Event Registration - Soil Moisture: The Most Important Factor for Young Tree Survival logo1.jpg
Wednesday, February 17, 2021
2:00 PM - 3:00 PM Eastern Standard Time
The most common cause of death of newly planted urban trees is under- or over-watering. Watering prescriptions are developed to solve this problem. However, none of these prescriptions addresses the watering application efficiency: How much water evaporates, runs off, is lost via percolation and consumed by weeds instead of the tree? Without this information, the amount of water applied to trees means little. At the same time, most irrigation systems are designed for lawns, not for trees, which need much deeper watering. The real limitation is in the plant available water, no matter how much you irrigate the soil or how much rainwater falls onto it. Conventionally, you can't increase the field capacity without an expensive soil amendment, as it is defined by the texture of the soil. This webinar will review the key features of a new irrigation technology: stabilizing soil moisture and significantly boosting the plant available water without drowning the plant roots.
This webinar is worth one CEU in the Tier 1 - Irrigation Training category.
