Green Fertilizer Application
Green Fertilizer
Green fertilization is the process of supplying nutrients that are lacking in green grass.
Green City, providing nutrition to the green
Green fertilizer is a process to maintain healthy growth and good green condition by supplementing nutrients that are lacking in green grass based on the annual fertilizer plan.
Fertilizers are divided into granular fertilizer and liquid fertilizer , and the fertilization period is implemented based on the green fertilization plan , but is implemented flexibly depending on weather conditions, grass growth status, and changes in the growing environment.
Equipment and personnel required: 2 manure tanks, 1 Cushman tank, 6 fertilizer spreaders
Time required: 20 minutes for 1 green
caution
- Check if the sprinkler is working before use
- Avoid applying too much fertilizer at once to the greens.
-After watering, check to see if the fertilizer has dissolved sufficiently.
It is not recommended to work at temperatures above -30℃.
How to work
Fertilizer application method
- After checking the type of fertilizer, amount of fertilizer, and location, measure the amount of fertilizer and load it onto the work vehicle.
-After moving to the green, use a fertilizer spreader to evenly spray the fertilizer over the green surface, but make sure to cross the spraying direction at least twice.
-After spraying, use a sprinkler to sufficiently dissolve the fertilizer.
To prevent concentration disorders, water is sprayed immediately after fertilizing one green.
Liquid fertilizer application method
-After checking the type, amount, and location of fertilizer, measure the amount of fertilizer to be applied.
-After filling the tank with water, add fertilizer and dilute it sufficiently.
-After moving to green, one person spreads out the reagent hose and prepares the fertilizer, and the other person starts the fertilizer tank engine, checks whether the PTO is operating, and then adjusts the engine RPM appropriately.
-Do not spray directly on the green, but spray evenly by spraying mist in a 45” to 60” direction.
-After spraying, use a sprinkler to sufficiently dissolve the fertilizer according to the amount and concentration of fertilizer.
- Prevent concentration disorders by spraying water immediately after fertilizing one green.
Types of green fertilizers
- Grain; Grain silica, softening complex, calcium, phosphoric acid, trace elements, soil conditioner
-Liquid: 4 types of compound fertilizers including gari, calcium, silica, zinc, arsenic, iron, wood vinegar, boron, surfactant, etc.

종합 시비관리 :
그린의 시비는 5월 말까지는 복합비료 위주, 6월초에는 액비를 2차례 시비하되 비해 방지와 비료의 용해를 위해 반드시 살수한다.
장마는 평년 기준으로 6월 20일 이후에 시작되므로 장마 2주일 전까지만 액비를 시용하고 그 이후에는 영양제(제 4종복합비료)를 주기적으로 시용한다.
이 때 단일비료(요소, 황산고토, 킬레이트 철, 수용성 칼슘 등)를 엽면시비해 약해진 뿌리의 흡수기능을 보강하면 건강한 잔디생육을 유지할 수 있다.
그러나 배수가 불량 그린의 경우는 1회 시비량을 줄이되 소량 다회 시비법으로 관리하면 침수된 잔디 뿌리에 스트레스를 줄일 수 있다.
8월 중하순경에 일일 최고기온이 25℃ 이하로 하강하게 되면 그린에 복합비료 (21-17-17 기준) 를 15g/㎡ 정도 시용한 후 살수해 여름철에 정체되었던 잔디생육을 회복시킨다.
-잔디 엽색 불량 관리 : 잔디 엽색이 특히 불량할 경우는 EDTA-철 또는 황산철(유산철)을 0.1∼0.2% 농도로 희석해 엽면시비하면 엽색이 회복된다.

The Accelerate controller focuses on providing the operator with more options, specifically the ability to utilize the flow meter calibration process on each boom for increased precision. It also allows for time-catch testing on each nozzle size and color, maximizing precision and accuracy.
Other features have been added, including more precise manual pump speed control, improved spray system pressure valve stability, and expanded diagnostic information such as spray system pressure. Overall improvements to the control software increase the accuracy of the flow meter calibration process, resulting in more precise spraying overall.
