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

Plants determine whether an element is essential based on their own physiological and developmental needs. Elements in plant tissues are classified as essential  and non-essential . According to the required amount, essential nutrients are divided into macronutrients — nitrogen (N), phosphorus (P), and potassium (K); secondary nutrients — sulfur (S), calcium (Ca), and magnesium (Mg); and micronutrients — boron (B), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), molybdenum

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

As the most fundamental building blocks of living organisms, amino acids play an irreplaceable role in crop growth, physiological metabolism, and stress resistance. They are widely applied as functional nutrients in modern agriculture. Based on raw material sources, amino acids can be categorized into plant-based  and animal-based  types; based on production technology, they can be divided into hydrolyzed amino acids and enzymatically hydrolyzed amino acids . This article pr

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.

Introduction: Why has a “common chemical” moved into the heart of the new-energy industry? If you have ever worked in agriculture, manganese sulfate monohydrate is likely familiar—it is widely used to supplement manganese and support crop growth. Yet few would have imagined that, as new-energy vehicles dominate the roads and energy-storage stations stabilize power grids, this traditional chemical has quietly entered the core of the new-energy supply chain, becoming a critical

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

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 recent years, seaweed extract has rapidly become a popular input in green agriculture due to its natural origin, safety profile, and multiple physiological regulatory functions. Its application has expanded continuously—from large-scale grain production bases to fruit orchards, facility vegetable production, and even home gardening. However, in practical use, many growers notice a common issue: although products are all labeled “seaweed extract,” their performance varies d

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
