Reasonable top dressing of lawns. Lawn special fertilizers are based on the growth characteristics and nutrient demand characteristics of various types of grass and grass seeds (football lawns, golf lawns, green lawns) and the requirements of non-pollution and non-pollution. Active biological fertilizers are adjusted in a targeted manner. Bacteria, organic matter and trace elements, etc., make the fertilizer effect have the special function of having both quick and long-term effect, integrating microorganisms and organic nutrients, organic matter and special-effect bacteria to jointly display the fertilizer effect. Spring can promote lawn growth, and autumn can promote the accumulation of dry matter and extend the greening period
The application of lawn special fertilizer is generally ./square meter, mainly considering the input cost and the color of the lawn. Generally, if the lawn does not turn yellow, fertilization is not required. If the soil quality is poor, small amounts and multiple times are required.
Fertilization time Lawn fertilization time is affected by factors such as bed soil type, seasonal changes in lawn utilization purposes, atmospheric and soil moisture conditions, and the amount of grass clippings after lawn mowing. Theoretically, there are three fertilization periods for lawns in a year: spring, summer and autumn. Generally, cool-season lawns require higher nutrient levels in early spring and rainy seasons, and the most important fertilizing times are late summer and late fall. High-quality lawns are best fertilized once or twice in the spring. Warm-season turfgrass requires higher amounts of fertilizer in summer, and the most important fertilization time is late spring. The second fertilization should be arranged in early and mid-summer, and fertilization in early spring and late summer is also necessary.
In addition, the timing of fertilization can also be determined based on the appearance characteristics of the lawn, such as leaf color and growth rate. Fertilizer should be applied when the lawn is noticeably chlorotic. During the growing season, when the color of the lawn grass is dull, yellow, and the old leaves are dead, nitrogen fertilizer is needed. If the leaves are red or dark green, phosphorus fertilizer should be supplemented. The nodes of the lawn grass are shortened and the leaf veins are yellow. When the old leaves are dead, potassium fertilizer should be added.
A reasonable fertilization plan is formulated based on a full understanding of the supply and demand relationship of nutrients for the lawn, as well as the types, properties, usage methods, etc. of the required fertilizers. There is no fixed fertilization plan to choose from for any lawn. . The basic principles and suggestions for fertilization mentioned above can be used as a reference for lawn managers. Turf managers need to find the most suitable fertilization plan in practice based on their actual conditions.
