#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. You get $8.00 in added nutrient value with our high calcium eggshell ag lime material.
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 by a couple of years. Saving time and money.
Why Choose EggShell Ag Lime Material for your fields?
Backed by Science
- Proven Efficacy in Field Trials: Iowa State University conducted a study to determine the effectiveness of eggshells as a liming agent. The 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 which holds the shell together. Washing the shells before testing dramatically improves ECCE measurements. In actual practice, the soil biome breaks down the protein layer similar to washing.
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. The graph shows the increases in soil pH during the first year. 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 decreases. (shown as a thin/less available or thicker/more available line)
