Analyst's Comments

The medium ranges shown are the higher of either the minimum requirement for lush grass growth or animal nutritional requirements fed on an 'ad-lib' basis.

The boron level in mixed herbage is especially difficult to interpret. This is because grasses typically have 5 - 10 mg/kg and clover 18 - 25 mg/kg, making the mixed herbage B level very dependent upon the relative proportions of grass and clover in the sample. It is further complicated by the natural seasonal trend of low levels of boron during winter/spring c.f. higher levels in summer/autumn. As a consequence, we no longer provide a graphical interpretation for B in mixed herbage. A clover-only sample is recommended for monitoring boron status in pasture.

Summary of Methods

The following table(s) gives a brief description of the methods used to conduct the analyses for this job. The detection limits given below are those attainable in a relatively clean matrix. Detection limits may be higher for individual samples should insufficient sample be available, or if the matrix requires that dilutions be performed during analysis.
