Hi, I was really curious, I'm getting a snake plant, and I heard you can cut off leaves and re-grow them, what soil do they need? Is it peat moss? I searched and they need some succulent soil but it's not available anywhere in my country, so can I just use peat moss soil?

Soil scientists/professionals, where did you get your degree and what program was it?

I'm thinking about going back to school to get a master's degree. I'd like the program to have something to do with soil science, whether it's ecologically or agriculturally related doesn't matter too much to me. Does anyone have any recommendations for schools in the US with good soil science programs?

Wife accidentally spilled possibly half a quart of new and unused synthetic blend motor oil in the yard by our house. How serious is that?

Soaking up some of it with baking soda but some did end up in yard. We don’t have well water but still a little anxious.

Why doesn't loamy soil turn into concrete similar to what everyone says about adding sand to clay soil?

Isn't loamy soil essentially clay with sand and shouldn't it be similar to just adding sand to clay soil (assuming well mixed)?

Where can I buy subsoil?

Hello. I need subsoil for a design project where I am trying to recreate a small rammed earth wall. I find a quarry close to me that sells fill dirt which is close to what I need but they only sell it starting at 3 yards which is far more than I need. I only need about 10 gallons. I have been looking all over the internet for craft quantity but it seems like its not available for sale at that quantity. Might people here be able to point me toward any source that could be relevant and helpful to what I need? Any help is greatly appreciated!

Soil structure questions

In 2023 I had a soil test done about a month before I took a skid steer to my yard and corrected minor grade issue/fixed ruts and holes. This year I used another soil test and the results shocked me based on the amount of feeding I gave the new Bermuda lawn.

I assume this would be because of the soil structure being compromised during grading.

Is this normal? How should I handle this?

And a dumb question but can nutrients "re-settle" in place? Or are those old nutrients lost?

Where to find soil science jobs?

I’m going to finish my masters in soil science this year. Since I’m getting close to graduating, I’ve been starting to look for jobs. My undergrad was in plant science and my research has also had to do with plant nutrition. I still really liked learning about soil and learning how plants and soil interact with each other. I would like to still find a job that works with both plants and soil but as I’ve been looking I’ve ran into some questions.

I haven’t done much looking yet, but I got the impression that looking at the USDA and other federal agencies would be the best place to find a job in my field. The thing is, I haven’t found very many jobs on USAjobs and from what I’ve heard, it can be hard to compete for those jobs if I’m not a veteran.

My questions are Is it hard to get a job in the USDA or other federal agencies? Where are other good places to look for plant science or soil science jobs? And finally, how possible is it to find these kinds of jobs in Washington or Oregon?

are mval Ba/100 g comparable to mEq/100 g when measuring soil CEC?

I am familiar with the later but not with the latter. Is the conversion 1 to 1?

Odd blue powder

Weird blue power about 6 feet down. Cariboo bc. Volcano that was once active in area if that makes a difference. Curious to see if anyone knows what this is

Why doesn't "soil" in Florida (and maybe other tropical places?) ever improve?

Sorry for the super basic question(s), but I think about it every time I'm digging around in the sand that is my yard.

I understand that the ground is sandy and nutrients just wash right through - ok. But Florida has existed for 20-30 million years. It's been generating lots of biomatter on top of the sand for most of that time, right? I've also been told that there are layers of clay (at least in some areas) just a few feet below the surface.

So how come the ground just... never improves?

Does soil formation just take longer than I'm imagining? Is it the constant rain? The karst underneath that lets everything just wash through? Would Florida eventually develop real soil is everything continued as it has been? Something else entirely?

What about other tropical places? Does this mean that if we kill off the Amazon rainforest, it'll just do what my backyard does, and turn to sand?

Thanks to anyone willing to explain these basics to me.

Edit: Answer seems to be longer growing seasons keeping the microbes active year-round.

So I guess another add-on question for me then is, are people expecting widespread soil degradation in currently-rich soils? Like the chernozem in Ukraine? And on what timescale would we expect to see that?

Volcanic sand in soil

Hi everyone. I'm looking to improve my soil's filtration and overall composition. It's mostly silt with a little bit of clay and l'd like to add some sand to it. I don't know how much volcanic sand will affect the pH or if it will compact the soil rather than aerate it. Is volcanic sand a good option? Or should I go for the much more expensive silica sand?

Raw soil testing - any risks?

I had soil from my small city backyard tested, and some of the nutrients came back “high”. The plants currently growing seem to be thriving, so wondering if there is any risk or watch outs for these levels? Anything to be aware of for humans or pets?
