On a greenhouse visit some time ago, I asked a new grower, “What fertilizer rate are you using?” To my surprise he replied, “I don‘t know.” I left the greenhouse fairly concerned, but after some contemplation decided that perhaps I shouldn’t be. Why? Because the fertilizer rate a grower provides to a crop is only one component affecting the crop‘s nutritional status. Factors such as fertilizer source, leaching fraction, irrigation method and plant development stage can dramatically affect the fertilizer rate that is necessary.
