  • 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 ...
  • Influnce of soil acidification on some soil physical properties (water stable aggregates and dispersion) 
    Manea, Alexandrina; Dumitru, Mihail; Calciu, Irina; Rizea, Nineta (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2011)
    During non-ferrous metallurgical plant from Zlatna were emitted into the air both sulfur dioxide and powder of metal sulphides and metal oxides. Dioxide and trioxide sulfur in contact with rain water converts to sulfuric ...
  • A pedo-transfer function for predicting the physical quality of agricultural soils 
    Vizitiu, Olga; Calciu, Irina; Simota, Cătălin; Pănoiu, Ioana; Manea, Alexandrina (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2012)
    Pedo-transfer functions are mathematical equations that use basic features describing the soil (e.g. particle size distribution, bulk density, organic matter content) in order to predict other properties the values of ...
  • Use of groundwater for irrigation in Romania 
    Vizitiu, Olga; Calciu, Irina (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2017)
    The National Land Improvement Agency has in its administration a number of 296 irrigation systems which cover a total land area of 2998255 of hectares. The main source of water for irrigation systems in Romania is the ...
