摘要：
The impact energy of water droplets from rain or overhead sprinklers can cause a seal to form at the soil surface. This constitutes a severe problem in agricultural lands in arid and semiarid regions. Spreading a soil conditioner on the surface of the soil and providing a constant supply of electrolytes may prevent seal formation. PAM + electrolyte treatments decreased soil erosion by more than one order of magnitude compared with the control. -from Authors
