Unequal distribution of water and fertilizers. Fertilizer distribution is only as uniform as the irrigation water distribution. Disadvantages of fertigation.
Use pressure gauges to ensure that the center pivot is properly pressured. High degree of automation which can save a lot of labor. Perhaps the biggest uncertainty however concerns irrigation for the 2013 crops.
The type and function of the sprinkler is also very extensive. Evaporation losses can be high. Crops sensitive to stream or crown wetting.
