The healthy growth of the lawn depends on a variety of nutrients, and although the soil already contains these nutrients, it still needs to be “tonicâ€.
First, the selection of suitable fertilizer nitrogen is not only the highest content of plants, but also the most needed nutrients, followed by potassium and phosphorus. These three elements are essential for the growth and recovery of plants, but too much or too little will cause growth problems, and the timing, dosage and method of fertilization are also very particular.
Due to differences in climate, soil and grass species, a fertilization scheme cannot be applied to all turf, but there are general principles. For example, nitrogen fertilizer is generally divided into quick-acting and slow-release nitrogen fertilizers. If the amount of quick-acting nitrogen fertilizer is too large, it will cause fat damage. Conversely, if only slow-acting nitrogen fertilizers are used, the turf may grow slowly under favourable growth conditions and may be more susceptible to adverse conditions due to poor growth. Therefore, the ideal fertilization method is the combination of quick-acting and slow-acting nitrogen fertilizers. Most high-quality turf fertilizers contain both types of nitrogen fertilizers, which can meet the daily nutrient needs of plants over a longer period of time (typically 6 to 12 weeks). The fertilizer's trademark generally indicates the fertilizer effect of the product and the type of nitrogen fertilizer. Do not purchase if the above information is not found on the product packaging. In addition, it must be noted that the price of slow-acting nitrogen fertilizer is higher than that of quick-acting nitrogen fertilizer.
Second, the best time to fertilize In short, the lawn should be fertilized when the growth is good, and vice versa without fertilization. When the environmental conditions (temperature, moisture and sunshine) are not good, the fertilizer does not grow the lawn. The optimum growth temperature for cold-season grass is between 15.5 °C and 26.5 °C. In the northern climatic conditions, spring and autumn are generally strong growth periods, while in summer, growth is slow. Warm-season grasses have the best growth at temperatures above 26.5 °C and should be fertilized during vigorous growth.
Third, the correct application of chemical fertilizers improper application of fertilizer can not guarantee the effect of fertilization, therefore, the correct method is to apply appropriate fertilizer at the right place. The most commonly used fertilizing tools are liquid sprayers, liquid fertilizer spreaders and rotary or spreader spreaders. The sprayer is easy to use, but it is difficult to apply evenly. Liquid fertilisers are convenient at setting speeds, but must be covered to cover the entire lawn. The rotary fertilizer applicator is currently the most effective and accurate fertilizer application device, which can quickly apply fertilizer to a large area. In order to achieve the best fertilization effect, we must pay attention to the following points:
1. Purchase a high-quality fertilizer application machine, familiar with the function of the fertilizer application machine, should be cleaned after using the fertilizer application machine, before starting the fertilizer application machine, the first step should be started, and the fertilizer application machine should be shut down before stopping.
2. Fertilize when the lawn grows well.
3. The fertiliser is set according to the requirements on the fertilizer label.
4. All lawns should be applied all the time, don't miss them.
5. Avoid using large-grain fertilizer products when using a rotary fertilizer applicator.
6. Watering immediately after fertilization can improve fertilizer efficiency, preferably before fertilization.
