“…The 12 000 cm 3 of soil for each pot (22.5 cm in height, 28.5 cm in diameter) was taken from the arable soil layer (30 cm depth), sifted to eliminate plant remains and large soil aggregates. The soil is classified as anthropogenic eutric cambisol (WRB), silty clay loamy texture with following physical properties in upper soil layer: 64.7% silt, 32.5% clay, 2.8% sand, 44.8% porosity (P), 36.6% available water holding capacity (AWC), 5.2% air capacity (AC), 39.52% saturation (SAT), 23.7% permanent wilting point (PWP), and 2.75 g/cm 3 partical density (Marković et al, 2021). The AWC of the soil was determined using the gravimetric method modified by Schinner et al (1993).…”

Mitigating the effects of changing climate with adaptable cultivars while reducing the input burden of additional selection criteria is becoming a priority, especially as water shortage is limiting soybean production in Europe. To evaluate the functionality of the photosynthetic apparatus in drought, chlorophyll a (Chl a) fluorescence was measured in 16 elite soybean lines in drought and conditions with sufficient water supply in V2 (second node), R1 (beginning bloom), R4 (full pod), R5 (beginning seed) and R6 (full seed) stages. Developmental stage was a significant source of variation for all parameters, and PI total was chosen as the most sensitive parameter in detecting the average drought effect. Genotypes G5, G9, and G10 had superior overall functioning of the photosynthetic apparatus in drought, while the photosynthetic apparatus of G12 and G16 was the least functional. The drought effect was determined to be the most relevant in R1, R4 and R6. G14 had highest PI total in drought conditions in R1 and R4, while G9 had the highest drought-stressed PI total in R6. G7 had the lowest drought-stressed PI total in R1, G4 and G6 had the lowest in R4, and G8 had the lowest in R6. PI total proved useful in breeding for abiotic stress tolerance, especially for excluding the material with the poorest photosynthetic apparatus function, which increases the efficiency of the selection process when a large number of genotypes needs to be screened. However, genotypes with superior photosynthetic apparatus functioning should be further tested in yield trials to confirm their drought tolerance and value for use in drought conditions.

“…The climate is a temperate continental climate (Cfwbx climate class), with a mean annual air temperature of 12 • C and a mean annual precipitation of 650 mm [60]. The soil at the research site is classified as anthropogenic eutric cambisol (WRB) with a silty clay loamy texture; its main physical and chemical properties are presented in Table 1 [61]. Three irrigation rates (a1 = rainfed, a2 = 60-100% of FC, and a3 = 80-100% FC), three N fertilizers rates (b1 = 0 kg N ha −1 , b2 = 100 kg N ha −1 , and b3 = 200 kg N ha −1 ), and four maize hybrids (c1 = OSSK596, c2 = OSSK617, c3 = OSSK602, and c4 = OSSK552) were arranged as split-split plots in a randomized complete block design with three replications.…”

Extreme Weather Events Affect Agronomic Practices and Their Environmental Impact in Maize Cultivation

Sustainable and profitable crop production has become a challenge due to frequent weather extremes, where unstable crop yields are often followed by the negative impacts of agronomic practices on the environment, i.e., nitrate leaching in irrigated and nitrogen (N)-fertilized crop production. To study this issue, a three-year field study was conducted during quite different growing seasons in terms of weather conditions, i.e., extremely wet, extremely dry, and average years. Over three consecutive years, the irrigation and N fertilizers rates were tested for their effect on grain yield and composition, i.e., protein, starch, and oil content of the maize hybrids; soil N level (%); and nitrate leaching. The results showed that the impact of the tested factors and their significance was year- or weather-condition-dependent. The grain yield result stood out during the extremely wet year, where the irrigation rate reduced the grain yield by 7.6% due to the stress caused by the excessive amount of water. In the remainder of the study, the irrigation rate expectedly increased the grain yield by 13.9% (a2) and 20.8% (a3) in the extremely dry year and 22.7% (a2) and 39.5% (a3) during the average year. Regardless of the weather conditions, the N fertilizer rate increased the grain yield and protein content. The soil N level showed a typical pattern, where the maximum levels were at the beginning of the study period and were higher as the N fertilizer rate was increased. Significant variations in the soil N level were found between weather conditions (r = −0.719) and N fertilizer rate (r = 0.401). Nitrate leaching losses were expectedly found for irrigation and N fertilizer treatments with the highest rates (a3b3 = 79.8 mg NO3− L).

“…Es precisamente el juego de escalas lo que, hasta el día de hoy, ha permitido ajustar el diagnóstico de lo que ocurre en una explotación agrícola. Sin embargo, con la mejora en los sistemas de teledetección, puede bastar una única escala para ser capaces de dilucidar parámetros básicos como la heterogeneidad del cultivo, detectar problemas de manera precoz o determinar sus posibles necesidades hídricas (Haghverdi et al, 2019;Maneta et al, 2020;Marković et al, 2021). No obstante, otras escalas no son descartables y son de interés para este tipo de estudios como completar con información de sensores instalados en suelo o con UAVs que recogen datos complementarios muy ajustados a puntos concretos de las fincas, cuando sea necesario (Capstaff et al, 2021).…”

Bajo el lema "TIG al servicio de los ODS", con el XIX Congreso de Tecnologías de la Información Geográfica se ha querido contribuir a la consecución de los ODS 2030, evidenciando la potencialidad de las geotecnologías e identificando los objetivos y las metas a los que colabora la actividad de la comunidad TIG para transformar el contexto económico, social y ambiental hacia un futuro más sostenible en todas las escalas, a nivel global, regional y local. Las TIG ofrecen herramientas de representación, análisis, integración, comprensión, proyección y modelado de la realidad espacial o geográfica. Las TIG, al igual que todas las partes interesadas, están llamadas a contribuir a la consecución de la nueva Agenda y a colaborar en el proceso de seguimiento de los progresos conseguidos en el cumplimiento de los Objetivos de Desarrollo Sostenible (ODS) y las metas, aportando información y sistematizando indicadores transversales para su evaluación. La publicación incluye las contribuciones científicas presentadas en el Congreso, celebrado en Zaragoza entre los días 12 y 14 de septiembre de 2022.
