Rain water, tap water and ground water ..... what is the BEST for plants?

Question

what is best for plants? is it rain water, tap water and ground water? explain please...... what element, substance or compund that the water has?

Answer 1

Rainwater is still the best, provided you are not in an area with high acid rain concentrations.

Plants need nitrogen. Usually it is provided by fertilizers you apply to the soil, or naturally by bacteria decomposing material in the first few inches of soil. But, there is another very important source of nitrogen for plants, RAINWATER.

When lightning strikes, the electrical activity in the air "FIXES" atmospheric nitrogen. This means that it changes the form of the nitrogen so that plants can easily absorb the nitrogen and use it in their "bodies". Nitrogen is present in the environment in numerous forms, and a plant cannot use the nitrogen until it is "fixed" by some natural process like bacteria, lightning, or fungus.

So, because lightning usually happens when it rains, the "fixed" nitrogen is washed out of the atmosphere by the rain and lands on the plants and on the soil around the plants where the roots are. Thus rainwater is the best for your plants.

Answer 2

It kind of depends on where you are. Not all rain, tap, or ground waters contain the same nutrients, chemicals, or pollutants.

If you live in LA, rainwater is probably worse than the tap water, due to the sulfuric acid. What's in your ground water? How is your area's tap wate treated?
If none of this sounds familiar to you, then it probably doesn't matter which water you use- just don't use deionized water (it lacks ions)... And too hard or soft water could be problematic depending on the species you are growing. For that mater, not all plants like the same water quality...

Answer 3

Rain water is the best. I don't know why, but after even a slight rain my plants always thrive. I've heard it's because there's nitrogen in rain water but I don't buy that. I don't think nitrogen would act so quickly.
If you have acid rain, rain water will not be the best.
Tap water usually contains chlorine, which may inhibit growth, but its generally ok.
I've never used ground water, but provided its clean, it could be super. Plus ground water might contain nutrients not found in other waters.

Answer 4

Oh my dear you are so right rain is much better than tap water Why ? Because rain water is naturally soft but tap water has been treated with so ,much chemical that it make the water harder

Answer 5

Honestly, it won't matter. Just don't use much softened water. If you live in the country tap water is ground water. If you live in the city tap water is often well (ground) water with chlorine added. The chlorine level is low enough that it's rarely a problem for plants.

Answer 6

ground water is in the soil and rain water comes naturally and tap water is very important

Answer 7

I can't give you the element, substance or compound of rainwater, but that is the ultimate best~the plants, shrubs and trees seem to thrive immediately with that~
elements, compounds and substance would vary as to where you live and whether you use well water or city water etc:

Answer 8

ground water because rain has some wastes like CO2 etc. & tap water has metallic wastes like lead etc. ground water is absolutely pure .

Answer 9

Tapwater is bad for plants because it is most likely to contain substances which are harmful. I don't know whether rain or groundwater is best though.

Answer 10

rain water.its not affected by anything
