The LER in Pasture.io not only calculates each day the LER, but it also supplies a rolling 14-day forecast.
The models ingest a lot of data and most of that data is procured. Weather is one such source and is the largest driver for the LER.
Leaf appearance rate is influenced by weather data and modelled growth conditions. If it looks unusual, it may be due to changing weather inputs, forecast updates, or local conditions (see below for futher explanation). Use it as a guide alongside pasture cover, grazing history, and your own farm knowledge.
Just look at the 14-day rolling forecast for the Leaf Emergence below:
Now, if we pull up one of the weather sources that feed the LER model, we can see that there is an anomaly in the weather data we are receiving from one of the suppliers.
The best thing we can do is sit tight for a few days or more and ride out what is being reported. Thankfully, the LER is more about the long term trend than a knee-jerk reaction.
