Advanced Irrigation Management for Container-Grown Ornamental Crop Production

  Container-grown plants are constrained with regard to root growth, and are affected by factors including container size, substrate, weather, nutrition, and irrigation. Typical soilless substrates will hold less plant-available water than a typical field soil, making water management a...
