Physical Attributes of the Soil and Maize Productivity Under an Intercrop System

Journal of Agricultural Science, 2018
The intensive use of agricultural areas for farming, together with inadequate management, can cause soil degradation and promote a low-quality environment for crops; An intercrop system of maize and forage can therefore be an alternative to existing production systems.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

ORGANIC CARBON AND CARBON STOCK: RELATIONS WITH PHYSICAL INDICATORS AND SOIL AGGREGATION IN AREAS CULTIVATED WITH SUGAR CANE

Tropical and Subtropical Agroecosystems, 2017
Soil organic carbon and carbon stock influence, directly or indirectly, most of soil aggregate stability indicators. The objective of this study was to quantify the production of dry biomass (DB), total organic carbon (TOC) and carbon stock (CStk) in ...

Chemical and physical soil attributes in integrated crop-livestock system under no-tillage

Revista Ciência Agronômica
Although integrated crop-livestock system (ICLS) under no-tillage (NT) is an attractive practice for intensify agricultural production, little regional information is available on the effects of animal grazing and trampling, particularly dairy heifers ...

EFFECTS OF SOIL TILLAGE AND CROP ROTATION SYSTEMS ON SOIL PHYSICAL ATTRIBUTES

, 2007
The objective of this study was to evaluate the effects of soil tillage and crop rotation systems on soil physical attributes. The experiment was conducted for five consecutive years and ten crop seasons in a dystrophic Oxisol in Santo Antônio de Goiás, Goiás State, Brazil, in a completely randomized design with four replications arranged in a 2 x 4 ...

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

Advanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...

Gap assessment in current soil monitoring networks across Europe for measuring soil functions

Environmental Research Letters, 2017
Soil is the most important natural resource for life on Earth after water. Given its fundamental role in sustaining the human population, both the availability and quality of soil must be managed sustainably and protected.

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

Advanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.
