Abstract

Pesticides are widely used in agriculture, including on peat soil. The objective of this study was to analyze the effect of the application of paraquat, difenoconazole, and butylphenyl methylcarbamate (BPMC) on CO2 emissions and concentrations of phenolic acids in a peat soil. Peat soil sample was taken in District of Pulang Pisau, Central Kalimantan. The peat soil was applied with 1.89 mg kg-1 paraquat, 1.72 mg kg-1 difenoconazole and 1.65 mg kg-1 butylphenyl methylcarbamate (BPMC), then the soil was incubated for 1, 2, 4 , 5, 7, 10, 14, 21, 26 and 30 days. The results showed that the application of pesticides on peat soil increased CO2emission, and decreased CH4 emission and phenolic acid concentrations up to 30 days of incubation. The CO2 emmisions were derived from C of degraded pesticides and from C of phenolic acids, although the oxidation reaction was not accompanied by the change of soil pH. Keyword: CO2 emission, phenolic acids, butylphenyl methylcarbamate (BPMC), difenoconazole, paraquat, peat soil

Abstract

Land use in Bogor Regency has diverse vegetation and different soil characteristics. Soil characteristics have an influence on land management. Improper land management has led to a decrease in microbial populations, biodiversity and a decline in soil quality and fertility. Soil fertility is produced by the interaction of the physical, chemical, and biological properties of the soil. This study aims to determine the correlation of soil biological and chemical properties in several different types of land use in Bogor Regency. Soil sampling was carried out using the purposive random sampling method with five replicates. Soil samples were taken at a depth of 0-20 cm by ±1 kg. The research site includes eight land uses namely bamboo gardens, sengon gardens, lamtorogung gardens, and dragon fruit orchards. The results of the analysis showed that the dragon fruit field had an acid pH with very high organic C and total N levels with the highest fungal population of 2.27 x 105 CFU g-1. Meanwhile, bamboo fields with an acid pH also have a medium organic C content and low total N with the lowest total fungi population of 0.37 x 105 CFU g-1. Azotobacter populations and respiration values had the highest correlation with the total P content of the soil. The correlation value of the total population of fungi was the highest, with a total N levels of 0.427.

Abstract

The price of the AB mix is relatively high, so it needed to find another alternative with a more economical price. One of the alternatives is Liquid Organic Fertilizer (LOF). This study aimed to know the quality of LOF made from banana peels and chicken egg shells, the effect of LOF on the water spinach grown in the hydroponic wick system, and the possible use of LOF as a substitute for AB mix. The experiment consisted of three stages. The first stage was the nutrient analysis of raw materials. The second stage was the production of LOF and nutrient analysis. The results of fermented fertilizers are called POC PT. The third stage was an experiment on water spinach in a hydroponic wick system. The experiment used a completely randomized design with five fertilizer treatments, namely P0 (control), P1 (AB mix nutrition), P2 (LOF PT 150%), P3 (LOF PT 100%), P4 (LOF PT 50%) in three replications. The results showed that LOF, which was fermented for three weeks, had a low nutrient content and was below the Ministry of Agriculture standard. The available N content in POC PT was low, so Ca(NO3)2 fertilizer was added to POC PT. The LOF PT treatment had higher plant growth parameter than the control treatment. Thus, the treatment of LOF PT could not substitute AB mix.

Abstract

Pineapple is a leading commodity worldwide and can grow in a variety of mineral and organic soils. Excessive use of inorganic fertilizers has a detrimental impact on soil and crop health. Biofertilizers contain beneficial microorganisms that can enhance soil fertility, improve soil health, and promote sustainable crop production. This study aimed to investigate the crucial role of biofertilizers and mycorrhizae in promoting the vegetative growth of pineapple in acidic soils. The experiment was conducted using a completely randomized design with nine treatment levels and five replications. The results showed that the mycorrhizae applied at 5 g per plant, combined with full doses of chemical fertilizer (0.5 g ZA, 2 g DAP, and 2 g KCl per plant), produced the highest mycorrhizal colonization in treatment P4. Meanwhile, Provibio® biofertilizer at 5 mL per plant (diluted in 0.5 L water), mycorrhizae at 2.5 g per plant, and half doses of chemical fertilizer (0.25 g ZA, 1 g DAP, and 1 g KCl per plant (P8), improved vegetative growth and soil properties (pH, organic C, and total N) and supported the highest microbial population in the rhizosphere (26.05 × 10⁴ CFU.g-1 soil). This study demonstrated that the combined application of biofertilizers and mycorrhizae in moderate doses is more effective than full single-dose applications, leading to healthier soils and stronger vegetative growth of pineapple in acidic soils.

