What is NPK and What Does It Do for Plants?

NPK and the Benefits

NPK stands of Nitrogen (N), Phosphorus (P) and Potassium (K). These are essential nutrients that plants need in order to stay alive. Let’s talk about what each nutrient does for plants.

Nitrogen – is mostly responsible for growth. Too much and the plant grows too fast and becomes vulnerable to disease and pests. Fast growth is not always best for your garden or yard.

Phosphorus – helps roots and flowers grow and develop.

Potassium – is important for overall plant health

It’s important to know that your plants will benefit more from healthy soil than any fertilizer you spread on the soil. If the soil is sterile of beneficial microbes, your plants will not be able to absorb the fertilizer. It’s all about the soil. If you take care of the soil, you won’t need any chemical fertilizers and your plants will be much healthier.

How to take care of your soil.

Mix or till a good compost in with your soil each year plus add 2-3 inches of compost on top of your soil. You can also add some Mycorrhizal also. This will introduce beneficial microbes to the soil. Compost will also help with beneficial microbes.

Even better than compost is Worm Castings. Add some worm castings on top of your soil once or twice a year for the ultimate organic fertilizer. Watch your plants grow and produce.

A healthy and rich soil will contain organic material, minerals and beneficial microbes.
