Use & Application
1. Seed dipping
Soaking seeds can improve seed germination rate, early emergence and enhance the ability of seedlings to send out roots. The general seed soaking concentration is 0.005%-0.05%, the general soaking time is 5-10 hours, rice, cotton, and other hard-shelled seeds for 24 hours.
2. Dip the root, dip the root
Rice, sweet potatoes, etc. before transplanting can be used to dip seedlings in humic acid na or potassium humate solution, the concentration of 0.01% -0.05%. After dipping seeds show fast root development and a high survival rate.
3. Spraying outside the root
The general concentration of 0.01%-0.05% solution, sprayed 2-3 times during the flowering period of the crop, the spraying time should be chosen in the afternoon 2-4 pm good results.
4. As a base fertilizer
Solid humic acid fertilizer (such as ammonium humate, etc.) can be mixed with agricultural fertilizers in the application, ditching, or hole application can be.
5. As chasing fertilizer
In the crop seedling stage and before the tassel stage, watering in the vicinity of the crop root system. Water fields can be applied with irrigation or splashed on the water, can play a role in raising seedlings, strong seedlings, and promote growth and development.
Classification
1.Solid humic acid fertilizers
Solid humic acid fertilizers mainly include ammonium humic acid, sodium humic acid, potassium humic acid, and humic acid compound fertilizers. According to the needs of agricultural production, various micronutrient fertilizers and some bacteria beneficial to soil and crops are added to humic acid.
2.Liquid humic acid fertilizers
The varieties of liquid humic acid fertilizers are similar to solid fertilizers, only that they are different in form. Instead, it is applied in the form of a spray, with trace elements directly in the plant through the crop leaves for the purpose of providing nutrients. The emergence of this type of fertilizer has brought simplicity to production and a much higher utilization rate.
Cautions
Soil conditions: lack of organic matter, the effective nitrogen content of the soil application of humic acid fertilizer effect is good; acidic soil, clayey soil, slaty soil application effect is also good. However, the effect of strong acidic soil is not good, need to apply lime to adjust. The high organic matter and nitrogen content of the soil application effect is not obvious.
Moisture conditions: fertilizer effect can only be produced if there is sufficient moisture. Because humic acid fertilizer can only show its physiological activity in a water-soluble state. Therefore, it should be combined with irrigation when applied in a dry land.
Temperature: It is difficult to show the effect when applied below 18℃.
Concentration: Liquid humic acid fertilizer, too high concentration will inhibit plant growth, too low and does not work. The specific concentration is determined by the plant species and fertility period.
When purchasing humic acid fertilizer, pay attention to its nutrient content, production period, application amount, and application method to avoid adverse consequences caused by improper use.
Significance of Environmental Protection
After repeated tests, compared with common fertilizers, humic acid can achieve a slight increase in crop yield despite a 20% reduction in usage; at the same time, humic acid can improve the utilization rate of fertilizers from 30% of common fertilizers to more than 40%~45%, and the interaction between the two can greatly reduce the usage of fertilizers, reduce energy consumption, and reduce the harm to the ecological environment caused by the waste of fertilizers.
The good effect of humic acid on crop robustness can improve the crop’s resistance to pests and diseases. At the same time, doraagri integrates humic acid technology with functional bacteria biocontrol technology to reduce the use of pesticides. It plays a good role in the safety of agricultural products.
