Interesting reading through this thread, I don't use any bought liquid feed, all my plants, get fed with comfrey or seaweed and occasionally adle made with chicken pellets, they get the fed every four days and if as ameno says the adle is chicken ma ure in suspension it still gets absorbed with every following watering which will desolve the solid partials to make it suitable for plants to absorb, I have no scientific facts to prove this, but as I feed my leeks with adle and they grow well enough, I am quite happy to continue to use it
