Depends on several things :
1. Is this pure horse manure (no straw) ?
2. How old is it ?
Adding pure, fresh horse manure will make your soil more acid.
Adding well-rotted pure horse manure - less acid, but depending on whether the muck was covered up/outdoors, some of the nutrients, especially Nitrogen, may have leached out / evaporated.
Fresh manure with straw : straw [high Carbon] will have the effect of 'locking up' some of the Nitrogen until the straw breaks down, when you get a more stable [hohoho] form of N, which is a good thing - slower release for plants.
Well-rotted manure with straw - straw should have broken down at least partially [see immediately above]
Adding manure will always make your soil more acid.
So, how I work it on a 4-course veg rotation is :
Manure in spring onto Spuds (they like acid - pH 5.5 - soil and need manure)
Legumes in last year's spud bed - no need for manure, but lime in autumn to increase pH to 6 or 6.5 before spring bean sowing
Brassicas - lime lightly in autumn to return pH to 6 or 6.5, optional spring light application of muck
Roots - leave soil well alone; no lime, no muck. |
