Definition as written by Terry:
Leaching can be negative or positive, depending on the situation.
Plants that have been fertilized with water-soluble fertilizer (such as Miracle-Gro) for too long will build up salt residue in the soil, and leaching can help reduce the toxic effects of this buildup.
On the other hand, compost that isn't used promptly can find most of its beneficial nutrients leached away by rainwater
