Abstract

Crop rotation is an environmentally friendly agricultural method that is effective in maintaining soil fertility and reducing pest attacks. This study aims to assess the impact of legume crop rotation, especially groundnut (Arachis hypogaea L.), on soil quality. The study was conducted through literature studies from various scientific sources. Results show that groundnut is able to improve soil through symbiosis with nitrogen-fixing bacteria such as Rhizobium sp. and encourage functional microbial activities such as nitrifying bacteria (Nitrosomonas sp. and Nitrobacter sp.). Crop rotation also increases organic matter content, improves soil structure, and increases the availability of nitrogen in the form of nitrate that is easily absorbed by plants. In addition, root exudates from groundnuts enrich the rhizosphere with beneficial microorganisms. Overall, legume crop rotation contributes greatly to improving soil fertility in a natural and sustainable manner.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi tingkat keasaman (pH) tanah serta mendiagnosis status unsur hara makro (Nitrogen, Fosfor, dan Kalium) pada lahan pertanian di Desa Banuagea, Kecamatan Tuhemberua, Kabupaten Nias Utara. Pengujian dilakukan menggunakan dua metode standar lapangan, yaitu Perangkat Uji Tanah Sawah (PUTS) untuk sampel tanah basah (Sampel Onodao’o dan Sampel Laehuwa) serta Perangkat Uji Tanah Kering (PUTK) untuk lahan demplot jagung. Hasil pengujian menunjukkan variasi tingkat keasaman yang signifikan: Sampel Onodao’o tergolong masam (pH 4–5) dengan tekstur berpasir, Sampel Laehuwa agak masam (pH 5–6), sedangkan Lahan Demplot Jagung memiliki kondisi awal masam (pH 4–5) yang berhasil ditingkatkan menjadi agak basa (pH 7–8) setelah pemberian pereaksi kapur (dolomit). Berdasarkan diagnosis hara, direkomendasikan aplikasi pemupukan spesifik lokasi, mencakup pemberian dolomit sebesar 1–2 ton/ha untuk menetralisir keasaman, penyesuaian dosis pupuk tunggal (Urea, SP-36, KCl), serta formulasi pupuk majemuk NPK 15:15:15 guna mengoptimalkan produktivitas komoditas pertanian lokal secara berkelanjutan.
