Preliminary evaluation of perennial forage legumes for organic farming in Finland [PDF]

open access: yes, 2003
In 1998-2001 fourteen forage legume species were evaluated for their productivity in mixed organic swards. The aim was to find new alternatives for red clover. Medicago falcata produced the highest dry matter yield (about 11 000 kg/ha/year).

Carbon-13 cross-polarization magic-angle spinning nuclear magnetic resonance (CPMAS NMR) for measuring proanthocyanidin content and procyanidin to prodelphinidin ratio in sainfoin (Onobrychis viciifolia) tissues [PDF]

open access: yes, 2018
A procedure based on 13C CPMAS NMR was developed to study procyanidins (PCs) and prodelphinidins (PDs) directly in milled sainfoin plant tissues. Blackcurrant and Tilia samples enabled reference spectra of purified proanthocyanidin (PA) fractions, crude ...

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Dynamics and distribution of weed species in weed associations

open access: yesThe Indian Journal of Agricultural Sciences, 2019
Dynamics of weed density with a natural background of weeds in agrophytocenoses of sainfoin (Onobrychis sativa L.), birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.), pure grown (100%) and in mixtures with cocksfoot (Dactylis ...

Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]

open access: yes, 2004
The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

Bioactive forage and phytotherapy to cure and control endo-parasite diseases in sheep and goat farming systems – a review of current scientific knowledge [PDF]

open access: yes, 2007
Infestation with gastro-intestinal nematodes (GIN) in small ruminants can cause severe economic losses and endanger animal welfare. The development of organic farming systems, the increased public awareness for drug residues in agricultural products and ...

Improving Prediction of Heterotrophic Respiration in Response to Altered Precipitation

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Soil heterotrophic respiration (Rh) is a key process in the global carbon (C) cycle, strongly influenced by interactions between soil temperature and moisture. It is well documented how soil temperature regulates Rh. However, temperature interacts with soil moisture to regulate Rh via dynamic and complex microbial mechanisms, leading to ...
