Great atlantic sargassum belt and other areas to compare with the baseline measurements that i established back in the 1980s. and the nitrogen content of the sargassum has gone up by 35%. nitrogen is a limit to its growth and production. so i think part of the cause of this is increasing availability of nitrogen -- >> from what exactly? >> well, it could be from a number of both natural and human sources. >> gotcha: we know in the gulf of mexico, for example, we use stable nitrogen iso taupes to identify the source of that nitrogen and it matches up with the value of the mississippi river nitr...

Jan 28, 2021 The California Department of Food and Agriculture (CDFA) Fertilizer Research and Education Program (FREP) announces $2.18 million in grant funds are being awarded to agricultural organizations and universities as a result of the 2020 cycle of the competitive FREP Grant Program. These grants will fund 11 research projects to improve the efficiency of nitrogen (N) fertilization in California agriculture, reduce the associated environmental impacts, and advance farmers’ understanding and implementation of best management practices (BMPs) for fertilizer applications in farmlands. ...
