Abstract

Utilization of slurry under the combination with mushroom baglog could be used a potential source for replacing nitrogen fertilizer and improve soil fertility. The purpose of this study was to evaluate the different combination and the level of slurry application combining with mushroom baglog on total soil nitrogen and organic contents, total soil bacteria and fungi, along with the improvement of growth and yield of strawberry (Fragaria x ananassa). The experiment used a complete randomized design with five treatments and five replications. The treatments were A1 (100% inorganic fertilizer application as control), A2 (50% composted slurry and mushroom baglog + 50% in-organic fertilizer), A3 (100%  composted slurry and mushroom baglog), A4 (150% composted slurry and mushroom baglog), A5 (50% composted slurry and mushroom baglog + 50% in-organic fertilizer), A6 (100% fresh slurry (uncomposted)), and A7 (150% uncomposted fresh slurry). Results showed that the treatments significantly affected total soil nitrogen, total soil bacteria and fungi, along with the growth and yield of strawberry. The A6 treatment which used 100% uncomposted fresh slurry, showed the highest total nitrogen in the soil (0.23%) and total population of bacteria (7.1 log CFU/g) and the greatest number of strawberry stolons. In term of the number of leaves and total soil fungi, the A3 treatment was the greatest, resulted in number of leaves and total soil fungi at 19.7 per plant and 4.8 log cfu/g x 104. However, the best yield was obtained from the A7 treatment (150% of fresh slurry) at 15.1 kg/ha.

Abstract

Alluvial soils play an important role in lowland ecosystems and agriculture due to their capacity to store organic carbon.  This study aimed to analyze land cover characteristics and spatial relationships between C-organic and land cover changes in the humid tropical alluvial landscape of East Kalimantan. The methods used in this study included spatial and statistical analyses to determine the relationship between C-organic and land cover. The results showed that land cover in the study area consisted of several main classes, dominated by Shrubland (29.56%), Mixed Dryland Agriculture and Shrubs (24.51%), and Plantation Areas (23.12%). The analysis of C-organic content revealed variation across different land cover types, with open land showing the highest C-organic content (2.30%). Pearson correlation analysis indicated a moderate negative correlation between C-organic and Shrubland(r = 0,4; p = 0,001), and a strong  positive correlation between C-organic and plantation forests (r = 0,9; p = 0,001), suggesting that land cover changes due to anthropogenic activities can affect soil C-organic content. This study indicates that land cover dynamics contribute to changes in soil C-organic content.

Abstract

ABSTRAK Meningkatnya permintaan produksi padi di Kota Samarinda, Kalimantan Timur, mendorong perlunya identifikasi wilayah pertanian baru. Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan potensial untuk sawah di wilayah Makroman dengan pendekatan berbasis bentuk lahan (landform). Analisis dilakukan berdasarkan karakteristik lahan pada satuan bentuk lahan yang berbeda, meliputi dataran banjir, berlereng, dataran berombak, dan dataran bergelombang. Evaluasi kesesuaian lahan dilakukan dengan metode pembatas sederhana atau pembatas maksimum untuk dua musim tanam, yaitu November–Februari dan Mei–Agustus. Karakteristik lahan yang dianalisis meliputi iklim, topografi, kelembapan, sifat fisik tanah, dan kesuburan tanah. Hasil menunjukkan bahwa dataran banjir memiliki tingkat kesesuaian tertinggi secara konsisten untuk budidaya padi, didukung oleh kondisi iklim yang menguntungkan dan kemiringan lahan yang datar. Sebaliknya, bentuk lahan berlereng dan dataran bergelombang menunjukkan tingkat kesesuaian yang lebih rendah akibat keterbatasan berupa kemiringan terjal dan drainase yang kurang sesuai. Faktor kesuburan tanah, terutama kandungan karbon organik yang rendah dan pH yang agak masam, menjadi kendala tambahan di sebagian besar satuan bentuk lahan. Penelitian ini menyimpulkan bahwa dataran banjir memiliki potensi tinggi untuk pengembangan sawah, namun diperlukan upaya pengelolaan lereng dan perbaikan sifat tanah di lahan marginal. Temuan ini memberikan masukan penting bagi perencanaan pertanian berkelanjutan di wilayah Makroman. Kata kunci: budidaya padi, evaluasi lahan, geomorfologi, pertanian, tanah.
