Ever wonder why some plants thrive while others just won't grow, no matter how much you water or fertilize them? The secret often lies in something you can't see: your soil's pH level.

Soil pH (0–14 scale) affects nutrient availability to plants. Most vegetables, flowers, and crops thrive in slightly acidic to neutral soil (pH 6.0–7.0). If pH is too high (alkaline) or too low (acidic), plants can’t absorb nutrients like iron or phosphorus. This leads to:

  •  Yellowing leaves
  •  Stunted growth
  •  Poor harvests

A soil pH meter helps you fix imbalances before plants suffer.

 A: For home gardens, test 2–3 times a year. For farms, test before planting and after fertilizing.

Q2: How do I use a soil pH meter correctly?
 A: Take soil from 2–4 inches deep, moisten it, insert the probe, and wait for a stable reading.

Q3: What if my soil pH is too high or low?
 A: Use lime or wood ash to raise pH; sulfur or compost to lower it.

Q4: Do I need to calibrate my meter?
 A: Yes, especially digital ones. Use buffer solutions (pH 4, 7, 10).

Q5: Can I use a water pH meter for soil?
 A: No. Soil pH meters have specialized probes for dense media.
