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

From Chemical Nature to Global Soil Adaptation — Understanding the True Role and Potential of Potassium Carbonate in Agriculture

In our March article , we explored how boric acid  enhances glass performance — acting as a flux, improving tensile strength, and boosting thermal stability and refractive index. You can revisit that post here:👉 Boric Acid and Its Applications in the Glass Industry Today, we dive deeper — uncovering how borates play distinct yet critical roles in different glass types , from insulation fiber glass to borosilicate and optical glass.

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

Ammonium sulfate is an inorganic compound with the chemical formula  (NH₄)₂SO₄ . It is a product of the reaction between sulfuric acid and ammonia, containing 20–21% nitrogen and 24% sulfur. The pure form appears as colorless, transparent crystals in the orthorhombic system. Its aqueous solution is acidic, and it is insoluble in alcohol, acetone, and ammonia water. It has hygroscopic properties, which cause it to solidify into lumps when it absorbs moisture. It is mainly used
