Nitrogen content and C-Organic in the field for tropical fruit plantation in Jinengdalem Village, Bali, Indonesia

Abstract

This explorative research aims to find out reserves of total nitrogen and soil organic carbon on land for tropical fruit plantations in Jinengdalem Village, Buleleng District, Bali. Climate change will affect the availability of nutrients for these plantations. This research was conducted from December 2019 to June 2020. Soil sampling was carried out based on SNI 7724: 2011. The total nitrogen content of the soil in the sample was determined by the Kjeldahl method and the organic carbon stock in the sample was determined by the Walkley and Black method. The results showed that the total soil nitrogen and soil organic carbon obtained from samples 1 to 5 were respectively 0.007%, 0.00152%, 0.00151%, 0.006%, 0.006%, and 0.003% and for soil organic carbon were 0, 3733%; 0.4200%; 0.5133%; 0.5600% and 0.5133%. The content of soil nitrogen and organic carbon in this soil is very low because the level is less than 1%.

Effect of Farming Systems on Soil Carbon Sequestration and Crop Yield of Paddy (Oryza sativa L.) in Irrigated Rice Field

“…The parameters researched included soil volume weight by paraffin-clod method (Negro et al, 2018), texture by pipette method (Igaz et al, 2020), pH by potentiometric method (Lisak et al, 2015), soil C-organic by Walkley and Black method (Harahap et al, 2020), microbial biomass C by fumigationextraction method (Heuck et al, 2015), C-organic of rice plants by Walkley and Black method (Gunamantha et al, 2021), rice yield (Nyamai et al, 2012) in Indonesia. This was conducted with observations of 1,000 grain weight, productive tillers, number of clumps per hectare, and number of grains per panicle (Sari, 2023), root volume by volumetric method, and root weight by gravimetric method.…”
