Objectives

The Laboratory for Soil Analysis has the following objectives:

  • Develop analytical capacity for research  in the area of soil management and soil fertility for the National Research Programs  on Pasture & Forage Plants,  Crops, Horticulture, Fruit Production, Meat and Wool, Dairy, etc.
  • Provide Soil,  Plant  and Water Analysis Service to farm consultants, cooperatives and individual farmers.
