Determining the correct amount of nutrients for a fresh market tomato crop is relatively easy. A soil sample is taken and analyzed, and a nutrient recommendation is made based on Cooperative Extension production guidelines. However, knowing correct rates is only one piece of the puzzle. Growers must then ensure that a tomato crop has the correct amounts of nutrients in the correct placements at the correct times. Great care must be taken in delivering nutrients to the plant and ensuring that the plant has sufficient moisture for nutrient uptake and utilization.
