Compost is widely used in both industrial and home gardening. Unless it decomposes properly and completely, it can be a source of weeds and other undesirable plants, and, if toxic, can do more harm than good. We can test your compost to determine if it contains undesirable components and if it produces symptoms of toxicity in seedlings.
Soil and soil-less mixes can also be tested. In addition to seed searches, we can test the soil for germination potential.
Tests we have done include:
To be tested, the compost must be completely decomposed and of yard or vegetable origin only, no animal products or animal waste material. It must not have poison oak in it, and if it contains plant material that was exposed to potentially harmful chemicals (i.e. herbicides and pesticides), the chemicals must be identified so the analysts can take proper precautions.
