These limits are in place to protect water quality from agricultural nitrate pollution. The Herdwatch<strong> Nitrates Calculator<\/strong> helps farmers stay on track by allowing them to adjust factors such as cattle numbers and import\/export slurry to instantly see how these decisions impact your final KG\/N\/HA figure and plan accordingly. By visualising your farm\u2019s nutrient application data and comparing it to the legal limits, you can make informed decisions to <strong>stay compliant with NVZ regulations<\/strong>. In addition, the <strong>decision support tool<\/strong> helps farmers plan their nutrient management with precision, ensuring their <strong>fertiliser use<\/strong> is both cost-effective and environmentally responsible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Nitrates and Phosphates Decision Support Tool<\/strong> offers farmers real-time data and actionable insights on nutrient management. Using the interactive digital map, farmers can visualise their fields and <strong>manage nutrient applications with precision<\/strong>, ensuring they <strong>stay within regulatory limits for NVZs<\/strong>.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-white-color has-vivid-cyan-blue-background-color has-text-color has-background has-link-color has-text-align-center wp-element-button\" href=\"https:\/\/applink2.hwbe.io\/?_branch_match_id=1311632394513163276&amp;utm_medium=marketing&amp;_branch_referrer=H4sIAAAAAAAAA8soKSkottLXz0gtSilPLEnOyEvXSywo0MvJzMvW97DwT3MtMg0yd00CAEc4VekoAAAA%20%20\">Try the Nitrates Calculator<\/a><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What are nitrates?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Nitrates are chemical compounds that are essential for plant growth, acting as a crucial source of nitrogen. In agriculture, they often come from fertilisers and animal manure. However, excessive use or mismanagement of these compounds can lead to environmental issues, such as water pollution and biodiversity loss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Legal requirements \/ rules<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the UK, You can apply <strong>up to 170kg per hectare<\/strong> <strong>of nitrogen in livestock manure<\/strong> (including manure deposited directly by livestock and spreading) on your holding in <strong>each calendar year<\/strong>. This limit is the loading limit and applies as an average across your holding. It\u2019s separate from the field limit of 250kg per hectare from organic manures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>You<\/strong> <strong>must not use more than 250kg of total nitrogen from all organic manures spread in any 12 month period on any single hectare of your land<\/strong>. This limit (the field limit) doesn\u2019t include livestock manures deposited by grazing animals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Farmers are required to keep detailed records of their nitrogen use, which includes the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Livestock numbers<\/strong>: Accurate records of livestock are vital as they determine the nitrogen output from animal waste.<\/li>\n\n\n\n<li><strong>Fertiliser use<\/strong>: Farmers must record the types and amounts of fertilisers applied to their land.<\/li>\n\n\n\n<li><strong>Slurry management<\/strong>: The storage, application, and export of slurry must be tracked to ensure compliance with nitrate regulations.<\/li>\n\n\n\n<li><strong>Crop management<\/strong>: Records of crop types and their nitrogen requirements are also necessary.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Grassland derogation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If at least 80% of your holding is grassland, you can apply for grassland derogation to use a higher limit of <strong>up to 250kg of nitrogen per hectare<\/strong>, if the nitrogen comes from grazing livestock manure, i.e. sheep or cattle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can apply for 2025 grassland derogation, find out more information on your region:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.gov.uk\/guidance\/grassland-derogations-for-livestock-manure-in-nitrate-vulnerable-zones\">In England<\/a>, applications for 2025 derogation close 31<sup>st<\/sup> December 2024.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.gov.scot\/policies\/agriculture-and-the-environment\/nvz\/#:~:text=Grassland%20derogation&amp;text=To%20be%20eligible%20to%20apply,Rural%20Payments%20and%20Inspections%20Directorate\">In Scotland<\/a>, applications for 2025 derogation closed 30<sup>th<\/sup> April 2024.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.daera-ni.gov.uk\/news\/online-system-nutrients-action-programme-nap-derogation-2024-applications-and-submission-2023\">In Northern Ireland<\/a>, applications for 2025 derogation closed March 1<sup>st<\/sup> 2024.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Planning your nitrogen usage:<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You must plan all your applications of nitrogen on each crop in each field (including grass).
