Hi there, We would like to connect with produce suppliers and retailers that would benefit from an upward of 1 month of extended produce freshness. Please reply below or contact me at raffaella@agrinolinc.com to further discuss. We want to share with you our new technology that extends the shelf life of fruits and vegetables by up to 5x! By absorbing greenhouse gases that cause bacteria to grow ...
As global temperatures increase, is it expected that microbial activity will also increase, resulting in faster plant decomposition and increased CO2 efflux into the atmosphere.5,6Measuring Forest Soil CO2 Efflux Determining soil-surface CO2 efflux can be challenging. ...
EFFECTS OF VARYING COVER CROPS ON SOIL RESPIRATION IN A BRAZILIAN OXISOL A Cover Crop/ Soil Respiration Study in Brazil: Validating gains in soil biology with Solvita CO2 – results after 1 growing season. ...
Solvita is a leading commercial test worldwide for soil CO2 respiration (and compost maturity) and is often in comparisons with newer soil respiration methods vying for market share. ...
Organic fertilizer drum granulator production line Organic fertilizers are rich in nutrients needed for crop growth and can continuously supply crops with them.In addition to mineral nutrients, the decomposition of organic matter in soil produces carbon dioxide, which can be used as the raw material for crop photosynthesis and is conducive to the improvement of crop yield.Providing nutrients is ...
Early or late start of the growing season can determine whether the annual ecosystem CO2 exchange will be a carbon sink or source – for example, carbon sinks are natural environments, such as forests, oceans or soils, viewed in terms of their ability to absorb carbon dioxide from the atmosphere. ...
Residues of E1‐expressing maize may effect ecological services (e.g., C mineralization and biogeochemical cycling) on soils where they occur. Therefore, the activity of residual E1 was investigated using soils amended with bacterial and plant‐solubilized E1 as compared to soil endogenous activity and residual activity from a mesostable cellulase ...
Science base Peat drainage, which is needed for oil palms to grow on peat soil, causes a high release of greenhouse gases (GHG) because the peat will oxidise and disappear as CO2. ...
Recent advances in sensor technology provide a robust capability for continuous measurement of soil gases. The performance of solid-state CO2 sensors (Model GMM220 series, Vaisala, Inc., Helsinki, Finland) was evaluated in laboratory, greenhouse, and irrigated winter wheat (Triticum aestivum L.). ...
We evaluated crop yield, C inputs to the soil, and in situ CO2–C fluxes under no-till and conventional tillage (disk tillage) during the 3- to 6-yr period from the installation of an experiment in an Entic Haplustoll of the Semiarid Pampean Region of Argentina to elucidate the mechanisms responsible for possible management-induced soil organic ...
Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. ...
AbstractForest management is expected to influence soil CO2 efflux (FCO2) as a result of changes in microclimatic conditions, soil properties, and root dynamics. ...
Abstract A major uncertainty in predicting long-term ecosystem C balance is whether stimulation of net primary production will be sustained in future atmospheric CO2 scenarios. Immobilization of nutrients (N in particular) in plant biomass and soil organic matter (SOM) provides negative feedbacks to plant growth and may lead to progressive N limitation (PNL) ...
Soils can be highly variable in terms of CO2 flux values. Even at a seemingly uniform site, the soil CO2 flux might range from 2 μmol/m2/s at one location to over 4 mol/m2/s just a few meters away. ...
INTRODUCTION Long-term automated simultaneous measurements at multiple locations within the same study site are often required to adequately characterize high spatial and temporal variability of the soil CO2 fluxes. The multiplexed LI-8100/8150 is a fully automated system dedicated to making such measurements using up to 16 soil chambers. ...
CO2 diffuses out of the soil in response to the concentration gradient between the soil pores and the chamber head space. ...
Air samples can be collected from the same air stream used to measure soil CO2 flux with the LI-8100 Automated Soil CO2 Flux System, for estimating the flux of trace gas, such as methane (CH4), ammonia (NH3), nitrous oxide (N2O), isotopic species, etc. ...
