  • Soil Compaction Spectrum Technologies

    Why measure soil compaction? The soil is the plant’s reservoir of water, nutrients and oxygen. Compacted soil has less pore space to store what the plant needs. Soil compaction prevents moisture penetration, reduces fertilizer and chemical uptake, creates conditions for anaerobic microbes to build up and hinders plant root growth.
