Objectives

  1. To evaluate the potential leaching losses of soil P and N;
  2. To determine crop nutrient (N, P, K) uptake and removals;
  3. To determine the relationships between fertilizer P and K and quality of processing tomatoes under drip irrigation in according with the newly developed N rate in Ontario; and
  4. To develop the optimum rates of P and K under Ontario conditions, that minimizes potential for P losses, while meeting the needs for maximum quality and economic yield.
