Is Horse Manure Good for Garden?

Have you ever heard or seen someone using horse manure to fertilize their gardens? The chances are fifty-fifty, you might have or you have not. The world is progressing by leaps and bounds, why would one want to go the extra mile to use an old fashioned way of fertilizing the garden.

The use of horse manure was common back in the 19th and early 20th century but the invention, catchy advertisement, and easy availability of chemical fertilizers put it under the shade probably because using horse manure as a fertilizer is a tough job.

Even in 2021, the horse manure is still somewhere helping the gardeners bringing life to the lifeless plants. Before moving ahead, I would love to mention here that once one finds out how beneficial horse manure is for the soil and plants he would find it irreplaceable. I can bet on that.

Horse manure improves the fertility of the soil by providing all the necessary nutrients in an organic less damaging way. The effects of using this rewarding manure last longer than the chemical fertilizers and probably these two are the main reasons why it was so popular among the 90’s gardeners.

Before jumping into discussing in detail, let’s answer the most Googled question, it’s basic but it doesn’t deserve ignorance.

Is Horse Manure Good for Garden? Yes, Horse manure is good, no, even better than commercial made fertilizers. Horse manure gives the soil the nutrients it needs to give birth to a healthier and richer garden.

Nutrients in horse manure

What nutrients horse manure have? The answer to this question depends on what a horse eats in a day. If the horse is consuming hay, grains, and a few vegetables then it wouldn’t be wrong to say that the horse manure contains a remarkable quantity of nitrogen, calcium, magnesium, manganese, zinc, potassium, phosphorus, sodium, and some micronutrients.

According to research by Wiley, It’s a balanced formula, no high phosphorus or potassium content.

Some plants can not bear high potassium or phosphorus content, balanced or nitrogen-rich formulas are the gardeners’ favourite. The horse manure contains a huge amount of nitrogen (that is important for food processing, chlorophyll creation, and overall plant growth) with not-so-high phosphorus and potassium content which is why it was and it still has been an advanced gardener go-to option.

Even a new gardener knows nitrogen, phosphorus, potassium are the main ingredients of chemical fertilizers. Sometimes the chemical fertilizers are just a combination of these three but the horse manure is an all-in-one solution. So, how can it be not enough?

How does horse manure work in garden?

Horse manure works the same way as the chemical and organic fertilizers do. The organic matter is added to the soil and it begins supplying the much-needed nutrients. However, the nutrients supply is a bit slower than the chemical-based fertilizers and it needs as much time as organic fertilizers take to reward the soil.

Use correctly

Using horse manure incorrectly can bring more damage to the plants than anything else as it burns down the entire plant within a matter of days. So, to reap the benefits of horse manure one needs to know how to use or compost it correctly.

  • Choose the well-drained soil spot and throw the horse waste matter there.
  • Keep it covered with a tarp or plastic sheet to not let it get wasted away by rain.
