Crop residues management and nutritional improvement practices [PDF]

open access: yes, 2022
Crop residues are the second most important feed source for livestock next to grazing lands in the crop-livestock mixed production system in Ethiopia. However, their contribution to livestock feed in pastoral and agropastoral areas is insignificant.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Ploughing down harvest residues of preceding crops for the purpose of soybean yield improvement [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2019
Soybean yield depends on the choice of cultivar, soil fertility, cultivation practices, and weather conditions in different years. Ploughing down crop residues increases the content of soil organic matter, and thereby positively affects soil fertility ...

Soil CO2 emission and carbon budget of a wheat/maize annual double-cropped system in response to tillage and residue management in the North China Plain

open access: yesInternational Journal of Agricultural Sustainability, 2017
To investigate the impacts of tillage and crop residue managements on soil CO2 emission and C budget in a wheat (Triticum aestivum L.)/maize (Zea mays L.) double-cropped system in the North China Plain (NCP), a field experiment was conducted consisting ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Exploring the influencing factors of continuous crop residue supply: from the perspective of a sustainable and bioenergy-oriented crop cultivation

open access: yesEnergy, Sustainability and Society, 2020
Background Crop residues are an important raw material for bioenergy. There is, however, obvious seasonality in crop harvests, and thus, a continuous supply of crop residues and its respective influencing factors should be investigated.

Generating cost price for crop residues [PDF]

open access: yesJournal of Central European Agriculture, 2019
Considering growing interest and potential for biomass energy production as an alternative to imported oil and as a mode of reducing environment pollution, there is a demand for calculating the economic justification of using crop residues for increasing
