Hi, sorry if this has been asked before, did a search but couldn't really find the answer i was after.

My patch is about 1947 sq ft, i need to add about 100 pounds of lime to bring the pH up.
The question is, can i add the Lime plus the amendments i need ( Copper Sulfate, Manganese Sulfate, Borax, Zinc Sulfate) all at once or do i need to add them separately?
If i have to add the Lime separate and ideally first, how long should i be waiting before adding the amendments?
Any information is appreciated.

I can't remember any info saying these products are not compatible with each other

Anytime I do a soil ph correction I only spread it and till it and wait I want moisture to start the process others I mix and spread in one pass.. unsure if it's right or wrong but I do not mix ph adjusters and ferts

I know farmers mix pellitized lime and starter fertilizers together ( NPK) when they need a quick pH adjustment. Generally they add regular lime separately but I think it is because of the quantity of lime that is generally spread (3-4 tons per acre or more) rather than incompatibility.

So i would probably be best tilling in the lime then waiting maybe 1-2 weeks before tilling in the fertilizer amendments?
Ideally it would be great to not need to add lime and have the pH up to a good point already,
Would be great to hear from anyone that has had to raise their pH and also add fertilizer amendments.

I would think the lime would be a great way to carry the micro-nutrients that you need so little of. You would just have to be sure to mix them in nice and evenly into the lime. Spread the lime making sure you are able to cover the hole patch with that one dosage.

Blue- There's no reason not to add all your amendments at once. In fact, its probably wiser than splitting them apart. Tilling the soil is rough on your soil particles. the fewer times you do it, the better. These nutrients will not cause negative reactions with one another if added all together.

To big moon's point, the lime does make a great "mix carrier" for the micros. when ur spreading a couple of ounces of micronutrient across 1000's of sq feet, adding bulk to the mix for even spreading is necessary, hence the role lime can play.

Since your are in the southern hemisphere you are most likely preparing for next season, correct? If so then add your lime only.


Because Boron leaches, Manganese will lock up in the soil as your ph rises. and copper sulfate will bind with the OM in your soil.

Test again in the spring and see what your Lime has done because the PH change will effect the availability of everything.

If your growing now which seems odd and difficult given your location then add the lime to the whole patch. Then split up the rest into additions you can put down ahead of the plant as you till in the weeds.
