As modern agriculture places increasing emphasis on crop health and quality, nutrient imbalance has become a central concern in crop management. Among various nutritional disorders, iron chlorosis is one of the most widespread and impactful problems affecting a wide range of crops, directly constraining growth, yield, and quality. Among the available iron supplementation solutions, EDDHA-Fe, as a highly stable chelated iron fertilizer, has gradually emerged as a preferred opt

Among the 17 essential nutrients required by plants, magnesium occupies a uniquely critical position . It is not only the only metallic element in the chlorophyll molecule , but also a key activator of plant energy metabolism . For modern agriculture—especially the cultivation of high-value cash crops—understanding the fundamental role of magnesium and mastering its efficient supplementation strategies is indispensable for achieving both high yield and premium quality. The Fi

From January to November 2025, China’s fertilizer imports and exports showed a clear pattern of rising export volumes and prices alongside a slight decline in imports. Toward year-end (mid-December), the market centered on three main themes: policy-driven price stability and supply assurance for phosphate fertilizers, supply–demand tug-of-war in the potash market, and policy regulation of upstream raw materials. Phosphate rock, sulfur, and sulfuric acid exhibited divergent tr

Many tomato growers have experienced this common challenge: abundant flowering during the blooming stage, yet after a cold snap or strong wind, flowers drop heavily, resulting in poor fruit set. Even when fruits do set, misshapen or undersized fruits are frequent, significantly reducing yield and market quality. In fact, the flowering stage is the critical window that determines final tomato yield. During this period, plant demand for phosphorus (P) and potassium (K) rises sh

In agricultural production, phosphate fertilizers are essential to crop growth and development. What many may not realize is that the starting point of most common phosphate fertilizers is often a pale yellow, brittle crystal or powder — sulfur . With a global annual output of approximately 70 million tons , around 80% of sulfur supply comes as a byproduct of petroleum refining and natural gas processing , making it deeply intertwined with the global energy landscape. Sulfur

I. The Plant’s “Small-Molecule Expressway”: Why Are Amino Acid Fertilizers Becoming a New Trend? Unlike traditional fertilizers that must be converted by soil microorganisms before plants can absorb them, amino acid fertilizers exist in small-molecule form and can be directly absorbed and utilized by plant cells. This enables instant, precise nutrient delivery, perfectly suited to modern efficient and environmentally friendly cultivation practices. In simple terms, amino acid

China’s Annual Contract Anchors Global Pricing While Supply–Demand Dynamics Shape the Market In November 2025, China finalized its 2026 annual potash import contract—an event that quickly became the central anchor for global potash pricing. The agreement not only halted the price slide in several emerging markets but also ignited China’s winter fertilizer stocking season. At the same time, rising sulfur and sulfuric acid prices pushed production costs sharply higher, placing

In modern precision viticulture, Monopotassium Phosphate (0-52-34) has evolved from a supplementary foliar fertilizer into a central “physiological regulator”  applied across the entire grape growth cycle. Its value extends far beyond supplying phosphorus and potassium. What truly elevates MKP is its unique scientific profile—high solubility, pure nutrient forms, and synergistic absorption—which allows it to precisely activate photosynthesis, stress resistance, and quality f

By the end of November 2025, China’s fertilizer market displayed clear structural characteristics: While the potash sector benefited from the newly signed annual import contract that set a cost floor, downstream demand remained weak, limiting actual transactions and keeping the market in a state of fragile stability. Conversely, upstream raw materials such as phosphate rock, sulfur, and sulfuric acid showed structural upward trends driven by tight supply or cost-push effects.

Every spring-sowing season, many farmers ask our agronomy team: “We already applied autumn fertilizer. Now that we’re sowing in spring, should the first irrigation also include fertilizer?” Once you clearly understand the timing and purpose of base fertilizer, seed fertilizer, seedling fertilizer, and topdressing , the answer becomes obvious. I. Base Fertilizer: The “Nutrient Foundation” for the Entire Growth Cycle 1. Definition Base fertilizer — also called pre-plant fertili

I. Overview of China’s Fertilizer Import and Export (January–October 2025) (1) Exports: Significant Growth in Both Volume and Value From January to October 2025, China exported a total of 38.42 million tons of bulk fertilizers, representing a year-on-year increase of 48.3%. The total export value reached USD 11.55 billion, up 64.56% from the previous year. In October alone, exports remained exceptionally strong: 5.057 million tons, up 71.1% year-on-year, with an export value

In the field of plant growth regulation, gibberellins (GAs) form a vast “family” of natural compounds — with more than 130 distinct gibberellins identified to date. Acting as the plant’s internal “growth commanders,” these substances coordinate essential physiological processes such as seed germination, stem elongation, flowering, and fruit development. Interestingly, the discovery of this family traces back to a puzzling rice disease that once troubled farmers, leading scien

In the pursuit of efficient and high-quality agriculture, scientific fertilization is not only the core to improving crop yields but also the key to enhancing produce quality and protecting soil ecology. Calcium magnesium nitrate, a compound medium-element fertilizer with both “quick-acting” and “multi-functional” characteristics, is becoming increasingly popular as it provides three essential nutrients—nitrogen (N), calcium (Ca), and magnesium (Mg)—in one product. This advan

I. Potash Fertilizer Market: Intensified Supply–Demand Game and Noticeable Regional/Product Divergence (1) Potassium Chloride Market: Mixed Trends and Narrowing Regional Price Gaps China’s potassium chloride market has shown a complex, fluctuating pattern with clear regional divergence in prices.Imported potassium chloride inventories are characterized by a “more in the north, less in the south” distribution. Local circulation is loose in some areas, but the overall supply–de

In the “nutrient supply system” of agricultural production, potash fertilizers play an irreplaceable role as “energy regulators,” directly influencing crop growth vigor, stress resistance, and final yield. Among the many potash fertilizer types, potassium chloride (KCl) and potassium sulfate (K₂SO₄) stand out as the two dominant forms. The two are closely related yet differ in their characteristics and application scenarios. This article explores their intrinsic connection, a

I. International Market Updates (1) Indonesia’s B50 Policy Marks a “Historic Turning Point” for Potash Demand Indonesia’s Minister of Energy and Mineral Resources, Arifin Tasrif, recently announced that biodiesel containing 50% palm oil-based biofuel (B50) has completed laboratory testing and is expected to be fully implemented in the second half of 2026, aiming to achieve zero diesel imports . This policy will reshape the palm oil industrial chain and trigger an explosive in

In agricultural production, the healthy growth of crops depends on the “nourishment” of various micronutrients, among which iron plays an indispensable role.When crops face an “iron deficiency crisis,” ferrous sulfate monohydrate often steps in as the key solution. As a commonly used iron supplement fertilizer in agriculture, it safeguards crop growth and improves yields with its high efficiency and excellent bioavailability.This article focuses on the agricultural applicatio

I. Import and Export Overview (January–September / September 2025) According to preliminary statistics from China Customs, in the first three quarters of 2025, China’s fertilizer trade showed a trend of “rising exports in both volume and value” and “declining imports in both volume and value.” Export growth in September alone was particularly significant. Detailed data are shown in the table below: Indicator Period Quantity (10,000 tons) Value (USD billion) YoY Change Other K
