Days In Summer Months With Mild Soil Water Stress In A 0.6m Sandy Clay Loam

This dataset contains the soil water stress in South Africa. The importance of soil water content in agricultural applications is vital since the need to irrigate occurs when the actual soil water content is less than the critical soil water content at which plant stress commences. The objective of soil water stress mapping was to determine, for each Quaternary Catchment (QC) with its unique rainfall, temperature and potential evaporation climate, the number of days per year at which soil water content would be at critical plant stress/no stress levels.

本数据集包含南非地区的土壤水分胁迫信息。土壤含水量在农业应用中至关重要，因为当实际土壤含水量低于植物胁迫开始时的临界土壤含水量时，灌溉需求便会产生。土壤水分胁迫制图的目标是，针对每个具有独特降雨、温度和潜在蒸发气候特征的第四纪流域（Quaternary Catchment，QC），确定每年土壤含水量处于临界植物胁迫/无胁迫水平的天数。
