Max N and P

thefather

Hi folks. What is the maximum N and P per hectare I can apply as organic compost on non stocked land where two cuts of silage have been taken this year. Its my only holding. I want to stay on the right side of the GAP/Nitrates Regulations. Soil tests indicate adequate K and very low P, index 1. I have tried using the Departments calculator but not sure if I have used correctly, see attached. Any guidance would be appreciated. Thanks.

Max organic N is 170kgs per Ha. P depends on soil samples and what index the soil is.

Thanks for the reply tractorporn. Even though the limit is 170kgs per Ha. The regulations seem to suggest that for a holding where there is no stock/grazing the allowance is higher, but perhaps I am reading it incorrectly.

Yeah that's the bag fertiliser limit, you can't break 170 unless you want to go into derogation
