Abstract

Agriculture in arid and semi-arid regions (ASALs) faces challenges due to limited water and problematic soils. This study investigates the potential of superabsorbent materials like Super Absorbent Polymers (SAPs) and pumice to enhance water retention and agricultural productivity in Ngubreti in Mogotio Sub-County, Kenya, representing ASALs. Using a randomized design with different material ratios and a control group, the research analysed soil parameters and plant growth indicators. Incorporating superabsorbent materials increased soil porosity, reduced bulk density, and improved water retention. Bell pepper production notably increased by 53.4%, with the SAP Pumice Double Half (SPDH) treatment showing the highest yield. This research underscores superabsorbent materials' ability to enhance ASAL soil conditions and agricultural output, particularly SPDH treatment. Precise material concentration control and consideration of their impact on soil penetration rates are crucial for optimal results. The study contributes to sustainable agriculture in water-scarce regions, emphasizing soil management's role in crop productivity. Further research and region-specific experiments are needed for broader applicability. Farmers are advised to assess their soil characteristics and consider a recommended median soil-additives mixing ratio of 1:833. Long-term effectiveness warrants additional investigation
超级吸水材料的混合比例对肯尼亚莫戈蒂奥铁质路维索尔中甜椒的生长和产量的影响
干旱和半干旱地区(ASALs)的农业因水资源有限和土壤问题而面临挑战。本研究调查了超级吸水材料(如超级吸水聚合物 (SAP))和浮石在提高肯尼亚 Mogotio 子县 Ngubreti(ASALs 的代表)的保水性和农业生产率方面的潜力。研究采用不同材料比例的随机设计和对照组,分析了土壤参数和植物生长指标。加入超吸收材料增加了土壤孔隙度,降低了体积密度,提高了保水性。甜椒产量显著提高了 53.4%,其中 SAP 浮石双半(SPDH)处理的产量最高。这项研究强调了超吸水材料改善 ASAL 土壤条件和农业产量的能力,尤其是 SPDH 处理。精确控制材料浓度并考虑其对土壤渗透率的影响对于取得最佳效果至关重要。这项研究有助于缺水地区的可持续农业,强调了土壤管理对作物产量的作用。要想获得更广泛的适用性,还需要进一步的研究和针对特定地区的实验。建议农民评估自己的土壤特性,并考虑将土壤添加剂的混合比例中值定为 1:833。长期有效性需要进一步调查
