Are Blood and Bone Meals Good for Your Lawn?

Any animal remains like bones and blood contain a lot of nutrients that would decay into the ground.  Hence, if these remains are ground into what is referred to as a meal, for them to be stored, then they can be beneficial to your lawn. They improve the nutrient availability of the soil which only a few organic substances do. 

Blood meal is also very rich in sodium, potassium, and phosphorus, the three most important macronutrients for plants. Although nitrogen seems to have the largest share of the ratio, others are included in smaller quantities too. 

Moreover, apart from adding nutrients to your plants, blood meal can also deter pests. Pests are repelled when they come across soils or plants with a heavy portion of blood and bone meal.

Blood meal is great for the soil. However, applying too much blood meal can have a detrimental effect on the soil. Blood meal can chase away pests such as rodents that would find their way into your garden to feed on crops.

Overuse of blood meal in the soil can attract crickets that can totally destroy plants and grasses. Blood meal contains macro nutrients with nitrogen taking the highest percentage.

Nitrogen is beneficial to plants but if you apply too much blood meal, then you might introduce too much nitrogen to the soil. When nitrogen is too much in the soil, it can result in stunted growth for your grass. 

Additionally, if your house has pets such as dogs around, excess blood meal on the soil can cause a strong blood smell that would attract this carnivore.

Even some people are naturally allergic to the smell of blood and excessive blood meal additive can affect them too. Besides, it is even more expensive to use too much blood meal as they can be pricey.

Which Is Better, Bone Meal or Blood Meal?

A bone meal fertilizer helps plants grow. It contains phosphorus and calcium, which are both important nutrients for plants. The crushed bones of animals are added to soil as a way to provide these nutrients to the plant roots without having to use synthetic fertilizers.

Bone meal is made by crushing animal bones into small pieces, then heating until they turn into powder form. The bone meal can then be mixed with soil or potting mix before it's used as a fertilizer in the garden or on crops like corn and soybeans.

It is important to note that there are some differences between bone meal and blood meal. Bone meal is very rich in phosphorus and still contains NPK just like blood meal, but nitrogen is more sufficient in blood meals.

You need to test your soil first to know which of the elements is deficient in the soil before choosing which to use. An issue with phosphorus means you should use bone meal while an issue with nitrogen means you should use blood meal. 

Is Blood Meal a Good Source of Nitrogen?

Blood meal has been used for decades as an organic fertilizer. Today, it is also used as a food supplement for livestock. It is a high nitrogen fertilizer that can be used to grow vegetables. This type of fertilizer is usually made from animal blood. It is a great way to add nitrogen, which vegetables need to grow.

Vegetables need high nitrogen levels in order for them to grow properly. Plants that need a high amount of nitrogen to grow are those that need blood and bone meal mostly. 

Examples of these plants include tomatoes, cabbage, and most outdoor vegetables. Cabbage, brussel sprouts, and lettuce are all vegetables that can benefit from the use of blood meal as a fertilizer.

Blood meal can be applied to vegetables in two ways: as a foliar spray or as a soil drenching. A foliar spray will last longer than when applied to the soil, but both methods work well. If there are other ways to get nitrogen organically such as from leguminous plants, then you should do that.
