At different stages of chilli cultivation, the proper application of two organic acids — humic acid and fulvic acid — can help improve crop yield. Each has its own unique characteristics and functions.

The Role of Humic Acid and Fulvic Acid

The main function of humic acid is to improve soil structure. It promotes the formation of soil aggregates, improves soil aeration and water retention, and increases the utilisation rate of fertiliser and water.

Humic acid also helps create a balanced rhizosphere environment for crops, thereby promoting root development. A well-developed root system not only improves the plant’s ability to absorb nutrients, but also strengthens the resistance of chilli plants.

Fulvic acid can increase the organic matter content in soil and improve the soil’s nutrient-holding capacity. It also helps stimulate the activity of beneficial microorganisms in the soil. These microorganisms can break down organic matter and release nutrients needed by plants, strengthening the soil ecosystem and promoting plant growth. This supports the healthy growth of chilli plants and improves both yield and quality.

Synergistic Effect to Improve Fertiliser Efficiency

Advansia’s Axtra Roots is a high-quality liquid plant fertiliser containing humic acid and fulvic acid. Before transplanting chilli seedlings, Axtra Roots can be mixed at 100ml with 20 litres of clean water and applied into the soil thoroughly and evenly. This helps improve soil structure, increase soil organic matter, and prepare a suitable growing environment for seedlings.

During the chilli growth stage until flowering and fruiting, it is also recommended to mix Axtra Roots at 100ml with 20 litres of clean water every two weeks and apply it to the crop root zone as a soil drench. Axtra Roots can also be used together with other chemical fertilisers and organic fertilisers to provide a synergistic effect and further improve fertiliser efficiency.

With proper application, it can not only improve yield, but also enhance fruit quality and increase economic benefits.
