Métodos para quantificação da volatilização de amônia em solo fertilizado na su...

Made available in DSpace on 2022-04-28T18:56:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-01-01; Gaseous N losses from soil are considerable, resulting mostly from ammonia volatilization linked to agricultural activities such as pasture fertilization. The use of simple and accessible measurement methods of such losses is fundamental in the evaluation of the N cycle in agricultural systems. The purp...

In situ 13CO2 pulse labelling of field-grown eucalypt trees revealed the effect...

Made available in DSpace on 2022-04-28T19:03:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-08-11; Potassium (K) is an important limiting factor of tree growth, but little is known of the effects of K supply on the long-distance transport of photosynthetic carbon (C) in the phloem and of the interaction between K fertilization and drought. We pulse-labelled 2-year-old Eucalyptus grandis L. trees grow...
