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.

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

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. 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

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
