Reply to Long-term correction of magnesium deficiency in calcium rich soils.
Epsom salt and gypsum are harming organic agriculture and are widespread over-recommended. The sulfate (SO4) requires a ton of energy from the plant to use it. You’re basically oxidizing your soils, which is bad. The only time that epsom salt or gypsum should be used is when you have a very high carbon content, like your soil is black…

For corn and soybean crops most farmers apply nutrients to a field either based on what they see on a soil test or just what the extension service tells them is needed to get a certain yield. So the application of nutrients added is not based on plant necessity. This fertility is added in…

Hi! if you impose hi transpiration on a plant with nitrate fertiliser that triggers a „greed response“, it moves bulk fluid from soil into itself. it is hardly possible that this is 100% what the plant needs at a given moment, so some nutrients that are taken up in excess have to go into storage. most are unproblematic, some cause toxicities…
