2 cards from this section. Quick, good the night before a test.
What does the variable T represent in the Blaney-Criddle Method?
Think about the conditions contributing to evaporation and transpiration.
What does the variable p represent in the Blaney-Criddle Method?
Consider how light affects plant growth and evaporation.
What variables are used in the Blaney-Criddle Method?
Consider which factors directly influence evaporation rates.
True or False: The Blaney-Criddle Method is the only method for estimating ET.
Remember there are various approaches to estimate ET.
A researcher collects data suggesting that plants in a specific region with an average temperature of 27°C and daylight percentage of 75% yield substantial crops. Calculate the ET and discuss the water needs for maintaining crop health.
Remember to compare ET to actual rainfall.
If you have two separate regions with the same temperature but different daylight percentages, how would you predict their ET values? Set up a calculation and discuss the implications for irrigation management.
Compare differences in ET results due to daylight hours.
