Physical, chemical and biological soil attributes in integrated crop-livestock-forestry systems

Agrarian, 2019
Integrated systems have become common in several regions of Brazil and studies on the effects of these systems on soil attributes have intensified. However, there are still doubts about possible negative impacts due to the degradation of the environment due to the use and applied management, such as machine traffic and animal trampling.

Stimulus‐Induced Self‐Reinforcement in Supramolecular Bamboo Plastics toward Mechanical Robustness and Programmable Shapeability

Advanced Science, EarlyView.
A self‐reinforcement strategy is reported for the fabrication of bamboo plastics utilizing ethanol to induce the supramolecular network reconstruction of cellulose and polyacrylamide molecules. These bamboo plastics exhibit high mechanical strength, excellent thermal stability, resistance to low temperatures, and controllable shapeability.

Funções de pedotransferência para estimativa da retenção de água em alguns solos do Rio Grande do Sul Pedotransfer functions to estimate the water retention in some soils of Rio Grande do Sul state, Brazil

Ciência Rural, 2010
As propriedades hidráulicas do solo são determinações consideradas caras e de difícil obtenção. O uso de funções de pedotransferência (FPTs) consiste em uma alternativa para a obtenção dessas informações de forma mais fácil e com menor custo.

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Spatial variability of physical attributes of the soil in amazonian black soil under coffee cultivation

, 2017
A conversão de ecossistemas naturais em sistemas agrícolas provoca alterações significativas nos atributos do solo, associado ao crescente desmatamento na região amazônica influenciando a desestabilidade do ecossistema. Dessa forma, objetivou-se com este estudo avaliar a variabilidade espacial dos atributos físicos do solo em área de terra preta de ...

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...

Farmers' Participation in Messenger‐Based Social Groups And Its Effects on Performance in Irrigated Areas of Kazakhstan and Uzbekistan

Agribusiness, EarlyView.
ABSTRACT The penetration of information and communication technologies (ICTs) in farming communities is increasing the use of smartphone‐based instant messaging apps. Despite this, the reasons behind participation and the impact on farm productivity in developing countries remain unexplored.

Upcycling Spent Lithium Iron Phosphate Battery Into Fe‐CN3P Single Atom Catalyst for Environmental Remediation

Angewandte Chemie, EarlyView.
Electrochemical (EC) advanced oxidation enables near‐complete lithium and iron recovery from spent lithium iron phosphate batteries, while simultaneously transforming leach residues into a high‐performance P, N‐doped single‐atom Fe catalyst. The reconstructed Fe–CN3P catalyst exhibits exceptional peroxymonosulfate (PMS) activation and rapid bisphenol A
