Minimization of tillage for row crops and their productivity

open access: yesАграрная наука Евро-Северо-Востока, 2016
The experiments were carried out in the southern part of the Rostov region in 2007-2015 on usual heavy loam chernozem. Three methods were used: moulded ploughing on 20-25 cm with plow PN-5-35; unmoulded ploughing on 20-25 cm with unit KAO-2; surface ...

Inverse meta-modelling to estimate soil available water capacity at high spatial resolution across a farm

open access: yes, 2011
Geo-referenced information on crop production that is both spatially- and temporally-dense would be useful for management in precision agriculture (PA). Crop yield monitors provide spatially but not temporally dense information.

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

open access: yesAdvanced Science, EarlyView.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

Soil bulk density and soil depth from on-site observations in the North-Western Kurdistan region, Iraq

open access: yes
Soil information is valuable for many disciplines (e.g. agriculture, geomorphology, geology, archaeology) and can be used to produce maps or statistics on soil productivity.

Subsoil Compaction: A hidden form of Soil Sealing in Europe [PDF]

open access: yes, 2001
There are two definitions of ‘soil sealing’: (I) ‘covering (sealing) the soil surface by impervious materials, e.g. concrete, metal, glass, tarmac and plastic’; and (II) ‘changing the nature of the soil such that it behaves as an impermeable medium, e ...

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

open access: yesAdvanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

SYSTEMS OF SOIL PREPARATION EFFECT ON DENSITY AND MACROPOROSITY OF SOIL

open access: yes, 2007
The study was conducted at the Embrapa Arroz e Feijão, Goiânia-Goiás, Brazil, in a clayey dark red latosol, for four consecutive years (1992-1996). During this period eight soil preparation operations were conducted. The objective of the study was to evaluate the effect of systems of soil preparation on density and macroporosity of soil. The experiment

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

open access: yesAdvanced 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 ...

Corn root length density and root diameter as affected by soil compaction and soil water content

open access: yes, 2007
Negative effects of soil compaction have been recognized as one of the problems restricting the root system and consequently impairing yields, especially in the Southern Coastal Plain of the USA.

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

open access: yesAdvanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.
