Abstract Intensive agriculture in Germany is not only highly productive but has also led to detrimental effects the environment. Crop diversification together with new field arrangements considering soil heterogeneities can be an alternative improve resource use efficiency (RUE), ecosystem services (ESS), and biodiversity. Agroecosystem models are tools that help us understand design diversified arrangements. The main goal of this study was review extent which agroecosystem have been used for crop at landscape scale by model requirements purpose. We found several available simulating spatiotemporal scale. For spatial diversification, simplified modelling approaches consider interactions light, water, nutrients, they offer restricted combinations. temporal include major crops (e.g., cereals, legumes, tuber crops). However, parameterization limited marginal carbon nitrogen (N). At scale, decision-making frameworks commonly cropping systems. Within-field rarely considered or studies. Combining static dynamic agroecosystems useful evaluation trade-offs ESS delivery To enhance modeling capabilities simulate systems arrangements, it will necessary representation interactions, inclusion more species options, legacy effects, biodiversity estimations. Newly arrangement requires higher data resolution, generated via remote sensing sensors. propose implementation a framework combines process-based optimized respective experiments testing combined framework.

There is currently a demand to grow more crops in less area as result of urbanization’s reduction agricultural land. As result, soil fertility gradually declining. To maintain fertility, various management methods are used modern times. The conventional tillage method traditional that damages structure, but zero can improve quality. By maintaining structure with no-tillage, biological processes frequently improved and microbial biodiversity increased. This review helps understand the role well cropping systems increasing crop production by fertility. For environmental protection be sustained for future generations, quality must maintained continuous systems. nodulation, nitrogen fixation, community all impacted different methods.

Anthropogenic activities have resulted in land desertification various regions of the world, leading to degradation critical soil characteristics such as organic matter (OM) content, nutrient stock, and prevailing biodiversity. Restoring degraded soils through amendments diversified crop rotations is thus an intrinsic part farming. This review discusses a wide range farming impacts on health productivity by focusing fertilizers diversification. Conventional were considered vital for agricultural production harvest high yields. Nevertheless, they are now deemed environmentally hazardous obstacle sustainable agroecosystems due intensive chemical inputs that damage over time long-lasting impacts. fertilization results depletion, loss microbial diversity, reduction, deterioration physical soil. Conversely, makes use naturally existing resources improve health. Organic biochar, manure, fermented grass soil’s physical, chemical, biological properties promote growth diversity beneficial microorganisms—important cycling stability. They facilitate uptake nutrients, hinder pathogen growth, mitigate heavy metals, decompose xenobiotic substances. Moreover, growing cover crops also major strategy Diversified rotation with combinatorial may yields without any detrimental environment soil, ensuring food production, safety, security. integrated approach contributes minimizing their effects environmental It reducing along enhancing OM, biomass, nitrogen fixation, carbon sequestration.

Intensive food and feed production in sole-cropped, large fields with high fertilizer pesticide inputs to achieve yields, has contributed detrimental environmental impacts. To move towards more sustainable agricultural landscapes, cropping system diversification been suggested as a promising practice for which the use of digital technologies could be potentially beneficial. Understanding impact diversified, newly arranged systems their management requires long-term experimental data at landscape scale practical experiences using are hardly available. Experimental platforms an setup farmers' involvement meet such demands but have not set up many regions nor process designing described systematically. The overall objective this study was describe how platform can co-designed jointly by researchers practitioners understand practices compared current Eastern Brandenburg, Germany.

Abstract Context Intensive agriculture drives insect decline impacting insect-mediated ecosystem services that support production. Crop diversification shows promise in increasing crop productivity and enhancing services, however, the impact on biodiversity conservation, particularly of pollinators, is unclear. Objectives Here, we synthesize mechanisms current evidence base how spatial temporal diversity crops within across agricultural fields can benefit pollinator biodiversity. Methods We focus research highly intensified regions, Western Europe North America, from which know a lot about decline, but use inspiration tropical regions. Results find higher diversity, with sequentially flowering cultivars, intercropping practices, larger coverage crops, for example through integrating cultivation forgotten, novel, woody increases flower resource availability throughout active flight period pollinators. All practices increase landscape heterogeneity, further enhanced by decreasing field sizes. As result, functional connectivity increases, improves accessibility foraging ranges Conclusions Our review highlights potential various measures supporting pollinating insects without taking land out production, as well limitations, including only subset species may benefit. Empirical suggest could landscape-wide studies are needed to properly evaluate true conservation part solution bending curve decline.

In this article we explore the concept and implications of three-dimensional (spatial, temporal, genetic) in-field crop diversification to inform systems redesign towards ecological intensification. We first present a conceptual framework for classifying diversity in arable contexts. then apply analyse two long-term experiments The Netherlands where spatial genetic measures were implemented via strip mixed intercropping with aim increase ecosystem service delivery: incidence spreading rate late blight (Phytophthora infestans) potato (Solanum tubersosum L.), biocontrol control potential wheat (Triticum aestivum L.). case blight, potatoes planted strips had significantly lower disease than monoculture reference across all years, adding cultivar mixing within was more powerful mitigating alone. wheat, supported larger (for but one taxonomic group) diverse epigeic natural enemy populations sole culture years. However, addition species did not further indices compared sole-wheat strips. These results imply that compromises between management complexity enhancement are achievable through cropping, an operable practice current machinery, does require thorough reconfiguration production system. proved useful unpacking experimental outcomes terms diversity-mediated mechanisms, however it requires development before can be used facilitate multi-objective optimization.
