Several factors influencing infiltration were taken into consideration. The impact energy of water drops can cause surface sealing and crust formation, reducing soil infiltration and thus increasing runoff. Kinetic energy (Jm−2 mm−1) and specific power (W m−2) were computed based on the drop velocities from the sprinklers using the methodology presented by King and Bjorneberg (2010). Wind can also affect infiltration tests. Wind deviation of applied water modifies the water application rates, and increases the impact velocity of drops. To avoid the influence of this factor, all tests were carried out in the morning when the wind speeds less than 0.1 m s−1, measured at the field location with a portable anemometer. Infiltration rate can also be affected by soil water content. Volumetric water content was measured gravimetrically before irrigation in three different positions along each soil box in the first 5 cm of the soil surface
