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.
