Soil Color Database

Hello,

I am working on a report the looks into unique colors within the Munsell color book (Specifically the GLEY1 and GLEY2 pages). Is there a way to look for certain colors of soil or sort soil series by color on web soil survey?

EROSION CONTROL BLANKETS???

Do erosion control blankets actually work?

CONTEXT: Erosion (in the forms of flooding, wind, drought, natural disasters, etc.) leads to a lot of blockages especially in roads and rivers.

For anybody that has had to deal with problems due to soil erosion and landslides, have you ever considered or used biodegradable covers/blankets to keep soil in place? What's been your experience with it? If you haven't used these types of products, what would you use instead? Thanks!

I'm attaching some image links so you can get a better idea of what I'm asking.

White powder near basement wall

Hi all, I moved into my new home a month ago and today when I was walking around the home, I noticed this white powder near my basement wall. This was not here a few weeks ago. Do you all know what this could be?

How can I recycle and upgrade my old indoor plant soil?

I have a bunch of soil mix from my indoor plants (which died) and a bunch of dead plant matter (roots, foliage). The soil mix itself is just potting soil, mixed with perlite, vermiculite and coco coir.

https://i.imgur.com/r22vzPol.jpg

I'm thinking of these steps:
-mixing all the old soil and plant matter together
-mix water into it
-get a bunch of rain worms and add them to the mix
-let the worms do their thing until next spring
-profit

Everything will be done indoor. Is this a good way to do it? How would you do it? Are there maybe creatures other than rain worms which are a better choice?

Red Soil Oklahoma

Where is the most red soil in both quantity and color in Oklahoma? I have seen a good bit of it but is there any where specific that has a whole bunch? I would have posted this in the Oklahoma Reddit but I can’t because I don’t have enough Karma.

At what point do you get concerned and dig up dirt because of an oil spill?

My house has well water. The well is about 400 feet down.

I was fixing my skid steer today and about 1/3rd of a gallon of hydraulic oil escaped my bucket and got into the ground.

I dug some of it up, but it’s on hard packed gravel and it’s really hard to dig up. of course, I can dig it up with the skid steer, but then I would have to replace the gravel.

Is this oil spill issued that I need to remedy?

How does weld depth affect your answer?

Thank you

Sodic soil, front yard.

I’m having a difficult getting dense grass to grow in my front yard, backyard is perfect. I wish it was the reverse.

Decades ago, the front yard was deeply (4 ft) excavated by the previous owners for sewer lines replacing, so some really weird subsoil was brought to the surface.

I fertilize regularly, I even killed the entire front lawn with glyphosate and reseeded with Black Beauty Ultra. It looked nice for one year and then got patchy again. I have a sprinkler system.

So a few weeks I saw a soil science video on Sodic soils, and how to test, which involves adding a little gypsum to a teaspoon of soil. After thirty minutes this is what I got.

The untreated soil is on the left. The test indicates I have Sodic soil. I’m just not sure how I can practically fix it.

College project advice

So for our college group project , we want to make a soil tester , for now we want to start with a soil moisture sensor . Out of the following technologies , which one would you guys recommend:- Time Domain Reflectometry Time Domain Transmissometry Capacitance(Frequency)/Frequency Domain Reflectometry (FDR) Capacitance (charge) Differential amplitude (Simplified impedance)

Drying soil in oven?

Hi all

I need to do a soil sample test but it need to be done soon. Presently, I am away from the test area where I collected the soil from. I brought it to my local agway to be sampled and they did a ph test where it was sampled an was given water to be moistened. I need to give it to my local extension office to be sampled again but it needs to be dried. I am away from the sample site and it needs to be tested soon. Can I put it in an oven to dry or would this affect the outcome of the soil test?

Gonna dump Sulfuric Acid

I want to bring down my soil pH more permanently and quicker than traditional short term methods. I have a limestone based soil that I'll calculate percentage limestone and attempt to neutralize it with sulfuric acid per pound. It'll be in mostly empty mulch beds of which I'll plant afterwards.

I wanna dump some Sulfuric Acid in my soil, who's with me?

drying soil?

i’m doing a research project for a class, and as part of this i’m taking soil samples and testing their salinity levels. i’ll be doing this by drying out the soil in the oven before soaking it in deionized water, extracting the liquid, and using a refractometer to measure salt levels.

my question is, how could i effectively dry the soil in a traditional oven? i’ve never done anything like this before so just not sure how to go about it. thanks!
