Soil Moisture: The Most Important Factor for the Survival of Newly Planted Trees

COURSE DESCRIPTION

The most common cause of death of newly planted urban trees is under- or over-watering. To battle this problem, there are many guidelines written to prescribe how much water should be used. However, none of these prescriptions address the watering application efficiency—i.e., how much water evaporates, runs off, is lost via drainage in porous soils, and is 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 (PAW), no matter how much you irrigate the soil or how much rainwater falls onto it. Soils often becoming compacted after construction projects further complicates this issue. Conventionally, you can’t increase the Field Capacity (FC) without an expensive soil amendment, as it is defined by the texture of the soil.

Join Forester University for this live, educational webinar as returning speaker Wei Zhang (Zynnovation LLC) reviews the key feature of a new irrigation technology: stabilizing soil moisture and significantly boosting the PAW without drowning the plant roots!

This course will also discuss the other factors that may not result in casualty but greatly impact the overall plant health and growth potential—e.g., road salt, girdling roots, and soil compaction.

Relevance to the ongoing COVID-19 pandemic and why it is important to NOT stop planting trees: The COVID-19 pandemic has greatly impacted economics, and it is not over yet. Tax incomes from the local to federal levels have been and will continue to be significantly impacted. We have seen widespread budget cuts or practical cuts by inflation. Historically, grounds, parks, urban forestry, and related programs are the first in the line of budget cut targets. Trees can produce a lot of benefits; 2-5 times their investments based on the US Forest Service. But it takes a long time for them to produce more benefits than the footprint of planting them. The ongoing construction boom is causing canopy loss everywhere. It is so common to see young trees replacing mature trees in development plans. They are not equal. The bigger problem is that governments allow this to happen all the time. “The best time to plant a tree was 20 years ago. The second-best time is now.” Saving costs and increasing the survival rate of newly planted trees can help make a case to decision makers, which will be an important topic of this talk.
