Abstract

This research discusses the critical role of phosphatase enzymes in soil, particularly in the phosphorus cycle and soil fertility. Acid and alkaline phosphatases are identified as crucial components, with their activities serving as indicators of soil fertility. This study evaluates the soil chemical and biological characteristics in mangosteen orchards in the Mangosteen Thematic Village, specifically in monoculture and polyculture cultivation patterns on slopes ranging from 8-15%. Soil pH, organic C, available P, total P, soil respiration, microbial C-biomass, and phosphatase enzyme activities were assessed at 0-20 cm and 20-40 cm depths. Total P did not show significant changes based on cultivation patterns. The results show that the soil pH values tend to be acidic to slightly acidic (5.21- 5.45) with no significant differences based on depth. Organic C, available P, soil respiration, microbial C-biomass, and acid phosphatase enzyme activity were higher in polyculture cultivation patterns but alkaline phosphatase enzyme activity was higher in monoculture. The cultivation pattern influences the dynamics of agricultural ecosystems and should be considered in land management to enhance productivity and soil ecosystem balance.

Abstract

Fly ash berpotensi digunakan sebagai pembenah tanah dan  sumber hara tanaman, karena bersifat basa (pH 8-12), kadar hara silika tinggi, mengandung hara makro dan mikro yang dibutuhkan tanam. Penelitian bertujuan untuk mengetahui pengaruh aplikasi fly ash terhadap  kadar hara makro, silika dan logam berat pada tanah, tanaman, dan gabah serta hasil padi sawah.  Penelitian dilaksanakan dari bulan Juni-Desember 2024. Penelitian disusun dalam Rancangan Acak Kelompok  9 ulangan dan  3 perlakuan (Tanpa fly ash, 5 ton fly ash+1 ton pupuk kandang/ha, dan 5 ton fly ash/ha). Variabel yang diamati yaitu: 1) sifat kimia tanah dan kandungan logam berat sebelum dan sesudah perlakuan, 2) kadar hara makro, silika dan logam berat  dalam jaringan tanaman dan gabah, 3) pertumbuhan tanaman, komponen hasil, dan hasil/ha. Hasil penelitian menunjukkan bahwa tingkat kesuburan tanah tergolong rendah. Pemberian fly ash meningkatkan   C-organik,  P-total,  P-tersedia, Si-tersedia dan dan menurunkan kadar logam berat. Aplikasi fly ash meningkatkan kadar Si tanaman dan menurunkan kadar logam berat dalam jaringan tanaman dan gabah, meningkatkan anakan produktif dan hasil. Hasil tertinggi (8 t GKP/ha) didapatkan pada perlakuan 5 ton fly ash + 1 ton pupuk kandang/ha.

Abstract

Small-scale goat farmers in Nagari Palaluar, Koto VII District, Sijunjung Regency have a dual challenge in the form of low profitability of goat farming and degradation of agricultural land due to excessive use of inorganic fertilizers and conversion of former mining land. This community service initiative aims to increase farmers' income by converting goat manure waste by processing goat manure waste into Liquid Organic Fertilizer, while supporting sustainable agricultural practices. Using a participatory rural appraisal (PRA) approach, the program combines theoretical education, LOF (Liquid Organic Fertilizer) making practice training, technical mentoring, and laboratory-based evaluation. The results showed a very significant increase in knowledge (p < 0.001) with an average gain score of 39.00 (from 48.33 to 87.33). Laboratory analysis confirmed the quality of POC with macronutrient concentrations of Nitrogen (235.5 ppm), Phosphorus (299.7 ppm), and Potassium (714.7 ppm) at Level 1 (Very High), as well as an optimal pH of 6.8. The participants managed to produce 160 liters of LOF per month, creating a new source of income through local sales while reducing dependence on chemical fertilizers. This integrated approach not only increases the income of goat farmers but also promotes a circular economy, reduces environmental impact, and contributes to SDGs 12 and 15
