Long-term effects of grazing intensities on soil aggregation and organic matter in a no-tilled integrated soybean-cattle system [PDF]

open access: yes, 2022
Grazing intensity in integrated crop-livestock systems (ICLS) can affect soil aggregation and C stabilization and, consequently, the soil condition and agricultural sustainability.

Long term application of pig manure on the chemical and physical properties of Brazilian Cerrado soil

open access: yesCarbon Management, 2019
Intensive pig farming is an important economic activity and generates a large amount of liquid pig manure as a by-product, which is considered a promising resource for the fertilization of tropical soils, characterized as low natural fertility.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

open access: yesAdvanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Biotic and abiotic binding and bonding mechanisms in soils with long-term differences in management

open access: yes, 2000
During the last decades Denmark has experienced a growing interest in low-input farming systems like organic farming. These systems rely on a high soil fertility to maintain nutrient availability and plant health.

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

open access: yesAdvanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.

Aggregation of ecological indicators for mapping aquatic nature quality : overview of existing methods and case studies

open access: yes, 2010
Indicators for aquatic nature quality are calculated using ecological monitoring data from individual sampling stations. For reporting purposes, these results need to be aggregated and scaled up to higher levels (catchment area, country).

The effect of organic farming on soil physical properties, infiltration and workability [PDF]

open access: yes, 2011
Organically managed land has increased to 4 % of the total area of agricultural land in the UK. Changing land management can impact upon the rural environment (soils, hydrology and biodiversity) and rural community (socio-economics and culture).

Divergent consequences of hydrochar in the plant-soil system: arbuscular mycorrhiza, nodulation, plant growth and soil aggregation effects

open access: yes, 2012
Establishment of a sustainable carbon sink by producing and adding carbonized materials to soils provides a promising way to reduce atmospheric CO2 concentrations and mitigate the progressing climate change.
