Abstract Biodiversity loss, an important consequence of agricultural intensification, can lead to reductions in agroecosystem functions and services. Increasing crop diversity through rotation may alleviate these negative consequences by restoring positive aboveground–belowground interactions. Positive impacts aboveground biodiversity on belowground communities processes have primarily been observed natural systems. Here, we test for the effects increased agroecosystem, where plant is over...
Despite decades of research progress, ecologists are still debating which pools and fluxes provide nitrogen (N) to plants soil microbes across different ecosystems. Depolymerization organic N is recognized as the rate-limiting step in production bioavailable N, it generally assumed that detrital main source. However, many mineral soils, polymers constitute a minor fraction total N. The majority associated with clay-sized particles where physicochemical interactions may limit accessibility...
Abstract Microplastic pollution is a topic of increasing concern for the world's oceans, freshwaters and, most recently, soils. Microplastics have been found in soils across globe. Like other anthropogenic pollutants, they can negatively affect range soil organisms through several mechanisms, though often dependent on particle size, shape and polymer type. However, microplastics are unique among pollutants due to diversity ways which may themselves be able their occurrence distribution...
Abstract Annual row cropping systems converted to perennial bioenergy crops tend accrue soil C, likely a function of increased root production and decreased frequency tillage; however, very little is known about the mechanisms governing accrual stability this additional C. To address uncertainty, we assessed formation aggregates organic C ( SOC ) pools under switchgrass, giant miscanthus , native grass mix continuous corn treatments in Michigan Wisconsin soils differing both texture...
The North Central Education and Research Activity Committee (NCERA-59) was formed in 1952 to address how soil organic matter formation management practices affect structure productivity. It is this capacity that we comment on the science supporting quality associated health assessment for agricultural lands with goal of hastening progress important field. Even though suite indicators being applied by U.S. efforts closely mirrors 'minimum data set' developed recommended mid-1990s, question...
Abstract Agricultural crop rotations have been shown to increase soil carbon (C), nitrogen (N), and microbial biomass. The mechanisms behind these increases remain unclear, but may be linked the diversity of residue inputs organic matter ( SOM ). We used a mixture incubation examine how variation in long‐term plant communities agroecosystems influences decomposition mixtures, thus providing comparison effects diversification on long term (via rotation) short mixtures). Three ranging from two...
To fully understand microplastics' impact on soil ecosystems, one must recognize organisms as not just passively enduring their negative effects, but potentially contributing to formation, distribution, and dynamics in soil. We investigated the ability of four invertebrates, cricket Acheta domesticus L. (Orthoptera: Gryllidae), isopod Oniscus asellus (Isopoda: Oniscidae), larvae beetle Zophobas morio Fabricius (Coleoptera: Tenebrionidae), snail Cornu aspersum Müller (Stylommatophora:...
Abstract Bioenergy production often focuses on the aboveground feedstock for conversion to fuel and other materials. However, belowground component is crucial soil carbon sequestration, greenhouse gas fluxes, ecosystem function. Roots maximize marginal lands by acquiring resources mediating processes through interactions with microbial community. This world challenging observe quantify; however, there are unprecedented opportunities using current methodologies bring roots, microbes, into...
Crop diversification with grain legumes has been advocated as a means to increase agroecological resilience, diversify livelihoods, boost household nutrition, and enhance soil health fertility in cereal-based cropping systems sub-Saharan Africa around the world. Soil organic carbon (SOC) is primary indicator of there limited data regarding SOC pools legume on smallholder farms where soils are often marginal. In Malawi, range options under investigation, including rotations doubled-up...
