Degradation of agricultural land and the resulting loss of soil biodiversity and productivity are of great concern. Land-use management practices can be used to ameliorate such degradation. The soil bacterial communities at three separate arable farms in eastern England, with different farm management practices, were investigated by using a polyphasic approach combining traditional soil analyse...
In recent years, an intense debate about the environmental risks posed by neonicotinoids, a group of widely used, neurotoxic insecticides, has been joined. When these systemic compounds are applied to seeds, low concentrations are subsequently found in the nectar and pollen of the crop, which are then collected and consumed by bees. Here we demonstrate that the current focus on exposure to pest...
– Local content policy in Nigeria promotes the development of innovative indigenous technology aimed at contributing to national science and technological development. Consequently, bioremediation agent (Ecorem) was formulated from Nigeria local raw materials as a contribution to enhanced environmental performance in the petroleum sector. As part of evaluating kinetic mechanism of this product,...
We assessed the potential impacts of land-use changes resulting from a change in the current biofuel policy on biodiversity in Europe. We evaluated the possible impact of both arable and woody biofuel crops on changes in distribution of 313 species pertaining to different taxonomic groups. Using species-specific information on habitat suitability as well as land use simulations for three differ...
The change of primary forest areas into arable land involves the transformation of relief and modification of soils. In this study, we hypothesized that relatively flat loess area was largely transformed after the change of land use due to erosion. The modifications in soil pedons and distribution of soil properties were studied after 185 years of arable land use. Structure of pedons and solum ...
Despite a growing body of research linking bioenergy cultivation to changing patterns of biodiversity, there has been remarkably little interest in how bioenergy plantations affect key ecosystem processes underpinning important ecosystem services. In this study, we compare how the processes of predation by ground arthropods and litter decomposition varied between Short Rotation Coppice (SRC) wi...
Predicting outcomes of transgene flow from arable crops requires a system perspective that considers ecological and evolutionary processes within a landscape context. In Europe, the arable weed Raphanus raphanistrum is a potential hybridization partner of oilseed rape, and the two species are ecologically linked through the common herbivores Meligethes spp. Observations in Switzerland show that...
The manipulation of plant and environmental microbiomes is becoming an increasingly popular tool to sustainably increase farm productivity for food and nutrient security (Singh and Trivedi, 2017). There are multiple drivers for the increasing focus on microbiome tools in agriculture, including the need for a substantial increase in food production from shrinking arable lands. For example, an in...
To seek optimal network parameters of Radial Basis Function (RBF) Neural Network and improve the accuracy of this method on estimation of soil property space, this study utilizes genetic algorithm to optimize three network parameters of RBF Neural Network including the number of hidden layer nodes, expansion speed and root-mean-square error. Then, based on optimized RBF Neural Network, spatial ...
In the context of China’s trial fallow policy; the heavy metal pollution of farmland is addressed via field surveys in Hunan Province, where the fallow policy has been implemented, and in Jiangxi Province, where it has not been implemented. We measured and analyzed willingness to accept (WTA) using the contingent valuation method (CVM). The conclusions of this study are as follows: (1) Farmer a...
