Description and prediction of copper contents in soils using different modeling approaches - Results of long-term monitoring of soils of northern Germany
(2022-10-03)
Background: Different regression approaches may be useful to predict dynamics of copper (Cu), an essential element for plants and microorganisms that becomes toxic at increased contents, in soils. //
Aim: Our objective was to explore the usefulness of mixed-effects modeling and rule-based models for a description and prediction of Cu contents in aqua regia (CuAR) in surface soils using site, pH, soil organic carbon (SOC), and the cation exchange capacity (CEC) as predictors. //
Methods: Three sites in northern ...

Take it or leave it? Investigating the ambivalence and willingness to pay for suboptimal fruits and vegetables among organic consumers in Germany
(2022-10-06)
Organic fruits and vegetables are often visually “suboptimal” because organic farming uses neither pesticides nor synthetic fertilisers to improve the cosmetic appearance of the produce. Despite the organic sector's natural and sustainable image, such foods often never reach the market or are left on the shelf, greatly increasing food waste. The current work hypothesised that an important factor in the rejection of suboptimal food is consumers' experience of ambivalence regarding these products. Data were collected ...

Orchard meadows: consumer perception and communication of a traditional agroforestry system in Germany
(2023-03-23)
Europe has a large variety of historic cultural agroforestry systems which provide numerous ecosystem services. Traditional agroforestry landscapes are characterized by a high level of biodiversity, but they lack an economic basis due to considerable time and financial effort required for cultivation, maintenance, and harvesting. Orchard meadows (OM) are a typical example for agroforestry systems. They combine large fruit trees with undercropping or livestock raising. This study investigates consumer knowledge and ...

Peanut monoculture-induced decline in fertility of Andosols in Nicaragua
(2022-08-23)
Background: Andosols are generally characterized by strong resilience to degradation and high soil fertility. This may decline during long-term peanut (Arachis hypogea) monoculture, as indicated by soil chemical and biological properties. Aims: The study investigated the monoculture-induced changes in soil chemical environment as driver for the decline in soil fertility. Methods: In this on-farm study, soils from seven sites cropped with peanut monoculture for different periods between 1 and 20 years were analyzed ...

The efficacy of spatio-temporal predictors in forecasting the risk of Cydia nigricana infestation
(2024-03-15)
The ability to estimate the risk of pest infestation can help farmers to reduce pesticide application and provide guidance that would result in better management decisions. This study tested whether different combinations of spatial and temporal risk factors may be used to predict the damage potential of pea moth, Cydia nigricana Fabricius (Lepidoptera: Tortricidae), a major pest in field pea (Pisum sativum L., Fabaceae). Over four consecutive years, the abundance of pea moth was monitored by placing pheromone traps ...

Yield stability of silage maize double cropping systems across nine German environments
(2023-10-19)
Introduction: Yield and its stability are both vital characteristics to evaluate the viability of cropping systems. However, the current frames of field research hardly allow an accurate evaluation of short-term effect stability. Therefore, over nine German environments (three years and three locations), first crop, maize, total harvested dry biomass yield (DMY), and maize dry matter content (DMC) variability were evaluated through a risk assessment in an organically managed silage maize experiment comprising 18 ...

Perfect apples or sustainable production?—Consumer perspectives from Germany
(2023-08-23)
In recent years, environmental problems, such as resource depletion and biodiversity loss, have come to the forefront of society's attention. Consumption of fruits and vegetables from extensive production systems could decrease food loss and increase biodiversity and more sustainable resource use. However, fruits and vegetables from extensive production systems are not always of perfect external quality, and hence, rejected by consumers. To increase acceptance of imperfect fruits, this study aims to better understand ...

Aqueous Leaching Prior to Dewatering Improves the Quality of Solid Fuels from Grasslands
(2018-04-04)
Renewable energies are necessary to reduce greenhouse gas emissions in energy production, and biomass plays a dominant role in the renewable energy sector. Combustion of biomass constitutes an efficient conversion technique, but is hindered by harmful elements which are frequently contained in residual grassland biomass. We investigated the effect of leaching on solid fuel quality with three independent experiments including the following treatments: (1) with or without leaching, (2) with leaching at various water ...

Assessing the Sustainability of EU Timber Consumption Trends: Comparing Consumption Scenarios with a Safe Operating Space Scenario for Global and EU Timber Supply
(2017-12-02)
The growing demand for wood to meet EU renewable energy targets has increasingly come under scrutiny for potentially increasing EU import dependence and inducing land use change abroad, with associated impacts on the climate and biodiversity. This article builds on research accounting for levels of primary timber consumption—e.g., toward forest footprints—and developing reference values for benchmarking sustainability—e.g., toward land use targets—in order to improve systemic monitoring of timber and forest use. ...

Harnessing the Potential of Wheat-Pea Species Mixtures: Evaluation of Multifunctional Performance and Wheat Diversity
(2022-03-25)
Species mixtures and heterogeneous crop populations are two promising approaches for diversified ecological cropping systems with increased resilience and reduced dependency on external inputs. Inter- and intraspecific diversity were evaluated in combination using 15 wheat (Triticum aestivum) entries, including line cultivars and heterogeneous populations (HPs), from central Europe and Hungary and one winter pea cultivar under organic conditions. Monocultures and wheat mixtures were evaluated multi-functionally for ...
