Principles of Drip irrigation

October 12 - October 15, 2012
We intensively covered drip irrigation:

Drip irrigation (sometimes called trickle irrigation) works by applying water slowly, directly to the soil, bloop, bleep, bloop, bleep. The high efficiency is that the water soaks into the soil before it can evaporate or run off, and the water is only applied where it is needed, (at the plant's roots) rather than sprayed everywhere. 
 While sprinkler systems are around 75-85% efficient, drip systems typically are 90% or higher. Less wasted water with drip irrigation. It is easy to install, easy to design, can be very inexpensive, and can reduce disease problems associated with high levels of moisture on some plants.

In brief, drip irrigation’s benefits are that it uses less water
It dries mid rows and foliage, pesticides are not washed off, it fertilizes through the drip system, it provides precision placement of water, It is used under mulches, it provides water uniformly, and it is not influenced by wind. Problems encountered with drip irrigation are the clogging of particles, water quality, the expense of lines and tubes, determining how much to water, and the time and money to install them.
