This is something new that I haven't seen before. Core samples taken at different depths could be a game changer. Glad you showed us. What is the name of this product and exactly how does it work?That's exactly how it's done, with a core sample. It just doesn't get any better.
The scale was actually developed for gun powder weights many years ago but i use it because it weighs in grains and the sample can be dried in minutes in a microwave if a person is impatient. I also find it useful to determine MC of wood. For drying wood samples it's recommended to keep the °F or °C below water boiling point so i follow thet suggestion for dirt. When the sample ceases to loose weight it is said the MC is 0.0 % moisture. Some scientists will probably NIT-PICK and disagree but what the hell, we're drying dirt.Can't quite see how its going to work, the picture shows a form of balance, scale pan on the left, pivot on the left of the cast? piece then on the right of that what could be a spring or indicator (it's a really small, blurry picture so detail is hard to make out)
So I presume use would be to take sample using soil corer, place on pan and read then dry in oven at x° for n hours and take a second reading, difference is weight of moisture in soil sample.
I'm not understanding a need to take the sample within the root zone of a plant to check soil moisture, but regardless of where someone wants to take their sample I've pictured the 3/8" sharpened stainless tubing I've made to accomplish several tasks here at the ranch.So, how do you take a core sample in the root zone of a tomato plant 6 inches deep?
I can see how this can work. I'll see if I can scrounge up a piece of pipe and something to push the dirt out with. I have a bunch of different vegs growing in containers, some root bound, some not, I think. This can give me a better understanding of what is going on out of sight in the soil plus tell me how much moisture is there.I'm not understanding a need to take the sample within the root zone of a plant to check soil moisture, but regardless of where someone wants to take their sample I've pictured the 3/8" sharpened stainless tubing I've made to accomplish several tasks here at the ranch.
That on the scale, original weight was 60 grains, dried weight 48 grains.I must admit I hadn't thought of special scales for weighing gunpowder. For UK and other metric users 1 grain = 0.065 grams.
How big a soil sample do you take?
