Smart monitoring tools for organic matter, nutrients, and soil loss in agricultural systems
An integrated monitoring and modeling platform that uses autonomous sensors, real-time data transmission, and computational models to estimate soil, organic matter, and nutrient losses caused by water erosion. Designed to support more accurate and cost-effective crop management decisions, particularly fertilization strategies, based on continuous field measurements.
Overview
Soil degradation caused by water erosion reduces agricultural productivity by depleting soil particles, organic matter, and essential nutrients. This solution addresses that challenge by combining autonomous field instrumentation with data management and computational modeling to monitor and estimate soil losses in real time. The platform enables farmers, agronomists, and land managers to make better-informed decisions about crop system management, including fertilization and land conservation practices, based on continuous local measurements rather than periodic sampling.
The offering is being developed by AGROSAVIA, a Colombian agricultural research corporation with deep experience in generating applied scientific knowledge and transferring technology to producers. The work targets improved soil productivity and sustainability through precision agriculture approaches aligned with Agriculture 4.0 principles.
Technical specifications
Key features:
- Autonomous sensor network deployed in closed runoff plots to capture continuous precipitation and runoff data
- Real-time data transmission infrastructure based on Agriculture 4.0 concepts
- Big Data database storing meteorological and runoff information
- Web application for user consultation and data access
- Computational model trained to estimate organic matter and nutrient losses associated with individual storm events
- Decision-support outputs intended to guide fertilization and crop management interventions
Prior research by the team showed that preliminary soil loss models built with 32 rainfall events and basic climatic and crop variables achieved coefficients of determination below 0.5, confirming that continuous data is required to build a robust predictive model.
Technology readiness level
The project is currently in the development and validation phase. Three specific objectives guide the work: deploying a smart autonomous instrument network, building a Big Data-backed information management system with a web interface, and training an initial computational model for soil, organic matter, and nutrient loss estimation. The planned validation period is approximately one year, after which the modeling tools are expected to move toward broader field evaluation and potential adoption by agricultural producers and land management stakeholders.
About Corporación Colombiana de Investigación Agropecuaria
AGROSAVIA is a Colombian decentralized public entity of mixed non-profit participation dedicated to agricultural science, technology, and innovation. The organization focuses on generating scientific knowledge and developing agricultural technology through research, technological adaptation, and the dissemination of technical expertise. Its operations are organized into specialized innovation networks, including cacao, fruits, vegetables, livestock, permanent crops, and roots and tubers. By bridging the gap between advanced research and practical application, AGROSAVIA develops improved crop varieties, such as biofortified beans and sugarcane, and establishes integrated management protocols to enhance agricultural productivity and sustainability.
These efforts are vital for Colombian agricultural producers, providing them with the tools and knowledge necessary to improve competitiveness, ensure sustainable natural resource management, and raise their quality of life. Through initiatives like field schools and the provision of technical assistance, the corporation facilitates the transfer of technology and information to small-scale farmers. By fostering collaboration between the public and private sectors, AGROSAVIA acts as a key driver for technical change in the national agricultural sector, helping producers modernize their practices and address challenges related to climate resilience and food security.
