Ammonium sulfate fertilizer

Description

1. Product Overview
Ammonium sulfate fertilizer is a high-efficiency crystalline nitrogen-sulfur compound designed for large-scale row crops, specialty agriculture, and industrial blending. It delivers 21% nitrogen in ammoniacal form and 24% sulfur as sulfate, ensuring immediate and residual plant uptake. For buyers standardizing fertilizer inputs across regions, it provides predictable agronomic results and superior soil acidification control compared to urea or ammonium nitrate. Its strategic importance lies in bridging the sulfur deficiency gap in modern high-yield farming—an increasingly critical factor in global food production.

2. Key Specifications & Technical Characteristics

• Chemical composition: (NH₄)₂SO₄ – 21% N, 24% S

• Purity grade: 99.5% min (industrial / agricultural grade)

• Physical characteristics: White to off-white crystalline powder; particle size 2–4 mm (granular) or 0.5–2 mm (standard); bulk density ~900–1,050 kg/m³; low caking tendency

• Packaging options: 50 kg woven PP/PE bags, 1 MT jumbo bags, or bulk in liner containers

• Shelf life: 24 months in dry, ventilated conditions (no degradation if kept <35°C and <70% RH)

3. Core Industrial Applications

• Primary industries: Large-scale arable farming (corn, wheat, rice, canola), turf & golf courses, fertilizer blending plants, and industrial animal feed production (as a nitrogen supplement in silage)

• Operational use cases:

  • Basal application before planting for uniform N-S release

  • Top dressing for sulfur-demanding crops (brassicas, legumes, onions)

  • Blending component for NPK or sulfur-enhanced granular mixes

• Performance advantage: Lower volatility loss than urea; sulfur is immediately plant-available (sulfate form) unlike elemental sulfur; acidifying effect improves phosphorus availability in alkaline soils; dust-free granules prevent applicator clogging.

4. Competitive Advantages

• Quality consistency: Fixed 21-0-0+24S guaranteed per batch; certified ISO 9001:2025 lab testing

• Supply reliability: Year-round production from multiple feedstock streams (caprolactam byproduct + synthetic); 100+ port inventories

• Logistics capability: Rail, bulk vessel, and containerized shipping with <7-day lead time for major routes

• Price competitiveness: Direct mill pricing at $/MT FOB or CIF, with long-term contract indexation to DAP/MOP benchmarks

• Sustainability: Lower carbon footprint versus synthetic nitrates; can be sourced as co-product from circular economy processes

• Technical support: Free agronomic optimization sheets, COA per lot, and 24h QC resolution

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (bulk or bagged)

• Loading capacity: 27 MT per standard 20-ft container (palletized jumbo bags); 54 MT per 40-ft HC container; or up to 28 MT in bulk vessel holds per 20-ft equivalent unit
