Soil Conditions And Micronutrients

Macronutrient fertilisers (NPK-fertilisers) are commonly given to plants as soil-added granules. The granules slowly break down in the soil, and the nutrients are absorbed through the plant’s roots.

With micronutrients, such as zinc and manganese, application through the soil can be affected by various soil conditions.
