FIGURE 4.6
ABOVE:
Soil pH affects the availability of mineral nutrients to plants. In
this chart, the wider the bar, the more available that nutrient is to plants.
As the bars become narrower, nutrient availability decreases. For pome
and stone fruit crops, both macro- and micronutrients are readily avail-
able at pH 6-7.
Raising pH
For organic production, some form of limestone or dolomite is normally used
to adjust soil pH.
