Physical Properties of a Hapludox after Three Decades under Different Soil Management Systems

Revista Brasileira de Ciência do Solo, 2016
Changes in soil physical properties due to different management systems occur slowly, and long-term studies are needed to assess soil quality. The objectives of this study were to evaluate the effects of soil management systems and liming methods on the ...

Biodegradable Wireless Soil Urea Sensor Using Metamaterial Perfect Absorber for Distributed Deployment in Precision Agriculture

Advanced Materials Technologies, EarlyView.
In this study, we propose a biodegradable wireless soil urea sensor for precision agriculture. The sensor's electromagnetic response varies depending on the urea concentration, allowing the measurement of relative soil urea concentrations by analyzing the time‐transient electromagnetic response.

Barley, Soybean and Maize Production using Ridge Tillage, No-Tillage and Conventional Tillage in North-East Italy

Journal of Agricultural Engineering Research, 1995
Abstract Ridge tillage can be considered as an alternative to no-tillage in climates and environments which are not very favourable for the latter. It has been conceived almost exclusively for crops such as maize and soybean and this creates difficulties if small grains are introduced into a rotation based on the ridge tillage system.

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Environmentally-sound adaptable tillage – Solutions from Hungary

, 2008
In the last centuries, the need for tillage was to provide suitable soil conditions for plant growth (crop-focusing tillage). During the last decades, traditional goals of soil tillage have really been improved considering environmental consequences ...

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...
