Plants love biosolids - hops, wheat, switchgrass, fir trees...the list is long and the supply of biosolids is endless. Using biosolids as a fertilizer and soil builder replicates our earth's natural process of recycling nutrients and organic matter.
Nature’s recipe for healthy plants
Biosolids contain not just one or two nutrients, but all 16 nutrients that a plant needs to grow big and healthy. For nearly 40 years, biosolids have returned the nutrients that we consume to grow crops, reclaim mine lands, improve timber growth and revitalize landscapes.
Biosolids are worth their weight in gold
Biosolids have monetary value to farmers as well - an estimated $49 per dry ton in fertilizer replacement value of nitrogen, phosphorus, potassium and sulfur (based on field trials conducted by WSU, OSU and University of Idaho).
Gardens in the city
Urban gardens have used biosolids to turn concrete jungles into a flourishing green oasis. Biosolids help bind metals and turn soils stripped of organic matter into a foundation where plants can grow. Biosolids in urban gardens gives you both safe soil and healthy plants.
Want to make your rhododendrons the envy of all your neighbors?
Research by Oregon State University shows that biosolids composted with woody material is the very best way to make your rhodies thrive.
Researchers tested 9 composts on rhododendrons, azaleas, and blueberries and found that compost made with biosolids was the only one that met and exceeded the professional growing standard.
When asked why they chose GroCo compost made with Loop®, it was clear that closing the Loop was just one of the reasons faithful customers look to GroCo - here is what they had to say:
- I learned about it at the garden show - NO WEED SEEDS!
- It is rich and nutritious for the plants and because it is composed of recycled materials!
-It's natural and safe for pets (Francisco shown here)
Biosolids serve as a filter for soil
Rain gardens and engineered ditches with special plants, called bioswales, use natural processes to help store, drain, and clean stormwater. Plants and soils are great natural treatment centers for stormwater that not only grow beautiful plants, but also help protect our local water bodies and keep our salmon safe. Special soil mixes are used for these stormwater projects, and the University of Washington wanted to see if composts made with biosolids could be used. Biosolids have a lot of nutrients that are great for growing plants (but not so great for our local water bodies). The researchers wanted to see how biosolids performed, and what performance standards could be used. So far, compost made from biosolids has similar performance to other commonly used composts. This study is still in progress, so stay tuned for updates!
