I often see images (charts) in which an ideal pH is shown that plant needs for optimum nutrient absorption.
But if I look further, they are almost always charts meant for soil (like gardenplants) Sometimes you see charts for hydroponics setups but never a chart for submersed plants.
But isn't there a difference between submersed and emersed plants?
ADA states that the pH should never be lower as 6.4, otherwise it is too acidic for the health of the plant.
For example:
for an gardenplant the 'best' pH for nitrogen uptake is arround pH 6.5
for an hydroponic plant it's about pH 5.8.
Is there any info about nutrition uptake related to pH for aquatic plants in their submersed environment?
Food for thoughts
