In today's pursuit of efficient and sustainable agricultural and horticultural practices, granular humic acid has become a key tool for improving soil health and increasing crop yields. As an organic soil conditioner made from natural raw materials like Leonardite, it supports plant growth by enhancing soil structure and promoting nutrient absorption. The correct application of humic acidgranular products can significantly increase fertilizer use efficiency, stimulate root development, and enhance crop stress resistance. This article provides a comprehensive guide on how to use granular humic acid efficiently and safely, helping you maximize its benefits.

• Base Application: Before sowing, evenly broadcast the granules on the soil surface (recommended rate: 30-50 kg per mu, approx. 50-75 kg/hectare) and mix into the soil through plowing. This helps improve soil aggregate structure and water retention.

• Top Dressing Management: During key growth stages (e.g., jointing, grain filling), apply the granules in furrows or holes mixed with NPK fertilizers, which can increase fertilizer use efficiency by over 40%.

• New Lawns: Before seeding, incorporate the granules into the topsoil at a rate of 1-3 kg per 100 square meters to promote seed germination and root establishment.

• Routine Maintenance: Apply 1-2 times per quarter during the growing season at 10-15 grams per square meter. Water thoroughly after application to help the granules dissolve and penetrate to the root zone.

• Fruit Trees: Apply 1-2 kg per tree by trenching around the root zone, mix with organic fertilizer, and cover with soil. This can increase the sugar content and color of the fruit.

• Vegetables: For leafy vegetables, apply 10-15 g/m² as top dressing; for fruiting vegetables, 15-20 g/m² can be used. Irrigate to promote dissolution and absorption.

• Seasonal Timing: Apply in spring when soil temperature stabilizes above 10°C to activate microbial activity; autumn application helps roots store energy for winter.

• Growth Stages: It is recommended to apply twice during key stages such as after transplanting, flower bud differentiation, and fruit expansion.

• Base Soil Application: Incorporate granules evenly into the soil during deep plowing to a depth of 15-20 cm, ideal for improving compacted or saline-alkaline soil.

• Side Dressing/Hole Application: For perennial crops, trench around the root zone and bury the granules, avoiding direct contact with roots.

• Irrigation Integration: Add granules to drip or sprinkler irrigation systems at a dilution concentration of 0.01%-0.05% to achieve integration of water and fertilizer.

III. Why Choose GreenTop Granular Humic Acid?

• Slow-Release Technology: Uses micro-encapsulated controlled-release technology for a nutrient release cycle of up to 90 days, avoiding the risk of short-term overloading.

• High-Activity Ingredients: Sourced from deep-layer natural Leonardite, with a humic acid content of 60%-70%, rich in active functional groups like carboxyl and phenolic hydroxyl groups.

• Optimized Physical Properties: Granule particle size is controlled at 2-3 mm, with a uniformity distribution exceeding 92%, ensuring dust-free application and more complete dissolution.

• Application Environment: Avoid application during hot, dry, or heavy rain conditions; application when the soil is moist yields better results.

• Compatibility: Can be mixed with most chemical and organic fertilizers, but a small-scale compatibility test is recommended first to avoid caking or reactions.

• Safety: Products are certified for ecotoxicity and are safe for pets, soil microorganisms, and the environment.
