Fish bones are made of the phosphate mineral apatite, which readily combines with lead to form pyromorphite, a stable crystalline mineral that can't be absorbed by the human digestive system., Now researchers are using fish bones and other phosphate-rich amendments to remediate lead in urban soils.
Likewise, P-rich soil amendments including manure-derived biochars seem to represent a significant source of P (Chan et al. 2008; Asai et al. 2009; Uzoma et al. 2011).
The addition of P-rich soil amendments reduces the mobility of various trace elements and corresponding accumulation in plant tissue (Cao et al. 2002; Brown et al. 2004, 2005; Kumpiene et al. 2008; Cao et al. 2009).
Compost is a rich soil amendment that is created by recycling food scraps and yard waste.
The aim of the study was to develop an aerobic composting process for chicken blood to produce a nitrogen-rich soil amendment for use in agriculture.
The findings suggest that formulations of biosolids derived from both treatment processes can be harnessed for production of nutrient-rich soil amendment or biofertilizer.
"It could happen first in jurisdictions like the United Kingdom, where there isn't as rich a First Amendment tradition and where libel suits happen much more frequently," he said.
Decisions protecting individual rights may be said to be liberal, too, but many political liberals would reject that characterization where the First Amendment rights of rich campaign contributors or the Second Amendment rights of gun owners are at issue.
Vermicompost is a nutrient rich, microbiologically active organic amendment which results from the interactions between earthworms and microorganisms in the breakdown of organic matter (Lazcano and Dominguez 2010).
Two different amendments, an iron-rich water treatment residue (Fe-WTR), a municipal solid waste compost (MSW-C) and their combination (Fe-WTR + MSW-C) were added at different rates (from 2 to 4% w/w) to three mining soils (S1, S2, S3) mainly polluted with As (from 371 to 22,661 mg·kg− 1 d.w).
Where did we get the idea that the First Amendment means that the rich must be allowed a louder voice than those with slimmer wallets?
