Which concept is about ensuring nutrients are available in synchrony with the crop's uptake?

• A. Right Place
• B. Right Time
• C. Right Rate
• D. Right Source

Answer: (B)

Timing fertilizer applications to coincide with the crop’s peak demand means planning when nutrients are in the soil so the roots can take them up when they need them most. This alignment ensures the plant uses nutrients efficiently and minimizes losses from leaching or immobilization. For example, applying nitrogen in split applications during rapid vegetative growth keeps supply in step with uptake, and timing phosphorus around early root development supports strong establishment. While placement, rate, and source are also important, the idea that nutrients are available exactly when the crop can use them best is what the Right Time concept captures.
