#1 Natural High Calcium Eggshell Ag Lime
Why Our EggShell Ag Lime Material is A Better Choice
1. Superior Nutrient Profile
Our Simple Source Cal-Egg High Calcium EggShell Ag Lime is more than a liming material. Along with balancing soil pH, it offers a nutrient-rich composition, including:
- Nitrogen: ≈ 16 lbs/ton
- Phosphorus: ≈ 4.5 lbs/ton
- Potassium: ≈ 2 lbs/ton
- Sulfur: ≈ 2.5 lbs/ton
These added nutrients reduce reliance on external fertilizers, optimizing your input costs.
2. Proven Liming Efficiency
Independent tests confirm that the Effective Neutralizing Power (ENP) of our material is a close match to traditional lime, delivering immediate results in soil pH correction.
3. OMRI Listed
Suitable for immediate Organic Use.
4. Longer Lasting
Our Simple Source Cal-Egg High Calcium Eggshell Ag Lime material provides longer-lasting benefits, reducing the frequency of liming. Saving time and money.
Why Choose EggShell Ag Lime Material for your fields?
Backed by Science
- Proven Efficacy in Field Trials: The Iowa State University study demonstrated that eggshell lime is as effective as traditional agricultural lime in neutralizing soil acidity. Notably, the measured soil pH increases were 2–3 times higher than those suggested by standard ECCE calculations. Read the full study here.
- Enhanced Longevity: Research confirms that eggshell lime maintains its liming effect longer than traditional pit lime, reducing the frequency of applications and lowering long-term costs.
- Refined ECCE Calculations: The unique structure of eggshell lime—including its extensive pore structure and protein matrix—amplifies its reactivity. Correcting ECCE values, as suggested by the Iowa State study, ensures accurate application rates and avoids over-liming.
Testing Validation
Laboratory Accuracy: Standard nutrient testing underestimates ECCE values for eggshell ag lime by 2–2.5 times due to the inclusion of the protein layer. Washing the shells before testing dramatically improves ECCE measurements.
On-Farm Trials: Independent testing on our farm aligns with the Iowa State findings, further validating the superior performance of eggshell ag lime. The graph on the right shows the results of our own trial, where we applied 2.5 tons of our Simple Source Cal-Egg High Calcium Eggshell Ag Liming material and integrated it into the soil during the fall of 2023, with associated soil pH analysis. We will continue tracking and reporting the results.
Why Liming Matters - Benefits of 6.5 - 7.0 Soil pH
Proper pH through liming keeps most crop nutrients at their highest availability. As the pH moves higher than 7.4 pH or lower than 6.2 pH, the soil tends to bind up the nutrients keeping them from being available to the growing plant. The chart below demonstrates this range for different nutrients.
The chart below shows how the nutrients become more or less available as the pH increases and descreases.

How our Eggshell Ag Lime Helps Your Soil
Our organic high-calcium ag lime, derived from eggshells, offers a host of benefits for both organic and conventional farming operations:
Enhanced Soil Health and Plant Growth:
- Optimized Soil pH: Our lime effectively neutralizes acidic soils, creating optimal conditions for nutrient uptake and plant growth.
- Improved Nutrient Availability: By improving soil structure, our lime helps plants access essential nutrients like phosphorus and micronutrients more efficiently.
- Stronger Root Systems: Healthier soil leads to stronger root systems, increasing plant resilience to stress, drought, and disease.
- Increased Crop Yields: Our lime can help boost crop yields and quality.
Calcium-Rich Benefits:
- Enhanced Cell Wall Strength: Calcium is essential for building strong cell walls, improving plant structure and disease resistance.
- Improved Fruit Quality: Calcium plays a crucial role in fruit development, leading to firmer, more flavorful, and longer-lasting produce.
- Reduced Blossom End Rot: Calcium deficiency can lead to blossom end rot in tomatoes and other fruits. Our lime helps prevent this common problem.
- Reduced Chemical Fertilizer Use: Our lime can help minimize the need for synthetic fertilizers, reducing environmental impact.
- Improved Water Quality: By enhancing soil health, our lime can help reduce nutrient runoff and improve water quality.
- Carbon Sequestration: Healthy soils can sequester carbon, helping to mitigate climate change.
Cost-Effective Solution:
- Long-Lasting Effects: Our lime provides long-lasting benefits, reducing the frequency of lime applications.
- Improved Soil Fertility: By improving soil fertility, our lime can reduce the need for costly fertilizer inputs.
Whether you’re an organic or conventional farmer, our organic high-calcium lime offers a sustainable and effective solution to improve soil health, boost crop yields, and enhance fruit quality.
