Which elements are required by trees in large quantities?

Water Holding Capacity
Macronutrient
Sand
course textured particles

The correct answer is: Macronutrient

Trees require macronutrients in large quantities for their growth and development. Macronutrients are essential elements that trees need in relatively large amounts compared to micronutrients. These macronutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Water holding capacity, sand, and coarse textured particles are not elements required by trees in large quantities for their growth and development.
