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

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

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

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 .

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 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

Last week, we introduced many application scenarios of triacontanol as a plant growth promoter. You can review it here: https://www.kelewell.de/en/post/triacontanol-from-beeswax-to-biotechnology-the-science-of-natural-growth-stimulation Today, several plant growth promoters are commonly used on the market, such as triacontanol , brassinolide , sodium nitrophenolate , and DA-6 (diethyl aminoethyl hexanoate) . All of them help promote plant growth — but how exactly do they dif

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

Triacontanol  is a long-chain primary alcohol composed of thirty carbon atoms (a straight-chain saturated fatty alcohol). It is a natural long-chain plant growth regulator , widely found in the epicuticular waxes of plants  (plant waxes such as rice bran wax) and the exoskeleton waxes of insects  (insect waxes such as beeswax). Because it was first purified from beeswax, it is also called beeswax alcohol . At room temperature, triacontanol is a solid that is colorless or sli

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