Abstract

Potensi Pupuk Hayati Mikoriza pada Bawang Daun (Allium Fistulosum L.) di Andosol Wonoboyo, Temanggung - Jawa Tengah. Bawang daun (Allium fistulosum L.) merupakan komoditas bernilai ekonomi tinggi dengan potensi ekspor, terutama ke pasar Asia Timur. Namun, budidayanya pada tanah andosol menghadapi tantangan berupa rendahnya ketersediaan fosfor akibat fiksasi oleh mineral tanah dan sistem perakaran tanaman yang dangkal. Penelitian ini bertujuan menganalisis aplikasi pupuk hayati mikoriza dan pupuk P terhadap pertumbuhan dan produktivitas tanaman bawang daun (Allium fistulosum L.) yang ditanam pada andosol di Kec. Wonoboyo, Temanggung, serta mengevaluasi perubahan kandungan hara NPK tanah, tingkat infeksi mikoriza pada akar tanaman, juga jumlah sporanya. Penelitian dirancang menggunakan Rancangan Acak Kelompok faktorial dua faktor: dosis mikoriza (0 dan 500 kg/ha) dan pupuk P (0 dan 200 kg/ha). Hasil menunjukkan bahwa tinggi tanaman pada 12 dan 13 MST berbeda nyata antar perlakuan, di mana perlakuan mikoriza tanpa pupuk P (M1P0) menghasilkan tinggi tanaman secara signifikan lebih tinggi dibanding kontrol dan kombinasi M1P1. Parameter kimia tanah setelah penanaman dan serapan hara NPK tanaman juga menunjukkan tidak adanya perbedaan signifikan antar perlakuan. Perlakuan M1P0 memberikan respon terbaik terhadap pertumbuhan dan produktivitas tanaman, serta menghasilkan jumlah spora mikoriza dan tingkat infeksi akar tertinggi dengan genus spora dominan adalah Glomus.

Abstract

Consumption of sweet corn has increased from 2021 to 2024. To meet the growing market demand, sweet corn production must be carried out in a sustainable, economical, efficient, and environmentally friendly manner. The use of a combination of sludge, rice husk charcoal, compost, and inorganic fertilizer was tested to enhance corn plant growth and productivity. The study was conducted at the Cikabayan Experimental Farm, IPB University, using a Randomized Complete Block Design (RCBD) with five treatment levels and three replications. The results showed that treatment S2H1 (75% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) exhibited the best vegetative and generative growth (stem diameter, number of leaves, ear length, biomass weight per plot, and ear weight per plot). The S1H1 treatment (100% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) showed improved biological and chemical soil quality (pH, organic carbon, total nitrogen, total phosphorus, and base saturation). All treatments resulted in an R/C ratio above 1, indicating economically viable potential. The results indicate demonstrate that the combined use of sludge and organic materials allows NPK fertilizer inputs to be reduced by 25%, supporting sustainable agriculture.

Abstract

Industrial wastewater sludge is rich in organic matter and nutrients and has the potential to be used as a amendments despite its high moisture content (91,87%). Rice husk charcoal can address moisture and heavy metal content to achieve quality standards. This study aims to determine the optimal combination of each material and to investigate the correlation between chemical and biological properties. Incubation of the growing medium (sludge, rice husk charcoal, compost) was conducted using seven different material combinations with a completely randomized design. Soil chemical analysis (pH, organic carbon, N, P, K, KTK) and soil biological analysis (total microbes and fungi) were conducted after one month of incubation. The results showed that MSG sludge is nutrient-rich (organic carbon 46.63%, N 7.30%) but Fe (27,836 ppm) and Pb (54 ppm) exceed the limits. Treatment P1 (100% sludge, 75% rice husk charcoal, and 50% compost) had the highest total microorganisms and fungi (0.75 × 10⁵ CFU/g and 0.88 × 10⁵ CFU/g), as well as the highest pH, organic carbon, N, P, K, and KTK. Fe increased while Pb decreased. Treatment P1 was the best combination and met the quality standards for soil conditioners. Microbes and fungi were positively correlated with pH. KTK was positively correlated with pH and organic carbon. An increase in pH had the highest positive correlation with the growth of microbes and fungi.
