The healthy growth of the lawn depends on a variety of nutrients, although the soil already contains these nutrients, but it needs to continue to "tonic."
First, the use of appropriate fertilizer nitrogen is not only the highest element in the plant, but also the most needed nutrients, followed by potassium and phosphorus. These three kinds of elements are very important to the growth and development of plants and to the recovery of growth, but too much or too little content can cause growth problems. The timing, amount, and method of fertilization are also very demanding.
Due to differences in climate, soil, and grass species, a fertilization scheme cannot be applied to all lawns, but there are still general principles. For example, nitrogen fertilizers are generally divided into quick-acting and slow-release nitrogen fertilizers. Fertilizers will be fattened if the amount of available N fertilizer is too large. Conversely, if only slow-acting nitrogen fertilizers are used, the turfgrass may grow slowly under favourable growth conditions, being more vulnerable to growth and being more vulnerable in adverse environments. Therefore, the ideal fertilization method lies in the combination of quick-acting and slow-acting nitrogen fertilizers. Most high-quality turfgrass fertilizers contain the above two types of nitrogen fertilizer and can meet the daily nutrient needs of the plant for a longer period of time (generally 6 to 12 weeks). Fertilizer's trademark will generally indicate the fertilizer effect of the product and the type of nitrogen fertilizer contained. If the above information cannot be found on the product packaging, do not purchase it. In addition, it must be noted that the price of slow-acting nitrogen fertilizer is higher than that of available nitrogen fertilizer.
Second, the best timing of fertilization In short, the lawn should be fertilized when good growth, otherwise it does not need fertilization. When the environmental conditions (temperature, moisture and sunshine) are poor, the fertilizer does not grow the turf. The best growth temperature for cool-season grass is between 15.5°C and 26.5°C. Under the northern climate conditions, the spring and autumn seasons are usually in a strong growth period, while in the midsummer, the growth is slow. Warm-season grass grow best when the temperature is higher than 26.5°C, and should be fertilized during the vigorous growth period.
Third, the correct application of chemical fertilizer Fertilizer can not guarantee the application of fertilizer effect, so the correct method is to apply the appropriate amount of fertilizer in the right place. The most commonly used fertilizing tools are liquid sprayers, liquid applicators, and rotary or spreader applicators. The sprayer is easy to use, but it is difficult to apply fertilizer evenly. The liquid fertilizer applicator is convenient for setting speed, but it must be ensured to cover the entire lawn. The rotary fertilizer applicator is currently the most effective and accurate fertilizing device and can quickly apply fertilizer to a large area. In order to achieve the best fertilization, it is important to note the following:
1. Buy a high-quality fertilizer applicator, familiarize yourself with the function of the applicator, and clean it after using the applicator. Turn on the applicator before turning on the applicator and turn off the applicator before stopping.
2. Fertilize when the grass grows well.
3. Set the fertilizer applicator according to the requirements on the fertilizer label.
4. All lawns must be applied and do not miss.
5. Avoid using large-sized fertilizer products when using rotary fertilizer applicators.
6. Watering immediately after fertilization can improve fertilizer efficiency, and it is best to fertilize before raining
