5:01 "For granted ground ?" Here in Brazil we are using Calcium / Magnesium Oxides in small doses which provides sufficient Ca and Mg and elevates pH a little. Oxides are way faster and concentrated than lime ;)
thank you for sharing. Can you tell me how long does the sulfur last in the soil? How long does it maintain at that level? How often do I have to add sulfur to the soil?
Brain said no more than 2400 lbs at one time. How long does it take for that to break down? How long does it take to change the pH? Most of my ground is in the low 5's and is sandy loam soil. Thanks for the videos. There very helpful.
It's rainning(monsoon) and my soil ph is at present ph 4.5. What should I do to increase my ph to ph 6 or 6.5 post plantation? Should I use baking soda or calcium nitrate or etc..?
I'm just an ordinary rice farmer, I have a low pH problem, my rice plants look stunted and the leaves turn yellow, is giving lime an instant solution? The problem is I have planted the rice. I can't drain the water because of the heavy rainfall? what if I give him Ca(calcium) fertilizer by spraying it on the plants?
I have been watching all of your soil analysis videos and this video on how to fix low PH just triggered something that I would like to clarify. Situation: In Central Illinois, it seems that everyone puts lime down about every 5 years, which I assumed was normal based on the soil samples showing PH decline over the years. As background, we have been growing 250-275 bushel corn and only applying a fall anhydrous application. Questions: 1 - once we correct our lime to a 6.3 to 6.8, should we expect it to remain in this range over the years if we are properly maintaining the nutrients OR is it normal that the PH will decline over the years even with proper nutrient maintenance? 2 - Our CEC is around 10-14 and we usually apply 200 lbs of anhydrous in the fall for the upcoming corn season. If I understand CEC correctly, we should be limiting our nitrogen to a max of 140lbs. (10x the CEC) 2a - Is my understanding of the CEC vs anhydrous lbs correct? 2b - If we have been putting down this rate of anhydrous (too much nitrogen) I understand that it can leach, but also could this be a contributor to the reduced PH over the 5 year period?
