Other aid. Need-based financial aid may be adjusted if you subsequently receive additional aid (scholarships, grants or loans). Private scholarship awards may reduce Board of Governors equity awards, loan eligibility or other aid.
Ways to Reuse Potting Soil. The easiest way to reuse old potting mix? Simply remove old plants from their containers, fluff up the soil and replant. If you've reused the same soil for several years or it's developed a white surface crust, you may have to cut it with 50 percent new potting soil and/or apply fertilizer.
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.
