Miller Nutri-Leaf 20-20-20 + ME 2.27kg: Water Soluble Foliar and Drip NPK Fertiliser

Nutri-Leaf 20-20-20: A Balanced Water Soluble Fertiliser for Foliar and Drip

Miller Nutri-Leaf 20-20-20 + ME is a balanced, water soluble NPK fertiliser designed for both drip irrigation at the root zone and foliar spraying for absorption through the leaves. It contains 20% nitrogen, 20% phosphorus (as P₂O₅) and 20% potassium (as K₂O), plus a package of minor elements (ME): magnesium, boron, copper, iron, manganese, molybdenum and zinc, with the key trace elements EDTA chelated. This 2.27kg bag suits vegetable growers, nurseries, orchards and keen gardeners feeding through a sprayer or drip system.

What Does 20-20-20 + ME Mean?

• 20-20-20: equal parts nitrogen, phosphate and potash, for all-round growth.
• ME (minor elements): trace elements added alongside the main nutrients.
• EDTA chelated: the key trace elements are bound in a chelate, which keeps them available for plants to absorb, even in soils where they'd otherwise get locked up.

Australian fertiliser labels usually show phosphorus and potassium as elements rather than oxides. Converted, 20-20-20 equals roughly 20% N, 8.7% P and 16.6% K. That makes Nutri-Leaf higher in phosphorus than many Australian general-purpose soluble fertilisers.

Which Fertiliser Can Be Used as a Foliar Spray?

A foliar fertiliser needs to dissolve completely, so it can be sprayed and absorbed through the leaves. Nutri-Leaf is made for this. When sprayed onto leaves, nutrients enter through the leaf surface and tiny pores called stomata, giving a fast boost. Foliar feeding is especially useful when roots are struggling, such as in waterlogged or cold soil, or when nutrients in the soil are locked up. It works alongside soil feeding, not as a full replacement.

How to Use Nutri-Leaf as a Foliar Spray

• Dissolve the powder completely in clean water. As a general guide for knapsack sprayers, about 6g per litre is used. Check the label for your crop.
• Spray in the early morning or late afternoon, when it's cool and the leaf pores are open.
• Avoid spraying in direct hot sun, which can scorch leaves.
• Mist both the upper and lower leaf surfaces until just wet.
• Repeat through the growing season as your crop needs.

How to Use Nutri-Leaf Through Drip Irrigation

• Dissolve the powder completely before adding it to your fertigation tank or injector, to prevent blocked drippers and emitters.
• Fit injectors or mixing tanks upstream of pressure regulators in automated systems.
• Flush the lines with plain water after each fertigation cycle to clear leftover salts.

Which Water Soluble Fertiliser Is Best?

The best water soluble fertiliser depends on the plant and growth stage. A balanced 20-20-20 suits general growth across vegetables, fruit, flowers and ornamentals. Higher nitrogen formulas suit leafy growth, and higher potassium formulas suit flowering and fruiting crops. Avoid high-phosphorus fertilisers like this on phosphorus-sensitive natives such as grevilleas and banksias.

Tank Mixing

Nutri-Leaf is compatible with most commonly used pesticides. Always do a small jar test first and follow both product labels before tank mixing.

Frequently Asked Questions

What is Miller Nutri-Leaf 20-20-20 + ME?

It's a balanced, water soluble NPK fertiliser with chelated trace elements, designed for both drip irrigation and foliar spraying.

What does the ME in Nutri-Leaf 20-20-20 mean?

ME stands for minor elements. It means the fertiliser includes trace elements, such as magnesium, boron, iron, manganese and zinc, as well as the main NPK.

What is a water soluble fertiliser?

It's a fertiliser that dissolves completely in water, so it can be applied through a sprayer or irrigation system and taken up quickly by roots or leaves.

Which fertiliser can be used as a foliar spray?

Fully water soluble fertilisers made for foliar use, like Nutri-Leaf, can be sprayed onto leaves. Dissolve completely and spray in the cool of the day.

How much Nutri-Leaf do I mix per litre?

As a general guide for knapsack spraying, about 6g per litre of water. Rates vary by crop and growth stage, so check the label.

Can I use it through drip irrigation?

Yes. Dissolve it fully before injecting, and flush lines with clean water after each cycle.

Is Nutri-Leaf suitable for Australian natives?

Not for phosphorus-sensitive natives such as grevilleas, banksias and other Proteaceae, as it's relatively high in phosphorus. Use a low-phosphorus native fertiliser for those plants.
