New monitoring farm to reduce gas emissions
There are significant consequences for reducing global greenhouse gas emissions form the biodegradable sensor research from the Paul M. Rady Department of Mechanical Engineering that could alter how farms monitor, measure, and react in real time to the microbial activity in their soil.
Professors Greg Whiting and Jason Neff from CU Boulder, US, along with Madhur Atreya were the project’s leaders. The research was just published in Advanced Science.
It explains how a low-cost, easily manufactured sensor that uses readily available circuitry can monitor the rate of its own decomposition in real time in order to gauge the health of the soil
Whether it’s our cutting-edge sensor or a rusted-out vehicle, the deterioration of things can reveal information about their surroundings. In this article, we demonstrate how a straightforward biodegradable device’s soil’s microbe activity, which is helpful in a variety of contexts.
Exhausted soil and agricultural supply
Around the world, more than one-third of the soil is exhausted, which increases fertiliser use and, consequently, greenhouse gas pollution.
In order to improve agricultural supply and possibly halt the loss of biodiversity in conservation efforts, it’s essential to obtain particular insight into the quantity of fertiliser used in a region or how healthy that soil is generally.
However, this has historically been challenging to do.
That is partly due to the requirement to remove the soil and sent it to a lab for examination in order to obtain pertinent metrics. It takes time, and during that period, the microbial composition of the sample and the area may shift.
Other methods of gathering this information, either require just an much manual labour or fall short in terms of the team’s goals of real-time monitoring and simple data access.
The Tea Bag Index and Soil Your Undies, ARPA-E programme to check soil nitrogen cycle
The Tea Bag Index and Soil Your Undies are two programs that urge people all over the world to bury things in the soil and track the actual decomposition of those items to learn more about the soil health in the area.
Consider our new sensor to be the electronic equivalent of that strategy. The team is currently concentration on enhancing the longevity an d manufacturability of its instruments.
He said on order to target more precise soil microbial/enzymatic activity, we are looking into other materials that we can use to create comparable instruments.
Additionally, the Department of Energy’s ARPA-E programme recently awarded us new funding that will enable us to investigate various parts of the soil nitrogen cycle.
Prior to enrolling at CU Boulder to pursue his doctorate, Atreya worked as a design engineer in the private sector. He completed his studies in the summer of 2022 and is now a senior scholar at Whiting.
Despite his long-standing interest in ecological design, he never thought he would be working with printed biodegradable electronic. Because soil is so intricate, every sample will differ.
Fortunately, he was supported and mentored along the way by a fantastic team of earth and polymer specialists from engineering and other departments on campus.
