Little River, TX | Yes I used the Jar Test and for me it worked. showed 0 reason to use gypsum.
Prior to this I had two Ph.D.'s insist I could benefit from gypsum. I was pig headed and obstinate and insisted it would not do me any good. One of these professors became rather heated when I went against his recommendations. It turned out he is from an entirely different soil type, and the only Texas Blackland he had seen was through a windshield.
Their theory was the gypsum would make magnesium water soluble and it would leach out of the growth zone. The magic was to also reduced the soil crusting, and tendency to crack. It is very possible he/they have never seen virtic or vertisol clay soils and did not realize the cracking is a characteristic of this clay type. | |
