Water is known as a vital component to sustain life. When one is confronted with the fact that water is considered a renewable resource in the short term but only 3% is usable (N.Gray), precautions must be taken to ensure the conservation of water.
The agriculture industry consumes approximately 70% of the planet’s usable water globally. At large scale the water footprint arguably cannot be reduced, raising the question on whether our water is being used to its full potential.
Water can be manipulated to the advantage of varieties of crops by means of appropriate temperatures that suit the natural and favourable conditions in which the species strive.
The aim of this experiment is to conclude whether or not the agricultural sector …show more content…
This has impacted the temperature of rivers downstream and a decrease in temperature was observed. The decrease in temperature of water used in irrigation has proven to have detrimental effects on the rice yields in Sacramento Valley. The fluctuation in the average water temperature over five days was observed via twelve thermograph stations set up in the Feather River. The change in water temperature raised the question on whether soil temperature will be affected. In the Anderson Irrigation District irrigation water averaged the temperature of 50 degrees Fahrenheit and soil temperature measurement programs were implemented. At lower depths of soil the changes in temperature decreased and has proven to have a temporary effect on temperatures of soil. The yields of Caloro rice decreased due to the fact that the plant only matures when the water temperature is above 70 degrees Fahrenheit, the drop in root temperature caused depressing effects. The yield of root and shoot material of Red Kidney Beans decreased after a similar test was run. Dependant on the type of plant, time cold water was applied and stage of growth, some crops can benefit from a decrease in soil …show more content…
The types of plants experimented with, was not varied and the effects were mainly tested on crops. Article 2:

Summary:
Various plant tissue were used in the conduction of this experiment in order to obtain information concerning the rate of water flow when temperature coefficients were calculated. This was used to observe the effects of water temperature on the water transfer through various plant tissue. The dependence of water flow on temperature was obtained via the data concerning the activation energy of water flow, obtained through the Arrhenius theory. The experiment concluded that water movement through roots and leaves were more complex and easily impacted than viscous flow or simple diffusion.
Weaknesses:
The experiment did not expand on the various types of plants used as well as the differences that would occur when using mesophytes compared to xerophytes or hydrophytes. Article 3:
