Description

Slow Release Compound Fertilizer, produced by Shandong Aolansu Environmental Protection Technology Co., Ltd. is a high-performance inorganic compound fertilizer integrating nitrogen (N), phosphorus (P₂O₅), potassium (K₂O) and essential medium and trace elements, widely used in field crops, vegetables, fruit trees and economic crops. It is manufactured in a standardized China factory of Aolansu, adopting high-quality raw materials and advanced resin coating slow-release technology, strictly complying with the national standard GB/T 23348-2009 and international ISO 18644:2016 standard, with no harmful additives, ensuring safety, environmental protection and reliability in long-term agricultural application. The product is off-white to light gray uniform granules, odorless, non-toxic, with good fluidity and no caking, easy to store, transport and apply.
     


     The core advantage of this Slow Release Compound Fertilizer lies in its scientific slow-release technology and balanced nutrient ratio. Different from traditional quick-release fertilizers that easily cause nutrient loss and fertilizer burn, Aolansu’s slow-release compound fertilizer uses high-quality resin coating technology to form a uniform and breathable protective film on the surface of fertilizer particles. This film can slowly decompose with the change of soil temperature, moisture and microbial activity, controlling the release rate of nutrients to perfectly match the nutrient demand of crops in different growth stages—slow release in the seedling stage, moderate release in the tillering and flowering stage, and sufficient release in the fruiting and mature stage. This not only avoids nutrient waste caused by excessive release, but also prevents nutrient deficiency caused by insufficient release, greatly improving nutrient utilization rate to more than 45%, which is 10-15 percentage points higher than traditional compound fertilizers.



     The China factory of Aolansu adopts strict production and quality control processes, from raw material selection to product delivery, implementing full-process supervision. Raw materials are strictly screened and tested to ensure no heavy metals, harmful impurities or excessive chloride ions, meeting international agricultural fertilizer standards and the requirements of GB/T 23348-2009 and ISO 18644:2016. The production process adopts advanced mixing, granulation and coating integration technology, which not only ensures the uniform distribution of nutrients in each particle, but also makes the coating thickness uniform, ensuring stable slow-release effect of each batch of products. Every batch of products is tested by professional laboratories to detect indicators such as total nutrient content, slow-release rate, moisture and particle size, ensuring that all indicators meet the standard and the product quality is stable and reliable.
     


     This Slow Release Compound Fertilizer is suitable for almost all field crops, vegetables, fruit trees and economic crops, including rice, wheat, corn, soybeans, cotton, tomatoes, peppers, apples, pears, grapes, tea plants and potatoes. It is applicable to various soil types such as acidic, alkaline and neutral soils, and can adjust soil pH, improve soil structure and enhance soil fertility with long-term use. Compared with traditional fertilizers that require multiple topdressings, this product can be applied once as basal fertilizer, reducing the number of fertilizations by 2-3 times, saving labor costs and avoiding crop damage caused by improper topdressing. It can be applied by broadcasting, furrow application, hole application or drip irrigation, flexible and convenient to meet different planting needs and planting scales.
     


     As an experienced China supplier and manufacturer, Aolansu fully understands the actual needs of global agricultural purchasers, focusing on product quality, cost control and supply stability. We support small-batch trial orders (minimum 1 ton), allowing purchasers to test the product effect in local soil and crops, reducing procurement risks. For long-term bulk purchasers, we provide preferential factory-direct prices, eliminate intermediate links, and effectively reduce the comprehensive procurement cost of purchasers.
     


     In terms of packaging and delivery, the factory of Aolansu uses international standard agricultural packaging: 25kg PE-lined plastic woven bags, 50kg galvanized iron drums or 1000kg ton bags, which are moisture-proof, wear-resistant and corrosion-resistant, ensuring that the product is not damp, caked or damaged during long-distance transportation and storage. We can also provide customized packaging and labeling according to the specific needs of purchasers. The factory maintains sufficient inventory throughout the year, and has a professional logistics team with rich experience in international agricultural product transportation, which can smoothly deliver goods to Southeast Asia, Africa, South America, Europe and other major agricultural regions, ensuring timely delivery and smooth customs clearance.
     


     The product has no irritating odor, is easy to store and transport, and can be stored for a long time under cool, dry and ventilated conditions without deterioration. It is compatible with most other agricultural fertilizers, such as organic fertilizer and microbial fertilizer, which can be mixed and applied to achieve complementary nutrients and further improve fertilization effect. Regular use of this Slow Release Compound Fertilizer can not only supplement crop nutrients in a balanced way, improve crop yield and quality, but also reduce nutrient loss, protect the ecological environment, and achieve the goal of energy saving, emission reduction and sustainable agricultural development, which is in line with the global concept of responsible consumption and production.
   


     As a trusted China supplier, Aolansu focuses on providing practical and efficient fertilizer solutions for global agricultural purchasers, without redundant publicity, only reliable products and thoughtful services. Our Slow Release Compound Fertilizer has the characteristics of stable quality, scientific slow-release effect, wide applicability and competitive price, which can effectively help purchasers reduce planting costs, save labor and improve economic benefits.

FAQ

English:
     Q1: What is the difference between Slow Release Compound Fertilizer and traditional quick-release compound fertilizer?
     
A1: The biggest difference lies in the nutrient release mode. Traditional quick-release compound fertilizer releases nutrients rapidly, which easily causes nutrient loss through leaching and volatilization, and may lead to fertilizer burn. Our slow-release compound fertilizer adopts resin coating technology to control nutrient release rate, which matches the crop growth cycle, with higher nutrient utilization rate (more than 45%), fewer fertilization times and labor-saving advantages. It also avoids environmental pollution caused by nutrient loss.
     


     Q2: Can this product be used for both field crops and fruit trees? What is the recommended dosage?
     
A2: Yes, it is suitable for almost all field crops, fruit trees, vegetables and economic crops. The recommended dosage varies according to crop types and soil fertility: 30-40kg per mu for grain crops such as rice and wheat (as basal fertilizer); 40-60kg per mu for fruit trees and vegetables (as basal fertilizer). It can be adjusted appropriately according to actual planting needs.


     Q3: Can the nutrient release period of the product be customized according to our needs?
     
A3: Yes. As a professional China manufacturer, Aolansu can customize the nutrient release period (3-12 months) according to the specific growth cycle of your local crops and soil conditions, ensuring that the nutrient supply perfectly matches the crop growth needs and maximizing the fertilization effect.
