Assistant Soil Fertility Officer, Lahore

The fertility status of soils under cultivation is a variable character. It is affected by cultural practices like cropping system, mannuring, fertilizer application and irrigation etc. Therefore, it is highly imperative to maintain fertility of soils at a level where nutrients are available to the growing plants in adequate quantities for realizing actual potential of different crops and cultural practices. The intensive cropping and growing high yielding varieties have resulted in deficiencies of various nutrients in the soils. It necessitates that these deficiencies be diagnosed promptly through soil testing, tissue analysis, field experimentation and replenished timely for obtaining optimum crop yields.

Simple fertilizer experimentation on farmers` fields is a well-established technique for diagnosing nutrient deficiencies in the soil and determining fertilizer needs of crops. In principle, this technique involves conducting trials on farmers` fields under varying agro-ecological conditions and cropping systems. This practice is though time consuming but it remains the most reliable method of diagnosing nutrient deficiencies and finding out the fertilizer requirements of different crops

Objectives

  • Assess fertilizer response in various agro-ecological zones / soil types in order to formulate  
  • economic fertilizer recommendations
  • Evaluate comparative agronomic efficiency of different commercial fertilizers
  • Find out appropriate time and method of fertilizer application in different cropping systems
  • Indexation of plant nutrients in soil and plant tissue for monitoring existing status
