hello all, I am here looking for a water soluble K substance for my organic liquid feed for my tomato plant. So far I am using , per gallon, 8 tsp 5-1-1 fish em., 1 tbs 0-5-0 bat poop. But I need some K, so I am hoping one of you big dog organic guru's can help me out here. (Or else its foxfarm time) Thanks for your time.
yea i have been looking into getting a ph meter so i can see if its locked up or if i really do need more K. thanks for the advise. do you use a ph tester? if so what kind? i want to order one but I'm not sure what to get?
How do you know you need more Potash? Is this simply a supposition based on the theoretical nutrients in that liquid feed? What soil is this tomato growing in? Could that soil have sufficient levels of K for the plant? Keep in mind that excess levels of K can interfere with a plants ability to uptake and properly utilize Nitrogen.
I'd be very cautious about putting wood ashes into a worm bin - they are extremely alkaline and also very caustic. Adding much will make the pH inhospitable for the worms and the chemicals could kill 'em. Most vermicomposting sites recommend against it but even those that OK it suggest only a pinch occasionally.
