Possibilities and limitations of protein supply in organic poultry and pig production. Summary of Results from EEC 2092/91 (Organic) Revision [PDF]
, 2005 One of the main objectives of organic agriculture is to establish a largely closed nutrient cycle within the farm system. To limit the input of nutrients in quantity and quality is relevant both to plant and livestock production.

Long‐term, amplified responses of soil organic carbon to nitrogen addition worldwide
Global Change Biology, 2020 Soil organic carbon (SOC) is the largest carbon sink in terrestrial ecosystems and plays a critical role in mitigating climate change. Increasing reactive nitrogen (N) in ecosystems caused by anthropogenic N input substantially affects SOC dynamics ...

Insights into a long life without cancer: The case of the bowhead whale
Molecular Oncology, EarlyView.Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Participatory cotton breeding for organic and low input farming in Central India [PDF]
, 2012 Up to 80% of world’s organic cotton is produced in India. However, involved producers are facing increased difficulties to find suitable cultivars. Few hybrids selected for high input farming and genetically-modified (GM) cotton, which is explicitly ...

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

How are Organic Farming Inputs Evaluated?
EDIS, 1969 The purpose of this document is not to list organic farming inputs but to explain how these materials are evaluated and where to find current online lists of inputs and regulations. This document is HS966, one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences ...

Molecular Oncology, EarlyView.Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches. Created in BioRender. Wikman, H.

Risk Analysis of Organic Cropping Systems in Minnesota [PDF]
When all strategies received conventional market prices, 4-year cropping sequences had greater net returns than 2-year sequences, and the organic input, 4-year strategy had the highest net return.
