Soil Enzymatic Activity Reader

The Soil Enzymatic Activity Reader (SEAR), also known as "BOB," is a breakthrough portable diagnostic tool developed by Digit Soil. It offers farmers and researchers a professional-grade, laboratory-independent solution for near real-time soil soil biological activity assessment.

The SEAR Offer: Key Benefits

• Instant On-Site Data: Eliminates the need for the transport, and 2-4 week wait times by providing results in within an hour. Anyone can measure!

• Functional Biology Assessment: Unlike standard chemical tests that measure static nutrient concentrations (N-P-K), SEAR quantifies the activity of extracellular enzymes—how fast are the nutrients in soil being released.

• Actionable Fertilization Insights: Converts complex enzymatic data into precise recommendations via an integrated app, helping to optimize both organic and synthetic fertilizer timing and dosage - see fertilization advice service offer.

• Evidence-Based biostimulation: Enables biostimulant and soil enhancer companies to provide quantifiable proof of their product's efficacy by measuring immediate spikes in soil biological activity.

Technical Specifications

• Measurement Principle: Utilizes specialized Reaction Plates containing fluorogenic substrates.

• Enzymes Monitored: Simultaneously assesses key enzymes responsible for carbon, nitrogen, and phosphorus cycling, including:

  • beta-Glucosidase (Carbon cycling)

  • Leucine aminopeptidase (Nitrogen cycling)

  • Phosphatase (Phosphorus cycling)

  • beta-Xylosidase

  • N-acetylglucosaminidase

• Environmental Versatility: Robust performance across diverse soil textures, ranging from acid forest soils (pH < 4) to silty clay loam and high organic carbon agricultural soils.

• Data Integration: Features locally tailored digital twin models and satellite Earth Observation data to create smart, field-centric fertilization plans -- see fertilisation advice service
