10 Best Organic Lawn Fertilizers and Buying Guide
Growing a healthy lawn requires plenty of effort and time. Fertilizer is one of the important things you need for your lawn. There are plenty of synthetic fertilizers available in the market now.
But the problem with these fertilizers is the toxic salts and chemical build-up that can harm your lawn and soil. This is why soil friendly, renewable, sustainable, and biodegradable organic fertilizers are preferred by many people now.
There are many more benefits in organic fertilizers that ensure your grass and soil grow strong and healthy. In this guide, you will know about the significant considerations regarding use of organic fertilizers and the best organic lawn fertilizer products available now with their pros and cons, so you can make an informed decision.
Why Organic Fertilizers Are Considered The Best For Lawn Growth?
Organic products are advocated by environmentalists and they also have very few or no side effects. Thus, choosing organic over synthetic is always preferable. Furthermore, there are several other benefits you get when it comes to lawn growth:
Organic fertilizers not only release nutrients needed for the soil they also enhance soil structure. They help to increase soil’s capability for holding nutrients and water when they break down.
Since the breakdown of organic fertilizer occurs very slowly, there is no risk of adding excessive amounts of fertilizers that can harm the plants.
The water holding ability enables better moisture level of the soil, which attracts earthworms. Earthworms are effective in improving aeration and proper water drainage. The waste materials secreted by earthworms are nutrient rich, which further help in keeping soil healthy.
Due to slow release of fertilizers, grass grows at a slow and even pace avoiding frequent mowing.
There is no hassle of dangerous chemical spills or clean-ups, which occur with synthetic fertilizer use.
Natural Lawn Fertilizer for Hassle Free Lawns
With organic fertilizers, the grass roots are stronger discouraging growth of weeds. Thicker grass growth prevents spread of weeds as the restricted space prevents their growth. You will be spending less on treating the weeds and save the time spent on applying weed killers on the lawn.
Due to healthy thick and strong grass formation from organic fertilizers, the lawn stays resistant to disease and pests. This is because organic fertilizers provide the immunity needed for the plants to resist illness
The healthy lawns are also resistant to weather fluctuations. Weak grass tends to brown and burn in hot weather. It may also wither and die in drought conditions. With stronger grass, there is less impact of weather fluctuations. Due to stronger roots, more water is absorbed by the grass.
Safe and Environment Friendly Lawns
The absence of harsh synthetic products and chemicals in organic fertilizers makes them perfect for use in lawns. You will not have to worry about the safety of your pets and kids as with synthetic fertilizers where contact with harsh chemicals can cause health hazards. With organic fertilizers, you will not have to be concerned about your children and pets playing on the lawn.
Since fertilizers can enter into surrounding waterways through the soil, they can cause harm to wildlife and humans too. With organic fertilizer, you can ensure that no such chemicals affect water bodies around you. In fact, there are several regions that place strict regulations regarding use of chemicals in fertilizers.
Organic fertilizers are derived from natural sources, which are mostly biodegradable waste. Fish bones, poultry manure, vegetable waste, etc. are used as fertilizers thus turning them into a useful product.
Important Factors to Consider While Using Natural Lawn Fertilizer Products
Although organic and synthetic lawn fertilizers provide similar results there are certain differences present, which include the following:
Ease of Application
Organic fertilizers are available in pellet form, which is easy to apply. Synthetic fertilizers which are made from chemicals are in liquid form mostly. Although the application is easy, over application can lead to brown spots due to burning of lawn.
When you apply fertilizers, you have to be very careful if you are using a synthetic fertilizer, as it causes build-up of nutrients, run off, leaching, improper ratio, and other issues resulting in destruction of your lawn.
While using natural lawn fertilizer brands, although you may see slow results, it will not harm your lawn in any way. And when you look at long term benefits the money spent on organic fertilizer is a good investment.
Organic products do not have measured or specific quantities of nutrients. Furthermore, they do not contain macronutrients. In synthetic fertilizers, specific quantities of important or essential nutrients are present, but do not contain macronutrients. Further these artificial fertilizers can accumulate in soil over the long term and also get washed away during watering or when it rains heavily.
With organic fertilizers, the release of nutrients is slow resulting in less overgrowth and fewer applications. For synthetic fertilizers, growth is rapid and this results in frequent mowing. Also, since the nutrients are released rapidly and run off during watering, more applications are necessary.
Preserve Soil Health
The natural bacteria and microorganisms in organic fertilizer helps in improved soil composition. The organic materials help create a healthy ecosystem required for good plant growth. Synthetic fertilizers on the other hand reduce fertility of soil over long term use.
Synthetic fertilizers are cheaper than their organic counterparts. However, the added expense is justified, as it saves you plenty of effort and time you would otherwise spend on frequent mowing, cleaning up spills and not to mention the loss of fertility to the soil.
Nitrogen, Phosphorus and Potassium (NPK) are considered as important macronutrients needed for plant growth. Other macro nutrients include magnesium, calcium, and sulfur. Micronutrients needed by plants include iron, zinc, manganese, boron, molybdenum, chlorine and nickel.
The macronutrients N, P, and K are considered as important nutrients as they help in optimal growth of plants. Based on the type of soil you have such as peat, clay or sand the amount of nutrients differ. Knowing the NPK content of your soil will help you to add the appropriate amounts needed for lawn growth.
Since NPK is present in low quantities in natural lawn fertilizer products, you may have to consider adding specific NPK supplements. However, adding synthetic fertilizers for their NPK content may actually harm your lawn in the long term due to the change in soil fertility and also produce short term effects such as over application or spills.
With organic fertilizers, the plants receive the nutrients slowly over a prolonged time span. Less application can reduce the cost of the organic fertilizers or you can consider the use of homemade lawn fertilizer. Whichever organic fertilizer you use it remains the best way to ensure a healthy and long-standing lawn.
