Humic acid and fulvic acid are derived from the same source — leonardite or decomposed organic matter — but they behave very differently in soil and plant nutrition. This guide compares their properties and helps you choose the right product for your crops. What Are Humic Substances? Humic substances are the stable end-products of microbial …
When sourcing chelated micronutrients for agriculture, two chelating agents dominate the market: EDTA (Ethylenediaminetetraacetic acid) and DTPA (Diethylenetriaminepentaacetic acid). Both effectively bind metal micronutrients — iron, zinc, copper, manganese, and others — into stable, plant-available forms. But they differ significantly in pH stability, cost, and best-use scenarios. This guide helps fertilizer manufacturers, agronomists, and procurement …

As the global electric vehicle (EV) market accelerates, demand for battery-grade lithium chemicals has surged. Two products sit at the center of this demand: lithium carbonate (Li₂CO₃) and lithium hydroxide monohydrate (LiOH·H₂O). While both are essential lithium precursors for battery cathode manufacturing, they serve different applications and have distinct supply chain implications. The Role of …

Micronutrient deficiencies are responsible for significant crop yield losses worldwide. While they are needed in small quantities, elements like zinc, copper, manganese, iron, and calcium are essential for plant enzyme function, photosynthesis, and disease resistance. EDTA chelated micronutrients are the most effective way to deliver these elements to crops in a bioavailable form. Why Chelation …

Iron deficiency (chlorosis) is one of the most common micronutrient problems in agriculture, especially in alkaline and calcareous soils. Two chelated iron products — EDDHA Fe and EDTA Fe — are widely used to correct this deficiency, but they perform very differently depending on soil pH. Understanding the difference helps you choose the right product …
