Why Should I Fertilize My Garden Using Organic Fertilizer?

Organic fertilizer has numerous benefits for both you and your grass.

The fundamental advantage of employing organic soil is just that it adds organic matter and nutrients to the soil and, as a result, enhances nutrient exchange. There are countless microorganisms in the soil that are an important element of the ecosystem that enjoy eating organic fertilizer.

Once the soil is healthier, it retains moisture better and attracts a higher population density of earthworms. Earthworms are indeed the easiest and most effective way to organically improve drainage and aeration, and their excrement is rich in nutrients that plants like. During the planting season, spray organic fertilizers on lawns 2 or 3 times per year. You shouldn't need to fertilize as regularly because natural grass feed enhances the soil quality, structure, and health. To maintain lawn grass growing, apply organic fertilizers as the weather gets warmer up in the springtime, early summer and early fall.

Amongst the most compelling reasons to use an organic fertilizer is that it has a lengthy shelf-life. Because organic content lasts longer to degrade, these fertilizers might last for months in the soil, especially if there is rain or stormy weather.

Such fertilizers gently enrich the soil at a level that provides the grass with what it requires without over stimulating it. Grass grows evenly and slowly, so you wouldn't have to trim as often as you'd want.

Among the most significant advantages of using organic fertilizers is that they do not produce hazardous chemicals. Because you don't even have to worry about spills or difficult clean-ups, having a large number won't harm your lawn.

Those items are, of course, ideal for turf. They obtain all of the resources they need, with fewer shortages and stronger foundations. When the lawn's vegetation gets stronger, it's unlikely to be infested by insects, and weeds have a harder time sprouting.


Organic and Chemical Lawn Fertilizer: What's the Difference?

Natural creatures with high quantities of nitrogen, potassium, and other micronutrients are used in organic lawn fertilizers. Inorganic components are present in chemical lawn fertilizers, and the nutrients are created by synthetic methods. Because organic fertilizers were once live organisms-plants or animals-using them in planting replenishes the soil's nutrients.

Nitrogen (N), phosphorous (P), and potassium (K) are the key nutrients for all forms of fertilizers, organic and synthetic (K). These three nutrients are all in different ratios based on what the fertilizer is used for. Nitrogen and potassium are two essential minerals for grass growth that is healthful, green, and lively.

According to University of Illinois researchers, the majority of natural grass fertilizers come from animals or plants. Seaweed (kelp), alfalfa, and cottonseed meal are major sources of plant-based fertilizers. Bone meal, poultry manure, and feather meal are all good sources of nutrition when it concerns natural lawn fertilizers derived from animals.

Chemical fertilizers are generally the outcome of the petroleum sector, thus according to study. Synthetic fertilizers may yield quick results than organically grown fertilizers, but they pollute the environment. Useful microorganisms in the soil are frequently killed by these fertilizers, resulting in poor soil and growth quality.


Is Organic Fertilizer Better Than Synthetic Lawn Fertilizer?

Organic lawn fertilizers are beneficial both to the grass as well as the soil. Microorganisms in the soil are stimulated by natural fertilizers, which improve soil structure. Organic fertilizers are gentler than synthetic fertilizers, which cause a quick, rapid growth spurt. They also nourish turf grass bases more efficiently. Organic fertilizers produce longer-lasting results over synthetic fertilizers.

Organic lawn fertilizers provide the following advantages over synthetic chemical fertilizers:

Pros

  • Easy to use -you did not have to worry about over-fertilizing your grass with organic fertilizer or spillage.
  • Nutrients -All nutrients are organic and do not promote mineral salt buildup in turf grass soil, which can be hazardous.
  • Micro-nutrients -In addition to the three major nutrients (NPK), organic fertilizers, unlike synthetic fertilizers, also contain a slew of other nutrients that plants require.
  • Nutrient release rate -the nutrients in organic fertilizers gradually break down in the soil, supplying plants as they require them. Because of the gradual release of nutrients, fewer fertilizer applications are required.
  • Impacts on soil -Organic lawn fertilizers improve soil fertility and support a healthy environment in the soil.
  • Safety -Natural fertilizers are better for lawns because they don't damage the roots. Furthermore, when used to grass, organic lawn fertilizers offer no risk to humans or pets.
  • Environmentally friendly -Runoff and leaching onto adjacent water sources are negligible.

