Introduction

This tutorial provides a step-by-step guide on soil treatment principles before planting, focusing on increasing soil pH and incorporating calcium (Ca) and magnesium (Mg) through specific methods. Understanding these practices is essential for successful farming and crop production.

Step 1: Prepare Dolomite Solution

To enhance soil pH, you can use agricultural lime, specifically dolomite, which contains both Ca and Mg.

1. Gather Materials:

   • 30 kg of dolomite
   • 200 liters of water

2. Mixing:

   • Combine the dolomite with water in a large container.
   • Allow the mixture to ferment for a specified duration (follow local guidelines for fermentation time).

3. Extraction:

   • After fermentation, strain the mixture to separate the liquid from the solid sediment.
   • Use only the clear liquid, discarding any sediment remaining at the bottom.

Step 2: Apply Dolomite Solution

Once you have your dolomite solution ready, it’s time to apply it to your soil.

1. Application Method:

   • Use a sprayer or watering can to evenly distribute the dolomite solution across the targeted soil area.
   • Aim for a uniform coverage to ensure even pH adjustment.

2. Timing:

   • Apply the solution at least a few weeks before planting to allow the soil to absorb the nutrients.

Step 3: Utilize Earthworm Enzymes

An alternative method to enrich your soil with Ca and Mg is through the use of earthworm enzymes.

1. Obtain Earthworms:

   • For every hectare of land, use approximately 100 kg of earthworms.

2. Incorporate Earthworms into Soil:

   • Introduce the earthworms into the soil where you plan to plant.
   • Ensure that the earthworms are evenly distributed to maximize their beneficial effects.

3. Benefits:

   • Earthworms help aerate the soil and enhance nutrient availability, contributing to healthier crop growth.

Step 4: Monitor Soil pH Levels

After application of dolomite or earthworm enzymes, it’s crucial to monitor soil pH levels.

1. Testing:

   • Use a soil pH testing kit to check the pH levels of your soil periodically.
   • Adjust the application of dolomite or earthworms based on the pH test results.

2. Adjustment:

   • If pH levels are still low, consider reapplying the dolomite solution or increasing earthworm population in the soil.

Conclusion

By following these steps to prepare and apply dolomite and utilize earthworm enzymes, you can effectively increase your soil's pH and nutrient content. Regular monitoring of soil pH will help you make necessary adjustments and ensure optimal conditions for planting. For best results, integrate these practices into your overall soil management strategy.
