Worksheet time: 5mins
Which factor is closely affected by plant nutrition in citrus production?
Soil erosion
Fruit quality
Pest resistance
Water usage
What can result from applying too much readily soluble fertilizer to crops at once?
Increased growth rate
Plant toxicity
Enhanced fruit flavor
Better pest resistance
What is suggested to avoid leaching of nutrients when using soluble fertilizers?
Apply in large doses
Split into smaller doses
Use only in dry conditions
Mix with pesticides
What is a potential issue with using soluble fertilizers in granular form?
Slow nutrient release
Quick nutrient leaching
Increased pest attraction
Reduced soil fertility
What is one advantage of Controlled Release Fertilizers (CRFs)?
They increase the frequency of fertilizer applications.
They reduce environmental impact.
They decrease the supply of nutrients.
They increase plant toxicity.
What do CRFs typically control to affect nutrient release?
Soil color
Plant height
Rate, pattern, and duration of nutrient release
Leaf size
What is the purpose of backflow prevention devices in irrigation systems?
To increase water pressure
To prevent contamination of water by applied chemicals
To reduce the cost of irrigation
To increase the speed of water flow
How long should water travel from the injection point to the farthest emitter in microirrigation systems?
5 to 10 minutes
10 to 15 minutes
20 to 30 minutes
40 to 50 minutes
What happens if cloudiness occurs in the fertilizer solution within two hours?
The solution is ready for use.
The solution is too diluted.
There is a chance of line or emitter plugging.
The solution is too concentrated.
Why is foliar feeding particularly important in areas with poor water quality?
It reduces water usage.
It enhances the effectiveness of nutrient uptake.
It improves soil drainage.
It increases plant resistance to pests.
