The differences among bio-fermented humic acid, chemically synthesized humic acid, and oxidatively regenerated humic acid.

From the perspective of humic acid types, the main categories are bio‑fermented humic acid, chemically synthesized humic acid, and oxidatively regenerated humic acid. Their raw material sources are extremely diverse, including crop straw, wood chips, sugar‑production residues, bagasse, brewing waste liquids, paper‑making waste liquids, animal manure, and a wide range of other readily available agricultural by‑products and renewable industrial waste materials.

Controlled-release fertilizer, slow-release fertilizer, and compound fertilizer—mastering the proper application methods saves time, effort, and worry.

How do these two types of slow-release and controlled-release fertilizers differ from the compound fertilizers we commonly use? Aren’t they all just fertilizers? Indeed, most of them are formulations that supply nitrogen, phosphorus, and potassium. However, they still vary in terms of application methods, suitability for potted flowers, and the duration of their effectiveness.

What exactly does controlled-release fertilizer control? Why choose controlled-release fertilizer?

Controlled-release fertilizers represent an advanced form of slow-release fertilizers. They primarily regulate nutrient release through a coating, achieving safety, long-lasting efficacy, and high efficiency. As a key direction in modern fertilizer development, they are well-suited for mechanized production, particularly for meeting the requirements of simultaneous seed‑fertilizer application.

Science and Technology Department of the Ministry of Agriculture: “8 Questions and 8 Answers” on Spring Wheat Management—Early Application of Humic Acid Water-Soluble Fertilizer

Recently, the Science and Education Department of the Ministry of Agriculture and Rural Affairs, in response to key spring‑management issues raised by farmers on the science‑education cloud platform, convened an expert advisory group for the “Science‑Based Seedling‑Strengthening” campaign for winter wheat. The group has compiled an “8 Questions and 8 Answers” guide on spring wheat management, emphasizing a strategy of “early application and early care, with a focus on promoting growth.” It recommends promptly applying foliar fertilizers, including water‑soluble fertilizers containing humic acid, to enhance nutrient uptake through leaf spray.

The Role of Humic Acid Under Various Stress Conditions

A plant is an open system that lives in a natural environment and, as such, is inevitably exposed to adverse conditions. We typically refer to these harmful environmental factors as abiotic stresses or environmental challenges. When such stresses occur, plants undergo a series of physiological and morphological changes: drought can cause leaves and young stems to wilt; waterlogging leads to yellowing and drying of leaves, browning of roots, and even root rot; high temperatures result in leaf browning, the appearance of necrotic spots, and cracking of bark; and pathogen infection produces characteristic disease lesions on leaves. At milder levels, these stresses impair plant growth, development, yield, and quality; at more severe levels, they may even lead directly to plant death. Unlike humans and animals, regardless of the threat they face, plants…

[Soil Conditioner] Good soil, better crops.

Soil conditioners can ameliorate acidic and alkaline soils and enhance the quality of cultivated land.

[Active Humic Acid] Humic acid—activated mineral‑origin humic acid is even better.

Humic acid, derived from nature, returns to nature.
