soils? locations
Aims

To test mid infrared analysis to estimate micronutrient concentrations in soils.

Key messages
  • Fifty alkaline cropping soils form southern Australia were sampled and analysed for micronutrients.
  • Mid infrared spectra for eahc soil was also obtained and partial least squared regression used to estimate micronutrient content.
  • Very good correlations wbetween MIR and measured micronutrient concentrations and offfers an attactive alternative to traditional techniques.
