... also add nitrogen to the system. Biologically fixed nitrogen in a moderately grazed mixture with bahiagrass normally ranges from the equivalent of 30 to 75 lb/A of nitrogen. Nitrogen fixation by carpon desmodium can be negligible if it is continuously heavily grazed or receives nitrogen fertilization. Carpon adds quality to normal bahiagrass ...
