“…Crop Yd decreased after crop replacement; that is, maize Yd was greater than that of soybean, which is consistent with previous findings [39]. The high Yd observed under drip irrigation treatments when compared to those under flood irrigation treatments could be due to the increase in soil nutrients and soil microbial abundance after crop replacement [14].…”

Uneven soil moisture and nutrient distribution before and after intercropping limits apple cropping system productivity in the western Shanxi–Loess Plateau area. To address this issue, a field trial was conducted between 2020 and 2021 to study the effects of different water and fertilizer management practices on soil moisture, nutrients, and root distribution, as well as the overall effectiveness of the apple–maize and apple–soybean intercropping systems during crop replacement. The experiment involved two irrigation methods: drip (D) and flood (M) irrigation. Three irrigation levels included rain-fed without irrigation (W0), and 50% (W1) and 80% (W2) of field capacity (Fc). Three fertilizer treatments included no additional fertilizer application (F0), 375 kg∙hm−2 (F1), and 750 kg∙hm−2 (F2), in addition to a control (CK) without irrigation or fertilization. The soil water content (SWC) decreased after the crop replacement. Additionally, nitrate nitrogen (NN), ammonium nitrogen (AN), and organic matter (OM) content levels in all treatments increased, whereas total phosphorus (TP) content decreased. The soil layer with crop roots moved downward after crop replacement, and partial fertilizer productivity (PFP), irrigation water use efficiency (IWUE), and water use efficiency (WUE) were decreased under both irrigation treatments. Principal component analysis showed that the W2F2 treatment had the highest benefit from crop combination across both irrigation treatments during the crop replacement period. According to our results, to optimize the benefits of apple-crop intercropping, drip irrigation with complete water supply and flood irrigation with incomplete water supply are recommended during crop replacement. In addition, an upper irrigation limit of 80% Fc with 750 kg∙hm−2 fertilization is recommended for optimal water and fertilizer regulation.

“…However, advantages of improved pollination and natural pest control are highly context specific. They depend on a variety of factors including the levels of crop pollination dependency (Klein et al, 2007), landscape structure (Martin et al, 2019) and the level of services already provided by natural landscapes in the area (Goldenberg et al, 2022). Furthermore, the benefits for farm revenues will also be subject to the land ownership configuration of neighbouring fields, complicating general cost–benefit assessments.…”

Cost‐effective strategies to increase biodiversity are a fundamental requirement to reconcile conservation and food production in agricultural landscapes. Key for the implementation of such strategies is an accurate quantification of both their benefits and potential associated trade‐offs. We therefore assessed, in a commercially managed grassland, biodiversity responses to two low‐cost management interventions and their mediating effects on ecosystem services. In a 6‐year experiment, we showed that a one‐time seed bank activation treatment had strong initial impacts on biodiversity, increasing plant richness in year 1 by 61%. Long‐term effects, which were also driven by the second management intervention, the propagation of the keystone species yellow rattle, were weaker but nonetheless substantial. These positive biodiversity responses improved ecosystem multifunctionality through additive positive effects of richness, evenness and phylogenetic distinctiveness on nectar production and structural habitat complexity. In contrast, hay biomass production was negatively affected by both management interventions, resulting in a multilevel trade‐off between biomass production competing with biodiversity conservation and the provisioning of other ecosystem services. Synthesis and applications. In this study, we demonstrate that the maximisation of either biodiversity or biomass production requires largely different land management practices. The evaluation of this trade‐off, however, is strongly dependent on its social, economic and ecological context and requires clearly defined land management priorities for both food production and biodiversity conservation.

“…This practice positively affects the abundance and the diversity of bees, representing a relevant increase in oral resources (Brodschneider and Furthermore, it is important to highlight that the exotic bee species Apis mellifera was a dominant species in all bee-plant interaction networks analyzed, but its presence did not in uence network metrics. However, this species is a generalist, using resources provided by a great variety of plants (Giannini et al 2015c, Giannini et al 2020, and its effect on interaction networks can be indirect, such as a decrease in other bee communities (Garibaldi et al 2021a;Goldenberg et al 2022); and the tness reduction of native bee species (Cosmo et al 2023).…”

Bees’ pollination is essential for ecosystems and ecosystem services, including in agriculture. Thus, agricultural management and environmental changes must not affect bee communities and native plants negatively. This study investigated the impact of management practices and areas of native forest around agricultural areas on bee-plant interaction networks. We carried it out in 12 small farming areas with distinct types of management (organic and conventional) and local landscapes (buffer of 1 km with more than 50% of native vegetation or less than it) in the São Paulo Green Belt Biosphere Reserve, SP, Brazil. Our results show that, regardless of the type of forest around the agricultural area and type of management, the bee-plant interaction networks are similar. We concluded that our studied areas were very similar in terms of cultivation characteristics. Nonetheless, our results suggest that less aggressive agriculture management, such as the maintenance of native plants in agricultural areas and the preservation of native forests contribute positively to bee-plant interaction networks, and consequently reduce the impact of pesticide use.
