Winter brings a challenge for every grower — low soil temperature slows down root growth, weakens nutrient uptake, and increases the risk of root rot or frost damage. Effective winter root management for crops focuses on both environmental adaptation and precise cultivation practices. Below are four field-proven strategies to help roots stay active, grow deeper, …

In the agricultural world, humic acid is known as the “all-round helper” — it improves soil structure, boosts root growth, enhances stress resistance, and increases fertilizer efficiency. But few people truly understand why it works so well. In fact, the power of humic acid lies in its ability to coordinate the soil–plant–microbe system. Let’s break …

In modern agriculture, organic nitrogen from crop residues, manure, or compost plays a key role in soil fertility—but most of it exists in complex, large molecular forms that plants cannot directly absorb. Here comes Bacillus subtilis, the “pioneer microorganism” that initiates the transformation of organic nitrogen into plant-available, fast-acting nitrogen. 1. The Core Function of …

In the field of modern plant nutrition, sugar alcohols (polyols) such as mannitol, sorbitol, and xylitol have become valuable natural chelating agents. They not only stabilize essential nutrients but also improve their transport and absorption within the plant system. As a result, sugar alcohols are increasingly used in high-efficiency fertilizers designed for sustainable agriculture. 1. …

Introduction: Amino Acids—Nutrients or Growth Regulators? Amino acids are widely recognized as essential nutrients that promote plant growth. However, recent agronomic research has revealed another fascinating role—growth regulation.When used at high concentrations, certain amino acids can control excessive vegetative growth, redirecting nutrients toward fruit development and improving both yield and quality. For growers who are …

In the era of green and sustainable agriculture, natural and safe bio-based agricultural inputs are increasingly essential. Among them, chitosan oligosaccharide (COS)—a bioactive compound derived from the degradation of chitin—has attracted wide attention due to its biodegradability, zero residue, and multifunctional agricultural benefits. Also known in agriculture as oligoglucosamine or amino-oligosaccharide, this innovative material offers …

Calcium (Ca) is the “rebar” of cell walls and fruit skins, but it cannot be redistributed through the phloem. It mainly moves with the transpiration stream to young shoots and fruits. This means that water and environmental conditions decide whether calcium reaches its target—choosing the right calcium source is only the second step. 1. What …

Ethylenediaminetetraacetic acid (EDTA) is one of the most widely used chelating agents in industrial production and agricultural applications. Owing to its strong chelating ability, EDTA can effectively “bind and lock” metal ions, thereby modifying their chemical properties and improving their availability or mobility. Structurally, EDTA contains two amino groups and four carboxyl groups, each carrying …
