Agricultural Compound Fertilizer

AOLANSU agricultural compound fertilizers are meticulously developed and produced by Shandong AOLANSU Environmental Protection Technology Co., Ltd. We employ high-tower melt granulation and biochar-chelated slow-release technologies to integrate essential macronutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—with vital secondary and micronutrients such as Calcium (Ca), Magnesium (Mg), and Sulfur (S). With a total nutrient content of ≥45%, our fertilizers feature uniform granulation, excellent water solubility, and long-lasting efficacy (60–90 days).

As a manufacturer deeply committed to agricultural technology, we adhere to a philosophy of green, circular production; we carefully select raw materials and utilize a closed-loop manufacturing system to ensure that heavy metal and harmful impurity levels remain significantly below national standards. Our products are suitable for a wide variety of soil types and crops, thereby contributing to the sustainable development of agriculture.

Core Advantages

1. Precise Nutrition, Efficient Absorption

Our agricultural compound fertilizers feature a dual-layer nutrient structure—a fast-acting outer layer and a slow-release core. This design boosts the utilization rate of N, P, and K by over 20% compared to conventional fertilizers, thereby minimizing nutrient loss and reducing non-point source pollution.

2. Soil Improvement, Enhanced Resilience & Yield

Enriched with biochar and humic acid, our fertilizers promote the formation of soil aggregate structures, thereby enhancing water retention and nutrient-holding capacities. They also bolster crop resistance to drought, cold, and disease, resulting in yield increases of 8–15% for field crops and 10–20% for fruits and vegetables (while simultaneously improving quality).

3. Safety, Compliance, and Eco-Friendliness

We strictly adhere to the national standard GB/T 15063-2020 and hold ISO 9001 quality management system certification. Our production process generates zero wastewater discharge, ensuring full compliance with both Chinese and international environmental protection standards.

4. Customization and Comprehensive Support

We offer customized fertilizer formulations tailored to specific crop varieties, growth stages, and soil fertility levels. Our services include free soil testing, personalized fertilization plans, product samples for field trials, and continuous agronomic guidance throughout the entire crop cycle.

Product Parameters

Application Scenarios

1. Field Crops

Rice, Wheat, Corn, Soybeans. Apply as a basal fertilizer (40–50 kg/mu) or as a top dressing to promote tillering, strengthen stems, and ensure large, plump grain heads.

2. Fruit and Vegetable Crops

Cucumbers, tomatoes, watermelons, grapes, and citrus fruits. Apply a high-potassium formulation (20–30 kg/mu) as a top dressing during the fruit expansion stage to enhance sweetness, color, and post-harvest storability.

3. Cash Crops

Cotton, peanuts, tea, and medicinal herbs. Provide balanced fertilization throughout the entire growth cycle to improve fiber quality, oil extraction rates, and the content of active ingredients.

Real-World Application Case Studies

Case Study 1: Ratoon Rice Demonstration Field in Nanchang County, Jiangxi (2025)

Large-scale grower Chen Haomin applied AOLANSU 15-15-15 compound fertilizer (40 kg/mu as basal fertilizer + 20 kg/mu as top dressing). The demonstration field yielded a combined total of 2,744 jin per mu across two harvests—an increase of 855 jin compared to the control field (which used ordinary compound fertilizer)—resulting in an additional income of 755 yuan per mu. The rice panicles were plump with a low rate of empty or shriveled grains; furthermore, the grain quality improved, leading to a purchase price premium of 0.1 yuan per jin.

Case Study 2: Cucumber Greenhouse in Shouguang, Shandong (2025)

Grower Ms. Wang applied AOLANSU's high-potassium 18-8-18 formulation as a top dressing (15 kg/mu per application, at 10-day intervals). The cucumbers grew straight and green with uniform lengths, and the rate of malformed fruit was less than 3%. Compared to crops treated with ordinary compound fertilizer, the harvest reached the market 7 days earlier, yielding an additional 1,200 kg per mu and generating an extra income of 3,600 yuan per mu.

Case Study 3: Peanut Field in Tieling, Liaoning (2025)

Grower Zhao Lei applied AOLANSU 15-15-15 sulfur-based compound fertilizer as a basal fertilizer (50 kg/mu). The peanut pods were plump with an empty-pod rate of less than 3%. The yield of dried peanuts reached 464.52 kg per mu—a 16.18% increase compared to the control field—while the weight per 100 pods increased by 12%, and the purchase price was 0.2 yuan higher per jin.

FAQ

Q1: Is AOLANSU agricultural compound fertilizer suitable for chloride-sensitive crops?

A: We offer two formulations: a sulfur-based type (containing ≤3% chloride ions) and a chloride-based type. For chloride-sensitive crops—such as watermelons, grapes, potatoes, and tobacco—we recommend the sulfur-based formulation. For chloride-tolerant crops—such as rice, wheat, and corn—the chloride-based formulation is a cost-effective choice.

Q2: Compared to ordinary compound fertilizers, how do AOLANSU products differ in terms of nutrient release duration and utilization efficiency?

A: Our fertilizers feature a nutrient release duration of 60–90 days (compared to the standard 40–60 days). Furthermore, the utilization rate for nitrogen, phosphorus, and potassium reaches 35%–40% (compared to the standard 20%–25%). This allows for a 20%–30% reduction in application dosage to achieve the same yield, thereby lowering costs and reducing environmental impact.

Q3: How should the fertilizer be stored and applied to prevent fertilizer burn and maximize effectiveness?

A: ① Storage: Store in a cool, dry place; protect from moisture and direct sunlight; and keep away from seeds and young seedlings. ② Application: Apply as a base fertilizer by deep placement (10–15 cm) to avoid direct contact with plant roots (maintain a minimum distance of 10 cm). For top-dressing, apply in small doses multiple times, and ensure irrigation is provided during dry seasons. ③ Contraindications: Do not mix with strongly alkaline pesticides, and avoid excessive application.
