Since manual irrigation being performed during daily life hours, it is difficult to control the timing and amount in such irrigation. If not exerted at the right time and in the right amounts, irrigation will cause serious problems for plant health and development such as saltiness in the soil, leaf burns, fungus diseases, variegations in color, algae growth, and root rot. Irrigation carried out at high temperature in the daytime will cause huge amounts of water loss due to evaporation, and will deteriorate the soil quality and the plant’s nutritive balance.
