Does soil fertility affect photosynthesis?
Absolutely, photosynthesis relies on Nitrogen to build cell proteins with implications on growth. Phosphates/Phosphorus are necessary for respiration and growth.
Potassium is the critical in photosynthesis, respiration, and flowering/fruiting with the second mineral being Magnesium and Magnesium compounds.
The macro-nutrients N,P and K and about 17 others are all key to overall plant health growth and efficient photosynthesis.
So yes. Soil replenishment with these three macro-nutrients (and 17 other minerals), is important for photosynthesis. A perfect example is tomato plants in one section of the garden, with a magnesium deficiency, will yield yellow leaves, a sign of chlorosis (lack of chlorophyll).
Photosynthesis
is indirectly related to soil fertility, a thin poor soil will have small poor plants, a thick rich soil will support thriving healthy plants which will as a result have more photosynthisis.
