Root-zone temperature effects on the nutrient uptake of horticultural crops
… horticulture crops often are subject to root-zone temperatures (RZT) that exceed 30C, but little is known about the effects of supraoptimal RZT on nutrient absorption. In my first study, I determined the amount of phosphorus (P), zinc (Zn), and manganese (Mn) in tomato (Lycopersicon …

An open source controlled environment agriculture platform : exploration of root zone temperature effects and thermal management
… platform was built with air and water temperature control systems. Caesar basil seedlings were grown in the GRObot with a shallow water culture hydroponic system for two-week periods. In the first trial, the root zone temperature (RZT) was allowed to fluctuate with the air temperature …

Influences of supraoptimal root-zone temperature on the medium solution and growth of woody nursery crops
The effects of high medium temperatures on the growth and mineral nutrition of selected woody plants and on the composition of the medium solution were studied. Medium temperature profiles were established for 3.8-liter black polyethylene containers exposed to solar radiation under Virginia nursery …

Effects of Air vs. Air+Soil Heating During a Simulated Heat Wave on White Oak (Quercus alba) and Black Oak (Quercus velutina)
… heating in woody species, we manipulated the temperature of both shoots and roots separately for both white and black oak seedlings by insulating the soil during heat-stress to the shoot (35 <i>vs.</i> 40°C for 4 days, white oak; 35°C for 8 days, black oak). Interestingly, at moderate …
