SCHEDULE 1A

Enhanced nutrient management requirements
Regulations 4A and 4B

Application of Schedule 1A
1
The following enhanced nutrient management requirements apply to the occupier of a qualifying grassland holding intending during the relevant period to apply to the holding, whether directly by an animal or by spreading, a total amount of nitrogen in grazing livestock manure which exceeds 170 kg multiplied by the area of the holding in hectares.

Interpretation
2
In this Schedule—
- “
soil phosphorus index
” (“
mynegai ffosfforws pridd
”) means a reference to the index number assigned to the soil in accordance with Table 1 of this Schedule, to indicate the level of phosphorus available from the soil;“
soil sampling analysis
” (“
dadansoddiad samplu pridd
”) means analysis of a soil sample carried out by a soil testing laboratory to analyse soils for phosphorus.

Livestock manure to be applied to the holding during relevant period
3
The occupier must ensure that the only livestock manure to be applied to the holding during the relevant period, whether directly by an animal or by spreading, is manure produced by the livestock on the holding.

Soil sampling analysis
4
1
The occupier must, for the purposes of determining the soil phosphorus index for each area of the holding with the same cropping regime, nutrient management regime and soil type, undertake soil sampling analysis of at least every five hectares of the agricultural area of the holding with the same cropping regime, nutrient management regime and soil type.
2
An occupier may rely on the results of previous soil sampling analysis of the agricultural area of the holding with the same cropping regime, nutrient management regime and soil type for the purposes of sub-paragraph (1), provided such sampling analysis was carried out within the period beginning with 1 January 2020 and ending with 31 December 2023.
3
Where phosphorus soil sampling analysis of the agricultural area of the holding with the same cropping regime, nutrient management regime and soil type has not been carried out within the period referred to in sub-paragraph (2), such sampling analysis must be undertaken within the period beginning with 1 January 2024 and ending with 30 March 2024.

Determining the soil phosphorus index
5
The occupier must determine the soil phosphorus index for each area of the holding with the same cropping regime, nutrient management regime and soil type by using the results from the soil sampling analysis under paragraph 4 and the values in the following table.

Table 1 – Phosphorus index
Phosphorus index | Phosphorus (P) mg/L Olsen (P)
0 | 0-9
1 | 10-15
2 | 16-25
3 | 26-45
4 | 46-70
5 | 71-100
6 | 101-140
7 | 141-200
8 | 201-280
9 | Over 280

Planning the spreading of phosphate fertiliser
6
In addition to the production of nitrogen spreading plans under regulation 6 (planning the spreading of nitrogen fertiliser) the occupier must, within the period beginning with 1 January 2024 and ending with 30 March 2024—
a
calculate the optimum amount of phosphate fertiliser (kg) that should be spread on the crop during the relevant period, taking into account the soil phosphorus index, and
b
produce a plan (“enhanced nutrient management plan”) for the spreading of phosphate fertiliser during the relevant period.

Requirements for enhanced nutrient management plans
7
1
The enhanced nutrient management plan for the holding must—
a
include a risk map, produced in accordance with paragraph 11(1), indicating the location of the fields to which the plan relates, and
b
clearly state in relation to any field referred to in the plan the type of fertiliser to be used.
2
The enhanced nutrient management plan must record—
a
the soil phosphorus index for each area of the holding with the same cropping regime, nutrient management regime and soil type,
b
the optimum amount of phosphate fertiliser (kg) that should be spread on the crop, taking into account the soil phosphorus index,
c
the amount of nitrogen (kg) likely to be available for uptake by the crop from any organic manure intended to be spread for crop uptake in the growing season during the relevant period,
d
the amount of phosphate (kg) likely to be supplied to meet the requirement of the crop from any organic manure spread or intended to be spread during the relevant period, calculated in accordance with—
i
tables 1 and 2 (as applicable) of Schedule 1,
ii
sampling and analysis in accordance with Part 2 of Schedule 3, or
iii
technical analyses provided by the supplier,
e
the amount of manufactured nitrogen fertiliser (kg) required (that is, the optimum amount of nitrogen required by the crop less the amount of nitrogen that will be available for crop uptake from any organic manure spread during the relevant period), and
f
the amount of manufactured phosphate fertiliser (kg) required (that is, the optimum amount of phosphate required by the crop less the amount of phosphate supplied for crop uptake from any organic manure spread for the purpose of fertilising the crop during the relevant period).

Total phosphorus spread on a holding during relevant period
8
Irrespective of the figure recorded in the enhanced nutrient management plan in accordance with paragraph 7(2)(b), the occupier must ensure that the total amount of—
a
phosphate from manufactured phosphate fertiliser, and
b
phosphate from organic manure, in the growing season in which it is spread,
does not, during the relevant period, exceed the limits set out in paragraph 9.

Maximum phosphate limits by crop
9
1
Subject to sub-paragraph (2), the total amount of phosphate spread on any crop listed in the first column of any of the tables below must not exceed the figure under the applicable soil phosphorus index number in the same table.

Soil protection measures
23
1
The occupier must protect all soil by ensuring that all land is covered by crops, stubbles, residues or other vegetation at all times, except where establishing such cover would create a significant risk of soil erosion and significant risk of nitrogen and phosphorus getting into surface water.

the stubble of the harvested crop remains in the land, or
b
the land is prepared as a seedbed for a crop or temporary cover crop within 14 days of harvest, beginning with the first day after harvest, and—
i
the crop, or temporary cover crop, is sown within a period of 10 days beginning with the day after final seedbed preparation, or
ii
if sowing within that 10-day period would lead to significant risk of soil erosion, and nitrogen or phosphorus entering a surface water, the crop, or temporary cover crop, is sown as soon as is practicable after the land ceases to be waterlogged.

Spreading organic manure near surface water during relevant period
26
The occupier must ensure that during the relevant period no person spreads organic manure within 15 metres of surface water unless using precision spreading equipment, in which case no person may spread organic manure within 10 metres of surface water.
