Fertilization and irrigation mistakes are expensive
Fertilization and irrigation decisions directly affect yield, quality, input efficiency, soil conditions, and crop development. Errors in interpretation, timing, fertilizer choice, water quality, or irrigation scheduling can create problems that are difficult to correct later.
This book gives growers, agronomists, consultants, and fertilizer professionals a clear foundation for making those decisions with more confidence.
It connects the main principles behind soil analysis, water quality, plant nutrition, fertilizer behavior, fertigation, irrigation scheduling, and hydroponics – so the reader can understand not only what to do, but why.
Written by Guy Sela, agronomist, author, founder of Cropaia and yieldsApp, with more than 25 years of experience in plant nutrition, irrigation, fertigation, water quality, and practical crop management across different crops and production systems.
Throughout 260 pages, the author shares his knowledge on the most important aspects of crop nutrition and irrigation – from soil analysis and water quality to fertigation, irrigation scheduling, and hydroponics.
The Fertilization and Irrigation book is a practical reference for the decisions growers and agronomists face repeatedly: How to interpret soil and water analysis · How to plan fertilizer applications · How to manage fertigation · How to schedule irrigation · How to avoid common mistakes that reduce crop performance.

The essential agronomic knowledge – in one book
Most growers and agronomists piece together their knowledge from scattered sources – articles, manuals, and field experience. This book brings the main concepts together and connects them to practical decisions.
- ✓Essential plant nutrients – their roles and behavior in soil and plant tissue
- ✓Irrigation water quality – parameters, testing, and interpreting water analysis
- ✓Soil testing – how to test your soil and interpret any soil test report
- ✓Soil properties – the key characteristics that drive nutrient availability
- ✓Fertigation – best practices for applying fertilizers through irrigation systems
- ✓Fertilizer recommendations – how to build and adapt a fertilization program
- ✓Irrigation scheduling – soil-based, weather-based, and plant-based methods
- ✓Hydroponics – how to formulate and balance nutrient solutions
And more – organic fertilization, slow-release fertilizers, nutrient deficiency diagnosis, and water management in soil.
