I have 4 raised bed measuring 2' x 8' and 1' deep. They are all treated the same, fish emulsion last year when fertilized and compost mixed into the soil at the start of the growing season. My composting style is lazy only turning when needing exercise or feeling quilty for neglecting the pile. I add kitchen scrapes, no meat, lots of cut grass clippings, shredded paper and one year my husband raked up the neighbors leaves since we don't have trees. When I add compost to the garden I just dig down to the bottom of the pile until I reach something that resembles dirt and use that. I had a soil sample done and the results came back for one bed:P 6716,K 3410,Ca 1970, Mg 2095. the soil ph is 6.9. This sample was taken in the fall after the sweet potatoes came out. THe other beds were within a normal range. My question is: does using grass clippings as the main ingredient in my compost pile alter the nutrients of the compost and should I not be adding so much grass clippings? I also mulch with grass clipping that have started turning brown. The produce yield is pretty average from year to year. I am also thinking that maybe the results were flawed but would still like to know if using grass clippings is bad since we mow 2 acres and a mulching blade is very expensive. thanks for any and all input.
