Precision Nutrition. Maximum Efficiency.
River Valley Ag Exchange offers a complete line of liquid fertilizer solutions engineered for efficiency, crop safety, and biological compatibility. Our starter and liquid fertilizer products deliver essential nutrients exactly when and where crops need them most — supporting strong early growth, optimizing yields, and working alongside biological programs.
Our premium formulations include seed-safe options for in-furrow application, versatile products for sidedress and broadcast programs, and specialized foliar fertilizers for mid-season nutrient correction. All products are formulated to mix well with biologicals, enhancing overall program performance while reducing total upfront costs.
We believe in feeding soil biology first. Our liquid fertilizers complement biological programs by providing readily available nutrients that support both plant growth and microbial activity. This approach builds soil fertility over time while maintaining high yields.
Highly available potassium, micronutrients, carbon source. Improves grain fill, test weight. Multiple foliar applications.
Readily available potassium for in-furrow, row support, or sidedress.
For soybeans, improves standability, branching, and yield. Great potassium, boron, and nutrients source.
Increases root growth and nutrient uptake efficiency. Improves grain fill. Versatile biological mixer.
Mid-season foliar nitrogen with micronutrients for wheat and corn. Boosts yield and test weight.
Slow-release foliar nitrogen jumpstarting plants during stress. Stimulates ear row setting, increases root mass.
Seed-safe for in-furrow and sidedress. Balanced NPK for corn, soybeans, wheat. Won’t salt out like other phosphorus products.
For 2×2, 4×4, sidedress, or streaming. Not for in-furrow.
Seed-safe for in-furrow and sidedress. Readily available phosphorus and potassium.
Economical nitrogen plus sulfur. Soil-applied or streamed. Not for in-furrow.
Yes. Most RVAE fertilizers are formulated to be biologically compatible. Products like 8-27-3, 3-18-18, Foundation K, and BricK work exceptionally well with biologicals.
Both are seed-safe in-furrow options. 8-27-3 provides more nitrogen and phosphorus, ideal for high-yield corn programs. 3-18-18 offers balanced P and K, excellent for soybeans and balanced fertility programs.
No. 32-0-0 should be placed 2×2, 4×4, or applied as sidedress/streaming. Direct seed contact can cause injury.
Timing depends on crop needs. BricK works well from V6 through reproductive stages for grain fill support. Pro-N is excellent for mid-season nitrogen boosts on wheat or corn (V8-VT).
Some formulations are organic-approved. Contact us for specific product certifications and organic program recommendations.
