Abstract

Soil moisture is an important factor needed by plants for growth, and therefore the amount of soil moisture that can be stored depends on the type of soil or the composition of the soil-forming materials. Compost is one of the nutrients that is often used in the manufacture of planting media on land in the form of polybags, and the amount of compost composition on the soil is thought to greatly affect the ability to store water in the media. This study aims to test drip irrigation on a mixture of compost and soil on storage of irrigation water. Tests were carried out at a ratio of 70%: 30%, 50%: 50% and 30%: 70%. Irrigation was tested at a duration of 5 minutes, 10 minutes, and 15 minutes, and the data analyzed included irrigation distribution data, discharge, soil moisture data (w) and daily soil moisture change data. The results of the analysis are presented in the form of tables and graphs, then discussed and concluded descriptively. The results of the analysis show that the flow rate obtained is greater if the difference in water level to the land is greater, and the average Cu value obtained is 95.79% which is very good. With initial soil moisture in the range of 19%-25, soil moisture gain obtained by drip irrigation for 5 minutes -10 minutes is around 12%, and for a duration of 15 minutes soil moisture gain is obtained by 8% -21%. The lowest recharge was obtained on land with 30% soil and 70% compost of 8%-12%. The amount of soil moisture reduction after 24 hours of irrigation test was 6% - 17%, the lowest reduction was at 70% compost and 30% soil around 6%.

土壤和堆肥介质的吸收和降解土壤透镜能力
土壤水分是植物生长所需的重要因素,因此土壤水分的储存量取决于土壤类型或成土物质的组成。堆肥是在土地上以塑料袋的形式制造种植介质时经常使用的营养物质之一,土壤中堆肥成分的含量被认为对介质中水分的储存能力有很大影响。本研究旨在测试堆肥与土壤混合滴灌对灌溉水储存的影响。试验分别在70%:30%、50%:50%和30%:70%的比例下进行。灌溉时间分别为5分钟、10分钟和15分钟,分析数据包括灌溉分布数据、流量、土壤水分数据(w)和土壤水分日变化数据。分析结果以表格和图表的形式呈现出来,然后进行了描述性的讨论和总结。分析结果表明,与地面水位差越大,得到的流量越大,平均Cu值为95.79%,效果很好。在初始土壤水分19%- 25%范围内,滴灌5分钟-10分钟获得的土壤水分增益约为12%,滴灌15分钟获得的土壤水分增益为8% -21%。土壤占30%,堆肥占70%,回收量为8% ~ 12%,回收量最低。灌溉试验24 h后土壤水分减少量为6% ~ 17%,堆肥70%时土壤水分减少量最小,30%土壤水分减少量在6%左右。
