20 Best Fertilizer For Clay Soil (2023 Updated)

Clay soil is a type of soil that is made up of very small particles of minerals. This soil is known for being very dense and compact. Because of its dense nature, clay soil does not allow water or air to move easily through it.

This can make it difficult for plants to grow in clay soil.

Fertilizer can help improve the quality of clay soil. Fertilizer adds essential nutrients to the soil that can help promote plant growth. It can also help improve the structure of clay soil, making it more porous and easier for roots to penetrate.
