Irrigation was applied using drip sprinklers until soil moisture capacity was reached.
Advantages of drip over sprinkler irrigation are that it uses less water, lessens disease by not wetting the foliage and can be easily automated.
First of all, Jack Keller, who has written the classic texts on drip and sprinkler irrigation [some of his work is here] and who Jen probably also knows, is also an active participant in the design team.
There were no significant differences between the drip and sprinkler irrigation concerning the root biomass.
Then, the controller creates a program for loading and communicating automatically with drip or sprinkler system controllers.
In some arable crops like cereals that are not irrigated by either drip or sprinkler irrigation, the root application of Fe chelates in aqueous solutions is rather complicated and thereby their application along with NPK fertilizer granules has great interest.
The experiment was designed as a split plot design with four replicates, two main plots (drip and sprinkler irrigation) and three sub-plots (vetch as green manure, red clover as green manure and control; without fertilization).
The results of this study indicate that flood irrigation using arsenic-contaminated groundwater should be controlled and gradually replaced by drip irrigation, sprinkler irrigation or irrigation using non-contaminated water resources to mitigate arsenic accumulation in the unsaturated zone and shallow groundwater.
Improvement of sub-surface drainage conditions, deep cultivation procedures, reclamation, leaching and drip, or sprinkler irrigation is the important land developmental activities, which improve the soil texture as well as soil salinity and water salinity, for facilitating the irrigation easier (Ayers and Westcot 1985).
He cannot afford to invest in drip irrigation or sprinkler systems that would lose less water to evaporation.
