The need for a grass fertilizer for horse pasture

Soil fertility is the driving factor for forage production in horse pastures. Though it is important to supply the grass with proper nutrients, it is equally important to ensure that one does not apply excessive nutrients as it can lead to environmental pollution and the degradation of the soil.

Without certain nutrients, plant productivity can reduce significantly. Some of them include, but are not limited to, Potassium, Nitrogen, and Phosphorous. Most recommendations for Potassium and Phosphorous are based on soil tests and nutrient analysis, which is specific to each pasture. Most soil tests do not measure Nitrogen because of its high mobility in the soil.

Most fertilizers have their nutrient listing given on the package itself as it is required by the law. It is usually given in a code of three numbers. For instance, one product can have it labeled as 10-20-5, which is read as 10% Nitrogen, 20% Phosphorous, and 5% Potassium.

When to use the horse pasture fertilizer

Knowing how to make a good horse pasture has more to do with timing than anything else. The growth pattern of the forage should be taken into account and your application of the best horse pasture fertilizer should match it.

Legumes and grasses such as bromegrass, bluegrass, and orchardgrass are suited for the cooler season and their growth is greatest during spring and fall. For such cases, a split approach is recommended. Applying the fertilizer during early spring will boost summer growth, while application during early summer will boost fall growth. This approach works by splitting the total amount required into two applications – applying one half in early spring, and another half in early summer.

How to spread the fertilizer

One can use a broadcast spreader to spread granular fertilizers. On small pastures, spreaders pulled by tractors or walk-behind spreaders work just fine. It is best to fertilize before some light rain as it helps dissolve the fertilizer and move it to the roots of the grass. Avoid spreading fertilizers in areas of standing water, ponds, lakes, or streams.

Will fertilizer hurt horses?

Though most organic fertilizers are quite safe and won’t hurt your horses, the same cannot be said about the other different types of fertilizers especially the ones that are chemical-based and synthetic in nature. Once applied, ensure that you restrict your horses from accessing fertilized pasture and prevent them from accidentally consuming the fertilizer.

It is best to restrict horses accessing the fertilized pasture until at least half an inch of rainfall has occurred. In the absence of rainfall, wait for at least two to three weeks or until there is no visible fertilizer on the surface of the soil. Once the fertilizer has seeped into the deeper soil layers, you can let your horses have access to the pasture again.
