Pear orchard Ph adjustment
I received some advice from folks on here that pears can suffer from chlorosis on alkaline soils. The pears do not show any symptoms of suffering but it can be not visible some say. My ph is 7.7 and I have a few pears planted in this soil containing Very High levels of Calcium. How much Sulfur or Iron Sulphate do I need per pear tree to knock the ph levels down 1 point to lets say 6.7?
How long does the Sulfur effect last for, does the ph eventually creep back up to its natural level after a while?
