Things to Consider Before Buying Fertilizers for Horse Pasture

As a horse keeper, it can be a bit heavy on your pockets to keep horses and buy them healthy yet quality food. You prefer having your pasture field to avoid the hustle and provide freedom to your animal.

To ensure the quality growth of the field, fertilizer is the key ingredient that improves soil fertility and provides all the essential nutrients. Here is the list of factors that you should consider before buying fertilizers for horse pasture:

NPK Proportion

NPK plays a key role in plant nutrition. In NPK: N stands for Nitrogen, P stands for Phosphorus, and K stands for potassium. Each of these ‘Big 3’ primary nutrient holds a vital role in fertilizers. If your product says 16-4-8 NPK, then it has 16% Nitrogen, 5% Phosphorus, and 8% Potassium. Make sure that it contains a high amount of nitrogen with a balanced ratio of Phosphorus and Potassium.


Nitrogen is the most vital nutrient, and plants can absorb nitrogen more than any other element. It ensures the healthy growth of plants and gives vibrant color.

Nitrogen is a key ingredient in the formation of a protein that makes up the tissues. That’s why the plants that lack nitrogen turn yellow and begin to die.


Another essential nutrient is phosphorus which harvests the sun’s energy and uses it in plant growth. It helps the plant to grow normally.


It strengthens plants’ immunity to diseases and improves overall growth. But too much potassium can cause nitrogen deficiency in plants.

Right Time for Fertilizer Application

To make sure that the nutrients are available for plants when they need them, it is necessary to apply fertilizer at the right time. Fertilizer is most effective when plants are around the time where they begin to grow actively. Some fertilizer manufacturers suggest their timings or can be applied when there is a deficiency. However, the best time of the year to apply fertilizer is early spring.

Soil Sampling

If the soil of your pasture field lacks essential nutrients, then it may not yield the best results. Soil sampling is a technique to test the present nutrients in the soil. It helps you know the requirements or deficiencies in the soil so you can purchase the fertilizer according to it.

Method to Apply Fertilizer

Proper application of fertilizer is also essential to receive the best results. The following is the recommended method:
