Northern green planting cool season turfgrasses are grasses, require nitrogen and potash fertilizer more. Turfgrass 70% to 80% of the roots spread in shallow soil depth of 20 cm, weighing perennial grass cover on the soil surface, and therefore, in addition to administering basal formed when the lawn, not mid-plowing deep base fertilizer. Only lawn fertilizer during the growing season, or the fertilizer evenly spread on the roots at or in conjunction with the water spraying fertilizer. Therefore, we must have a relatively large amount of nitrogen, potassium and phosphorus, but also to the dressing method based, gentle and continuous supply of nutrients. For the finest green lawn, the total recommended fertilization year: the equivalent of 13 to 16 kg net nitrogen / acre (20 to 25 grams / square meter), net phosphorus from 6 to 8 kg / acre (10 to 12 g / m2) net potassium 12 to 13 kg / acre (20 grams / square meter). In the fertilizer of choice, quick result when using elemental fertilizer, phosphate fertilizer once a year, nitrogen and potash to be a few times, at the end of March to the end of the season fertilization 10 years, except during July and August, hot and rainy less nitrogen fertilizer is not applied In addition, generally applied once a month, the annual nitrogen minutes 7-8 times Shi, potash applied four to five times. If selected compound fertilizer, to choose the proportion of nutrients nitrogen and potassium-based, less fertilizer containing phosphorus. On the fertilizer particle morphology, preferably in small particles, fertilizer granules should not be too large. However, due to stick to grass powdery fertilizer and should not be administered. Can also be a small amount of decomposed manure or peat mix granulated use as carrier. In recent years, in order to achieve sustainable and balanced supply of turfgrass nutrition, high-quality international market will slow, controlled release fertilizers for lawns, which has slightly soluble in organic synthesis and polymer coated fertilizer granules coated compound fertilizer urea or dedicated with this kind of fertilizer can reduce the frequency of application, and to achieve sustained moderate nutrient supply purposes. There are also individual success fat wrapped package of fertilizer fertilizer production, are effectively used to fertilize the lawn. Unbalanced fertilization is common. For cool-season grass, it should spring and more fertilizer, especially in the summer and less control of nitrogen fertilization. And in some places more or summer of nitrogen, resulting in excessive growth of turfgrass breeding and disease, and then late autumn lawn grass decline. In addition, the proportion of NPK fertilizer, there is a bias is applied both too much nitrogen fertilizer, such as are used in many places biased urea, rather than focus on a balanced fertilizer NPK fertilizer, resulting in yellow leaves appear leggy stems soft phenomenon . At the same time, there is also improper proportion of fertilizer nutrients, for example, large selection of general-purpose 45% (15% to 15% to 15%) of compound fertilizer, phosphate fertilizer application problems caused by excessive. Both consequences both to improve the cost and pollution of water and the environment. To smooth and continuous supply of nutrients. Fast-acting fertilizer should be administered a few times.
