Answer:
Soil salinity can be reversed, but it takes time and is expensive. Solutions include improving the efficiency of irrigation channels, capturing and treating salty drainage water, setting up desalting plants, and increasing the amount of water that gets into aquifers. Mulches to save water can also be applied to crops.

Answer:
1. The time difference between the arrival of the first P-Wave and S-Wave would be less than 4 minutes.
Explanation:
S waves are slower than P waves, even if emitted at the same time. In this case, we can say that if a station is located close to the earthquake epicenter, the station would receive these waves quickly. The P wave would be received first, since it has a higher speed, the S wave would arrive soon. As you did not provide the times when each wave was emitted, we cannot accurately state the time when each wave would be perceived by the station. However, as the station is close to the earthquake, we can say that the time difference between P and S waves would be seconds, that is, less than 4 minutes.