Cons

Organic Fertilizers Have Drawbacks

  • To see results take more time and effort.
  • There may be additional weeds.
  • Grub infestations may be more common in your grass.

Buying guide

What's the Finest Organic Lawn Fertilizer on the Market?

The Andersons Innova Organic Fertilizer is the best natural lawn fertilizer in our opinion. This type of fertilizer is made entirely of soybean seeds and provides phosphorus, potassium, and Nitrogen.

This formula employs a carbon-to-nitrogen ratio of 6:1 to create an optimal environment for the soil's healthy bacteria. Also, there are high quantities of amino acids plus nitrogen that are released slowly for long-term effects.

The implementation is quite easy to use. The low-dust granules are safe for kids and cattle to use near lakes, streams, ponds, and other bodies of water. A 40-pound bag can cover a large area that can be used on both new and old lawns.

Organic Lawn Fertilizer Types

There are normally three varieties of organic lawn fertilizer. Everyone has their unique makeup and adds a variety of mineral nutrients to the soil. The three types are as follows:

  • Plant-based

These types of fertilizers are not as long-lasting as the other sustainable options, but they're typically the finest way of preparing the ground. One of the key advantages of plant-based fertilizers is that they can be quite successful in keeping dry crops on the water.

Molasses-related, legumes, cotton meal, Alfalfa meal, and manure bases are also used in plant-related fertilizers.

  • Animal-based

Bone meal, blood meal, and manure are among the ingredients in these fertilizers. They add a load of nitrogen into the soil, therefore, are ideal for planting at the beginning of the season or when seeding the grass first.

  • Mineral-based

Natural mineral-based fertilizers, such as calcium or Epsom salts, can offer critical nutrients to soil while simultaneously raising the pH level.

This is occasionally necessary for optimal growth, and a nutrient-based natural fertilizer is an excellent way to do it.

Granular vs. liquid

Organic fertilizers, including liquid and granular, function in combination with the soil's natural bacteria. When bacterial and fungi devour the natural elements in the fertilizer, they discharge the micronutrients at a controlled rate and also in a form that is readily available for plants.

The rate at which organic fertilizers are consumed by the soil is the difference between liquid and dry organic fertilizers. Dry, granular formulations decompose slowly, providing the lawn for extended periods. Because of the small particle size and accessible moisture, liquid organic fertilizers function faster. If you need a quick dose of nutrients, liquid fertilizer is the way to go.

Ratio of NPK

Green tint and leafy development are aided by nitrogen (N). Phosphorus (P) promotes the growth of deep roots. Potassium (K) improves vigor and resilience to sickness. These three nutrients are the most important for lawns and crops to become green and lush. Nitrogen is a highly volatile element. The quantity not consumed by the lawn evaporates and must be replaced regularly. Because phosphorus and potassium are found in such huge volumes in the soil, they are not needed in such massive quantities. When contrasted to the levels of P and K in the mix, organic lawn fertilizer provides 2 to 3 times or over N.

On the fertilizer label, look for the ratio of NPK. It displays the proportion of the total mass of each component product contains, usually in the order N-P-K. For example, an item with a ratio of 11-2-2 comprises 11 percent nitrogen, 2% phosphorus, and 2% potassium. Other ingredients, as well as any supplementary nutrients, are included on the label.

Desired Outcome

Following a soil test, it's critical to consider the lawn's condition while choosing a fertilizer. Choose a fertilizer with a medium to a high quantity of N ( 10% or above) with little to no P and K in case the grass is vigorous, with dense leaves and a deep green hue. Apply fertilizer with a lesser N ratio and somewhat more K in late summer and fall, as the lawn enters the dormant season.

Even when all three key nutrients are present, the turf may seem yellow at times. It is a common iron insufficiency symptom. Pick a good lawn fertilizer with added iron for a richer green.

