Colonel, I love Matt from the grass Factor, in fact I've been watching his live feeds on Saturday last week Sunday, matter fact somebody was on their live with the name "colonel" was that you?? He's definitely a excellent source of great information. and I actually asked him that exact question about lime. He said because I had so much calcium and magnesium that I should definitely stick with Calcitic lime. I watched all his YouTube videos some two or three times he has so much information. It's hard to take in, all the info at same time.
Yep, that was me on the live stream that he had prior to his Q&A session this past Saturday with Pete!
I talked to my extension agent today, and he explained a few things to me that I'll pass along to you. I explained that you had the Soil Savvy test, and where you lived. I also told him, according to your posts, that you're planning on using humus to incorporate some OM into your soil. He asked if it was humus, or compost; to that extent he said he would recommend compost over humus, because it can take "an extremely long time, on the order of decades, for humus to break down, and see any noticeable benefits from incorporation into his soil." He suggested that you look to using compost.
He also said that regarding your high Na content, the area by the bay is always going to exhibit high concentrations of Na, due to your locale to the ocean, and the measurements that are on the test aren't out of the norm. We discussed how to raise your pH, and he agreed that it would be best to use both types to bring up your pH, and since you're dealing with such a small lot, it won't take much material to affect some change. Regarding your Mg and Ca ratio, it would be something to be concerned about if your ratio dropped below 2:1, so you wouldn't see any detrimental effects by adding either source of lime to your soil.
We talked at length about a humic and fulvic acid, and he mentioned that there is a century plot, not too far north of where you live. They're on about year 30 of a century long test of this area where they're trying to study the reintroduction of carbon back into the soil, and to date, they've only measured about a 2% increase in the return with the utilization of humic and fulvic acid. It's pretty interesting stuff.
He did say that the Master Gardeners there are pretty active, and a quick search turned up that you can go talk to one at several locations through the month. This Saturday, they're going to be at the Pittsburgh Farmers Market
, which would be close to your city. I'd suggest you ride over there, and beat the bushes and get face to face with someone. Keep in mind, it's your tax dollars that pay their salaries!
