Frequently asked questions

What is a sapropel biostimulant?

A sapropel biostimulant is produced from naturally occurring freshwater lake sediments rich in organic matter and biologically active compounds. Nordagri’s formulation contains humic and fulvic acids together with naturally occurring nutrients that support plant development and nutrient uptake.

What are the main benefits for field crops?

The biostimulant is designed to support root development, nutrient and water uptake, overall crop growth, and yield potential. It can also provide additional support to plants during periods of environmental stress.

Which crops can the biostimulant be used on?

The product is intended for a broad range of agricultural crops and can be incorporated into different crop management programs. The appropriate application strategy should be selected according to the crop, growth stage, and local growing conditions.

How can the biostimulant be applied?

The product can be used through several application methods, including foliar spraying, seed treatment, in-furrow application, fertigation, and drip irrigation. For large-scale field agriculture, foliar and in-furrow applications can be integrated into existing field operations.

Can it be used together with fertilizers?

Yes. The biostimulant is designed to work alongside established fertilization programs rather than replace crop nutrition entirely. It is compatible with a wide range of fertilizers and can be incorporated into existing crop management programs.

Is it compatible with crop protection products?

Sapropel biostimulant is compatible with a wide range of fertilizers, plant protection products, and plant growth regulators. Compatibility and application conditions should nevertheless be confirmed for the specific tank mix and crop program before large-scale use.

When during the growing season can it be applied?

The biostimulant can be used at different stages of crop development, beginning with seed treatment and early establishment and continuing through later growth stages. Application timing should be adapted to crop requirements and the objective of the treatment.

Why use a sapropel biostimulant in large-scale agriculture?

For broadacre farming, the main value is its ability to complement an existing crop program while supporting root development, nutrient uptake, crop performance, and yield potential. The liquid format also allows it to be incorporated into application systems already used in commercial field production.

What is sapropel?

Sapropel is a naturally occurring, fine-grained sediment that accumulates at the bottom of freshwater lakes under low-oxygen conditions. It is formed from decomposed aquatic plant and animal material combined with mineral components and can contain a significant proportion of organic matter.

How should the biostimulant be stored and handled?

The biostimulant should be stored and handled according to the technical product instructions, with the container kept properly closed and protected from unsuitable storage conditions. Before large-scale application, the product should be mixed and handled according to the recommended procedure to ensure consistent use across the field.

Is the biostimulant CE-marked?

Yes. It is CE-marked under EU Regulation 2019/1009, the EU Fertilising Products Regulation, and its effect is backed by three years of research and field trials.
