Abstract Various studies have established that feedstock choice, pyrolysis temperature, and type influence final biochar physicochemical characteristics. However, overarching analyses of pre-biochar creation choices correlations to characteristics are severely lacking. Thus, the objective this work was help researchers, biochar-stakeholders, practitioners make more well-informed in terms how these three major parameters product. Utilizing approximately 5400 peer-reviewed journal articles...
Agriculture and land use change has significantly increased atmospheric emissions of the non-CO2 green-house gases (GHG) nitrous oxide (N2O) methane (CH4). Since human nutritional bioenergy needs continue to increase, at a shrinking global area for production, novel management strategies are required that reduce GHG footprint per unit yield. Here we review potential biochar N2O CH4 from agricultural practices including mechanisms behind observed effects. Furthermore, investigate alternative...
Urea fertilizer applications to calcareous soils can result in significant nitrous oxide (N2O) and nitric (NO) emissions, predominantly via nitrification rather than denitrification. To address this, we explored several mitigation strategies based on improved urea management a rainfed winter wheat (Triticum aestivum L.) crop during two consecutive cropping seasons with contrasting rainfall quantities distribution. The investigated included the split application of at top dressing, use...
An adequate carbon supply is fundamental for plants to thrive under ammonium stress. In this work, we studied the mechanisms involved in tomato (Solanum lycopersicum L.) response toxicity when grown ambient or elevated CO2 conditions (400 800 p.p.m. CO2). Tomato roots were observed be primary organ dealing with nutrition. We therefore analyzed nitrogen (N) and (C) metabolism roots, integrating physiological transcriptomic regulation. Elevated levels of preferentially stimulated root growth...
Abstract Background The skilful handling of N fertilizer, including source type and its timing, is necessary to obtain maximum profitability in wheat crops terms production quality. Studies on grain yield quality with ammonium as sole have not yet been conducted. aim this study was evaluate the effect management (nitrate vs. ammonium), splitting it into two or three amendments during life cycle, under irrigated conditions . Results This experiment demonstrates that Cezanne plants growing...
Abstract Among strategies suggested to decrease agricultural soil N 2 O losses, the use of nitrification inhibitors such as DMPP (3,4-dimethylpyrazole phosphate) has been proposed. However, efficiency might be affected by amendments, biochar, which shown reduce emissions. This study evaluated synergic effect a woody biochar applied with on A incubation was conducted silt loam and obtained from Pinus taeda at 500 °C. Two rates (0 2% (w/w)) three different nitrogen treatments (unfertilized,...
Predicted reduced precipitation, enhanced evaporative demand and increasing CO2 in the atmosphere will strongly influence wheat production. The association of with arbuscular mycorrhizal fungi (AMF) improves growth under stressful conditions. Our objective was to test inoculation on yield, accumulation macro- micro-nutrients gliadins grains durum (Triticum Desf.) plants grown different concentrations water regimes. main factors experimental design were (inoculated or non-inoculated plants);...
The increase in the atmospheric CO2 concentration is predicted to influence wheat production and grain quality nutritional properties. In present study, durum (Triticum Desf. cv. Sula) was grown under two different (400 versus 700 μmol mol–1) concentrations examine effects on crop yield at phenological stages (from filling maturity). Exposure elevated significantly increased aboveground biomass components. Growth diminished elemental N content as well protein free amino acids, with a typical...
Agricultural sustainability is compromised by nitrogen (N) losses caused soil microbial activity. Nitrous oxide (N2O) a potent greenhouse gas (GHG) produced as consequence of nitrification and denitrification processes in soils. Nitrification inhibitors (NI) 3,4-dimethylpyrazole-succinic acid (DMPSA) are useful tools to reduce these N from fertilization. The objective this work was test the efficiency DMPSA two different tillage management systems, conventional (CT) no-tillage (NT), winter...
This study explores the potential use of frass, larval excrement residue obtained from mealworm rearing, as organic fertilizer for crops. Its high matter content means that its joint application with a biostimulant based on efficient microorganisms, favoring mineralization, is interest. An experiment lettuce plants (Lactuca sativa L.) was conducted two factors and six replicates under greenhouse conditions. The first factor frass amendment at 0%, 1%, 2.5%, 5% peat substrate, second...
This work explores whether the natural abundance of N isotopes technique could be used to understand movement within plant during vegetative and grain filling phases in wheat crop (Triticum aestivum L.) under different fertilizer management strategies. We focus on effect splitting same dose through a third late amendment at flag leaf stage (GS37) humid Mediterranean conditions, where high spring precipitations can guarantee incorporation lately applied soil-plant system an efficient way. The...
The Lluta Valley in Northern Chile is an important agricultural area affected by both salinity and boron (B) toxicity.
PREMISE OF THE STUDY: Abiotic constraints act as selection filters for plant invasion in stressful habitats. Adaptive phenotypic plasticity and transgenerational effects play a major role colonization of heterogeneous habitats when the scale environmental variation is smaller than that gene flow. We investigated how parental salinity conditions influence performance invasive dioecious shrub Baccharis halimifolia , which replaces estuarine communities Europe with monospecific continuous...
Nitrogen fertilization is the most important factor increasing nitrous oxide (N2O) emissions from agriculture, which a powerful greenhouse gas. These are mainly produced by soil microbial processes of nitrification and denitrification, application inhibitors (NIs) together with an ammonium-based fertilizer has been proved as efficient way to decrease them. In this work NIs dimethylpyrazole phosphate (DMPP) succinic acid (DMPSA) were evaluated in temperate grassland under environmental...
Abstract An experiment was carried out to determine how the late application of nitrogen (N) fertilizer affects use pre‐anthesis carbon reserves during grain‐filling period pot‐grown wheat with no water shortage. Increasing doses (equivalent 0, 140, and 180 kg N ha –1 ) were applied, either in two amendments (stages GS20 GS30) or three GS20, GS30, GS37, according Zadoks scale). The management by combining an increased rate able stimulate canopy development, raise photosynthetic capacity...
Abstract The current study focuses on yield and nutritional quality changes of wheat grain over the last 166 years. It is based analyses carried out samples collected between 1850 2016. Samples were obtained from Broadbalk Continuous Wheat Experiment (UK) herbaria 16 different countries around world. Our showed that, together with an increase in carbohydrate content, impoverishment mineral composition protein content occurred. imbalance carbohydrate/protein was specially marked after 1960’s,...
Abstract A pot experiment with wheat plants was carried out to study how late application of nitrogen (N) fertilizer affects the use pre‐anthesis N reserves during grain‐filling period. Increasing doses were applied (0, 40, and 52 mg plant –1 ), either in two amendments (growth stages GS20 GS30, according Zadoks scale) or three (GS20, GS37). The arranged a complete randomized three‐block design 129 per treatment. watered daily, harvested every 2 d between anthesis maturity, separated into...
