NP 20:20+13s (Sulphoammophos), Agropolychim

Agropolychim is a leading Bulgarian producer of mineral fertilizers, supplying its products to more than 40 countries. The plant is certified according to ISO 9001, ISO 14001, and ISO 45001, with quality control carried out at every stage — from raw materials to packaging.

Sulphoammophos 20 20 13 is applied both as a base and starter fertilizer. It works especially well on soils poor in phosphorus and sulfur, ensuring even root development, increased plant stress resistance, and stable crop formation.

Advantages of Sulphoammophos NP 20:20+13s from Neuron

The excellent quality and high efficiency of this fertilizer are ensured primarily by its optimally balanced composition. Key advantages of Sulphoammophos 20 20 13 include:

• Balanced nutrient composition: 20% nitrogen, 20% phosphorus, and 13% sulfur. This formula covers the main plant needs without excess or deficiency.
• Two nitrogen forms — ammonium and nitrate — provide both quick action and long-term feeding. Ammonium is absorbed more slowly, reducing nitrogen losses from leaching, while nitrate supplies nitrogen rapidly during growth peaks.
• High sulfur content (13%) is one of the main advantages. Sulfur plays a vital role in protein synthesis, enzyme reactions, and nitrogen utilization. It boosts plant resistance to diseases, improves yield quality, and supports root development.
• Fast nutrient uptake due to optimized granulation and physicochemical properties.
• Economic efficiency — the concentrated composition allows reduced application rates, lowering fertilizer and logistics costs.
• Compatibility with other fertilizers and the possibility of combined application with micronutrients for complete feeding.
• Compliance with international quality standards and certification ensuring safety and efficiency.

These advantages make Sulphoammophos NP 20:20+13s a universal fertilizer for different climates and soil types.

Application of Sulphoammophos NP 20:20+13s for Different Crops

The balanced composition allows effective use of Sulphoammophos for a wide range of crops. Below are the main groups and application specifics:

Sunflower

For sunflower, Sulphoammophos is considered one of the most effective fertilizers. Nitrogen and phosphorus support intensive early growth and strong vegetative mass, influencing reproductive organ formation. Sulfur increases oil content and disease resistance.

Application under sunflower helps to:

• Increase seed mass and quality.
• Boost stress resistance (drought, pests).
• Improve overall crop productivity.

It is recommended to apply before primary tillage and as early top dressing.

Rapeseed

Rapeseed requires quality nitrogen, phosphorus, and sulfur nutrition, especially during leaf formation and budding stages.

Sulphoammophos helps to:

• Improve plant growth and development.
• Increase pod set and quality.
• Raise oil content and yield.

Application improves cold and disease resistance, crucial for winter varieties.

Winter Wheat

For winter wheat, Sulphoammophos supports spring regrowth and strong tillering. Nitrogen promotes shoot growth, phosphorus strengthens roots, and sulfur improves disease resistance and grain quality.

Fertilizer use helps to:

• Ensure reliable regrowth after winter.
• Improve grain quality and protein content.
• Increase yield.

Applied before tillage or as spring top dressing.

Wheat

For wheat, Sulphoammophos is a key nutrient source throughout the growing season, supporting plant growth, improving grain structure, and enhancing stress resistance.

Watermelons and Melons

For melons — watermelons, cantaloupes, cucumbers — sulfur is especially important for protein synthesis and improving fruit flavor. Sulphoammophos raises yields, fruit quality, and disease resistance.

Application specifics include:

• Application during primary tillage to improve soil nutrition.
• Top dressing during active growth stages.
• Combination with other fertilizers for comprehensive feeding.

This results in high-quality produce with better taste characteristics.
