Rodent repellents at a European Union Plant Protection Product level, an orphan use to consider

Journal of Plant Protection Research, 2020
Repellent usage against rodents is almost not provided anymore. Permission to use many rodent repellent substances under European Union (EU) plant protection regulations has not been renewed in recent years.

Natural Organic Compounds for Application in Organic Farming

Agriculture, 2020
Chemical fertilizers, pesticides, and fungicides are widely used in agriculture to improve crop yields. Most of the compounds used are synthetic, and their overuse causes environmental pollution and human health problems. Currently, several countries are

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

The level of N₂-fixation of different genotypes of winter pea in comparison to spring pea in pure and mixed stands

Journal für Kulturpflanzen, 2011
In contrast to the common spring pea (SP), little is known about the capacity of winter peas (WP) for sym­biotic N2 fixation in pure and mixed stands. Therefore, seven WP genotypes and one semi-leafless SP in pure stands and two mixtures with cereals (25%

Weed suppression and crop yield performance in sole and intercrops of common vetch and spring wheat depending on seed density ratio in organic farming

Journal für Kulturpflanzen, 2020
Common vetch (Vicia sativa L.) can be an alternative grain legume to faba beans, peas, lupins and soy beans due to its high grain protein content. As it is uncommon for grain use, cropping systems need to be developed. Weed infestation is a major problem

Understanding bio‐based polymers: A study of origins, properties, biodegradation and their impact on health and the environment

FEBS Open Bio, EarlyView.
This review provides an overview of bio‐based polymer sources, their unique functional properties and their environmental impact, and addresses their role as sustainable alternatives. It discusses end‐of‐life options, including composting and anaerobic digestion for renewable energy.

Enhancement of Fermentation Performance in the Anaerobic Co-Digestion of Chicken Manure and Corn Straw under Biogas Slurry Reflux via Air Stripping of the Digestate

Agronomy
Ammonium inhibition is a key limiting factor for anaerobic digestion when using chicken manure as the main substrate, especially in a digestion system with biogas slurry reflux. Air stripping is usually used as a recycled biogas slurry treatment. In this

Organic farming: technology transfer (Environmental impact and soil fertility) (OF0405) [PDF]

, 2003
This project covered two separate activities, but both were examples of technology transfer, relating to organic farming: 1. Developing a science-based report, which covered an assessment of the environmental impacts of organic farming. Defra’s Action

The impact of long-term organic farming on soil-derived greenhouse gas emissions

Scientific Reports, 2019
Agricultural practices contribute considerably to emissions of greenhouse gases. So far, knowledge on the impact of organic compared to non-organic farming on soil-derived nitrous oxide (N2O) and methane (CH4) emissions is limited.
