The first experimental system of this type was established in 1959. In the early 1960s, Blass developed and patented this method and the new dripper was the first practical surface drip irrigation emitter. During the years 1960 to 1965 Blass developed the drip-irrigation systems and sold them inside Israel and abroad.
By considering a long-term (e.g. seasonal) average depth of the water table (Dw) in combination with the long-term average recharge rate (R), the net storage of water in that period of time is negligibly small and the steady state condition is satisfied: one obtains a dynamic equilibrium. Derivation of the equation
Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.
Salinization - Depending on water quality irrigation water may add significant volumes of salt to the soil profile. While this is a lesser issue for surface irrigation compared to other irrigation methods (due to the comparatively high leaching fraction ), lack of subsurface drainage may restrict the leaching of salts from the soil.
A one-US-gallon-per-hour (3.8 L) drip flow controller feeding an 82-foot-long (25 m) drip line with check valves comprising 82 drip points along its length so each drip point is putting out about 1 / 82 US gallon (46 mL) per hour. Crimson clover sprouts grown on 1 / 8-inch (0.32 cm) urethane foam mats and flagstone.
