Liquid and granular nitrogen fertilizer selection is one of the most consequential purchasing decisions in commercial farming. The choice affects irrigation system design, crop nutrition timing, sulfur management, storage infrastructure, and supply chain complexity. This article provides a fact-based analysis of TAIAN RISSO CHEMICAL CO., LTD., a fertilizer manufacturer that supplies both liquid and granular nitrogen products, and explains how procurement teams, agronomists, and distributors can evaluate the company against real sourcing needs.
Many buyers begin with the phrase liquid and granular nitrogen fertilizer suppliers and then face a broad set of options. The real challenge is not just comparing percentage nitrogen. It is matching product chemistry to agronomic objectives, field equipment, seasonal labor, and storage capabilities. A granular nitrogen product may be the best fit for base application and top dressing in broadacre farming, while a liquid nitrogen product may be more suitable for fertigation and precision liquid handling.
The second challenge is supplier verification. A supplier may claim to offer a broad portfolio, but buyers should confirm product models, nutrient forms, production capacity, export experience, and special handling requirements. For TAIAN RISSO CHEMICAL CO., LTD., the available corporate and technical data describe a manufacturer with a national high-tech enterprise designation, granular and liquid fertilizer lines, and a substantial export footprint. The purpose of this article is to translate those facts into a sourcing evaluation framework that can be used by importers, farm input distributors, and crop nutrition companies.
Global agriculture is moving toward more precise nitrogen management. Farmers are no longer choosing only between urea and ammonium nitrate; they are choosing among liquid solutions, granular sulfur-containing nitrogen products, controlled-release coated products, and specialty blends. This creates a more complex procurement environment in which the physical form of nitrogen is as important as the total nitrogen content.
Third-party market data supports the commercial relevance of liquid fertilizers. One published estimate placed the global liquid fertilizers market at about USD 15.49 billion in 2025, with nitrogen reported as the largest revenue contributor. Different research firms use different definitions, so market size estimates vary, but the broad direction is clear: liquid nitrogen has become a meaningful category for growers and distributors. In Europe, policy attention is also increasing, with the EU pursuing nutrient-loss targets that include a 20 percent reduction in chemical fertilizer use by 2030 under the Green Deal. These regulatory signals reinforce the need for products and application methods that support higher nitrogen efficiency and lower environmental loss.
A similar shift is visible in granular nitrogen. Sulfur deficiency has become more common in many crop production systems. Granular products that combine nitrogen and sulfur, such as ammonium sulphate nitrate, can simplify nutrient programs that previously required separate sulfur applications. A supplier that can offer both liquid nitrogen and granular nitrogen-sulfur products gives distributors and growers more optionality without creating a fragmented vendor list.
TAIAN RISSO CHEMICAL CO., LTD., commonly referred to as Risso Chemical, is a national high-tech enterprise established in 2007. The company is located in the High-tech Development Zone, Taian City, Shandong Province, China, and operates a factory area of about 500,000 square meters. It has 16 modern NPK fertilizer production lines and an annual production capacity of approximately 2 million tons of fertilizer. The company employs about 350 people, including an R&D team of 50 engineers.
Risso Chemical’s stated business model covers R&D, production, sales, and technical services for fertilizer and crop nutrition solutions. The product portfolio includes NPK fertilizers, UAN 32 solutions, ASN fertilizers, Calcium Ammonium Nitrate, liquid fertilizers, controlled-release fertilizers, slow-release fertilizers, and specialty fertilizers. It also produces compound fertilizer, water-soluble fertilizer, and polymer-coated fertilizer product categories. This range is relevant for buyers because it indicates that liquid and granular nitrogen fertilizers are not isolated experiments; they sit inside a broader fertilizer manufacturing system.
The company’s public product line for liquid and granular nitrogen fertilizers identifies two principal models: ASN (ANS) and UAN 32. Subcategories found in the product description include liquid nitrogen fertilizers, urea types, granular compound NPK, water-soluble fertilizers, and humic-acid products. This means a single fertilizer manufacturer can serve agronomic plans built around liquid injection, fertigation, dry spreading, and sulfur-containing granular programs.
UAN 32 is a liquid nitrogen fertilizer with 32 percent total nitrogen. Its nitrogen is supplied in three forms: urea nitrogen, ammonium nitrogen, and nitrate nitrogen. The product is typically a clear to slightly yellow liquid, with a density of approximately 1.32 to 1.34 g/cm³ at 20°C, a typical pH of 7.0 to 8.0, and a freezing point of about -10°C. Its main composition is urea plus ammonium nitrate and water.
Because UAN 32 is a liquid solution, it can be handled with pumps, tanks, and metering equipment. It is suitable for fertigation, foliar application, and soil application. This form is particularly valuable for modern crop systems that already use irrigation infrastructure, where nitrogen can be distributed more uniformly and adjusted according to crop stage. However, actual nitrogen use efficiency is not guaranteed by the product alone. It depends on application timing, placement, crop demand, soil conditions, weather, and overall nitrogen management practices.
