I put this post up on here a few years ago. It is the formulas for figuring the necessary lime and fertilizer requirements for your formula. I posted it to our website, You can open the page in a new window, feel free to copy and paste it to a document to save for personal use!

A couple more things i'd like to throw in there. Fertilize to your limiting nutrient. So if you require more potassium (the 3rd number in the fertilizer sequence on a bag ex) 9-23-30) use a fertilizer that accomplishes just that. It is usually more economic to use a 15-15-15 than a 10-10-10 and in many cases a 18-18-18 as 18-18-18 has 1.8 times more N-P-K than 10-10-10. But, also something else most do not know. Your lower number fertilizers contain more "salts". This in my and many people's opinions is a big factor in soil health. Here is an article that talks about that. http://www.soils.wisc.edu/extension/wcmc/2008/ppt/Laboski1.pdf
