| Abstract |
Subsurface irrigation even without heating the soil has given good results in terms of increased yields of crops and decreased water requirements in comparison with other methods of water application. Laboratory experiments were used to study the effect of heat source temperature on the temperature distribution around a line heat source in different soils. Different soil surface heat loads were applied to study the effect of varying climatic conditions on the temperature distributions. Concurrent experiments were conducted to determine the effect of lowering root temperature on plant growth by measuring the effects on plant water potential and its relation to leaf elongation, photosynthesis, and transpiration, using young corn plants. |
