Two farmers in a tomato field discussing crop management, highlighting liquid fertiliser use for higher fruit yields and healthy crops.

Nu-Actu8™ Cal + B

Nu-Actu8™ Cal + B is a premium foliar fertilizer designed to provide calcium and boron, two essential nutrients for plant health. Calcium is critical for cell wall integrity and fruit development but has low mobility within plants, often leading to deficiencies. Boron, included as a cofactor, enhances calcium uptake and addresses boron deficiencies. The unique chelated amino acid complex ensures rapid absorption and transport, with nutrients delivered precisely where they are needed.

Crop Types

Analysis

  • Calcium (Ca): 6.7% w/v
  • Boron (B): 0.2% w/v

Purpose

Supplies calcium and boron to enhance plant and fruit development, correct deficiencies, and improve nutrient uptake.

Key Value

High-efficiency chelated amino acid complex combining calcium and boron for superior absorption and transport.

Benefits

  • Fully water-soluble, leaving no residue on leaves.
  • Electrically neutral chelation allows nutrients to diffuse easily through cell walls.
  • Reduces plant energy expenditure on nutrient metabolism, supporting better growth.
  • Highly mobile nutrients quickly transported to critical areas.
  • Corrects calcium and boron deficiencies, improving fruit quality and yield.

Usage

  • Suitable for row and tree crops.
  • Best applied during targeted growth stages or as needed to correct deficiencies.

Application Rate and Timing

  • Apply 1-3 times at 2-5 litres/ha as a foliar spray.
  • Recommended for use before flowering and during early fruit set, especially in cold winters or low humidity conditions.

The Nu-Actu8™ Range

Foliar nutrition, redefined from the inside out.

The Nu-Actu8™ Range isn’t just a foliar fertiliser—it’s a new way to deliver what plants need, exactly where they need it. This technology steps beyond traditional foliar products, using a refined molecular structure that allows nutrients and amino acids to move seamlessly into the plant. By blending essential elements with amino acids and NESA’s proprietary delivery system, Nu-Actu8™ creates a fast-tracked pathway for absorption. That means less energy wasted, quicker uptake, and a higher return on every application. When timing is everything and conditions can’t be controlled, efficiency makes all the difference. With Nu-Actu8™, every spray works harder to support crop performance when it counts most.

FAQ

Why combine calcium and boron in Nu-Actu8™ Cal + B?

+

Nu-Actu8™ Cal + B combines 6.7% calcium with 0.2% boron because boron acts as a cofactor that enhances calcium uptake and mobility. This premium foliar fertiliser addresses calcium's low mobility within plants while simultaneously correcting boron deficiencies for improved fruit development and quality.

When should I apply Nu-Actu8™ Cal + B for maximum effectiveness?

+

Apply Nu-Actu8™ Cal + B 1-3 times at 2-5 litres/ha before flowering and during early fruit set, especially in cold winters or low humidity conditions. This timing ensures optimal calcium and boron availability during critical development stages when deficiencies commonly occur.

How does the chelated amino acid complex improve nutrient uptake?

+

The electrically neutral chelation in Nu-Actu8™ Cal + B allows nutrients to diffuse easily through cell walls while reducing plant energy expenditure on nutrient metabolism. This advanced foliar technology ensures rapid absorption and transport of both calcium and boron to critical plant tissues.

Which crops are most susceptible to calcium and boron deficiencies?

+

Tomatoes, capsicums, stone fruits, and pome fruits are particularly susceptible to calcium deficiencies (blossom end rot, bitter pit), while many crops including tree nuts and fruits require adequate boron for pollination. Nu-Actu8™ Cal + B provides comprehensive nutrition for these Australian farming applications.
