Agronomical & NPK Comparison

Chicken Manure vs Next-Gen Fertilizer

This page provides an agronomical and nutritional comparison between traditional chicken manure pellets with NPK of 4-3-3 and our next-generation organic fertilizer BASE 4-4-4.

Not to claim that one solution fits all situations, but to show where each product performs best, and where its limitations lie.

We believe that honesty builds long-term trust. By sharing more technical data than is common in the market, we enable informed decisions.

Parameter	Chicken Manure Pellets	BASE 4-4-4	Practical takeaway
Raw material	Chicken manure (layers)	Animal manure and selected plant-based materials	Both use circular organic inputs; BASE 4-4-4 is produced from a broader mix of raw materials
Granule size (mm)	4–5	4–5	Comparable handling, size and shape of product
Dry matter (%)	85–90	85–90	Similar dry matter content and logistics
Organic matter (%)	60–65	62	Both contribute to long-term soil health
Total nitrogen (N, %)	4.0	4.4	Slightly higher total nitrogen content in BASE 4-4-4
Phosphate (P₂O₅, %)	3.0	3.7	Higher phosphorus content in BASE 4-4-4
Potassium (K₂O, %)	2.5	3.5	Higher potassium content in BASE 4-4-4
Calcium (CaO, %)	6–9	2.8	Chicken manure typically supplies more calcium
Magnesium (MgO, %)	1	2	Higher magnesium contribution in BASE 4-4-4
Sulphur (kg/ton)	0.5–1.2	0.38	Chicken manure generally has a higher sulphur content
Essential trace elements (Mn, Fe, B, Co, Cu, Zn)	Average content	High content	BASE 4-4-4 contains a broad range of trace elements supporting various plant processes
Sodium (Na₂O, %)	0.3–0.9	0.8	Sodium levels in BASE 4-4-4 are generally higher compared to chicken manure pellets
Chloride (Cl, %)	0.2–0.7	0.75	BASE 4-4-4 may be less suitable for highly chloride-sensitive crops
pH	6.8–7.2	7.5	BASE 4-4-4 has a slightly higher pH
Best fit crops	Vegetables, greenhouse crops, high calcium-demanding crops	Open-field crops, vegetables, fruit crops, cost-efficient fertilization	Crop requirements and fertilization strategy determine the optimal choice
Limitations	Lower nutrient density per ton, limited supply, more costly	Higher sodium and chloride levels should be considered for sensitive crops	No organic fertilizer is universal; crop, soil conditions and application rate matter
