Managing Crop Nutrition During Reproductive Periods
Вставка
- Опубліковано 26 чер 2019
- At AEA, we recognize that many crops have the genetic potential to produce far greater yields than are routinely harvested. A critical limiting factor that often contributes to decreased yields is insufficient support of the plant’s reproductive functioning. In this webinar, John describes how blossoming, pollination and fruit development in plants can be likened to the human reproductive processes and which minerals provide the hormonal and nutritional support needed to build a crop.

I always learn something new and helpful from these podcasts (getting this on UA-cam). For example, to quote from one slide during this presentation, “ Lack of nutritional integrity at the transition FROM vegetative TO reproductive triggers proteolysis and creates disease/insect susceptibility.” This example of reallocation of nutrients can also be tied to honeybee health. If a nurse honeybee has a lack of protein in her diet, her own body will provide the protein to feed the larvae. This is non-sustainable and makes her susceptible to disease. Wouldn’t be surprised to find a similar application in human health.
Thank you... from mexico.. very useful webinars ... you are my guru...

Great
What stade would bud initiation correspond to for wheat and canola ?
I've seen a wild appletree absolutely covered in dark furry caterpillars I mean not a leaf or branch visible.they ate it bare but the year later I've never ever seen so many fully ripe apples on one tree ever in my whole life.
Good information
Is phosphorous and Calcium EDTA is compitabel
`Thanks
When you don't have irrigation, can water be limiting to the point that maximizing yield with foliar applications becomes useless ?
How do we ensure that our plant is utilizing calcium as its main component for vegetative growth? I understand how to apply the calcium, is there another step. Obviously I would not apply additional nitrogen.
Hi John. Thanks for an eye opener material. When will be the next webinar and how can i be one of the listeners to ask you a question? Thanks.
👍
I am designing a climate battery greenhouse. I want soil temperature above 70 degrees 12 months a year. I would feed nutrients to earthworms to produce amino acid chelated N, Ca, Mn, P, K, Mg, B, Zn and the rest of the nutrients plants will need. The plan is to have soil biology and nutrients needed for every crop before the first seeds are planted. Would the availability of all that N, Ca, Mg, Mn, P, K and every other mineral mean the plant would have too much available at critical points? Would I get maximum fruit fill for tomatoes? Or would I be better off with foliar sprays and not so much amino acid chelated minerals in the soil 12 months a year. I might have to have a separate Red Wiggler worm bin to produce certain key nutrients in sufficient quantity.
I know for strictly seed production, in cannabis throughout flowering stage higher levels of nitrogen are established and utilized. Many big time breeders and seed producers use this for heartier seed crop.
What are your thoughts on Aragonite as the Soil calcium source? I spoke to a food forest enthusiast who swears by it to “sweeten up the soil”. It’s a more immediate source of calcium for the growing season if lime was not applied the fall before.. What about a slurry of crustacean insects? I know black soldier fly larvae are very high in calcium as a chicken food source.. How bioavailable would it be for the plant if you made a slurry of them and applied to the soil? Or you could put out sticky traps and catch all those hard shell pests and return them to soil as a slurry..
I always hear that analogy, to switch from sweeter to more sour food sources during transition/pregnancy phase

Wow look at the blossom on those trees. That's shouting out with colour look at me look at me I'm important I grow fruits. Those trees are just showing of .Who says humans are the only ones capable of being vain.
Thanks as always AEA! On the question at
