[QUOTE="Jogeephus, post: 1491378, member: 4362"] There are so many things that could make this happen it will make your head hurt trying to figure it out. Just so many combinations from sampling differences to the method used in the lab and like Dave said it could have to do with the time of year because the amount of root respiration and the breakdown of organic materials can affect it especially if your soil has a low buffer capacity. Since your pH increased and if I remember right you had some drought conditions last year my guess is you got the pH bump from the weathering of cabonate parent material. This typically happens during hot dry conditions and is more evident on soils having a low buffer capacity such as sandy soils but the longer you keep it in pasture and the more organic material you add to the soil the less fluctuation you will have in the pH.
