WETEC

Soil Moisture & Nutrients Monitoring System

Multi-depth in-situ soil profile monitoring for agriculture, research, and environmental management in Singapore.

Soil Moisture & Nutrients

Irrigating by schedule and fertilising by season are educated guesses. Too much water leaches nutrients and drives up costs. Too little stresses roots and reduces yield. Over-fertilising pollutes, excess nitrogen and phosphorus run off into drains and waterways. Without continuous, in-situ soil data, decisions about when to water and when to fertilise are made on yesterday’s information.

In-situ soil monitoring systems deployable at single or multiple depths that measure the parameters that matters at the root zone, in real-time. Soil samplers provide the physical soil sample for lab analysis when total nutrient content, regulatory-grade results, or physical soil characterisation is required. Together they cover the full picture, each available at Wetec.

What You Can Measure

Wetec soil monitoring systems can be deployed at single or multiple depths to profile the soil column, configured around the parameters that matter for your application:

  • Soil moisture and physical — volumetric water content (VWC), temperature, and electrical conductivity (EC).

  • Soil chemistry — pH and redox potential (pH / ORP).

  • Nutrients — nitrogen, phosphorus, and potassium (NPK)

Where It Is Used

  • Precision irrigation and smart farming
  • Horticulture, nurseries, and protected cultivation
  • Turf and landscape management
  • Environmental monitoring and contaminated land
  • Soil science research

Frequently Asked Questions

In-situ NPK sensors provide relative measurements, suitable for tracking trends and changes over time. Lab analysis provides total nutrient content and is recommended alongside in-situ data for formal agronomic recommendations.
