Aerated soils
Are highly fertile soils good?
No, it can cause excessive growth
why is excessive growth bad?
poor aeration to canopy, poor spray penetration, increased disease pressure, poor sunlight penetration
Highly fertile soils are not good in cool climates bc…
produce vigorous vines which will delay ripening
what climate is coarse well drained soils good in?
cool
Why avoid windbreaks
can cause frost pockets
