Abstract Understanding the diversity and community structure of arbuscular mycorrhizal fungi (AMF) is important for potentially optimizing their role in mining phosphorus (P) agricultural ecosystems. Here, we conduct a comprehensive study to investigate vertical distribution AMF calcareous field temporal maize-roots with fertilizer P application over three-year period. The results showed that soil available-P response fertilization but maize yields did not. Phosphorus had no-significant...
Summary Grassland for livestock production is a major form of land use throughout Europe and its intensive management threatens biodiversity ecosystem functioning in agricultural landscapes. Modest increases to conventional grassland could have considerable positive impacts on the provision services, such as pollination, surrounding habitats. Using field‐scale experiment which seed mixes sward were manipulated, complemented by surveys working farms phytometer experiments, impact diversity...
Summary The N orth W yke F arm P latform was established as a U nited K ingdom national capability for collaborative research, training and knowledge exchange in agro‐environmental sciences. Its remit is to research agricultural productivity ecosystem responses different management practices beef sheep production lowland grasslands. A system based on permanent pasture implemented three 21‐ha farmlets obtain baseline data hydrology, nutrient cycling 2 years. Since then two have been modified...
Soil degradation is a major global problem; to investigate the potential for recovery of soil biota and associated key functions, soils were monitored during early years conversion between permanent grassland, arable cropping bare fallow (maintained by regular tilling). Distinct differences in properties had become apparent 50 after previous conversion.Subplots on previously converted two alternatives, generating 9 treatments. (soil organic carbon, mesofauna, microbial community structure...
Abstract The productivity of permanent swards mixed species composition was compared with that sown Lolium perenne , cv. Melle at five fertilizer‐N rates (0, 150, 300, 450 and 900 kg N ha −1 ) L. perenne/Trifolium repens Grasslands Huia 0 . investigation conducted under two cutting frequencies sixteen sites in England Wales, representing a range grassland environments. Annual total herbage dry matter (DM) production from both reseeded increased successive increments up to Herbage DM the...
The soil food web has been referred to as a ‘black box’, ‘poor man's tropical rainforest’ and an ‘enigma’, due its opacity, diversity the limited insight into feeding specificity. Here we investigate flow of C N through way gain understanding interactions occurring. A bacterium, Pseudomonas lurida , was introduced cores from two different habitats, grassland woodland with same type, enriched 99 atom% in 13 15 N, trace bacterial web. Throughout experiment remained N. Almost all invertebrates...
Abstract Understanding trophic linkages within the soil food web ( SFW ) is hampered by its opacity, diversity, and limited niche adaptation. We need to expand our insight between feeding guilds of fauna not just count biodiversity. The drive nutrient cycling play a pivotal, but little understood role both carbon (C) nitrogen (N) cycles that may be ecosystem dependent. Here, we define structure in two habitats (grassland woodland) on same type test hypothesis land management would alter...
Rapid urbanization brings about drastic changes in land use and soil quality. Glomalin-related protein (GRSP), a sensitive indicator of quality, is possibly secreted by arbuscular mycorrhizal fungi (AMF). Besides, microorganisms enzymatic activities play an irreplaceable role improving quality regulating nutrient circulation. However, little data are available on the interactions between GRSP, microorganisms, during urbanization. Here, we selected built-up area (505 km2) Nanchang, China,...
Abstract 1. Few entomological studies include soil‐dwelling insects in mainstream ecological theory, for example the preference–performance debate. The hypothesis predicts that when insect herbivores have offspring with limited capacity to relocate relation a host plant, there is strong selection pressure adult oviposit on plants will maximise performance. 2. This paper discusses proposition live above ground, but offspring, should be included Twelve relevant were reviewed assess potential...
RATIONALE The spatial variability of soil properties is poorly understood, despite its importance in designing appropriate experimental sampling strategies. As preparation for a farm‐scale agro‐ecosystem services monitoring project, the 'North Wyke Farm Platform', there was need to assess key chemical and physical properties. METHODS field‐scale (total N, total C, organic matter), (bulk density particle size distribution) stable isotope ratios (δ 13 C δ 15 N values) studied using...
