A study was conducted to evaluate the use of P vectors to predict the amount of P required on a yearly basis to maintain a constant solution-solid phase P relationship in an irrigated calcareous and a dryland acid soil. Irrigated potato-spring barley and dryland spring pea spring-barley crop rotations established at the two locations. Mono-calcium phosphate (0-45-0) was applied annually at five levels, ranging from 0-4 times estimated crop removal. Phosphorus vectors were determined on soil samples by equilibration with standard P solutions. Yields tended to increase with added P on the calcareous soil; however, significant responses were not recorded at either location. Consequently, critical P vectors were not established. A constant solution-solid phase P relationship was maintained by addition of P equal to that removed by the crop on the calcareous soil. A constant solution-solid phase P relationship was not maintained on the acid soil. |
