Applying Chevron, the Court considered first whether the statute was ambiguous. Finding it so, it then looked to whether the agencyâs interpretation of the statute was reasonable. Justice Kagan, writing for a unanimous Court, found that the BIAâs interpretation was âbased on a permissible construction of the statuteâ and thus entitled to deference.
Select the proper material for compost. Different plants require special levels of soil acidity to thrive. Use materials such as bone meal for plants that grow better in alkaline or neutral soils and citrus rind and leaves for plants that require a more acidic soil.Verify the pH of the mixture before planting.sing compost instead of topsoil can require a layer from 6 inches for shallow root plants such as violets and oxalis to 12 inches for deeper-rooted plants such as petunias or ferns.
Use of compost in potting soils. Leaf compost can be used as a component of potting mixes. Generally, no more than one-quarter to one-third by volume of the potting mix should be compost, because over time some of the compost is likely to decompose and the volume of the potting soil will be reduced. In addition, high levels of compost in a potting mix may cause waterlogging and poor aeration for roots. Although proper composting destroys most weed seeds and disease organisms, some may still survive due to incomplete mixing.
