I have been increasingly interested in 300 bushel corn and what dynamics of that soil will give up that yield. 400 bushel even. These agphd guys are a valuable source IMO.
yes, they focus on yield thats for sureI have been increasingly interested in 300 bushel corn and what dynamics of that soil will give up that yield. 400 bushel even. These agphd guys are a valuable source IMO.
to be fair his fields look great, i suspect a lot of money and a lot of work went in to thatThere take on K (From the corn side). They talk about Francis Childs who was the first in the US to grow 400 bushel.
Plant nutrition depends on the activity of membrane transporters that translocate minerals from the soil into the plant and mediate their intra- and intercellular distribution. The genome of Arabidopsis thaliana appears to encode >800 membrane transport proteins, 65% of which are secondary active transporters. Classification of these co-transporters has been based on both phylogeny and their known or predicted functions as transporters for cations, anions, and organic compounds, including sugars and amino acids (Saier, 2000). In plants, most co-transporters are energized by the proton electrochemical gradient generated by primary proton pumps working in all cell membranes, but alternative couplings also exist. Multigene families, whose members often exhibit overlapping expression patterns and a high degree of sequence homology, encode most types of plant membrane transporters. Furthermore, more than one transporter family transports many inorganic nutrients. Their extensive array of membrane transporters may provide plants with flexible strategies to cope with fluctuations in their environment and to minimize the adverse effects of nutrient deficiency and an excess of toxic ions.There take on K (From the corn side).

At the moment, nothing. We've moved to the Mojave desert and the pest (and WIND! OMG the wind out here can be insane) pressures are extreme. They even munch down cactus if it's green. But, when I get my greenhouse it's going to be aquaponics, so water samples only. I was hoping to add this idea to the whole mix concerning forms of Ca, especially when considering the adverse effects of excess CO3 and/or S.Calphos won't move your pH, nor will it work well if it is not applied to an acid soil or well worked into worm castings, etc.... even then, it will be super slow and cannot be depended on for an annual crop such as yours.
Gypsum is for an alkaline or neutral pH soil/media. It is a calcium and sulfur source. there is no phosphorus in gypsum.
What is your pH and what are you growing in? Regardless, if you really want to dial it in, send in a soil sample....
wow good luck you, this sounds like a brave move, I am sure you will have it zipping along in time regardless of the challenges. Keeps your mind in good shape I reckon to embark on such adventure :-)@Ecompost -- VERY helpful and exactly what I was after, thank you! I hadn't even considered the fact that S is antifungal. Whoa. Great point.

I use a product called CaFeMg to manage Ca and Fe in my AP system and it has worked *very* well. It's from Sensational Solutions and I can't recall whether or not it's derived from SRT. I imagine that I'll need to take greater steps to manage these minerals in our new location as the water is amazingly clean when compared to the well water I was working with.
yes this is the same in humans I understand, hence why a vit D and K sup seems to make sense.@Ecompost
Extra Calcium helps uptake extra K
loves me some Ray, he is a proper dudeQuick question comes to my head while watching this video; In ag, when the word 'lime' is used, my own understanding was that the same thing may not always be what's being referenced, EG, ag lime versus quick lime (?). I'd like better clarity for everyone reading this thread, what type of lime do you think of here? In the meantime, I found this paper.

Whoa, comparison of root tips @4:40!! Sufficient Ca can bind with available P before Al does, too. Damn!!
The discussion of herbicides makes me want to cry. As does the discussion regarding tilth and how to properly achieve it. Are any of you familiar with Ray Archuleta (I love that surname, chuletas are pork chops in Spanish)(Chuleta!)?
We know there are better ways to achieve soil tilth than the implement methods being mentioned in the previous video. Mr Archuleta discusses methods I think we'd agree are more in line with what we prefer. He doesn't seem to have his own channel that I can subscribe to on YT, gotta look harder.

I agree we need to blend, we should always be taking the best current practice across the lot in all aspects of life. I added these examples to help explain a little about pH but I think @Seamaiden 's post from Ray is where what Elaine says is taken to another level and is more closely linked to Ag.The more I read the less I agree with some of the things she teaches. Not necessarily in your examples though. I think she is mistaken in thinking biology is the answer to soil so often. I think you can see the damage in all the organic forums. We have to blend all we learn. But what do I know? I'm certainly not selling anything though.
