About Lesson
  • The objectives of this test are to determine the amount of nutrients that must be added to soil at different soil test levels of that nutrient to obtain maximum yield.
  • After the analysis of soils, data are obtained and these data are grouped into different classes.
  • This grouping is based on crop responses obtained in greenhouse studies (pot culture).
  • The composite soil samples are obtained from the field for pot- culture plant studies to access the crop response to added fertilizers and calibrate response to soil-test value obtained.
  • This classification indicates that very low and low classes of soil would markedly response to added fertilizer and the soil of high and very high would not respond to the fertilizer.
