- Abstract
A direct proof of intensification of associative nitrogen-fixation activity and considerable increase of intake of biological nitrogen by the pasture ryegrass plants, when using low doses of ammonium-carbonate compounds (ACC) as compared with ammonium nitrate (AN) has been obtained with the help of labelled nitrogen 15N. The isotope method confirms a possibility of biological nitrogen-fixation intensification in the mentioned culture when using synthetic plant growth regulator of a new generation Triman-1. More efficient use of ACC and AN by plant has been established. more...