In many regions, phosphorus already is abundant in the soil, and it might be tightly controlled to avoid contamination.

Natural Lawn Care: Using the Organic Weed & Feed

You'll need to integrate two separate items for natural weed and feed: First organic fertilizer and the second is organic weed reducer. Corn gluten meal is a natural weed preventative measure for your grass that prevents weed growth from rooting once they germinate. An organic weed killer isn't the same as an herbicide. Thus, unless you have undesirable plants already in your yard, you'll need to use any of these organic weed killers to get rid of them.

To prevent foxtail, crabgrass, dandelions and other lawn weeds, use organic weed and feed treatments twice a year. Espoma CGP6, which is a Preventer of Organic Weed, is a sample of an organic weed preventer that inhibits new weeds from emerging. Before the weeds have grown, use the products of weed and feed. The optimal time for the application of natural weed control is in the springtime. To keep weeds at bay, use the following concepts as part of your natural lawn care:

Before spraying weed and feed, trim the grass of your lawn to a length of roughly 3" (7.5). Wait two days before applying the weed and feed mixture on dry grass. Make sure the application of natural weed and feed is according to the manufacturer's directions. Other organic lawn care procedures can be used to promote the health of the grass and decrease the number of undesired lawn weeds.

The following are some of the benefits of organic lawn care:

  • Lawns should only be watered when the upper few inches get dry, and they should be properly watered. Weed roots are shallower than grassroots, so keep that in mind. So, for organic lawns, letting the top layer of soil dry before watering infrequently but thoroughly is good weed prevention advice. Before spraying water, wait till the top 6" (15 cm) turf is completely dry.
  • To feed your grass, just use high-quality, natural lawn fertilizers.
  • Every 2 - 3 years, check the soil pH level to ensure it's about 6.5. The optimal growth condition for grass is to keep the lawn moderately acidic. Weeds also grow in soil with a pH of 7.5 or higher.
  • The lawn should be aerated. Aeration aids in the removal of thatch improves drainage and allows the root bases to "breathe" extra oxygen.

FAQs

Is it safe to use organic lawn fertilizers?

As long as conventional and organic fertilizers are used appropriately, they are safe for the lawns as well as the environment. Because the process by which plants absorb the nutrients is the same regardless of whether they originate from organic or inorganic fertilizer, it makes no difference to the grasses which kind of fertilizer is used.

What if my lawn becomes wet due to rain after I fertilize it?

However, heavy rain soon after fertilization may cause the fertilizer to flow off the topsoil or into the bottom layer, where it will be less beneficial to your plants. It's also not a good idea to apply fertilizer to damp grass a day after a heavy rainstorm, because fertilizers can attach to wet grass thus causing harm.

Is it safe to fertilize my grass in the summer?

Can I use a certain amount of organic lawn fertilizer?

Even though organics are usually designated as "non-burning," excess fertilizer is a pollutant. Follow the soil test results as well as the product's label directions.

How do I choose the right fertilizer for my lawn?

Purchase an over-the-counter soil testing kit or submit a soil sample to your town's Cooperative Extension Service for examination before purchasing fertilizer. Use the findings of the soils test to determine how much fertilizer to apply.

Is it too late in October to fertilize my lawn?

Fertilizing your lawn twice in the fall in late August and late October will keep it green for the remainder of the year. Nitrogen levels in Winter Survival should not be too high, as this might cause snow mold disease issues later in the winter and early spring.

In the summertime, how can I fertilize my lawn?

Water your grass a day or twice before the application of fertilizer to prepare it. When average temperatures are colder, apply fertilizer at the start or at the end of that day. Following the fertilizer application, give your lawn a vigorous soaking to assist the fertilizer to penetrate into the soil. But be careful not to overwater!

Conclusion

Using the best organic lawn fertilizer can work wonders for your lawn. These fertilizers act in a different way than chemical fertilizers, and they offer several benefits. To maintain the soil fertile, they require fewer treatments and work for extended amounts of time.
