Abstract
PurposeThis study aimed to discover the precise material composition and thickness (water hyacinth, rice straw, and banana pseudostem) of organic mulch sheet.MethodsThis current research was conducted by means of a number of treatments with various material compositions and thickness of organic mulch sheet. Several tests were administered such as chemical analyses on organic mulch sheet, tensile strength, and Vilensky test.ResultVarious compositions of materials resulted in various chemical analyses of organic mulch sheet. Organic mulch with the strongest tensile strength was during the treatment of 60% water hyacinth, 20% rice straw, and 20% banana pseudostem, reaching 3.28 N/m2. The highest sunlight intensity of mulch composition was during the treatment of M4 (50% water hyacinth, 40% rice straw, and 10% banana pseudostem) with no hole and absorbing.ConclusionThe result showed that water hyacinth, rice straw, and banana pseudostem could be used as the materials for organic mulch sheets. They could add organic matters into the soil, have endurance and strength to apply as mulch in crop cultivation, as well as help plants adapt to climate change.
Highlights
Mulch is a soil cover that functions to maintain soil temperature and humidity, inhibit the growth of weeds, lessen soil erosion (Díaz-Pérez and Batal 2002; Kar and Kumar, 2007; Ekinci and Dursun, 2009; Sinkevičienė et al 2009; Ibarra-Jiménez et al 2011; Dvořák et al 2012)
Previous study showed 50% water hyacinth and 30 and 20% straw organic mulch sheet composition increased C-organic, N-total, and organic matter compared with 60% water hyacinth and 30% straw composition (Iriany et al 2016)
The organic mulch sheet was made of water hyacinth, banana pseudostem, and tannery waste
Summary
Mulch is a soil cover that functions to maintain soil temperature and humidity, inhibit the growth of weeds, lessen soil erosion (Díaz-Pérez and Batal 2002; Kar and Kumar, 2007; Ekinci and Dursun, 2009; Sinkevičienė et al 2009; Ibarra-Jiménez et al 2011; Dvořák et al 2012). In horticulture plantation, both organic mulch and inorganic mulch have been into a common use Some previous studies have found that mulch usage increases plant productivity (Siwek et al 2007; Miles et al 2012; Haapala et al 2015)
