SHADE OR SHADECLOTH
keeping the plant leaves below 86 degrees is important
Above that they stop doing photosynthesis and sending sugars into the soil, thus soil life weakens adn the process of building soil stops.
"When you have healthy plants they deliver more sugar and energy than you can ever hope to match with compost or any other applications.
When you increase the PS from 20 to 60% you triple the sugar production every day. Most gets sent out into root exudates, and carbohydrates. 15,000 lbs transferred from corn per acre.
Therefore the highest priority is to grow really healthy plants." JOHN KEMPF
2 PLANT MANY DIVERSE PLANTS

having a cover crop of 8+ varieties well chosen vastly improves plant performance during drought and also soil building.
3 USING SOIL INNOCULANTS
healthy plants create healthy soils far more than the other way around. It's a chicken and egg question.
4 FOLIAR SPRAYS are the most potent way to increase plant health. Strong plants with shiny green leaves handle heat stress much better.

5 WEAK PLANTS attract bugs and disease from miles around.
Bugs and disease are a symptom of weak plants. Foliars are the most powerful way to fix this.
6 See LANDRACE GARDENING, a master key. They teach the power of saving seeds that survive drought for example, and the next generation will be far far more able to hand drought and be acclimated to your area's conditions and your desires.
