I started my first food plot about 9 months ago. I got my ph near to 7 and fertilized and grew some very nice iron clay peas. A few months later hurricane Faye came through. It drowned my road and I had to replant with brown top millet. It did not grow well. so I retested it last weekend for ph. My ph is now a THREE. I guess Faye destryoed my dirt. So hereare my questions because I do not know how to do the numbers.

How much lime do I need to put down on half an acre to get it back up to 7?

How long will I need to wait for the lime to become intergrated into the soil before planting.

Thank you for your time.
