| Abstract/Contents: | "Urban development in the US-Mexico border region has led to an increase in impervious surfaces and soil compaction as due to construction activity. In addition, soils and substratum in this region contain an appreciable amount of expansive clay, which is prone to surface crusting and sealing. The effect is increased stormwater runoff with the threat of urban flooding. The objective of this study is to evaluate soil remediation methods to improve infiltration on urban compacted land, consisting of tillage and/or compost amendment. A field-testing site (~ 0.13 acre) was established at the University of Texas Rio Grande Valley (UTRGV) Edinburg campus following completion of on-site construction activities. The site received four different land treatments in five replicated trials on a randomized complete block design: 1) tillage only, 2) compost only, 3) tillage + compost, and 4) control (no tillage + no compost). Tillage was done by a rear tine tiller (up to 15 cm in depth). Compost was obtained from a municipal composting facility and it was applied in 5-cm depth. For compost + tillage treatment, compost was incorporated during the tillage. A total of 20 plots (each plot sized in 3.5-m width and 4-m length) were hydroseeded with common Bermuda grass in June, 2018. Monitoring of relevant soil physical properties is in progress, including infiltration rate, bulk density, and penetration resistance. Water runoff samples collected from the Infiltration test methods were analyzed for phosphate, Nitrate, and ammonia before and after fertilization. Our preliminary data showed that tillage and compost amendment resulted in thicker and greener turfgrass establishment and promoted infiltration by 3-4 times compared to control treatment. The outcome of this study will have broad impacts in both US and Mexico in restoring urban lands and promoting infiltration, especially where groundwater recharge is desirable." |
