    • The invention provides a composition in concentrated form ("the concentrate") for dilution with water in the preparation of an agricultural composition for application to crops, soil or animals, comprising a carbohydrate-based pH modifying agent and a pH indicator. The agricultural composition comprises an agricultural chemical whose agricultural activity varies with the pH of the water. The proportions of the pH indicator and the pH modifying agent in the concentrate are selected so that when the concentrate is diluted with an appropriate amount of water, the pH indicator indicates visually by colouration of the composition, whether or not the pH of the water is suitable for acceptable agricultural activity of the chemical. The invention also provides a process for preparing the agricultural composition by mixing the concentrate with water, and adding the agricultural chemical to the composition, if it is not already present in the concentrate.
    • 本发明提供了一种浓缩形式的组合物(“浓缩物”),用于在制备用于施用于作物,土壤或动物的农业组合物中用水稀释,其包含基于碳水化合物的pH调节剂和pH指示剂。 农业组合物包括农业活动随着水的pH而变化的农药。 选择浓缩物中的pH指示剂和pH调节剂的比例,使得当浓缩物用适量的水稀释时,pH指示剂通过组合物着色指示,无论水的pH是否为 适合化学品的可接受的农业活动。 本发明还提供了一种通过将浓缩物与水混合并将农药添加到组合物中(如果它还没有存在于浓缩物中)来制备农业组合物的方法。
