Have you tried the catalyst effect to get some of this calcium functioning - calcium nitrate /molasses sugar or sugar and vitamin B12 - or for certified land, calcium lignosulfonate instead of cal nitrate - these products can have a significant effect on weed germination too. > > We've been advised that applying sulfur to the ground What form of sulfur was recommended? Elemental sulfur will generate a strong acid reaction in the soil and can cause rotting of fruit and vegetable crops.
