Eggshells also are known to lower the pH content of overly acidic soils, and help aerate the ground, and that is very important, as the soil can become compacted over time, which prevents plant roots from getting the oxygen they need.
蛋殼還可以降低過酸土壤的 pH 值,並幫助土壤透氣,這一點很重要,因為土壤會隨著時間變得越來越緊實,讓植物根部無法獲得其所需要的氧氣。
