Had some fields tested in August 2019 and applied lime @ 2t acre. just had the same fields retested and one that was ph5 has now lifted to 5.5 Which is just what I was expecting it to be. Now the field right next to it similar soil type but a hay field was 5.4 and has retested at 6.4. Is it possible that it could of increased that much in 20 months? Or was the original test wrong or the recent on? There is also a big variation in the P index in the first field and the K index in the second I am aware that time of year and how dry or wet the soil is can alter results but both were done the same time and conditions.
