Fertilizer – What Do Plants Need

In my post Fertilizer: Selecting the Right NPK Ratio, I explained that you don’t feed plants – you feed the soil. Your job as a gardener is to add missing nutrients to the soil. If the soil contains all the nutrients plants need to live – the plants will do well.

The answer to the question, what fertilizer do plants need, is very simple. They need any nutrient that is deficient in the soil. If your soil is not deficient of nutrients – you do NOT need to fertilize.

But how do we know which nutrient(s) is deficient in the soil? I’ll try to answer this question in this post. In order to do that, we need to better understand what nutrients do in the soil.

Fertilizer – Understanding Plant Nutrients

Plant nutrient is a term used to describe plant food. We all know compost is good for the garden, but most of the good stuff in compost is not ready for plants to use – it is not plant nutrients yet! Over time, the complex molecules in compost, like proteins and carbohydrates, will be broken down by microbes into smaller molecules and eventually they become nutrients.

In this post I will take a close look at the main nutrients used by plants. What are they? What happens to them in soil? The answers to these and other questions will help you understand the process of fertilizing plants better.
