In the case that the soil becomes too alkaline, you also need to apply measures to bring the pH level down. You can do so by making use of any of the following materials: 1  Coffee grounds. 2  Cottonseed meal. 3  Lemon peels. 4  Some fertilizers. 5  Composted leaves. 6  Leaf mold.

1. Collect samples of the soil and take it to a local cooperative extension service office for testing before you add any amendments. You can also opt to use a commercial soil test kit. Test the soil in the fall. Use the test results to determine whether the soil's pH needs to be raised, and by how many points.

The sour/acid vs. sweet/alkaline balance of your garden soil is measured on a pH scale, which indicates potential hydrogen ions available to help plants process soil nutrients. Soil balance determines which plants will grow well in your yard.

Soil Formation. Using natural materials to change the pH balance of your soil accomplishes several goals for your garden. Natural materials are the basis for soil originally, which means that additional materials are easily absorbed.

You don't need to worry about pH when growing organically if you've set things up properly, unless you notice actual pH problems with your plants. View pictures of marijuana nutrient problems. pH management is much less important when growing organically than with other methods for growing marijuana.

Commercially Available Natural Options. Two chemicals found in raw form can be included in natural soil amendments and are a measurable, effective way to change pH. For both, producers offer guidance on quantities to use for specific pH results.

Lowering Soil ph Level. Mixing 1 cup of fine dolomite lime per cubic foot of soil is one of the easiest ways to stabilize the pH of the soil. Or you can use the ratio, 1 ounce of dolomite lime to 1 gallon of planting soil is best to stabilize pH level. Dolomite lime can be obtained from garden nurseries.

It will take more amendments to change the pH of organically rich soils, although the changes can also be expected to be more stable. Additional benefits from natural amendments are an increase in water-absorbency and drainage, changes to soil texture supporting root development and added microbial activity.

Dolomite Lime as a Stabilizing Ingredient. Mixing 1 cup of fine dolomite lime per cubic foot of soil is one of the easiest ways to stabilize the pH of the soil. Or you can use the ratio, 1 ounce of dolomite lime to 1 gallon of planting soil is best to stabilize pH level.

2. Spread crushed limestone over the soil. For every half point you wish to raise the soil's pH, apply the limestone at a rate of 2 pounds per 100 square feet for sandy soils, 3 1/2 pounds per 100 square feet for loamy soils and 5 pounds per 100 square feet for clay soils. Mix the amendment material into the soil.
