How To Choose The Best Organic Liquid Fertilizer For Vegetables?
One of the most important things to consider what nutrients your soil currently needs.
The best way to know this is by doing a soil test, from which you will get a report showing the nutrients present in your soil. Then, you will know what fertilizer can help.
Before buying any fertilizer, you have to take into account the type of soil you’re using: loam, sand, or clay? While loam seems to be the best type of soil, most people have a combination of the three types, in which sand or clay often makes up a larger part.
Sandy soil drains water well but cannot hold nutrients well. On the other hand, clay sold is rich in nutrients but doesn’t drain well.
The choice of fertilizer must be based on your type of soil to stop the fertilizer from being washed away and prevent calcium deposits due to poor drainage.
What do the numbers mean?
As you browse different organic fertilizers, you will see the percentage of concentration of nutrients on their packaging, including the NPK ratio (Nitrogen, Phosphorous, as well as Potassium).
For instance, in a 6-12-0 formula, the percentage of Nitrogen is 6%, of Phosphorous is 12%, and of Potassium is 0%.
So, you should pay attention to these numbers and indicators to find the suitable product for your vegetables.
