SMART WATER AND SOIL-SALINITY MANAGEMENT IN AGRO-WETLANDS Autori: Marinella MasinaData aparitiei: Octombrie / 2019 Revista: Environmental Engineering and Management Journal › Vol. 18 › Nr. 10 ISSN: 1843 - 3707 N.A.
Soil salinization is becoming worldwide one of the most serious land degradation issues. Seawater intrusion in upper aquifers is responsible for the largest proportion of salt-affected agricultural lands in coastal areas. In this study, the impact of different irrigation strategies on the salinity of a maize cultivated field located in the coastal plain of Ravenna, Italy, was simulated with the FAO AquaCrop model. Model calibration was supported by comparison with remote-sensed and field collected crop data. Ten irrigation scenarios were tested by varying the irrigation season length, the soil moisture threshold for irrigation (TI), and the irrigation depth (ID), in presence or absence of flooded pipe drains (FD) to create a fresh-water lens preventing salt rising from brackish groundwater. |
