Best Organic Fertilizers

For decades, it was wrongly believed that in order to obtain high crop yields farmers need to use chemical fertilizers. It has now been proven that using organic fertilizers can be just as effective yet much safer for the consumer and the environment.

10 Best Organic Fertilizers that Are Safe For Consumer and Environment

And are free from phosphorous, potassium and nitrogen

Chemical fertilizer is made to have a very high concentration of nitrogen, potassium and phosphorus that is then quickly absorbed by the plant while the leftovers get into the soil through the absorption of water thus poisoning the water supply.

Moreover, chemical fertilizers do not contain any minerals or other beneficial microelements that without the soil gets depleted and future yields will suffer.

Plus, crops, fruits and vegetables after the use of chemical fertilizer will still contain traces of it hence you will then eat that and absorb it into your body.

Furthermore, a lot of fertilizers when used in combination with insecticides and pesticides becomes the perfect formula for poisoning your crops.

On the other side, organic fertilizers will provide your crops with the necessary minerals and other microorganisms needed for healthy and fast growth.

How to choose the right organic fertilizer?

Before you go out shopping for a good organic fertilizer, always test your soil to see what minerals and microelements are missing.

Depending on these results, you can then decide what organic fertilizer will help you the most.

Knowing the existing composition of your soil is vital to picking the best organic fertilizer that will help your plants grow strong and healthy.

Nowadays, there are many soil tests that you can purchase at gardening centres and even big supermarkets plus they are affordable and easy to use.

These tests normally test the soil for nitrogen, phosphorus and potassium levels. However, if you live in a small town where such tests are not available then you could take a sample of your soil to an agro state laboratory as most will offer such soil tests.

Next, you would want to research what exact minerals your plant will need as the requirement will change depending on the type of trees, plants and flowers you are planning on keeping in your garden.

Soil acidity is another very important aspect that you would need to look at because if the acidity is too high then it is very likely that your plants will burn.
