PH & Soil ?

[doniboy]

Two part question. Does the PH of my soil matter if the PH of the runoff after adding feeding is good? Also, if I say my soil's PH is 5, can I simply raise the PH of my nute and watering to offset it?

IMO in order to get accurate ph reading of your soil you need to get a sample of it in some distilled water.


Www.getbluelab.com

This website has a section dedicated to pH and EC values of medium.


Runoff pH can appear whacky for this reason.


The process involves distilled water, stewing time, straining and then testing the left over liquid.


Soil pH meters give you a reading that's somewhere near but runoff is not a sure fire way of testing.


In theory yes you can increase feed pH to compensate.

Yes i have a soil test kit, but was wondering for example that if the soil tested low, but the runoff was good, are my plants okay? Basically I'm asking how do if I should adjust the PH of my water/nute to offset a high soil PH?

Other than adding some peat for a high pH prob or dolomite lime for a low pH prob then the only other thing you can do is adjust your watering pH accordingly to compensate.


Most plants can still grow in ranges 4-8ph obviously the issue you have with this is nutrient uptake pH ranges which differ element to element.

If you are trying to correct a low pH issue then obviously increase your feed pH and vice versa.

Some fertilizers are designed for soil. They are buffered to maintain a more neutral pH.

which ones?

Advanced Nutrients Perfect pH line, be prepared to pay for it though.

They are not so much designed for soil, but rather designed to maintain the proper ph range of a nutrient solution. That doesnt mean its going to correct your soils PH.
