Unlock the science behind fertilizer in plain terms that farmers and curious readers can apply. This volume guides you through the ideas behind soil fertility, why different soils need different plant food, and how experiments with fertilizers reveal the right choices for your crops. It explains the forms of key nutrients, what makes them available to plants, and how to evaluate the value of fertilizers beyond price.
The book covers practical topics you can use in the field: how soil variation affects crop needs, the concept of available vs. insoluble nutrients, and the difference between agricultural value and commercial price. It also includes examples of how manufacturers’ products are analyzed and rated for usefulness in farming, along with the limits of what any fertilizer can do for different crops and soils.
- Why soil and crop needs vary and how to test them with simple experiments
- How nitrogen, phosphoric acid, and potash exist in different forms and when they feed plants
