Dual Source Protein Fertilizer: Protein + Fulvic

Name: Dual Source Protein Fertilizer
Brand: Seadom

Dual Source Protein Fertilizer – Protein-Rich Granule with Biochemical Fulvic Acid

Dual Source Protein Fertilizer pairs a high crude protein fraction with a strong biochemical fulvic acid component: the declared specification calls for biochemical fulvic acid ≥45% (dry basis), free amino acid ≥15%, organic matter ≥37% and total primary nutrients ≥10%. In the reference batch analysis, crude protein measured 49.55% and moisture came in at just 1.15%.

Nutrient Composition

The declared values for our standard grade:

Biochemical fulvic acid ≥45% (dry basis) – keeps nutrients mobile and available in the root zone.
Free amino acid ≥15% – absorbable peptides for rapid uptake and stress recovery.
Organic matter ≥37% – feeds soil biology and improves structure over time.
Total primary nutrients ≥10% – N ≥6%, P2O5 0–1%, K2O ≥2% — a nitrogen-led base for vegetative growth.
Crude protein 49.55% – reference batch result; a dense slow-release protein reserve.

The reference batch analysis also confirms low moisture (1.15%) and low chloride (0.56%), with heavy-metal screening per Chinese fertilizer standards: mercury and cadmium not detected, arsenic 0.5 mg/kg, lead 0.2 mg/kg, chromium 1.9 mg/kg. Full batch certificates accompany every shipment on request.

Benefits for the Field

Protein-led nutrition – a high crude protein fraction provides sustained organic nitrogen for leafy and vegetative stages.
Fulvic-driven efficiency – the biochemical fulvic acid fraction helps the crop make better use of applied nutrients.
Soil building – ≥37% organic matter supports microbial activity and long-term soil structure.
Clean specification – low moisture and screened heavy metals simplify import documentation discussions.

How It Is Applied

Soil broadcasting – spread evenly across the field before planting or between rows.
Band application – apply in rows or around the root zone during key growth stages.
Top-dressing – supplement the programme through the growing season.

Manufactured by Qingdao Seadom — a seaweed and biostimulant fertilizer manufacturer with over 35 years of experience, exporting to buyers in more than 40 countries with an annual capacity of 3,000–5,000 tonnes.

Dual Source Protein Fertilizer — frequently asked questions

What does “dual source” mean for this grade?

The grade pairs two nutrient fractions in one granule: a crude-protein-rich organic fraction (49.55% in the reference batch) and a biochemical fulvic acid fraction of ≥45% on a dry basis, backed by free amino acid ≥15% and ≥10% total primary nutrients.

How is Dual Source Protein Fertilizer applied?

Soil broadcasting, band application or top-dressing. The granular form suits soil programmes where a sustained protein-backed nitrogen supply is needed. The right rate depends on the crop, the growth stage and the application method — send us your crop and method and we will return the recommended rate for this grade.
