Placed with Purpose

Why Soileos Boron + Zinc Delivers Where It Matters

All nutrients only benefit the crop when they’re available in the right form, at the right time, in the right place. It sounds simple, but in practice, it’s one of the biggest challenges in fertilizer management.

This is especially true for micronutrients like boron and zinc, which are essential for healthy growth and development, yet prone to losses or inaccessibility depending on soil condition and nutrient formulations. That’s where Soileos Boron + Zinc offers a clear advantage.

Designed with Right Place in mind, this smart micronutrient fertilizer combines two critical nutrients, boron and zinc, in a unique cellulose-based formulation that holds its position in the soil profile and releases in sync with plant demand. The result? Better uptake, better ROI, and a better shot at unlocking yield potential.

The Problem with Placement

Application ≠ Availability

There’s a difference between putting nutrients on the field and ensuring they’re available to the crop. Traditional boron sources (like boric acid or sodium borate) are highly soluble and prone to leaching, especially in coarse or low-organic-matter soils. These forms can wash below the root zone long before crops need them most—during flowering, seed set, or pod fill.

Zinc poses different challenges. While less mobile than boron, zinc often binds tightly to soil particles, especially in high pH or calcareous soils, making it chemically unavailable even when present.

The result? Crops are technically “fertilized,” but still deficient and the opportunity for optimal yield and quality is lost.

Why It Matters

When availability fails, so does ROI

Yield response to micronutrients like boron and zinc is often misunderstood—not because they’re unimportant, but because their timing and placement are so critical. Micronutrient deficiencies can be silent yield killers, reducing kernel weight, grain fill, or pollen viability without obvious visual symptoms.

Poor placement risks losing nutrient dollars to leaching or fixation and also risks missing key developmental windows when crops are most sensitive to micronutrient supply.

That’s why simply applying boron or zinc isn’t enough. They must be held in the root zone and made available on the crop’s terms, not the soil’s.

The Soileos Difference

A nutrient delivery system that works with biology—not against it

Soileos Boron + Zinc uses a patented cellulose-based platform that does more than just slow-release nutrients, it stabilizes them in the zone where roots grow and ensures a gradual, crop-responsive supply. Soileos Boron and Zinc baseball card

This formulation is:

Low-leaching: Boron stays where you place it, instead of disappearing with rainfall
Bioavailable: Zinc remains accessible even in challenging soil chemistries
Microbially active: The cellulose matrix enhances rhizosphere activity, contributing to overall nutrient cycling and soil health

This combination helps address the real-world constraints that retailers and agronomists face when balancing placement, performance, and risk.

Blend Ready, Field Proven

Custom fit for custom blends

Soileos Boron + Zinc is engineered for clean, consistent blending. It flows cleanly, stores well, and doesn’t clump. Its granular format integrates seamlessly into existing dry fertilizer programs, requiring no changes to equipment or placement practices.

Designed to address two of the most persistent micronutrient challenges in prairie soils, this formulation supports both banded and broadcast applications. Its compatibility with common macronutrient sources makes it easy to incorporate into a variety of strategies—whether for fall or spring placement.

By maintaining nutrient availability in the root zone over time, it delivers a reliable solution that aligns with the principles of nutrient stewardship and supports confident decision-making in the field.
