摘要

土壤水分左右土體化學和植物體反應。當水分不足，植物和其根系生長受阻，將影響農產品品質；更甚者，在達永久凋萎點前無適時補充水分，植物將死亡。水分由灌溉或降水量提供，惟降水量在全球氣候變遷下，呈不規律極端變化，非旱即澇。因此，土壤水分的保持在農業生產上是一關鍵。草生栽培不是放任雜草叢生，適時管理，存在之植被有助土壤水分調節、維持土壤溫度、控制雜草並對土壤肥力提升甚有助益。

Lack of available water reduces root and plant growth, and it can lead to plant death if sufficient moisture is not provided before a plant permanently wilts. The water is supplied by irrigation or precipitation, but precipitation variation is rapidly. The amount of water held by the soil may be critical in agriculture. Vegetation can increase moisture retention, control weeds, maintain a uniform soil temperature, and increase soil fertility.
