How to Choose the Best Fertilizer for Horse Pasture

Are you planning on fertilizing the pasture for your horses? Do you fear that something may go wrong? Don’t stress out. We have got your back! As a horse keeper, it is advantageous to dedicate a few acres to grow a pasture. It helps in saving a hefty sum of money. But maintaining the quality of the grass is another challenging yet mandatory duty to fulfill.

Adding fertilizers to the pasture improves the quality of the grass. It makes up for deficiencies of nutrients and, as a result, fulfills your horse’s need for additional nutritional supplements. Good quality pasture makes your horse develop a healthy physique along with fast metabolism etc.

Many horse keepers end up making mistakes while looking for the best fertilizer for the horse pasture. Here are some of the important factors you should consider before choosing the fertilizer:

Soil Sampling of Pasture Soil

As the name suggests, soil sampling is a technique that requires you to analyze the nutrient content of the soil. It helps you understand the requirements and deficiencies of the land so you can add the fertilizers accordingly.

If the pasture soil is nutrient-deficient and lacks essential minerals, the pasture will not yield products up to your expectations. Soil sampling and analysis are vital to growing a healthy and best-quality horse pasture.

Grazing Pattern of Horses

Horses are known to be grazers. They eat little at a time but eat frequently at short time intervals. It results in about 17 to 20 grazing periods per day. Naturally, horses live off a fiber-based diet. So the fertilizer you choose must be enriched in fiber content to meet the horse’s feeding requirements.

To learn whether the added fertilizer plan is suitable for your horse, make sure to observe its grazing pattern. If the horse shows signs of refusal towards eating from the pasture, consider changing the fertilizer plan.

The Right Time of Applying Fertilizer

The timing of applying fertilizer also drastically affects the outcomes. Fertilizers give the best results when they are applied at the right time. Every grass has a different ideal time of fertilizer application. The cool-season grasses including, bluegrass, orchardgrass, and bromegrass, should be fertilized at the start of spring to attain more benefits.

If you accidentally skip applying fertilizers to the grass during early spring, you can add it in late spring. However, it is recommended to fertilize horse pasture in early spring.

Types of Fertilizers (Liquid vs Granular)

Fertilizers can either be in liquid or granular form. When adding fertilizer to the horse pasture, choose liquid ones. It is because they even out the soil pH more efficiently. You can avail them easily from an online or local fertilizer store.

The granular fertilizers are better off as health boosters for horse pasture. Such fertilizers contain a high amount of salts, which can potentially burn and damage the grass. Each pellet holds an unequal amount of nutrients, which results in an imbalanced distribution of nutrients.

Choosing the Right Fertilizer Material

Horse pasture requires fertilizers that are rich in nitrogen contents. However, fertilizers containing phosphorous and potassium are also in use. An ideal fertilizer contains large amounts of nitrogen with balanced amounts of phosphorous and potassium. Such a fertilizer does a great job in providing healthy and nutrition-filled grass for horses.

Experts recommend performing a soil test before adding any fertilizer. It helps you discover everything you are exactly looking for. Careful thinking and tests help reap fruitful outcomes.

  1. Mow the land of pasture and take out weeds from it. It makes the soil look neater and easier to work with.
  2. Apply the fertilizer while following the instructions written at the back of the package.
  3. Avoid adding water to the newly fertilized pasture for at least 24 hours.

FAQs Regarding Best Fertilizer for Horse Pasture

Soil fertility is the main force behind forage yield in horse pastures. However, it is critical to provide the grass with adequate nutrients. That is why you should be careful in picking the fertilizer for your horse’s pasture. Here are some frequently asked questions related to the best fertilizer for horse pasture.

What is the right time to fertilize horse pasture?

Fertilizer use in springtime (April or May) increases summer yield, whereas spraying in summertime (in mid of June) increases autumn yield. It is advised for split doses to divide the entire quantity of fertilizer required into two portions, utilizing half in springtime and the other half in the summertime.

Can I fertilize pasture with horses on it?

Forages with exceptionally high nitrate concentration can cause possible horse health issues. Fertilizer should not be sprayed in horse regions. To avoid horses from mistakenly swallowing the fertilizers, horse entrance to the fertilized field will need to be restricted.
Limit horse entry unless at least a half-inch of rain has occurred or for 23 weeks in the case of no rainfall. If you do, properly clean it up and, if required, wash it. Keep horses away from fertilized pastures until it rains.

Should I mow the horse pasture regularly?

“Mowing” refers to the act of trimming grass. It is the method of cutting grass to a similar level in a pasture or yard. The primary purpose of pasture maintenance is to keep or improve grass quality.
Daily mowing is critical for maintaining safe and productive pastures for horses. Mowing of horse pasture at the height of 4 to 6 inches is an effective approach for controlling many pests, “leveling out” grass growth and encouraging tillering of pasture grass species to strengthen the stem.

How long do you keep a horse off after fertilizing pasture?

The most prevalent causes of nitrate toxicity in horses are polluted groundwater, direct fertilizer intake, or the eating of fodder cultivated in the region of spilled fertilizer. Horses must usually be taken from freshly fertilized pastures and returned after a light rain. It is advisable to avoid grazing for 3 to 4 weeks after spraying nitrogen fertilizer.

Can fertilizer hurt my horse?

Horses can be susceptible to nitrates by the consumption of fertilizer or poisonous forages, as well as through drinking polluted water. Since horses lack a rumen, so they are generally tolerant to nitrate poisoning.
When soil is fertilized, grass stems absorb a large amount of chemical nitrogen, resulting in fast growth. If your horse consumes it in this condition, it may become nitrate poisoned and die. High nitrate consumption reduces the blood’s oxygen-carrying capacity, resulting in stress, higher respiration rate, and breathing trouble.

What fertilizer is safe for horse pastures?

– Fertilize as well as lime your pastures when needed, depending on your soil test results.
– Trimming grass ensures that fresh growth is sensitive and nourishing for horses.
– It is critical to control pests in horse pastures. Mowing the horse pasture at the height of 4 to 6 inches is an effective approach for controlling many pests.
– Enhance the topsoil in your pasture. If you haven’t tested your fields for nutrient concentration during the last 2-3 years, now is an excellent time to do so.

How much fertilizer do I need for Hay?

Cool-season grasses like orchard grass, timothy, and tall fescue have been the most often cultivated plants for hay. Every one of these grass varieties has a high nitrogen (N) fertilizer need. A common suggestion for N fertilizer is 40 lbs of nitrogen per ton for predicted hay production. A soil test helps you determine how much phosphorus to apply; typically, 20-40 lbs per acre can boost legumes production in most hay fields.
