Automated Soil Pore Water Sampling and Nitrate Detection System

Abstract

Researchers at the University of California, Davis have developed a sophisticated soil nitrate sensing system designed to accurately measure soil pore water nitrate concentrations, enhancing sustainable agriculture and environmental monitoring.

Full Description

This technology encompasses a comprehensive soil nitrate sensing system that integrates a suction lysimeter, a soil moisture sensor, a spectrometer, and a controller. The system measures soil moisture, acquires soil pore water samples based on this estimation, and uses a spectrometer to accurately measure nitrate concentrations in these samples, facilitating precision agricultural practices and environmental monitoring.

Applications

• Agricultural fields for optimized fertilizer application. 
• Environmental monitoring to track nitrate movement and prevent pollution of groundwater and surface water sources. 
• Advanced research in soil science, agronomy, environmental science, and hydrology. 
• Smart farming solutions integrating data analytics for soil management.

Features/Benefits

• Accurately estimates and measures soil nitrate levels. 
• Integrates a suction lysimeter with multiple probes for water sampling from diverse locations. 
• Uses a spectrometer, including UV-Vis, for broad spectrum analysis. 
• Minimizes the effects of Dissolved Organic Carbon on nitrate measurements. 
• Computer-implemented methods for real-time data processing and analysis. 
• Improves accuracy in real-time soil nitrate measurement, crucial for optimal fertilizer application. 
• Reduces environmental impact by minimizing fertilizer leaching and pollution. 
• Enhances agricultural productivity through precision soil management and fertilizer management. 
• Addresses the lack of real-time soil nitrate level monitoring.
