Diammonium phosphate N10:P20:K20+4S is a balanced mineral fertilizer with an even content of essential nutrients — nitrogen, phosphorus, and potassium — in a 10:20:20 ratio, as well as 4% sulfur in an easily available sulfate form.
The formula provides comprehensive nutrition for crops at all stages of vegetation:
- Nitrogen (N) - stimulates the growth of vegetative mass;
- Phosphorus (P₂O₅) - promotes the development of the root system;
- Potassium (K₂O) - increases resistance to drought, frost and disease;
- Sulfur (SO₃) — enhances nitrogen absorption and improves protein metabolism.
Recommended use:
- for base, pre-sowing, and in-row application;
- for all main crops: grain, industrial, vegetable, oilseed, fodder;
- especially effective on chernozems, sod-podzolic and sandy soils.
Advantages:
- universal formula N:P:K = 1:2:2 - for most crops;
- sulfur — improving product quality: protein, gluten, oil;
- granular form - precise and uniform application;
- mild effect on the soil - does not cause salinization;
- compatible with most agricultural technologies - suitable for traditional, local, strip application.
Limitations and warnings:
- do not store near acids, alkaline reagents or organic fertilizers;
- avoid moisture and direct sunlight during storage.
Appearance and сolor: irregularly shaped granules with a characteristic odor
