Fel rhan o'r pecyn hwn o fesurau, ac mewn ymateb i bryderon penodol am barodrwydd y sector i weithredu mesurau rheoli ar faint o nitrogen o dail da byw sydd i'w ddefnyddio ar y tir, ym mis Tachwedd 2022, cyhoeddais ymgynghoriad ar gymorth a thystiolaeth ar gyfer cynigion ar gyfer cynllun trwydded â therfyn amser.  Byddai'r cynllun arfaethedig yn galluogi busnesau fferm i wneud cais am drwydded ar gyfer defnyddio lefel flynyddol uwch o nitrogen hyd at 250kg/ha, yn amodol ar angen cnydau a mesurau ychwanegol o ran diogelu'r amgylchedd, tan 2025.
As part of this package of measures, and in response to particular concerns about the sector’s readiness for implementation of controls on the amount of nitrogen to be applied to the land from livestock manures, in November 2022, I issued a consultation on support and evidence for proposals for a time-limited licence scheme.  The proposed scheme would enable farm businesses to apply for a licence for a higher annual nitrogen application of up to 250kg/ha, subject to crop need and additional environmental protection measures, until 2025.
