•Soil microbial PLFAs and 16S RNA measured across 12 NEON ecoclimates.•MIR spectra predicted certain PLFAs, bacterial abundance and diversity with r2 > 0.6.•Prediction accuracy varied for different NEON ecoclimates.•Spatial patterns of microbial properties could be distinguished using MIR spectra...
