<em>Urine</em> is a liquid water material formed by kidneys
Fertile soil is valuable because there is a limited supply. Less than one eighth of land on Earth has soil that are well suited for farming.
The thick, fertile soil of the prairies took many thousands of years to develop.
The two ways that the value of soil can be reduced is help use soil correctly, peanuts were once a corp to help soil, and still can be. The soil value recycle rocks and bedrock.
The value of soil is reduced when it loses its fertility and when topsoil is lost due to erosion. Soil can be conserved through contour plowing, conservation plowing and crop rotation. The thick mass of tough roots at the surface of the soil.
Answer:
decay chain refers to a series of radioactive decays of different radioactive decay products as a sequential series of transformations.
Explanation:
Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic.
The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created
“planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
