Rhizophagy cycle and Air Pruning beds
Hi,
I am making rootstock of asimina triloba and i am interested in some opinions if air pruning the roots affects the rhizophagy cycle?
I need to germinate and grow with air pruning pots/ beds to have a much denser root system then just a pivot with very few lateral roots, as i hope to obtain more vegetative growth in years to come and to be…

As I continue to go through this course, currently in session 5, it is difficult for me to keep up, and being not used to hearing the speaker, difficult just to understand. But my mind keeps searching for not just what is interesting.. but useful.
I’ve heard mention over the last few years (slowly trying to come up to speed) about using Brix as…

I also see nothing, at least in the abstract and slightly more detailed description of that particular study, indicating finding one in 100 kilo. Perhaps there is another study I did not find.

Reply to Redox course : Finding fusarium w/ potato beetle antenna
Reading the more detailed document (the second one listed), and not being an expert, it seems to say not that the beetle senses an electrical difference or that there is an electrical component to the detection of fusarium, but that the olfactory sensing of specific chemical molecules (indicative of fusarium) causes an electrical potential…

Redox course : Finding fusarium w/ potato beetle antenna
In Lesson 5, around the 33min mark, a study was mentioned where researchers used the antenna from a potato beetle, to detect fusarium in one potato in a batch of 100 kilo of potatoes.
I found this study, but the tidbit is that it was “based on” the antenna, not using one somehow connected to a device.“<b…
