After I seen the third year core sample of the raised bed, I just had to get a soil test to see what was going on. I have always known that garden worms were beneficial to the garden. But I did not know just how much work they did. Penn State claims a 4-5 day turn around on soil samples. I sent the sample in on Tuesday and received an eMail copy today and a hard copy will be sent via snail mail. I requested the standard test($9) and % organic matter($5) and eMail data($1) for a sum of $15. I was interested in the PH and Fertility of the soil but I was curious as how much organic material was present since the only thing deposited in the beds was organic but the soil did not seem as it was only humus. As it turns out at 25% organic material, I have just been feeding the worms and they have been building up the soil.
