how accurate is the testing, it's only a minute sample, of a big area.I didn’t apply any bagged K on a field last year. Was index 3.9. It did get about 40kg/Ha from poultry litter before 1st cut but that was it. 1st cut 6.5TDM/Ha, 2nd 5T, 3rd 4T. Tested after and only dropped to index 3.5, thought it would have dropped further.
