I was feeling pretty chuffed with myself, having just constructed my first compost heap. Then dear hubby points out, not unreasonably IMHO, that it will only produce a little compost, while we have five acres to tend. A soil analysis from a year or so ago reads thus: We have been able to get a barrow load of chook poo out of the chook house and will be cleaning it out weekly from now on, but this is the only on-site source of phosphorus that I know of. The chemist who did the test recommended suflate of potash at 100kg/ha and soft rock phosphate at 400 kg/ha to correct the potassium and phosphorus deficiencies. What is the best use of the compost we are making? How much should we producing for a 5 acre property? What is the best way to correct the slight acidity of the soil and the potassium and phosphorus deficiencies?
