Crop nutrition
Lime for acidic soils.
Agricultural lime for soil pH management on acidic ground. Start with the soil test, then select the grade for your crop, soil and spreading equipment.
Calcium for productive soil. The right application begins with a soil test and a recommendation matched to your crop, soil conditions and target pH.
Fine and granular gradesReaction rate · handling · liming value
Fine particles provide more surface area for reaction, while coarser particles break down over a longer period. Our fine and granular grades give crop advisors options for balancing reaction rate, handling and sustained liming value.
Soil pH influences nutrient availability and root development. Response depends on moisture, incorporation, soil buffering and application rate. In the alkaline and calcareous soils common to parts of the West, additional lime may not be appropriate; select amendments from your soil analysis.
How the stone is milledA mineral carrier for seed coating. A mineral coating can add weight and provide a carrier for a formulated seed treatment.
Particle size, coating uniformity, pH compatibility and handling performance are important to the finished coating. Evaluate a sample with your formulation and equipment to confirm sowing performance and seed compatibility.
Calcium supports plant cell structure, but coating performance and crop response depend on the complete treatment. Our team can provide material analysis and discuss your specification.
Documentation for your operation. Every load leaves with a certificate of analysis for the specific grade you plan to use.
We help organic and conventional operators review particle sizing, purity and processing information. Your certifier determines whether a specific input and use meet the requirements of your organic program.
Technical consultation, samples and analysis support your evaluation. Regional delivery serves Idaho, Utah, eastern Oregon, western Montana and northern Nevada.
Quality & analysisStart with your specification. Bring the requirements of your operation. We’ll help you assemble the material information for a considered decision.
- O1Your soil analysisBegin with a current soil test. Agricultural lime is for acidic soils; calcium carbonate is not a general-purpose treatment for every field.
- O2Target pH & crop requirementsSet the target with your agronomist using the crop requirements and soil conditions.
- O3Particle size & handlingSelect particle size with spreading equipment, incorporation, moisture and seasonal timing in mind.
