  • Contributions regarding knowledge of soil aeration processes to plant growth and development 
    Voicu, Petre; Calciu, Irina; Vizitiu, Olga (“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2022)
    In this paper, the potential aeration conditions of the soils are studied, which are particularly important in establishing their fertility status necessary for optimal plant development. The indicators that define the ...
  • Evaluation of soil water regime in the viable irrigation systems from Romania 
    Calciu, Irina; Vizitiu, Olga; Răducu, Daniela (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2017)
    The aim of this study was to evaluate the active soil moisture range, soil water deficit, and water requirements for plant consumption at agricultural parcel level (NUTS5) where irrigation is applied. In order to evaluate ...
