I. Why Is Magnesium Essential in Aquaculture? In aquaculture practice, many production problems do not originate directly from diseases, but from more fundamental and often overlooked factors—imbalances in waterborne minerals. Issues such as failed molting in crustaceans, increased mortality after stress events, unstable water quality, and disrupted algal communities are frequently linked to deficiencies or improper ratios of basic ions such as magnesium in the culture water.

From December 26, 2025 to January 9, 2026, China’s domestic fertilizer market operated around the core theme of “price stability and supply assurance for phosphate fertilizers.” On the raw material side, clear divergence was observed: phosphate rock remained largely stable, sulfur fluctuated at high levels, while sulfuric acid and synthetic ammonia stayed broadly stable. The potash market continued to operate under a tight supply–demand balance, with prices holding firm at el

In agricultural production, potassium nitrate stands out as a key fertilizer for fruit enlargement, quality improvement, stress resistance, and yield enhancement due to its unique dual supply of nitrogen and potassium. It provides crops with readily available nitrate nitrogen, promoting photosynthate formation and nutrient transport, while also supplying potassium, which enhances cellular structural stability and improves overall resistance to lodging, environmental stress, a

Recently, the international fertilizer market has shown clear characteristics of concentrated demand release supported by government subsidy policies. Countries including India, Indonesia, and Nepal have actively advanced fertilizer tenders and procurement programs, while Pakistan recorded record-high fertilizer sales. Against this backdrop, China’s potash market concluded 2025 at elevated but stable levels, and entered 2026 with continued firmness. Potassium chloride prices

By late December, China’s fertilizer market has exhibited clear structural characteristics. On the raw material side, sulfur shows a pattern of domestic price pullback alongside high-level volatility in imported material, while phosphate rock, sulfuric acid, and synthetic ammonia remain broadly stable. The phosphate fertilizer market continues to implement policy-driven supply assurance and price stabilization, with prices remaining steady despite rising cost pressure. The po

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

In early December 2025, China’s fertilizer market entered a critical phase characterized by across-the-board cost increases and a continued tight supply–demand balance. Rising prices of raw materials such as sulfur and sulfuric acid have pushed up costs for phosphate fertilizers and potassium sulfate. Meanwhile, the potash market remains firm at high levels, supported by concentrated supply and rigid winter stocking demand.In the international market, a pattern of strong dem

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

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.

In the fourth quarter of 2025, the global fertilizer industry is marked by distinct trends of “strategic upgrading, rising demand, and active trade.” The United States has, for the first time, included phosphate rock and potash in its Critical Minerals List, underscoring the national-security importance of fertilizer resources. Nutrien, the world’s largest fertilizer producer, forecasts continued growth in global potash demand in 2026, prompting adjustments in industry planni

In November 2025, China’s fertilizer market exhibited a clear trend driven by raw materials. Supported by increasingly tight supply, the potash fertilizer market continued its upward movement, forming a “high in the north, low in the south” price pattern. Meanwhile, sharp increases in the prices of sulfur, sulfuric acid, and other raw materials pushed phosphate compound fertilizer production costs sharply higher, triggering an upward adjustment in industry guideline prices. H

Zinc is an indispensable “star micronutrient” in plant growth and development. It participates in chlorophyll synthesis, enzyme activation, nutrient metabolism and other key physiological processes, directly influencing crop yield and quality. However, traditional zinc fertilizers are easily fixed in soil, resulting in low availability. EDTA-ZnNa₂ (Ethylenediaminetetraacetic Acid Zinc Disodium), with its stable chelated structure, provides a more efficient and reliable soluti

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
