The method is not suitable for fertilizers with Fe concentrations more than twenty times higher than the concentration of boron. This method is applicable to water and aqua regia fertilizer extracts obtained according to EN 16962 and\/or EN 16964. The method can also be used for the determination of boron in mineral fertilizers containing more than 10 % boron after appropriate dilution of the extracts.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>National foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>5<b><\/td>\n<td>European foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions <br \/> 4 Principle <br \/> 5 Sampling and sample preparation <br \/> 6 Reagents  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>7 Apparatus <br \/> 7.1 Laboratory glassware.  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>8 Procedure <br \/> 8.1 General <br \/> 8.2 Preparation of calibration solutions <br \/> 8.3 Preparation of the test solutions <br \/> 8.4 Preparation of the correction solutions <br \/> 8.5 Colour development  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>8.6 Measurement <br \/> 9 Calculation and expression of the result <br \/> 10 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>Annex A (informative) Verification data \u2014 Comparison of ICP-AES method and spectrophotometric method with azomethine-H  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Fertilizers.
