Product features
1. It can be combined with elements such as nitrogen, phosphorus, and potassium to produce humic acid fertilisers, which can increase the organic matter content in the soil and have functions such as fertiliser efficiency enhancement, soil improvement, stimulating crop growth, and improving the quality of agricultural products.
2.Adjust soil acidity and alkalinity to increase soil fertility. Crops are suitable for soil environments with a pH range of 5.5 to 7.0, and the pH of humic acid can be directly applied to the crop environment, balancing the soil environment. Humic acid can greatly stabilise the storage and release of nitrogen elements, decompose phosphorus and potassium fixed in the soil, promote the absorption and utilisation of other trace elements by plants, and promote the activity of beneficial bacteria, thereby helping to establish a soft soil structure, improve binding and water-holding capacity, and improve soil fertility.
Application method: ditch application, hole application.
