The Isothermal Phosphate Adsorption in a New Tidal Rice Field of Barito Kuala Regency South Kalimantan: A Study on Phosphorus Adsorption in Acid Sulfate Soils for Agricultural Improvement

Oleh: Yusran, Fadly Hairannoor, Mariana, Zuraida Titin, Devita, Windi Bunga

High P adsorption reduces rice production, especially in newly reclaimed paddy fields. The research studied soil P adsorption using the adsorption isoterm equation and soil P solubility in a New Tidal Rice Field of Barito Kuala Regency. This incubation study used soil samples from Ray 7, Balandean V...

Assessing the Impact of Terra Preta from Rice Husk on Soil, Rice Plant Growth, and Yield in the System of Rice Intensification (SRI)

Oleh: Adrinal, Adrinal

The practice of intensive rice field cultivation and the excessive application of chemical fertilizer often lead to issues such as a gradual decline in soil quality and fertility, as well as enviromental pollution. By employing Tetadi as ameliorant technology and adopting SRI cultivation techniques,...

Spatial Simulation of The Organic Carbon Content and its Effects on the Erodibility and Soil Erosion with Universal Soil Loss Equation and Geographic Information Systems

Oleh: Wijayanto, Yagus, Firmawati, Julvia Nurlaeli, Purnamasari, Ika

Universal Soil Loss Equation (USLE) and Geographical Information Systems are two spatial soil erosion analysis models because both have a spatial context. As an important factor, soil erodibility is crucial in determining soil erosion, with C-organic significantly influencing the K value. The main a...

The Influence of Organic and Inorganic Amendments on Phosphorus Chemistry in Two Acidic Soils of Southwestern Ghana

Oleh: Victor, Owusu-Gyimah, Klogo, Phanuel Yao, Gbefo, Francis

A study in southwestern Ghana compared the effects of organic and inorganic additives on P availability and related factors in two acidic soils, Ankasa and Abenia. Different amounts of P as KH2PO4 were applied: 0.067 g kg-1 for Abenia and 0.041 g kg-1 for Ankasa. Soil samples were treated with cow d...

Effect of Premium Compost on Soil Carbon Microbial Biomass in Pineapple Plants on Marginal Land Central Lampung

Oleh: Yusnaini, Sri, Aditya, Dinar, Ramadhani, Winih Sekaringtyas

Acidic soil reactions, low nutrient content, low organic carbon levels, and low soil biodiversity characterize marginal land. Adding organic matter, such as compost, is expected to rehabilitate these lands. One key biological indicator of successful land rehabilitation by adding organic matter or co...

Application of Rice-Husk Biochar to Coarse-Textured Ultisols and the Effects on Soil Fertility Indicators at Different Amendment-to-Sampling Intervals

Oleh: Ebido, Nancy Ekene, Awaogu, Chukwuebuka Ebuka, Akubue, Jacinta Chinonso

The low fertility status of the highly weathered tropical soils offers the opportunity to study the potential and optimum application rate of biochar as an organic soil amendment, especially for the dominant coarse-textured Ultisols. Despite the relatively fast mineralisation of organics in these so...

The Dynamics of Soil Organic Matter Fractions in Cacao-Based Agroforestry Systems

Oleh: Sari, Rika Ratna, Sapulete, Carla Leany, Saputra, Danny Dwi

Soil degradation is an important problem affecting crop production, especially in cocoa agroforestry systems, where soil health is crucial for optimal results. However, the effect of land management on changes in soil organic matter (SOM) content is often not visible through measurements of total so...
