Abstract To exploit the full potential of plants, it is essential to provide an adequate water balance during critical growth stages. With knowledge substrate’s matric potential, possible realistically measure amount available plant. The objective this research study effect substrate on beans, lettuce, sweet peppers, watermelon, and cauliflower plants. goal was evaluate main fertigation paramet...

The aim of this work is to study the sensing behavior of Sr-doped hematite for soil water content measurement. The material was prepared by solid state reaction from commercial hematite and strontium carbonate heat treated at 900 °C. X-Ray diffraction, scanning electron microscopy and mercury intrusion porosimetry were used for microstructural characterization of the synthesized powder. Sensors...

A capillary-driven root module design for growing plants in microgravity is presented. Matrix-based root modules have been developed for conditions of microgravity which require active pumping or an elaborate control system to operate. The capillary-driven system is passive and relies on root uptake to develop the necessary gradient within the media to operate the liquid control valve. A collap...
