Quantification of C and N stocks in grassland topsoils in a Dutch region dominated by dairy farming [PDF]

Estimates on soil organic carbon (SOC) and nitrogen (N) stocks in soils cannot be directly calculated from routine soil analyses, since these often lack measurements on soil bulk density (Bd).

Physical Quality Indicators and Mechanical Behavior of Agricultural Soils of Argentina.

PLoS ONE, 2016
Mollisols of Santa Fe have different tilth and load support capacity. Despite the importance of these attributes to achieve a sustainable crop production, few information is available.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Physical characteristics of soil under different cropping and natural system on the plain of jars, Xieng Khouang province, Laos [PDF]

, 2006
Conservation agriculture and direct seeding mulch-based cropping (DMC) systems greatly modify plant and soil interaction. Plants commonly provide energy that fuels biological processes and either directly or indirectly creates structure within soils ...

Energy in Clod-Size Reduction of Vibratory Tillage [PDF]

, 1969
The objective of mechanical manipulation of the soil (tillage) in production of agricultural crops is to produce soil conditions and environment favorable to crop growth by changing bulk density, soil-aggregate size distribution and other characteristics

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Impact of mechanized harvesting on compaction of sandy and clayey forest soils : results of a meta-analysis [PDF]

, 2012
Nowadays, harvest operations are predominantly performed fully mechanized using heavy tractors or forestry machines. The resulting soil compaction may negatively affect the soil ecosystem.

Tillage effects on soil properties, crop responses and root density of sweet pepper (Capsicum annuum)

Spanish Journal of Agricultural Research, 2021
Aim of study: Soil compaction causes an increase in bulk density, resistance to penetration, low diffusion of oxygen and water in the soil. Tillage is one of the techniques to alleviate compaction.
