Soil erosion at pineapple plantations in Indonesia under the climate change issue

Abstract

Global climate change triggered the heavy and extreme rainfall in forms of intensity, pattern, duration, amount, and frequency. This condition strongly influences the occurrence of soil erosion, especially in the humid tropic region. The purpose of this research is to analyse the soil erosion rate under pineapple cultivation in Central Lampung, Indonesia. The results show rainfall erosivity using Bols equation is around 2109-3211 metric ton/h/ha. Soil erodibility is ranging 0.007-0.080 was categorized low to very low due to the amount of sand and silt is too low. The Slope also categorized low around 1-4%. The crop factor value is around 0.01-1. The rate of erosion in pineapple was 2016 is 1.51 ton/ha/year until 15 ton/ha/year; that value is under standard permissible erosion (18.5-25 ton/ha/year).

Soils erosion in pineapple (Ananas comosus L. Merr) producing areas

“…The equation proposes that annual soil losses are influenced by the erosion or aggressiveness of rain (R), soil erodibility or susceptibility to detachment (K), topographic factor (LS), coverage factor (C), and soil conservation practices (P). Although this equation has been applied in a large number of researches in different crops at an international level, the information on erosive processes in pineapple cultivation is still very scarce, especially at the planting level; therefore, the results reported in this regard are diverse for the different regions that have been studied (Afandi & Novpriansyah, 2020).…”

“…According to Afandi & Novpriansyah (2020) using USLE to calculate soil erosion cultivated with pineapple plants is complex, mainly to estimate the factor (C) of the crop. Pineapple has a long-life cycle and is harvested between 15 and 18 months after planting; then, it could be continued as a ratoon crop for about 15 months.…”

“…Soil losses in the field cultivated with pineapple will vary during pineapple growth. Thus, values ranging from 0.1 to 1 have been found, depending on the crop's phenological stage (Afandi et al, 2020). Abbasi & Jamal (1999) indicated that soil loss and runoff are more substantial during the first four months of pineapple crop establishment, and then it is gradually reduced due to the development of plan cover.…”

Economic Impact of Soil Losses in Pineapple Crops (Ananas Comosus L. Merr) In the Valle Del Cauca, Colombia

“…Hernández and Florentino (2004) evaluated the effect of different types of coverage and crop stages and their relationship with erosion. Álvarez and Peña (2013) and Afandi et al (2020) carried out studies on soil erosion in pineapple plantations, considering the in uence of factors such as erodibility and rain erosivity. However, the economic impact of soil erosion on this crop, concerning the loss of nutrients due to the effect of management practices, has not been reported or quanti ed.…”
