Integrating cover crops (CC) in rotations provides multiple ecological services, but it must be ensured that management does not increase pre-emptive competition with the subsequent crop. This experiment was conducted to study effect of kill date on: (i) CC growth and N content; (ii) chemical composition residues; (iii) soil inorganic potentially mineralizable N; (iv) water content. Treatments were fallow a mixture barley (Hordeum vulgare L.) vetch (Vicia sativa sown October killed on two...
Introducing cover crops in irrigated areas may play a relevant role providing ecosystem services such as erosion control, clean water and mitigation of soil degradation. Our objective was to determine the effect replacing traditional winter fallow crop rotations semi-arid by on organic C N sequestration, aggregate stability, infiltration, nitrate leaching. The study conducted comparing barley (Hordeum vulgare L.) vetch (Vicia sp. over course 10 years, with most variables measured every other...
Remote sensing could improve fertilisation by monitoring crop nitrogen (N) status using non-invasive methods. The main goal of this experiment was to test the ability proximal and airborne sensors identify nutritional N maize. We compared various indices combination select those that provided best estimation. As images were acquired from different platforms (drone airplane) we effect spatial resolution (SR) on calculated. study conducted in a field maize Aranjuez (Madrid, Spain) during 2015....
Cover crops have the potential to be agricultural nitrogen (N) regulators that reduce leaching through soils and then deliver N subsequent cash crops. Yet, regulating in this way has proven difficult because few cover crop species are well-studied excel at either reducing or increasing supply crops, but they fail both simultaneously. We hypothesized mixed stands might balance fixing scavenging capabilities of individual species. tested six monocultures four mixtures for their effects on...
Remote sensing (RS) offers great possibilities to acquire data for early determination of crop performance, which is essential water and nitrogen (N) management. The objective this study was assess the nutritional status different wheat genotypes (Triticum aestivum L.) by means vegetation indices (VIs) derived from ground-level hyperspectral measurements, plant traits retrieved coupling a radiative transfer (RT) model with 3-layer neural network, thermal data. To end, two field experiments...
Abstract. Agronomical and environmental benefits are associated with replacing winter fallow by cover crops (CCs). Yet, the effect of this practice on nitrous oxide (N2O) emissions remains poorly understood. In context, a field experiment was carried out under Mediterranean conditions to evaluate traditional (F) vetch (Vicia sativa L.; V) or barley (Hordeum vulgare B) greenhouse gas (GHG) during intercrop maize (Zea mays L.) cropping period. The fertilized following integrated soil fertility...
Aim of study: This study had a double objective that consisted of: (i) assessing the effects N fertilisation on soil quality under different cropping systems (monocropping vs. double-annual systems) irrigated maize conditions; and (ii) identifying parameters related to respond quickly short-term management changes in Mediterranean systems. Area Zaragoza province, Spain Material methods: The field experiment involved strip plot design with three growing – monoculture (MM), pea-maize (PM),...
ABSTRACT Sustainable land management can play an important role in climate change mitigation by reducing soil organic carbon (SOC) losses or even sequestering C soils. This be achieved through practices that increase inputs to the and/or improve quality of these inputs, thereby facilitating removal atmospheric dioxide (CO 2 ) and storing it as SOC. In this study, we investigated potential increased share legumes crop rotations enhance SOC accrual—defined stocks at a given unit compared...
The termination date is recognized as a key management factor to enhance cover crops for multiple benefits and avoid competition with the following cash crop. However, optimum depends on annual meteorological conditions, climate variability induces uncertainty in decision that needs be taken every year. One of most important crop reducing nitrate leaching, major concern irrigated agricultural systems highly affected by date. This study aimed determine effects their water N balances an...
Adjusting nitrogen (N) fertilization and accounting for the legacy of past N fertilizer application (i.e., residual N) based on remote sensing estimation crop nutritional status may increase resource efficiency promote sustainable management cropping systems. Our main goal was to evaluate potential hyperspectral airborne imagers ground-level sensors identifying rates effect from previous in a maize/wheat rotation. A two-season field trial that provided various combinations response...
SUMMARY The introduction of cover crops in the intercrop period may provide a broad range ecosystem services derived from multiple functions they can perform, such as erosion control, recycling nutrients or forage source. However, achievement these particular agrosystem is not always required at same time to degree. Thus, species selection and definition targeted objectives critical when growing crops. goal current work was describe traits that determine suitability five (barley, rye,...
Abstract Cover crops (CCs) provide ecosystem services to agricultural systems by soil health enhancement. However, the long‐term legacy of CCs on arbuscular mycorrhizal fungi (AMF) and subsequent main crop performance is unclear. The objective this work was assess 8‐year AMF activity several plant parameters during a maize ( Zea mays L.) crop. study conducted in field experiment established 2006 under Mediterranean climate. Winter treatments were fallow two CCs, barley Hordeum vulgare vetch...

The objective this study was optimize remote spectral information for its grain yield (GY), biomass, N concentration (GNC), output assessment, decision making on spring wheat fertilization. Spring (Triticum turgidum L.) field experiments testing two tillage treatments, irrigation levels six...
Abstract Early prediction of crop production by remote sensing (RS) may help to plan the harvest and ensure food security. This study aims improve quantification yield, grain protein concentration (GPC), nitrogen (N) output in winter wheat with RS imagery. Ground-truth traits were measured at flowering a field experiment combining four N two water levels central Spain over 2 years. Hyperspectral thermal airborne images coincident Sentinel-1 Sentinel-2 acquired flowering. A parametric linear...
Nitrogen (N) losses from agricultural systems increase air and water pollution, these are highly correlated with the excessive fertilization. An adjusted N fertilization is then a key factor in increasing fertilizer efficiency, leaf clip sensors can help to improve it. This study (combining five different field experiments Central Spain) tried identify ability of maize status identification yield prediction, comparing two devices (SPAD-502® Dualex®) identifying best protocol for sampling. As...
