The Calcium VIP Pathway: Smarter Nutrition for Pea Pods

Calcium is a crucial yet often misunderstood nutrient in pea production. While most growers appreciate its role in crop quality and disease resistance, delivering calcium effectively to the parts of the plant that need it most—like pods and peas—remains a challenge.

Traditional calcium fertilisation methods (soil-based and foliar) have significant physiological and practical limitations. Enter Albina from Levity Crop Science—a smart calcium product designed specifically to overcome these challenges. Through targeted delivery and superior uptake mechanisms, Albina has shown significant yield and quality gains in commercial pea trials, offering a step-change in calcium nutrition for legumes.

The Role of Calcium in Peas

Calcium provides structural support to plant cells, reinforces membranes, enhances stress tolerance, and is key in cell division and growth. In peas, calcium supports:

• Firm pod development
• Seed setting and uniform filling
• Resistance to disorders and stress (heat, cold, drought)
• Improved shelf-life and processing quality

Yet despite its importance, calcium is one of the least mobile nutrients in plants—especially when it comes to reproductive tissues like pods.

️ Why Conventional Calcium Fertilisers Often Fail

Many pea growers apply calcium through:

• Soil-applied products like lime or gypsum
• Foliar sprays using calcium nitrate or chloride

These methods do improve overall plant calcium levels but often fail to deliver calcium where it matters: developing pods and seeds. Here’s why:

1. Calcium is xylem-mobile only It moves with water flow, primarily to high-transpiring tissues like leaves. Pea pods, with lower transpiration rates, are at a disadvantage.
2. Phloem immobility Calcium cannot be remobilised once deposited. So even if a foliar spray reaches a leaf, it won’t move to the pods from there.
3. Inefficient absorption under stress In heat, cold, or drought, plant demand for calcium increases—but its uptake capacity decreases. Traditional calcium forms can’t keep up.
4. Dependence on Polar Auxin Transport. Even when calcium is delivered directly to a target tissue, its uptake and incorporation into cell walls is heavily dependent on polar auxin transport. Auxin is a plant hormone that facilitates calcium uptake into actively growing tissues, especially through regulation of membrane channel activity and cell wall plasticity.

Reproductive tissues such as pods, flowers, and peas often have low auxin levels, especially during key calcium uptake windows. This hormonal limitation means that even applied calcium may not be transported into cells or integrated into structural components like pectate-rich cell walls. This is a major barrier to correcting local calcium deficiencies in pods using conventional products.

Introducing Albina: Smart Calcium for Targeted Results

Albina from Levity Crop Science uses LoCal™ technology, which enables calcium to be absorbed and transported into tissues where conventional calcium can’t reach—even low-auxin areas like pods, flowers, and developing seeds.

✔️ How Albina Works Differently:

• Targets Low-Auxin Tissues: LoCal is a proprietary Membrane Calcium Transport Stimulant (MCAS), a mechanism scientifically proven to significantly improve calcium transport into low-auxin tissues and enhanced fruit integrity and quality under stress conditions (Dodgson et al., 2023). that bypasses the plant’s reliance on auxin for calcium uptake. This allows Albina to deliver calcium directly into cells of mature or low-activity tissues that otherwise block absorption.
• Efficient Absorption Where It Matters: Albina enables applied calcium to cross cell membranes and integrate into critical structural zones (e.g. pod walls, seed membranes), supporting firmness and resilience.
• Low-rate, high-efficiency: Just 1 L/ha per application delivers results, reducing waste and operational costs.

Proven Results: Albina in Pea Trials

In 2021–2022 trials across five commercial fields in New Zealand, Albina significantly outperformed standard grower programs:

• Average Yield (T/ha): Albina = 10.18 – 12.07, Standard = 7.16 – 9.44
• Yield Gain: +1.2 T/ha avg
• Crop Quality: Similar or better
• Time to Maturity: No difference

In our New Zealand field trials, Albina-treated pea plots consistently produced 107–121% of the yield compared to the standard, even when faced with high rainfall and low sunshine,” said the Levity Crop Science agronomy team. “This highlights how effective Albina is at supporting calcium uptake and productivity under real-world stress conditions.

Recommended Application for Peas

For best results in field peas:

• 2 applications at 1 L/ha:

This aligns with the critical calcium uptake window—where 80% of pod calcium is accumulated.

Final Thoughts

Peas are particularly vulnerable to hidden calcium deficiencies in pods and seeds—even when soil and leaves test adequate. Conventional calcium strategies don’t address this. Albina does.

Backed by rigorous trials and real science, Albina offers pea growers a low-input, high-impact solution to unlock better yield, quality, and crop resilience.

If you’re looking to modernise your calcium strategy for peas, Albina is the clear next step.
