By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, Volume 45, Issue 4, July/August 2026.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Establishment and Yield of Overseeded Black Oat in a Silvopastoral System: Effects of Tree‐Induced Changes in Microclimatic and Soil Conditions

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Tree integration into pasture systems modifies microclimatic and edaphic conditions that can influence forage dynamics, especially during the establishment of overseeding annual cool‐season forage species in subtropical regions. This study evaluated the agronomic performance of black oat (Avena strigosa), overseeded into a warm‐season ...
