We have had the results from the agronomist. PH was 5.8 and for grass needs to be about 6.5 - 7 (out of 14), Potash and Phosphate were ok. He recommended that we cut the paddock really low, box and dispose of the cuttings. Then using granulated lime put on 200kg and 1.5 cwt of fertilizer (20/10/10) per acre, leave for 7 - 10 days then spray with Headland Transfer , a selective weed killer. This is the stag we are at now and although we only sprayed on friday the buttercups, docks and nettles are black and withering already. Then in 10 days time we are to chain harrow to loosen the top of the soil and spread new grass seed, a horse and pony mix, roll in and leave for a further 3-4 weeks. Hopefully this will get the job done. Will keep you posted with the results in 5 weeks time.
