NANO DAP

The key difference is particle size and application method. Nano DAP contains ultra-fine particles (below 100 nanometers) that can be absorbed directly through plant leaves. Traditional DAP is a granular soil fertilizer that suffers from severe phosphorus fixation losses.

When traditional DAP hits the soil, 70-85% of the phosphorus binds with soil minerals and becomes unavailable to plants. Nano DAP bypasses this entirely through foliar application, achieving over 90% nutrient efficiency.

Many Australian agricultural soils are alkaline (high pH), which dramatically increases phosphorus fixation. When DAP granules dissolve in alkaline soil, phosphorus rapidly combines with calcium to form insoluble calcium phosphate compounds.

This chemical reaction happens within hours or days of application. You're essentially paying premium prices for phosphorus that gets locked away before your crops can use it. Nano DAP solves this by delivering phosphorus directly to leaves, completely avoiding soil chemistry.

Due to the superior efficiency, you'll need significantly less product. Many farmers report reducing their phosphorus inputs by 50% or more while maintaining or improving yields.

Start with 2-3 foliar applications at 2-3 mL per liter of water, applied at critical growth stages. Monitor your crop response and adjust accordingly. The exact reduction depends on your soil type, crop, and current phosphorus fertility levels.

Yes, Nano DAP is suitable for all crop types including cereals, pulses, oilseeds, vegetables, fruits, and horticultural crops. Phosphorus is a fundamental macronutrient required by all plants.

It's particularly beneficial for crops with high phosphorus demands like legumes, canola, and fruiting vegetables. Also excellent for crops grown in alkaline soils where traditional DAP performs poorly.

Apply during periods of high phosphorus demand: flowering stages, fruit set, and grain fill. These are critical phases when phosphorus directly impacts yield and quality.

For best absorption, spray during early morning (before 10 AM) or late evening (after 4 PM) when temperatures are moderate and humidity is higher. Avoid spraying in extreme heat or just before rainfall.

Store in the original sealed container in a cool, dry place away from direct sunlight. Keep between 4°C and 50°C. The product may freeze below 0°C but will return to normal consistency once thawed.

Always shake the bottle vigorously before use to ensure uniform particle suspension. The product has a 24-month shelf life from manufacture date when stored properly. Much easier to store than bulk bags of traditional DAP.

For soils with very low phosphorus levels, you may still want to apply some basal fertilizer. However, Nano DAP can significantly reduce or potentially eliminate this requirement over time as soil phosphorus levels build.

Many farmers use a combination approach: reduced basal application plus strategic Nano DAP foliar sprays. This provides both residual soil phosphorus and immediate plant-available phosphorus when needed most. Conduct soil tests to optimize your program.
