Now, this is a little OTT for my rather modest Giant Pumpkin ambitions... But I had a tissue test for the big (and better pumpkin) to give me an idea what's going on generally behind the scenes to help focus in future years. An old soil test for the larger site attached too - it's had a lot (!) of cow manure added which will start to pull down pH - but nothing else. Tissue test of "very low calcium" blows my mind. There's 4000 ppm in the soil! Not making it from A to B, although I'm not sure why. Sulphur / Manganese look easy - but boy, I'm trying to get my head around the calcium thing. Is adding plant soluble calcium to a soil which already has calcium (potentially insoluble?) a good idea? Is it there, but other factors (watering, high ph affecting Boron, K competes with Ca) affecting uptake? I also know that calcium doesn't move well. Getting some good input on the Giant Vegetable Facebook group; IanP suggested looking at Boron levels to help Ca flow + lab suggesting direct application to fruit as foliar application unlikely to help increase calcium in pumpkin. If anyone one else has input - please share! Love to understand what's going on.
