Up to the present we have been dependent for our knowledge of the nutrient requirements of New Zealand soils largely on the results of field trials established on. classified soil types, At the same time there has been much laboratory examination both of soils and pastures in connection with these trials. Although the field trial has served us well in the past and will probably always be regarded as the final arbiter in deciding the presence or absence of nutrient deficiency, it must be admitted that it has some drawbacks.
