Datasense and GT5000 Terra – From smart agriculture data to practical benefits
Our customer Datasense uses Gasmet’s GT5000 Terra multi-gas analyzer in smart agriculture research, aiming to improve yields and reduce emissions by optimizing the amount and timing of fertilization.
The role of optimal fertilizer amount: Good yield, low emissions
In agriculture, fertilization affects everything: too much increases nitrous oxide and methane emissions, too little weakens yields. Datasense, together with fertilizer manufacturers, studies the optimal amount of fertilizer under different conditions so that plants utilize nitrogen efficiently and environmental impact remains manageable.
When inputs are optimized for growth, yields improve and fields remain competitive under various conditions.
Research results provide valuable information for fertilizer manufacturers’ product development and practical benefits for farmers. Lower emissions and better carbon cycling are reflected in everyday life as more responsible farming.
Yara project: Research and practical benefits
A recent Datasense research project was Yara Finland’s two-year project, which studied how the timing and splitting of nitrogen fertilization affect greenhouse gas emissions and carbon sequestration. Datasense was responsible for the project’s technology and analysis services, combining data and research with practical farming.
Fertilizer research has clarified, among other things:
- Growth optimization: Maximum yield with minimal emissions.
- Fertilizer amount optimization: Savings in work time and fuel costs. Fewer passes mean less unnecessary soil compaction and manageable tractor climate load.
- Understanding soil respiration and gas dynamics: Measurements verify CO₂ emissions and the effects of nitrogen cycling on the field ecosystem.
- Carbon sequestration: Studies show how cultivation methods affect carbon cycling and climate-friendliness.
Nitrous oxide (N₂O) emissions were measured with Gasmet’s gas analyzer frequently throughout the growing season.
Studies show a clear connection: as emissions decrease, yield improves. The GT5000 Terra gas analyzer is a key tool in verifying this.
GT5000 Terra brings accuracy and reliability to research
The Gasmet GT5000 Terra analyzer operates in conjunction with Datasense’s own commercial chamber system, as well as a multiplexer and other measuring devices. The GT5000 Terra simultaneously measures several gases (nitrous oxide, methane, and carbon dioxide) from the soil surface.
According to Datasense’s experience, measurements with the gas analyzer are more accurate than those with conventional sensors, and the device verifies the effects of emission reduction.
Especially in N₂O research, changes in concentrations cannot be detected except with an analyzer. Additionally, the simultaneous detection of all gases is essential.
Thanks to Gasmet’s solution, Datasense has been able to deliver concrete benefits to both farmers and fertilizer manufacturers.
The GT5000 Terra is designed for field use, and Datasense’s research has shown that it is easy to carry. The GT5000 Terra provides precise measurements directly from the field, which facilitates decision-making.
A clear user interface ensures consistent results regardless of the operator.
Datasense CEO Jari Hakkarainen says that Gasmet’s newly developed hydrophobic filter has significantly improved the device’s moisture resistance, making measurements reliable even in changing conditions. The filter prevents droplets formed by condensation from reaching the analyzer’s optical surfaces, increasing the device’s operating time.
Gasmet supporting the customer
According to Hakkarainen, Gasmet has provided help and support quickly and professionally, not only regarding the device’s operating instructions. This has enabled smooth research work and rapid response to changing needs. Without this assistance, problems could have significantly delayed the research.
Research and collaboration – scientific basis for practical solutions
Fertilizer research is just one example of Datasense’s wide range of studies involving the GT5000 Terra. Datasense offers modern IoT measurement stations and data services for demanding conditions in farms and bioeconomy, as well as environmental research. They combine data, research, and practical applications, helping customers make informed and sustainable decisions.
Datasense works closely with local research institutes and universities, such as the Natural Resources Institute Finland (LUKE) and the University of Helsinki. Collaboration also brings practical benefits: students get involved in scientific research and field work.
| Greenhouse gas flux measurements
The measurement of GHGs from soil represents an important part of climate change research. GHGs, such as Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O), released from soils into the atmosphere are primarily biogenic by origin.
