Great information. It is mind blowing to think plants can sense when severe weather is approaching. I have seen trees with their leaves flipped which is a sign of bad weather.

One of the best videos on this subject. Very informative. Please give us more on plant husbandry as this one might need to be updated.

Amazing! I listened to Dan Killtridge do a weekend seminar and he talked about Brix readings. You taught me how really use it to the plants advantage.

I wish Grame (in his AMAZING presentation) would offer more "organic" or "natural" methods for raising BRIX as not all of us live with this sort of product availability

I have been implanting biological farming and eliminating synthetic fertilisers from coffee farms we work with in Colombia. Having a real positive impact on input costs and overall health of the plants.

Remeber that calcium and potassium are great antagonist inside a plant. Often people don't have calcium deficit but over potassium storage. Like always in nature the secret is the balance between everything.

Great discussion. Thank you so much for the enlightment!

Love it I’ve been learning in the same method for a few years now and it is the only true way to grow your own food their should be more views in this video

Wow, this is so helpful! Thank you for sharing this wealth of knowledge!

Great video!! Can this be applied to turf grass in home lawns?

Awsome stuff thank you

You lost me with 75% NH4 and 25% NO3. In nature, NH4 is turned into NO3 by microbes anyways and then absorbed by plants. NH4 is assimilated right on the root surface (directly into sugars) but in very small amounts. The problem with NH4 is that it's much more toxic to plants than NO3 (problem in hydroponics). The amount of NH4 that plant can utilize is very dependent on present conditions (temp, light, humidity...) so it's very hard to control. NH4 isn't mobile, roots have to grow into it and plants have to wait for microbes to realease it (they hold it for a long time). NH4 can also cause stretching. With NO3, which is very mobile and available, plant can immediately absorb it and even store it in vacuoles for future and use it when needed. Much better for precision feeding hydroponics which is imo the future of cheap / high quality growing. Also, there is problem with pH balance with too much NH4. From what I've seen the ratio of NO3-/NH4+ should be 80/20. I'm talking hydroponic (coco, rockwool).

Soil Food Web at the other end of the scale. well done thx

I think this is an interesting area of study. I would like to learn more, can you please link the empirical evidence to support your claims: 1:55 quantity of micro-organisms in soil is directly proportional to glucose level in leaves 6:40 applying nitrate nitrogen as a fertilizer adds nitrites to our food making the food toxic (leads to cancer)

In short I tell people you are a gardener ,your job is to feed the animals underground all else looks after itself .

When you spoke about treating a square meter at the end, you said 'spray the crop' -- so you mean spraying the leaves?? I thought fertilizers were normally placed on or watered into the soil. Consuming nutrients through leaves is not the normal way the plant feeds. Please clarify what you mean, and how fast that should be expected to affect the plants.

Sir. Can you explain in detail why fulvic acid becomes second sun for plants?

If I only use local horse poo and my own chicken poo in my compost pit....and it's open-air, am I at all likely to have nitrate nitrogen in my garden??

Who is Dr. Elaine?

If nutrient levels are less in morning and more in evening, so does that not affect the petiole reports... When should we pick petiole sample, morning or evening

Does an electric brix reader works too?

Give less water to the plants and the Brix value will be higher, at the same nutrition level. Not an exact measurment.

Beyond awesome, just ordered one.

Great video !!!!!!!! How can we make we apply N the correct way so we can increase brix ? Thanks

What tradeoffs to consider in deciding the best scale for the refractometer we purchase? I noticed that the illustration shows a 32% scale.

So when you spray to test for response are you spraying the foliage or the ground near plant ?
