“…Meanwhile, artificial cultivation will also meet the market demand for those plant resources [7]. However, successful artificial cultivation of high-quality plants depends on both good germplasm resources and suitable environmental conditions [8,9]. Accordingly, identifying the suitable environmental habitats for the target plant species as affected by global climate change has great economic and ecological value.…”

Cultivation of woody oil plants in environmentally suitable habitats is a successful ecological solution for oil development and forest management. In this study, we predicted the influences of future climate change on the potentially suitable climatic distribution of an important woody oil plant species (walnut; Juglans regia L.) in China based on given climate change scenarios and the maximum entropy (MaxEnt) model. The MaxEnt model showed that the minimum temperature of the coldest month and annual precipitation were the most important determinant variables limiting the geographical distribution of J. regia. We have found that the current suitable environmental habitat of J. regia is mainly distributed in central and southwestern China. Results of the MaxEnt model showed that global warming in the coming half-century may lead to an increase in the area size of environmentally suitable habitats for J. regia in China, indicating more lands available for artificial cultivation and oil production. However, those suitable habitat gains may be practically inaccessible due to over-harvest and urban development, and effective management strategies are urgently needed to establish those forests. This research will provide theoretical suggestions for the protection, cultivation management, and sustainable utilization of J. regia resources to face the challenge of global climate change.

“…With a protein content in duckweed of approximately 354-361 g kg −1 (Table 4), it is possible to obtain 2-4 t of protein per 1 ha yearly from EFL 0.39% and DS 0.39% ponds, respectively. For comparison, with an average alfalfa yield of approximately 8-15 t DM ha −1 , the protein yield is approximately 2-2.5 t [66][67][68]. The conducted research indicates that duckweed culture may be a promising source of protein.…”

This paper presents the results of an interdisciplinary study aimed at assessing the possibility of using duckweed to purify and recover nutrients from the effluent remaining after struvite precipitation and ammonia stripping from a liquid fraction of anaerobic digestate in a biorefinery located at a Dutch dairy cattle production farm. The nutritional value of duckweed obtained in a biorefinery was assessed as well. Duckweed (Lemna minuta) was cultured on a growth medium with various concentrations of effluent from a biorefinery (EFL) and digested slurry (DS) not subjected to the nutrient recovery process. The study’s results showed that duckweed culture on the media with high contents of DS or EFL was impossible because they both inhibited its growth. After 15 days of culture, the highest duckweed yield was obtained from the ponds with DS or EFL contents in the medium reaching 0.39% (37.8 g fresh matter (FM) and 16.8 g FM per 8500 mL of the growth medium, respectively). The recovery of N by duckweed was approximately 75% and 81%, whereas that of P was approximately 45% and 55% of the growth media with EFL0.39% and DS0.39%, respectively. Duckweed obtained from the biorefinery proved to be a valuable high-protein feedstuff with high contents of α-tocopherol and carotenoids. With a protein content in duckweed approximating 35.4–36.1%, it is possible to obtain 2–4 t of protein per 1 ha from EFL0.39% and DS0.39% ponds, respectively.

“…Moreover, it has been demonstrated that the use of forage legumes in agricultural rotations allows important increases in soil carbon sequestration and reductions in the C footprint (Gattinger et al, 2012;Ma, Liang, Biswas, Morrison and McLaughlin, 2012;Teague et al, 2016). As far as we know, very few studies have simultaneously analyzed in time and space the environmental controls of lucerne growth in rainfed conditions (Bowman, Smith and Brockwell, 2004;Hakl, Fuksa, Konecná, Pacek and Tlustoš, 2014). Thus, there is a lack of information on the factors explaining its growth variability both at temporal and spatial scale.…”

summaryLucerne is one of the most valuable forage species because of its high productivity and nutritional traits. However, the knowledge of spatio-temporal variability and environmental controls of its growth generated from the simultaneous study of several sites and throughout several years is extremely scarce. Five-year biomass data were analyzed from four rain fed sites located across a climatic and edaphic gradient in Argentina. The aims proposed were to characterize annual and seasonal lucerne growth, to analyze environmental controls of spatial and temporal growth, and to compare water use efficiency (WUE) among sites. Annual growth differed significantly among sites, ranging between 7,514 and 14,262 kg DM/ha. This range at the spatial scale was mainly explained by variations in annual rainfall and WUE among sites. Seasonal growth depended on incident radiation and actual evapotranspiration. Interannual variability of lucerne growth was explained by precipitation occurred during the growing season in the driest sites, on sandy soils with less water retention capacity. Knowing the sources of variability of lucerne growth, would allow developing more efficient livestock management due to less uncertainty on the forage production dynamics.Key words: soil properties, water use efficiency, forage production, climate.Druille, M., Deregibus V. y Garbulsky, M. F. , 2017. Controles ambientales del crecimiento de alfalfa (Medicago sativa L.) a lo largo de un gradiente climático y edáfico. Agriscientia 34 (II): 13-23 resumen La alfalfa es una de las especies forrajeras más valoradas por su alta productividad y características nutritivas. Sin embargo, el conocimiento de la variabilidad espacio-temporal y los controles ambientales del crecimiento generado a partir del estudio simultáneo de varios sitios y años es extremadamente escaso. En este trabajo se analizaron cinco años de datos de biomasa de cuatro sitios de secano ubicados a lo largo de un gradiente climático y edáfico en Argentina. Los objetivos propuestos fueron: caracterizar el crecimiento anual y estacional de la alfalfa, analizar los controles ambientales del crecimiento a escala espacial y temporal y comparar la eficiencia en el uso del agua (EUA) entre sitios. El crecimiento anual difirió espacialmente, oscilando entre 7.514 y 14.262 kg MS/ha. Esta variabilidad fue principalmente explicada por variaciones en las precipitaciones anuales y la EUA. El crecimiento estacional dependió de la radiación incidente y la evapotranspiración real. La variabilidad interanual del crecimiento fue explicada por la precipitación ocurrida durante la estación de crecimiento en los sitios secos, con suelos arenosos de baja capacidad de retención hídrica. Conocer las fuentes de variación en el crecimiento de alfalfa permitirá el desarrollo de prácticas de manejo ganadero más eficientes debido a la menor incertidumbre en la dinámica de producción forrajera.Palabras clave: propiedades edáficas, eficiencia en el uso del agua, producción de forraje, clima.
