Llama wool as insulation

Llama wool as insulation

I have access to free llama wool that was quality reject from a manufacturer, so it’s prepped, clean, and high grade.

I’d like to use it as insulation for a studio within a warehouse. The warehouse, as warehouses go, might have rodents scurrying about.

I’ve sealed off cracks, and been pretty fastidious about cleaning and patching holes and spray foam. I’ll also be using natural spray repellant and never keeping food in the studio. I can just imagine the cozy rats nest of plush llama wool in my walls lol.

I’m in Oregon, it’s cold.

  1. Would you advise against it with potential rodent presence?
  2. Would adding DE or other natural powders repel permanently?
  3. Any tips and tricks to using llama wool as interior wall insulation?

Non native is not invasive

I love native plants to my area I grow a good sized garden full of native plants and I understand their place in the ecosystem and how important they are. And I agree people should grow native plants however I have noticed most people seem to not see a difference between invasive and non native while many non native plants are invasive. Many non native plants really aren’t invasive especially very slow growing ones or moderate pace growing ones. A great example of a plant which is non native to North America but not invasive is the ginkgo tree. Ginkgo trees are the only living member of genus, family, order, class, phylum and they are endangered in the wild in Asia. Ginkgo trees very rarely spread here in the USA and have been here for around 200+ years and have not become a major issue. While it may be argued they don’t support a lot wildlife which is true having a few around here and there won’t hurt especially because they are endangered in the wild so by growing them out of habitat we are giving them a chance to survive the mass extinction happening in the world. Another thing to consider is what if the country the plant is native to is very bad about protecting it sometimes in certain situations plants need to be and should be grown in other places. However I hate plants which are common in the wild and actually invasive and do spread such as Bradford pears here in the USA and Morus alba and European buckthorn and stuff like that those plants are common in the wild and very invasive on other continents such as in North America. But it’s important to remember that not all non native plants are invasive species as I said and some especially endangered ones should be grown. And something like a ginkgo trees is definitely not invasive male trees don’t even make seeds the female ones do but only after 20 years from a seed ginkgo trees grow at a moderate pace and have shown them selves not be invasive and don’t really out compete native plants in anyway.

Permaculture Design Training

Permaculture Design Training

Hey!

I’m a landscape designer with a Bachelor’s in Landscape Architecture and a background in architectural design. Though I’m on the periphery of a full understanding of permaculture practices, what I do know really resonates with me.

I want to dive deeper, not just into the practical side, but also the philosophical and spiritual side of it. I’d love to study in a program that emphasizes indigenous practices, art and sacred geometry. I’ve hit a creative/energetic block in my current career path, but the idea of weaving in permaculture is really exciting and energizing.

I’m in the southern Willamette Valley and looking for a program (doesn’t have to be certified necessarily). I would love recommendations for training or communities to get involved with.

Thanks in advance!

Combined application of Bacillus amyloliquefaciens and sodium selenite promotes tea seedling growth and selenium uptake by regulating the rhizosphere bacterial community

Combined application of Bacillus amyloliquefaciens and sodium selenite promotes tea seedling growth and selenium uptake by regulating the rhizosphere bacterial community

Abstract

Bacillus amyloliquefaciens is a widely used plant growth-promoting rhizobacterium. To investigate its role and mechanisms in selenium (Se) biofortification in crops, a pot experiment with four treatments including no application of Se fertilizer and B. amyloliquefaciens (control), B. amyloliquefaciens application (BA), Se fertilizer application (Se), and combined B. amyloliquefaciens and Se fertilizer application (BA + Se) was conducted. The results showed that, BA + Se treatment significantly increased total biomass of tea seedling compared with control, BA and Se treatments. Additionally, compared with Se treatment, BA + Se treatment significantly increased the Se concentrations in root and leaf, and Se content in the whole tea seedling by 101.4%, 34.5%, and 149.5%, respectively; BA + Se treatment also significantly increased the soil exchangeable Se and total available Se concentrations. Compared with control, BA treatment upregulated the expression level of CsPHT1;2b; Se treatment upregulated the expression levels of CsSULTR1;1, CsSULTR1;2, CsPHT1;2a and CsPHT1;2b; BA + Se treatment upregulated the CsSULTR1;1 and CsPHT1;2a expression levels in tea seedling roots. The 16S rRNA indicated that BA and Se treatments had no effects on the diversity of rhizosphere bacterial community, but altered bacterial community composition. Soil pH was the most important environmental factor affecting rhizosphere bacterial community composition. BA + Se treatment significantly increased soil pH and the complexity of rhizosphere bacterial symbiotic network, compared with other three treatments. Furthermore, comparative analysis about rhizosphere soil properties and bacterial community composition and function between Se and BA + Se treatments, suggested that BA + Se treatment promoted soil Se availability by recruiting g_Sinomonas species and regulating the abundance of Se reductase in the rhizosphere.

Bacillus subtilis probiotic enhances ornamental fish survival through ammonia detoxification

Bacillus subtilis probiotic enhances ornamental fish survival through ammonia detoxification

Abstract

Ammonia nitrogen (NH3-N) pollution poses a critical challenge to global aquaculture sustainability. Here, we report the isolation and characterization of Bacillus subtilis DM115, a novel probiotic strain that demonstrates exceptional NH3-N degradation capabilities in ornamental fish aquaculture. Under optimized conditions, DM115 achieved 98.45% NH3-N reduction within 24 h, while exhibiting broad-spectrum antimicrobial activity against major aquaculture pathogens with minimal antibiotic resistance. In vivo studies using koi (Cyprinus rubrofuscus haematopterus) revealed that DM115 not only effectively reduced NH3-N levels to 0.25 mg/L (99.37% efficiency) but also significantly enhanced fish survival (86.67%) through modulation of antioxidant enzyme activities and inflammatory response pathways. Our findings establish DM115 as a promising probiotic agent for sustainable aquaculture water quality management, offering an environmentally conscious alternative to conventional treatment methods.
