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

Changing of Sandy Soil Chemical Properties with Azolla microphylla and Quail Manure
Syamsiah, Jauhari, Herawati, Aktavia, Mujiyo, Mujiyo
Uncontrolled land conversion causes reduced land area for plant cultivation. The alternative used for rice cultivation is the marginal land such as sandy soil, however, several constraints led to very low productivity, so it needs proper management such as the addition of organic matter. The purpose...

Effect Application of Cellulolytic Bacteria Consortium And Palm Kernel Ash on Red Chili Plants in Peat Soil
gusmawartati, gusmawartati gusmawartati, Zulfatri, Zulfatri, Nabila, Nabila
Limited agricultural land in Indonesia makes peatland an alternative land for agricultural intensification. Peat soil has a low fertility, so applying cellulolytic bacteria and palm oil shoot ash is recommended. This study aimed to determine the effect of cellulolytic bacteria consortium and oil pal...

The Influence of Compost and Biochar on the Physico-Chemical Properties of Soil and the Growth of Tomatoes in Sub-Optimal Land
Endriani, Endriani, Sa’ad, Asmadi, Listyarini, Diah
This study seeks to evaluate the effectiveness of coconut shell biochar (CB)  and/or Leucaena compost (LC) as ameliorants in improving soil chemical and physical properties, as well as enhancing tomato yields. The goal is to identify the most effective combination of ameliorant formulations that ...

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

Spatial Distribution of Soil Properties and Soil Fertility Status in the Paddy Rice Field of Oransbari
Hastuti, Irena Tri, Djuuna, Irnanda Aiko Fifi, Baan, Samen
Soil properties and soil fertility status of paddy rice fields are considered important factors related to the yield and production of rice; therefore it is essential to understand those properties across the farm.  The objectives of this research is to quantify the soil properties and soil ferti...

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

Study of the Quality of Biogeotextile Materials as Semi-Organic Mulch on Saline Land
Wijayanti, Fitri, Maroeto, Maroeto, Lestari, Safira Riska
Degraded land affects almost all ecosystems and can harm the progress and quality of human life, so it needs attention. Saline soil is a land degradation with high salt content that causes toxic effects, increases root osmotic pressure, and inhibits plant growth. One solution is using organic mulch ...

Water Table Control Model for Maize Cultivation of C Typology Land on Tidal Lowland Reclaimed Area of South Sumatra, Indonesia
Imanudin, Momon Sodik, Madjid, Abdul, Bakri, Bakri
Tidal lowland productivity in type C is still low. Most of them have only been able to cultivate rice twice a year. The third cultivation of corn often fails due to a lack of water. The research objective is to determine an operational model for water management in the field for maize cultivation at...

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