How does Ph of soil affect plant gr0WTH ??

IM USING STATICE ASTER %26amp; PANSY SEEDS . FOR SOIL I USED SAND , POTTING SOIL, %26amp; GROUND SOIL.





I NEED HELP WHAT AM I SUPPOSED 2 DO WITH IT ?? WHAT IS MY CONCLUSION

How does Ph of soil affect plant gr0WTH ??
A little question requiring a very large answer. If this assignment is due soon, I would use radish or navy bean seeds, very quick germination. You also need to be able to check your pH, ask your teacher or buy an inexpensive kit of your own from a big box store. Sand should have a pH close to whatever your waters pH is. Potting soil should be in the range quoted by T-bone, 5.5-6.5. Garden soil will be unknown until you test. RScott
Reply:It affects the plant's ability to take up nutrients from the soil. There can be plenty of nutrients available, but if the pH isn't right then the chemistry of the plant won't work correctly. Eventually the plant will probably die. You can tell the kind of nutrient deficiency by looking at the kind of discoloration in the leaves:


Here's a link to a very good explanation:

Reply:pH generally affects what nutrients are available to the plant. If pH is too high or low, nutrients such as iron, magnesium etc may be present in the soil, but the plant won't be able to access them. They'll be 'locked up', so to speak.


Ideal pH for most plants usually rests between 5.5 and 6.5





I don't understand your question - is this an academic project of some type?
