Reduce toxic runoff. Use earth-friendly fertilizers.

While natural fertilizer may bring manure to mind, compost and worm castings are practical options and don’t pose the ammonia problem that manure can. Both are far more earth-friendly than conventional fertilizers, which contribute nitrogen runoff to waterways, feeding algal blooms and killing off large swaths of aquatic life. Compost is all that most soil needs to keep it healthy and productive, but for quicker results, spray a mix of worm castings and water on your plants. Compost and worm castings cost less than conventional fertilizer since they help to build up the healthfulness of the soil.
