How to choose humic acid fertilizer reasonably
2025-05-28 22:08:38
Currently, humic acid fertilizers are still under development, and their product quality inspections are mostly industry and local standards, and application methods vary from product to product.
Sodium humate is mainly formulated into a solution, followed by pouring, seed dressing and foliar fertilizer. Among them, it is formulated as a base fertilizer after being mixed with 0.05%-0.1% concentration, 200-250 kg per mu, preferably mixed with farmyard manure; 150-200 kg for topdressing, applied with water or planted with crop roots. The concentration of soaking or foliar application before planting is 0.05%-0.5%, the soaking time is generally 5-10 hours, and the rice and cotton are 24 hours; the foliar spraying should be carried out after flowering to the early stage of filling, and a total of 2 3 times.
The application method and dosage of ammonium humate are the same as those of sodium humate. Only when the soil has sufficient water and irrigation conditions, the fertilizer effect can be fully exerted.
A fertilizer containing humic acid water-soluble is added with an appropriate amount of nitrogen, phosphorus, potassium or trace elements in humic acid. In the application method, the water-soluble solid or liquid product is mainly used as a foliar fertilizer, a seed fertilizer or a seed soaking, and a root soaking. The specific method can refer to the product specification, and it is generally diluted about 800 times. A large amount of elemental humic acid-containing water-soluble fertilizer can also be used for base fertilizer or top dressing, but due to the high cost and limited application amount, it should be applied in combination with farmyard manure and conventional chemical fertilizer.
Humic acid fertilizer is used as the base fertilizer and the seed fertilizer is better than the top dressing. The concentration is better than that of the application. The deep application is better than the shallow application. At the same time, humic acid fertilizer can not completely replace inorganic fertilizer and farmyard manure, and must be combined with chemical fertilizer and organic fertilizer application, especially with phosphorus fertilizer.
Different types of fertiliser materials have different input ratios, different manufacturing methods, and different nutrient contents. It is necessary to control the appropriate concentration when applying.
Potassium humate and sodium humate are mostly hormonal fertilizers. After application, the cold effect is slow, the heat is effective, and the suitable temperature needs to be effective for more than 18 hours. If the temperature is higher than 38 °C, it will accelerate the respiration of crops and reduce dry matter. Accumulation, resulting in reduced production, should stop application or reduce the number of applications and dosage.
