Applying Lime, Potash and manure at the same time?

Question

Will there be any adverse affects if I add Limestone, Sulfate of Potash and sheep manure at the same time to the sandy soil in my vegie garden before rotary hoeing?

Answer 1

Lime neutralizes nitrogen.  So adding lime and manure at the same time is a big ol' waste of money since they cancel each other out.

That's why farmers add a thick layer of lime to the soil before they heap on the manure to let it compost.  It keeps the nitrogen from seeping away and into our water.

Answer 2

No actual harm, but it may not be the best strategy.

I assume you have checked the soil pH and you know that you need lime? Also, why add potash. Do you know that your soil is low in potassium.

I would till in the manure first - it needs to be well composted. Then check the pH and nutrient levels, via your local Agricultural Extension Service or with a kit from the garden store. Then add the appropriate amounts of chemicals if you need to.

Personally, I would also add a ton of compost before I added any of the other ingredients. It will do more for your sandy soil than anything.
