Analysis of soil physical quality index (case study: groundnut/ Arachis hypogeal L.)

Abstract

Physical properties of soil are good for plant growth is closely related to the management of the soil, so it will need to integrate of physical properties to get an overall assessment with making soil physical quality index (SPQI). This study aims to an evaluation of physical properties and determines the physical quality index using several unit treatments to produce various physical qualities on Groundnut/Arachis hypogeal L. The location of the research was carried out in a farmer's garden in Cimaung Village, Cikeusal District, Serang Regency, Banten Province (Coordinates 6o12’14’’ S dan 106o11’52’’E). To analyze the SPQI using several physical properties of the soil such as texture, bulk density, porosity, permeability, and aggregate stability. Each indicator has a scoring parameter to assess the soil physical quality index with a score range of 0-5. An assessment SPQI in a land unit is able to describe the various physical qualities of the soil which are represented by several physical properties of the soil. The unit treatment which class categorization of soil physical quality index indicated slightly good (U2), medium (U1, U3-U6), and slightly poor (U7) as a control.

Analisis Indeks Produktivitas Tanah Untuk Meningkatkan Pengembangan Kacang Tanah di Desa Cimaung, Banten

“…Kandungan C-Organik tanah yang rendah yaitu hanya 0.33% masuk kedalam kategori sangat rendah, padahal C-organik merupakan bagian dari faktor pendukung penting untuk pertumbuhan dan perkembangan tanaman. Dengan demikian perlu dilakukan penambahan bahan organik karena bahan organik merupakan dasar untuk menentukan persentase C-Organik (Riskawati, 2021). Cherubin et al (2016) juga menambahkan bahwa tindakan pengelolaan lahan dengan melakukan penambahan bahan organik tanah dapat mendukung produktivitas tanaman.…”
