Quick explanation of the Micro:bit Educational Foundation moisture sensor I prototyped this week. The microbit measures the current diff in the soil to show relative moisture. #microbit #microbitprojects #makereducation #stemeducation

@microbit_edu Nice!

@microbit_edu Or you could download a flood dog. We made them free. They measure ground water in real time in a mesh.

@microbit_edu Sean, it is possible to do this as a soil sensor for heavy metals? Imagine 2 containers of soil: 1 is control & other has gold flakes (as a mock heavy metal soil toxin) & you desiccate both soils & then add same amount H2O, would soil w/ gold flakes show higher conductivity?

@LEARN_Ped @microbit_edu Thank you very much, the code is from a project on the @microbit_edu website. It's such a great project for students to see connections between the biology of plants, electronics and microprocessors.

🖍️Looking for a fun simple project for kids who are new to the #microbit? They can turn a few pieces of LEGO and a geekservo into a simple drawing machine that's easy to code with MakeCode for the micro:bit.

Solar panels far better for soil moisture retention, better crops better soil quality. Despite the likes of Barnaby Joyce and others claiming #solar farms destroy farm lands even in the face of overwhelming evidence and data to the contrary. #auspol

Research on CA fires shows a majority of the extra burned area in recent years is explained by a moisture gap (vapor pressure deficit). Warmer air expands the capacity to hold moisture and demands that extra moisture from vegetation. Over the long term that drys the ground out.

A sizable surge of tropical moisture will set the stage for possible flooding downpours this weekend and next week across the South and East. There's long-distance moisture flowing from the Pacific, where El Niño-related warmth is building, as well as the Gulf and Caribbean.

We began harvest yesterday, starting early to avoid the mid day heat. Most of the field was well ripe at 13.8% moisture, but the headlands dragged the moisture content up. Yields were ok, but I think the drought will hit the later crops more. #harvest25 #barley

I’m growing potatoes in a laundry basket! I layered soil, seed potatoes, and straw all the way to the top, creating a breathable, well-draining space for them to thrive. The basket lets air flow and prevents rot, and the straw helps retain moisture while keeping the tuber

#WATCH | Delhi: On Delhi cloud seeding, Manindra Agrawal, Director, IIT Kanpur, says, "We tried it yesterday but unfortunately could not get rains because the moisture content in clouds was quite low at 15%. We then thought that we'd do it today with the expectation that we'd get better moisture content today, but this morning we learned that today's moisture content is even lower. Therefore, we decided to postpone it and wait until we get a cloud with reasonable moisture content. Whenever we get that, we'll do the seeding. At least 40-50% moisture content is required. I don't think the prediction is for tomorrow, but maybe in 3-4 days..."

Amazing things happen when soil is revitalized! Healthy soil forms the bedrock of a greener, cooler planet. As the second-largest carbon sink, it is pivotal in reversing climate change. Further, increased plant cover helps regulate the Earth's temperature by providing shade and releasing moisture through transpiration. #SaveSoil

Deadly summer heat dome intercepted. THE DREADED HEAT DOME HAS ARRIVED! Temperatures are surging this week across the Great Plains, Mid-South, Southeast and Great Lakes Regions this week with deadly triple digit heat indices. The heat will maximize across the Mississippi River Valley in combination with extreme moisture. I will have to pound through the heart of the heat dome in the Dominator Fore to chase the severe weather up there #stormchasing #Dominator

TEXAS FLOODS-Here’s a radar loop from the main event. From Thursday afternoon, July 3rd, through Sunday evening, July 6th. A leftover “plume” of tropical moisture from the remnants of Tropical Storm Barry surged north into the state, in combination with elevated moisture from the eastern Pacific from Hurricane Flossie. A shortwave trough emerged from the northwest along with some upper spin from the Gulf, and aided the formation of an MCV over central Texas. Starting late Wednesday, a funnel of this tropical moisture began feeding into the Hill Country, and along with the approaching shortwave, fueled the development of the MCV or (mesoscale convective vortex). This “spin” or the MCV, continued to produce widespread tropical downpours and thunderstorms overnight into Friday morning, July 4th. A burst of low-level air and moisture transport, what’s called the LLJ (Low-level jet) also continued to funnel moisture in to this MCV and continued storms overnight. This was where the bulk of the flooding occurred, and filled downstream rivers and tributaries. Each subsequent day brought bursts of convectively-driven showers and storms that would further exacerbate the flooding situation, on top of what already fell. This continues today, with more showers and storms forming as we speak. #txwx #TexasFloods

The foundation of soil health comes from the soil microbiome. This incredible reservoir of countless microbial species is the key to making the substances that make up the soil into a live environment, teeming with life. Just like they are the foundation of a healthy soil, they are also foundational to our lives, as our health and wellbeing depends in part on our connection to the soil and its microbiome. #SaveSoil #SoilHealth

The NFL has swapped out the field at Allegiant Stadium, shipping in a new field from California for the Super Bowl. They've been testing the soil temperature and moisture for weeks while also using a robotic device to simulate cleat movement. Pretty cool.
