Put Zinc Where Rice Plants Can Find ItBy Wolf Trax
Act Early and Know if Your Fields Need Zinc
Zinc deficiencies in U.S. rice production have been well documented. To save yield through better fertilizer management in rice, it’s important to take pre-season soil samples and include zinc in your analysis.
One of the challenges for zinc nutrition in rice is that flooding results in changes to soil pH, alters biochemical reactions and can reduce the availability of micronutrients. That’s why symptoms usually appear after flushing or flooding.
Normally plants can obtain sufficient zinc nutrition from the seed after emergence, so zinc deficiencies in rice typically occurs between early vegetative stages and mid-tillering.
While it’s important to take note of deficiency symptoms in your crop, keep in mind that yield potential has already been lost by the time visual deficiency symptoms appear in the field. A zinc deficiency – whether it’s caused by soil or environmental conditions – can reduce rice yields considerably.
Field-Proven Zinc Fertilizer Management in Rice
A pre-plant application of zinc can be the most economical and effective means of providing zinc nutrition. You can do this by applying Wolf Trax Zinc DDP® with your granular fertilizer at or prior to planting. Some retailers have also coated post-emergent nitrogen applications (AN, AMS, urea) with Zinc DDP, then applied the blend with an airplane.
Formulated with EvenCoat™ Technology, Zinc DDP coats onto dry fertilizer granules. By coating every granule in a blend, farmers can apply a blanket of zinc across the field, placing zinc close to plant roots for early plant uptake.
Zinc DDP also features the PlantActiv™ Formulation, a chemical and physical design for better nutrient availability to plants. Zinc DDP’s particle size is idea for plant uptake, and the unique formulation helps the nutrients avoid soil tie-up and remain plant-available.
Field trial results from multiple years and multiple locations show how Zinc DDP is effective at providing rice crops the zinc nutrition they need:
- Plant tissue uptake of zinc increased by 21% with Zinc DDP
- Yield increased by 5% with Zinc DP
To improve your zinc fertilizer management in rice, ask your retailer to add Wolf Trax Zinc DDP to your dry fertilizer.
