摘要: Abstract A simple accurate method of preparing soil samples for analyses soluble and exchangeable ions is presented. suspension prepared from that have been taken on a volume basis the concentration nutrient in solution phase this determined (concentration c1). An amount water equal to then added again c2). The c=c1c2/(c1‐c2) volume‐basis. Provided it feasible take adequate quick‐tests are available, management fertility could be greatly improved by method.
