How long does it take for water-soluble fertilizer to take effect, and how long does its efficacy last?

  As more people learn about the characteristics and benefits of water-soluble fertilizers, their adoption among growers has significantly increased. Everyone has come to recognize the advantages these fertilizers offer. Water-soluble fertilizers are fast-acting, highly water-soluble, and enable more flexible application methods, effectively reducing labor costs. Additionally, they provide comprehensive nutrients that directly support crop growth. So, how long does it take for water-soluble fertilizers to take effect? How long does their nutrient release last? And what is the proper application method?
  Typically, effects become visible within 3-5 days after application, with crop growth showing significant improvement compared to before. If the water-soluble fertilizer shows results on the same day or the next day, it is likely a hormone-based product, which should be avoided whenever possible. Applying water-soluble fertilizer as a top dressing during the crop's rapid growth phase yields very noticeable results.
  Regarding the duration of fertilizer effectiveness, this is influenced to some extent by climate conditions. Typically, the effective period lasts around 15 days. However, in winter or high-temperature environments, the duration tends to be shorter.