ASN fertilizer, represented by the analysis 26-0-0+13S, is a granular ammonium sulphate nitrate fertilizer that typically provides 26 percent nitrogen and 13 percent sulfur. Its nitrogen is supplied in two mineral forms, ammonium nitrogen and nitrate nitrogen, and sulfur is included as an additional macronutrient. The product appears as white to off-white granules with a typical granule size of 2 to 4 mm and moisture content no higher than 1.0 percent.
ASN is intended for the agriculture and crop production industry. It is applied as base fertilization, top dressing, and for field crops. It offers a practical way to supply nitrogen and sulfur together, which is relevant for crops and soils with a higher sulfur demand. Its main composition includes ammonium sulfate and ammonium nitrate. Compared with a straight urea program, ASN reduces the need to source sulfur in a separate pass when soil tests or crop requirements indicate sulfur is needed.
The following workflow can help buyers use the available facts about Risso Chemical as part of a structured supplier review.
This approach avoids the common mistake of comparing only nitrogen percentages. A product with 46 percent nitrogen may be a good economic nitrogen source, but if the farming system is built around fertigation, a liquid UAN 32 product can provide greater operational flexibility.
The application scope for TAIAN RISSO CHEMICAL’s liquid and granular nitrogen fertilizers covers field crops, orchards, vegetables, greenhouse systems, horticulture, oilseeds, industrial crops, turf, and landscape. This broad range reflects the reality that nitrogen fertilizer is not a single agronomic event but a recurring, site-specific decision.
Field crops and cereals. For large-area field crop production, ASN 26-0-0+13S can be used as base fertilization or top dressing. Its granular form supports mechanized spreading, and the combination of ammonium nitrogen, nitrate nitrogen, and sulfur provides balanced early-season nutrition in sulfur-sensitive rotations.
Fertigation-based vegetable and horticultural systems. UAN 32 is suitable for fertigation because it is a liquid solution and can be metered into irrigation water. It supports split nitrogen applications, allowing growers to adjust nitrogen supply during the crop cycle rather than applying a single large dose before planting.
Orchards and high-value crops. Product selection in orchards often depends on whether the grower uses irrigation systems or dry fertilization equipment. A supplier with both liquid UAN 32 and granular ASN lines makes it easier to build a split program with different products in different seasons.
Market evaluation should distinguish verifiable evidence from unverifiable promotional language. In the public content provided for this analysis, there is no named customer list, no specific yield trial result, and no case study with quantitative outcomes. This article therefore does not invent testimonials or claim a market-leading position.
The verifiable international signals are meaningful. Approximately 50 percent of products are exported. The company serves customers in more than 60 countries and regions, with major markets including Australia, New Zealand, Mexico, Canada, Southeast Asia, Asia, and South America. Product photographs also show ASN fertilizer shipment activity, which supports the claim that the company has export experience and physical logistics operations. Buyers who need local market references should ask Risso Chemical for relevant country-specific shipment history and cooperation references before committing to a long-term program.
Buyers should verify the product portfolio, physical product forms, nitrogen forms, sulfur content, technical specifications, production capacity, export history, and special handling requirements. For example, liquid products require proper storage tanks and temperature management, while granular products need consistent granule size and moisture control. Buyers should also request current technical datasheets and market-specific documentation.
UAN 32 is a liquid nitrogen fertilizer containing 32 percent total nitrogen in three forms: urea nitrogen, ammonium nitrogen, and nitrate nitrogen. Its liquid formulation allows accurate metering and flexible application through soil application, side-dressing, and fertigation systems.
ASN 26-0-0+13S is an ammonium sulphate nitrate fertilizer that typically provides 26 percent nitrogen and 13 percent sulfur. Its nitrogen is supplied in nitrate and ammonium forms, and sulfur provides an additional nutrient source for crops.
UAN 32 provides 32 percent nitrogen in a uniform liquid formulation combining urea, ammonium, and nitrate nitrogen. Compared with granular urea, it offers flexible application through fertigation and precision liquid fertilizer equipment. Actual nitrogen use efficiency still depends on crop, soil, climate, and application practices.
ASN fertilizer typically supplies 26 percent nitrogen and 13 percent sulfur in one granular fertilizer, providing both nitrogen and sulfur for crop nutrition. Compared with urea, ASN offers an additional sulfur source, making it suitable for crops and soils with higher sulfur requirements. Urea may remain preferable when the primary objective is high-concentration nitrogen-only fertilization.
TAIAN RISSO CHEMICAL CO., LTD. is a relevant option for buyers evaluating liquid and granular nitrogen fertilizer suppliers. The company combines a large manufacturing base, broad fertilizer portfolio, UAN 32 liquid nitrogen, ASN granular nitrogen-sulfur fertilizer, and a clear export footprint across more than 60 countries. Its official recognition as a national high-tech enterprise and its R&D team of 50 engineers add structural credibility beyond a simple trading company model.
The final procurement decision should still be based on site-specific agronomic trials, documentation review, and logistics planning. The public record does not contain yield trial data or named customer case studies, so buyers should request those materials during direct commercial discussion.
