Managing Nitrogen

We are focussing on what is probably the most well-known plant nutrient: Nitrogen.

Birdsfoot trefoil, a native nitrogen fixing plant. 

Nitrogen is responsible for lush, green grass growth, and so it is generally best to restrict the amount of nitrogen we apply to horse pastures to avoid the risk of laminitis. Nitrogen can also leach through the soil into rivers and streams, where it causes pollution, if you do decide to apply nitrogen, consider a slow release product to protect both horses and the environment.

The most obvious source of nitrogen for pastures is manure. Where fields are regularly poo-picked, this can deplete nutrients in the soil. Applying well composted manures back to the land can supply a good source of slow-release nitrogen to provide nourishment to our grassland, as well as supplying other major nutrients.

Another way through which our grassland can receive the nitrogen it needs is through nitrogen fixing plants such as clovers and birdsfoot trefoil. These plants are known as legumes and have the unique ability to obtain nitrogen from the air, making it available to plants. This is an extremely sustainable method of feeding our grassland, and also increases the protein content of our grass. Next time you take a walk through the fields, see if you can identify any clover. This tiny powerhouse could be quietly feeding your grass!
