“…So, it was observed that the continuous cropping of strawberry in the same plot with the same management not only affected native bacteria but also fungi. These findings are consistent with reports in which total fungi and the arbuscular mycorrhizal fungi communities were found to be impoverished in species composition upon agricultural intensification, particularly upon a change from crop rotation to monocropping (Sharma et al, 2015). However, this might depend on the crop types used in the rotation and tillage.…”

“…Several studies have indicated that consecutive monocropping can lead to crop yield and soil quality decline and increased disease pressure (Li et al, 2012). This was observed in different crops such as tomato (Seliga and Shattuch, 1995), pomegranate (Sharma et al, 2015), cucumber (Wu and Wang, 2007), potato, peanut (Liu et al, 2015), and recently in a study on soil microbial diversity and activity linked to crop yield and quality in a dryland organic wheat production system (Tautges et al, 2016).…”

The objective of this work was to explore the impacts of intensive strawberry monocropping during five years on the fruit-yield and on the microbial soil activity and composition. Field trials were performed in two plots: P1(a soil with five years of consecutive strawberry cropping), and P2 (a soil with just one year of strawberry cropping). Fruit-yield was quantified; total microorganisms and four functional groups (cellulolytics, nitrogen-fixers, phosphate solubilizers, and siderophores producers) were quantified, isolated and characterized in both plots.Total microbial activity was assessed by the hydrolysis of fluorescein-diacetate and soil respiration methods. As results, in P1, a 51 % decrease in fruit-yield was observed, while in P2 it was closer to the yield obtained in P1 during the first and second year of cultivation. Total microbial number and activity were 23 % and 70 % lower in P1 than in P2 at the end of the cropping, respectively. In general, the quantity of total culturable microorganisms and the functional groups analyzed were significantly higher in P2 than in P1 (p< 0.05).The most prevailing bacteria putatively identified were Cellulosimicrobium cellulans, Paenibacillus sp., Azospirillum brasilense, and Burkholderia sp. According to our results, the intensive cultivation of strawberry for several years in the same field exerted a negative impact on the soil quality, affecting the native microbial population, which might be linked to the fruit yield decline.

“…On the other hand, emerging agro-industrial multi-purpose crops such cardoon ( Cynara cardunculus L.) and hemp ( Cannabis sativa L.) along with well-established crops, mainly smoking tobacco ( Nicotiana tabacum L.) and pomegranate ( Punica granatum L.) have found additional use for oil production in recent years. A common feature of these crops is the relatively low requirement in terms of cultivation inputs [8,9,10]. Cardoon and hemp oils can be used for different purposes such human consumption, biodiesel production and as traditional medicine ingredient [11,12,13].…”

Simple SummaryRecovery and valorization of residues are key factors for agro-industry to progress towards circular-economy models and more sustainable productions. In the vegetable oils industry, large quantities of spent seed cakes are produced downstream of the oil extraction processes, and their use as animal feedstuffs, mainly as protein supplements for ruminants, is a possible valorization strategy. In this study, we analyzed chemical composition and in vitro digestibility of spent cakes from sunflower, pomegranate, cardoon, tobacco and hemp that are multipurpose cultures emerging in Mediterranean area. The results showed that the cakes of tobacco, cardoon and hemp might be interesting alternative protein feeds for ruminants. The valorization of these cakes may potentially improve economic and environmental sustainability of the emerging vegetable-oil production chains.AbstractFifteen oilseed cakes from sunflower, pomegranate, cardoon, tobacco and hemp were characterized with regard to chemical composition, Cornell Net Carbohydrate and Protein System (CNCPS) fractionation, in vitro digestibility of dry matter, neutral detergent fiber, and crude protein. All the cakes presented low moisture, rather variable ether extract contents and medium to high levels of crude protein and neutral detergent fiber. The cakes significantly differed in terms of CNCPS partitioning and in vitro digestibility. Tobacco and hemp cakes presented high contents of slow degradable fractions of crude protein and carbohydrate joined to good post-ruminal protein digestibility. Cardoon cakes presented the highest rumen protein degradability. Based on crude protein content and intestinal digestibility of rumen undegraded protein, cakes of tobacco and hemp showed the better potential as alternative protein supplements for ruminants, while pomegranate appears to be the least suitable for ruminant feeding.

“…CLM5 is the only land surface model to date that includes time-varying spatial distributions of major crop types and their management (Lombardozzi et al, 2020). Despite these improvements over earlier versions of CLM, the few studies that evaluated CLM5 at point and regional scales suggest inaccurate phenology and crop yield estimates for specific crops (Chen et al, 2018;Sheng et al, 2018). In summary, current crop modules in LSMs are limited by their ability to represent many different crop types and important management practices such as cover cropping and flexible fertilizer application types and amounts.…”

Abstract. The incorporation of a comprehensive crop module in land surface models offers the possibility to study the effect of agricultural land use and land management changes on the terrestrial water, energy, and biogeochemical cycles. It may help to improve the simulation of biogeophysical and biogeochemical processes on regional and global scales in the framework of climate and land use change. In this study, the performance of the crop module of the Community Land Model version 5 (CLM5) was evaluated at point scale with site-specific field data focusing on the simulation of seasonal and inter-annual variations in crop growth, planting and harvesting cycles, and crop yields, as well as water, energy, and carbon fluxes. In order to better represent agricultural sites, the model was modified by (1) implementing the winter wheat subroutines following Lu et al. (2017) in CLM5; (2) implementing plant-specific parameters for sugar beet, potatoes, and winter wheat, thereby adding the two crop functional types (CFTs) for sugar beet and potatoes to the list of actively managed crops in CLM5; and (3) introducing a cover-cropping subroutine that allows multiple crop types on the same column within 1 year. The latter modification allows the simulation of cropping during winter months before usual cash crop planting begins in spring, which is an agricultural management technique with a long history that is regaining popularity as it reduces erosion and improves soil health and carbon storage and is commonly used in the regions evaluated in this study. We compared simulation results with field data and found that both the new crop-specific parameterization and the winter wheat subroutines led to a significant simulation improvement in terms of energy fluxes (root-mean-square error, RMSE, reduction for latent and sensible heat by up to 57 % and 59 %, respectively), leaf area index (LAI), net ecosystem exchange, and crop yield (up to 87 % improvement in winter wheat yield prediction) compared with default model results. The cover-cropping subroutine yielded a substantial improvement in representation of field conditions after harvest of the main cash crop (winter season) in terms of LAI magnitudes, seasonal cycle of LAI, and latent heat flux (reduction of wintertime RMSE for latent heat flux by 42 %). Our modifications significantly improved model simulations and should therefore be applied in future studies with CLM5 to improve regional yield predictions and to better understand large-scale impacts of agricultural management on carbon, water, and energy fluxes.
