best time to spread muriate of potash

were low in it here too but okay on lime, recommended on the report to spread 19-0-15 after June. I had also heard before that there is better uptake of it in the second half of the year. Were not going with 19-0-15 x4 times, instead going once with Potash.

we need to spread a good bit of this according to our soil tests and lime also,
When is the best time to spread it, i assumed around now would be ok the same as other fert but someone said it should probably be spread in the autumn ? would that not be a waste?
how long before stock can graze afterwards?
i wont be putting out lime until the autumn so it would suit better to do it now really

This depends on soil fertility and soil type. On peaty soils it is best to apply P and K during the growing season because peat has a poor capacity to retain fertiliser. Potash shouldn't be applied to sandy soils during late Autumn/Winter as it is readily leeched from sandy soils. On non-sandy mineral soils where soil fertility is poor (Index 1) it is best to apply a fairly large application of P and K in the Autumn in order to promote tillering and root development. As soil fertility improves (index 2 or better) the timing of P and K becomes less critical but there are time and labour advantages to applying P and K with nitrogen during the growing season. Risk of losses should be less with smaller more frequent applications of P and K during the growing season compared to a large single application out of season.
