Are there here any soil mechanics experts for educational purposes?

Hello, I want to know what the best field test to perform to find the soil type. I usually perform the manipulative and Jar/bottle tests to verify it.

P.S the manipulative test is the one where you make balls and sausages of the moisture soil and see how long it can go before it starts to break!

project

what title says. Is there a specific type of thermometer I should use? does a digital probe work?

edit: also my lab is not a soil lab and we don't have the typical supplies. Does a 500ml cylinder work and how would I change my methods if I use 500ml instead of 1000ml cylinder?

What kind of soil is this? I took this picture 2 hours after shaking the jar

Hi! I'm a shs student in the Philippines. I hope to reach out for those who took soil science as a career. My teacher in Science inspired me to take Soil Science in the future. However, from what I heard many changed careers. May I ask why po? And I'd like to ask if Soil Science is worth it in terms of its salary? Family finance is not so good, there are a lot of struggles, so I'd love to help with that once I'm done with college. That's why I'm asking if Soil Science gives good pay? And how much on average? Please help!

I have a deadline tomorrow and an instructor at a soil institute told us that there is a book by Tubach?? That can help us for our project

THE PROBLEM IS I CANNOT REMEMBER THE AUTHOR OR THE NAME OF THE BOOK

IT’S SOMETHING LIKE ESSENTIALS OF SOIL SCIENCE OR FUNDAMENTAL OF SOIL SCIENCE

PLEASE I REALLY NEED IT

or you can recommend books about soil weathering and soil types

I'm not sure if this is an old idea or just a stupid one but, I was wondering if charcoal could aid meadow creation.

When attempting to make a wildflower meadow from a previously grassy area, the nutrient level of the soil needs to be depleted to allow wildflowers to compete against the more vigorous grasses. This is usually done by hay cuts (removing the cut material) or grazing at specific times to remove the nutrients in the grasses. Over time, along with disturbing the surface to weaken the grass, the application of parasitic flowers like yellow rattle and seeding, the meadows can return to a better state for biodiversity.

So I was wondering if you could maybe apply uncharged biochar - as in, charcoal - to the soil as part of the process. Knowing that the char will leach the nutrients from around it, effectively reducing the fertility more quickly than with other methods alone. Whilst it would, in future, increase the quality of the soil and the potential for nutrient carrying, it wouldn't actually in and of itself increase the nutrient load so wouldn't end up being counterproductive.

Or would it? I really have no idea! Any thoughts?

I live in karachi pakistan I want to study soil testing certification any anybody have any idea please guide me through it

Hope this is okay here. I am a noobish consultant and got an Arrow 200 GNSS receiver for my firm. What field collection device software/app does everyone use for pairing to an external receiver while doing delineations, sample location, habitat mapping, etc.? Thanks!

Might anyone know or have a copy of something that brings together these two? Something that would look like a classical systems thinking map, but the content is soil information? Thank you so much!

I have what is known as "poof dirt" by the locals. I'm on just over an acre and It goes down as far as I can dig. It's powdery soft, not compacted, blows everywhere on windy days, and sticky when wet. Is this pure silt or clay and how should I amend it for a vegetable garden?

Any help appreciated, thank you!

I haven’t grown any vegetables before, I’m planning on growing tomatoes in 10 maybe 15 gallon buckets. I want to make 80 gallons of soil I want to have extra just in case. I have made the following calculations to decide what I need. I wanted to make a simple mix. From what I’ve looked up ice decided to do. 50%, 30% peat/coco mix and 20% drainage pearlite/ vermiculite mix.

How is this mix will this work, I’m planning on doing organic growing .

The 3 varieties I’ve decided to grow are Matt’s Wild Cherry, garden gem, and last is undetermined still maybe a determinate that’s known to do good in containers. I’ve

Hello! I'm a soil science major from SE Asia, is it possible for me to practice my major abroad? Is there any career opportunities there for me as a soil science major from another country? And is there any examination/certification I have to attain? Thank you so much!

I’ve been experimenting with different ways to improve soil health in my garden, and it’s amazing how these methods can make such a difference. Recently, I tried using partially broken-down leaf mold as a mulch layer, and the difference in moisture retention was great. I'm sure it wasn't specifically because of the leaf mold (more so the mulch), but with all else being equal, it was pretty good!

This got me wondering—what’s the most unusual or unexpected thing you’ve done to improve your soil, and how did it turn out? Maybe it’s using biochar, brewing compost tea, or even something wild like burying fish scraps.

Thanks!

Hey people!

So i'm extremely new to gardening and i'm extremely interested in organic farming/gardening principals and i've been learning about it for a while now. The problem is i live in an apartment and own no land but i have a big patio. I've been working slowly on trying to make a potted vegetable and fruit tree garden on my patio , i learned composting and i've been making bokashi compost for about 5 months and i recently started worm bins. Our native soil where i live is sand based and the environment is largely a desert environment so i thought i'd try to replicate that and my soil is made with a mixture of sand and my homemade compost.

I'm planning to continue to reuse the same soil while enriching it with more compost over the years to build the organic matter in the soil. I currently am working with containers and the biggest pots i have are 60 cm in diameter. I also try to plant multiple species in the same pots to try to get some of that plant guildes effects as much as possible to my understanding. I've also been playing around with different homemade and commercial bacterial and fungal innoculums like KNF IMO, LAB, EM.

Recently, i've been reading about dr. Elaine ingham's work in the soil food web and soil microscopy and dr. Christine jones work on liquid carbon pathway and qourum sensing and i was wondering how can i apply these principles in a container gardening setting with reusable soil to build organic matter in the sandy soil quickly and ensure the micro organisms bio diversity and completion of the components of the soil food web, as much as possible.

I'm also wondering if working on applying these principles in a container garden setting is going to help me be better equipped to work with actual desert land to turn it into a permaculture forest and how generalizable are these principles and techniques in the context of scale.

Sorry if i seem to not know much about what i'm talking about 😅😅, i really don't but i'm trying to learn.

Thanks.
