About This Book
The work explains the chemical basis of lasting soil fertility, presenting the ten essential plant elements and focusing on economical solutions for nitrogen and phosphorus supply. It summarizes long-term field experiments demonstrating substantial yield and profit gains from phosphate use, compares forms and costs of phosphorus fertilizers, and links nutrient management to farm profitability and future land value. Practical chapters describe how to detect deficiencies and implement systems that rebuild and conserve soil reserves, arguing that scientific understanding of plant nutrition is essential to sustainable, productive agriculture.
