Understanding your soil pH results is key to making informed decisions on soil amendments and fertilization. Here are some tips to interpret your soil pH results:
pH 0-5.5: Acidic soil, add lime to raise pH.
pH 5.6-6.9: Slightly acidic to neutral soil, most plants will grow.
pH 7.0-8.4: Neutral to slightly alkaline soil, add sulfur to lower pH.
pH 8.5-14: Alkaline soil, add sulfur to lower pH.
Now you know the ranges, you can take action to correct soil pH and create a perfect growing environment for your plants.
Adjusting soil pH requires careful consideration of the type and amount of amendments needed. Here are some tips to adjust your soil pH:
Raise pH: Add lime or dolomitic limestone to raise pH. These will neutralize soil acidity and provide calcium and magnesium.
Lower pH: Add sulfur or peat moss to lower pH. Sulfur is converted to sulfuric acid by soil bacteria which acidifies the soil, peat moss helps improve soil structure and lower pH.
Monitor pH: Test soil pH regularly to ensure you are in the desired pH range. Continuous monitoring allows you to adjust on time and maintain optimal soil condition for plant growth.
Now you can manage your soil pH and have healthy plants.
