Talk about answering a multitude of guestions I had! Great class.

[@johnboykin3128]

Good information. Brilliant. Thanks ☺️

Hi joel,great lecture, have you a link for the ph of the elements please when applying them by foliar,thanks

[@jsuria1966]

Great Information 👍👍

[@edsjames2002]

Curious as to what happens to a plants transpiration rate whilst foliage feeding. Would it slightly drop upon application?

[@Rozenkrantzz]

Do you have the slides available?

[@atulagarwal5514]

Amazing video. Very informative. Thanks...

Fish and seaweed fertiliser, they have all minerals because thay are made from complete organisms, already in available forms.

[@pedclarkemobile]

​@@RickThePeasant indoors, the overspray and residue is unhygienic and outdoors the fishy smell will attract critters. Depending on the scale, small grow or agricultural; a bottle of concentrated trace elements mix, or big bags of dry trace mix can be dissolved on site for large scale spraying.

[@oldcountryman2795]

These pyramid charts don’t imply importance, they show relative quantity required and are more informative than your suggested alternatives.

[@xx7101]

He shows the pyramid subsequent to the barrel highlighting the significance of balances and limiting factors.

[@williamlau7179]

Why not? Showing primary, secondary & tertiary essential levels. Npk>>secondary>>>>tertiary. More detailed info from other sources. The pyramid is a simple clear good diagram.

[@larrysiders1]

Tissue Analysis is useless for Iron and Mn levels. Tissues will have high levels of oxides which aren't available for plant metabolism and protein synthesis. Only Plant Sap Analysis reveals useful information FOR ALL MINERALS. See John Kempf in Advancing Eco Agriculture KZbin Videos for Plant Sap Analysis vs. Tissue Analysis.
