Biomass Carbon in Harvest Residues of Winter Oilseed Rape Across Fertilizer N Rates: Implications for Carbon Input Estimations in Soil Carbon Models

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Reliable estimation of carbon (C) inputs from above‐ and belowground residues at different yield levels is crucial, as these inputs drive soil organic carbon (SOC) models for C accounting. Aims: This study quantifies C inputs from different components of winter oilseed rape (WOSR) and compares them with estimates from various ...

Wheat straw biochar reduces environmental cadmium bioavailability

open access: yesEnvironment International, 2019
Cadmium contamination in waters and soils can lead to food chain accumulation and ultimately deterioration in human health; means for reducing bioavailable Cd are desperately required, and biochars may play a role. Long-term (240 d) lab incubation experiments were utilized to explain wheat straw-derived biochar effects on Cd sorption and decreasing Cd ...

Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Effects of long-term full straw return on yield and potassium response in wheat-maize rotation

open access: yesJournal of Integrative Agriculture, 2015
The effect of long-term straw return on crop yield, soil potassium (K) content, soil organic matter, and crop response to K from both straw and chemical K fertilizer (K2SO4) were investigated in a fixed site field experiment for winter wheat-summer maize

Preparation of Lignopolyols from Wheat Straw Soda Lignin

open access: yesJournal of Agricultural and Food Chemistry, 2011
Wheat straw soda lignin was modified and characterized by several qualitative and quantitative methods such as (31)P NMR spectroscopy to evaluate its potential as a substitute for polyols in view of polyurethane applications. Chemical modification of the lignin was achieved with propylene oxide to form lignopolyol derivatives.

Concentration and composition of condensed tannins in leaves from fodder trees and shrubs in Pakistan

open access: yesJSFA reports, EarlyView.
Abstract Background The lack of dependable, high‐quality forage and animal feedstuffs in many areas of the world hampers livestock production. In these regions, farmers often rely on native fodder tree and shrub leaves as a forage source for their animals with little or no information available on nutritional factors of these feedstuffs.

Effect of lignins on structure, tensile and thermal properties of polyurethanes films [PDF]

open access: yes, 2012
The organosolv lignins of wheat straw acts as a cross linking macromonomer in PU compositions. The fractionation of lignin and variation of fractions contents in PU composition allow to control the properties of PU films and to obtain the elastomers in ...

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

open access: yesJSFA reports, EarlyView.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...
