Grass grown for dehydration or for chlorophyll productionU.K.
13.—(1) This regulation applies (without prejudice to regulations 7 and 8) in relation to nitrogen which is spread in any twelve-month period, as manufactured nitrogen fertiliser and as nitrogen available for crop uptake from organic manure, on grass grown to achieve a minimum protein content of 16% once harvested and dried.
(2) The occupier of a holding, acting on the written advice of a FACTS adviser, may (subject to paragraph (3)) spread or permit the spreading of nitrogen in an amount so advised even if it exceeds the amount that would otherwise be permitted for grass under regulation 12.
(3) The total amount of nitrogen which the occupier may spread on any given hectare must not exceed—
(a)700 kg, if the grass is irrigated, or
(b)500 kg, if the grass is not irrigated.
(4) For the purposes of this regulation, the total amount of nitrogen from organic manure must be calculated by reference to the methods described in regulation 14 for establishing available nitrogen.
(5) After acting in reliance on this regulation, the occupier must provide the FACTS adviser with soil analyses from representative autumn soil samples so that the adviser may take the analyses into account when advising for the purposes of paragraph (2) in relation to subsequent years.
(6) In paragraph (5), “representative autumn soil samples” means soil samples taken during the period beginning with 1st September and ending with the following 31st October which provide a representative indication of mineral nitrogen levels in the soil on which grass of the kind described in paragraph (1) is grown, taking into account the number of fields, soil type and terrain.
