Effects of Lime and Compost on Chemical Characteristics and Soil Hydraulic Conductivity of Alfisols at ATP Jatikerto Coffee Plantation

Abstract

<span>Coffee in Indonesia is currently one of the most important plantation commodities. Inappropriate management of coffee plantations causes low soil quality especially in smallholder coffee plantations, one of which is the density (compaction) of soil in coffee plantations that has a clayey</span><span> t</span><span>exture. This study was aimed to analyze the effect of lime and compost application on the chemical characteristics and saturated hydraulic conductivity (SHC) of the soil. The experiment was carried out at Glasshouse Agro Techno Park (ATP) Jatikerto from September 2020-February 2021. Soil samples were taken from coffee gardens at a depth of 0-30 cm and 30-60 cm. The incubation study in the greenhouse used Factorial Complete Randomized Design with 12 treatments and 3 replications. Incubation was carried out for 8 weeks. Treatment factors include the depth of the soil sample (0-30 cm and 30-60 cm); compost (0 tons ha<sup>-1</sup>, 10 tons ha<sup>-1</sup></span><span lang="IN"> and</span><span>20 tons ha<sup>-1</sup>) and lime (0 tons ha<sup>-1</sup> and 2.5 tons ha<sup>-1</sup>). Results showed that the treatment combination of </span><span lang="IN">2.5 ton ha<sup>-1</sup> of </span><span>lime and </span><span lang="IN">20 ton ha<sup>-1</sup> of </span><span>compost gave the best results measured by the availability of N and K nutrients and an increase in the </span><span lang="IN">SHC</span><span>. However, results in this treatment were almost the same as treatment of </span><span lang="IN">2.5 ton ha<sup>-1</sup> of </span><span>lime and </span><span lang="IN">10 ton ha<sup>-1</sup> of c</span><span>ompost. </span><span>The combination of compost and lime has a significant effect on improving the chemical characteristics of the soil and the </span><span lang="IN">SHC </span><span>of the topsoil (0-30 cm) and the subsoil (30-60 cm).</span>

Application of Compost and Manure in the Biopore Infiltration Hole to Improve Saturated Hydraulic Conductivity (Shc) of Soil in the Coffee Root Zone

“…This triggers increasing of SHC values of a dense soils in coffee fields. In line with the research of Fitria & Soemarno (2022) explained that application of organic fertilizers tends to reduce soil density and it results in higher value of soil permeability. The magnitude of the soil permeability rate is also influenced by soil aggregates stability and content of soil organic matter.…”

“…The finer the soil fraction, the more surface area particles, so it has a higher CEC. In addition, (Fitria & Soemarno, 2022) also discuss the results of their research that an increase in soil pH has the potential to increase the CEC value of the soil, this result will affect the availability of nutrients in the soil.…”

Evaluation of Aggregate Stability Using the Slaking Index Method with Soil Physical Approach in Keduang Sub-Watershed, Indonesia

“…The aggregate stability is correlated to soil properties such as sand/quartz content smectite. It is highly correlated with Ca 2+ exchange capacity, indicating that soil hardening can be reduced by applying calcium products such as gypsum and dolomite (Almajmaie et al, 2017;Fitria and Soemarno, 2022;Cahyono et al, 2023).…”

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

“…Meanwhile, organic fertilizers can increase soil carbon stock (Waqas et al, 2020). Organic farming systems enhance soil pH and hasten decomposition in humic compounds (Fitria and Soemarno, 2022). Leifeld and Fuhrer (2010) mentioned that this systems had higher soil organic carbon storage than conventional farming.…”
