some tips for saving water in agricultural practices include which of the following? select all that apply.
use mulch to cover soil and reduce evapotranspiration
use flood irrigation to insure crops are hydrated
agroforestry - plant trees to help shade crops and livestock
plant drought - tolerant crops

Explanation:

• For the first question: Groundwater is renewable when replenishment rate is at least equal to pumping rate. If it's greater, it's still sustainable (renewable). If less, it depletes (non - renewable).
• For the second question:
• Mulch reduces evapotranspiration (saves water).
• Flood irrigation is water - intensive (not a saving tip).
• Agroforestry with tree shading can reduce water loss (saves water).
• Drought - tolerant crops need less water (saves water).

Answer:

First question: A. equal to, C. greater than
Second question: A. use mulch to cover soil and reduce evapotranspiration, C. agroforestry - plant trees to help shade crops and livestock, D. plant drought - tolerant crops
