AgConcepts Application Rate Reference Chart
Complete application rate reference for all AgConcepts products across major crops, application methods, and timing — a quick-reference guide for the field.
How to Use This Reference
This chart provides standard application rates for all AgConcepts products available through BulkFarmer. Rates are given for four application methods: soil broadcast, foliar spray, in-furrow placement, and fertigation (irrigation injection). These rates represent the standard starting point — your agronomist may recommend adjusted rates based on soil tests, crop history, and specific field conditions.
All rates are expressed in quarts per acre (qt/acre) or ounces per acre (oz/acre) as noted. Products labeled with oz/1,000 seeds are seed-applied products where the rate is based on seed volume rather than land area.

Compatibility Notes
All AgConcepts products are compatible with UAN (28-0-0, 32-0-0), AMS, and most liquid micronutrient packages. Always perform a jar test when introducing a new combination. Avoid mixing with copper sulfate at high rates (copper can suppress biological activity). Phosphoric acid (used for pH adjustment) is generally compatible at typical buffering rates.
