Precision agriculture is crucial for securing food supplies for the world’s expanding population. This research focuses on the critical role of nutrient assessment in data-driven agriculture, specifically targeting phosphorus (P) concentrations. Traditional soil testing methods are often expensive and time-consuming, posing challenges for continuous cropping systems. To address this, a novel chip-level colorimeter for real-time, portable detection of soil P levels is developed. The device operates by inducing a chemical reaction with the soil solution, generating a color change in the presence of nutrients. This color change is quantitatively measured using sensors integrated into a handheld colorimeter or spectrophotometer. Test samples of various standard phosphate solutions were analyzed and validated against laboratory spectrophotometric results. The developed device demonstrates significant potential for environmental and biological applications, offering a cost-effective and efficient solution for maintaining soil fertility and enhancing crop yields. This innovation represents a crucial advancement in smart agriculture, paving the way for sustainable agricultural practices.

摘要

Precision agriculture is crucial for securing food supplies for the world’s expanding population. This research focuses on the critical role of nutrient assessment in data-driven agriculture, specifically targeting phosphorus (P) concentrations. Traditional soil testing methods are often expensive and time-consuming, posing challenges for continuous cropping systems. To address this, a novel chip-level colorimeter for real-time, portable detection of soil P levels is developed. The device operates by inducing a chemical reaction with the soil solution, generating a color change in the presence of nutrients. This color change is quantitatively measured using sensors integrated into a handheld colorimeter or spectrophotometer. Test samples of various standard phosphate solutions were analyzed and validated against laboratory spectrophotometric results. The developed device demonstrates significant potential for environmental and biological applications, offering a cost-effective and efficient solution for maintaining soil fertility and enhancing crop yields.
