Summary

Appropriate evaluation of soil phosphorus (P) availability is a prerequisite for best P management in potato production systems. Consequently, we evaluated soil test P and microbial biomass P in 10 rainfed and irrigated potato field soils which had a three-year crop rotation. Ammonium oxalate extracted P was the highest with a level of >1400 mg kg -1. Olsen P was moderate and ranged from 100 to 120 mg kg -1. Modified Morgan inorganic P (MMPi) was lowest (
