Abstract

Ultisols have considerable potential in developing agricultural cultivation, but in their management, they face several obstacles, including physical properties that do not adequately support plant growth. The low content of soil organic matter causes poor soil physical properties. Low organic matter content leads to low soil aggregate stability, obstructing pore distribution and infiltration so the soil can easily become compacted. This study aimed to observe the changes in some physical properties of the soil due to the application of cow manure and Gliricidia sepium pruning compost and its effect on the yield of soybean plants. This study used a randomized block design with five treatments, namely, K0 (without cow manure-Gliricidia compost), K1 (5 t ha-1cow manure-Gliricidia compost), K2 (10 t ha-1cow manure-Gliricidia compost), K3 (15 t ha-1cow manure-Gliricidia compost), and K4 (20 t ha-1cow manure-Gliricidia compost). The results showed that the 15 t ha-1 cow manure-Gliricidia compost was the best dose in improving the total pore space and penetration resistance of the soil studied. The application of 15 t ha-1cow manure-Gliricidia compost significantly increased soybean yield, reaching 2.97 t ha-1.

Abstract

The primary objective of this research was to investigate the efficacy of a combination of soil ameliorants, specifically oil palm shell biochar and tithonia compost, in enhancing the hydrological response of Ultisols and increasing corn yields. The study aimed to identify the optimal dosage combination that would significantly impact Ultisol hydrological response and maize yield. The randomized block design (RBD) was utilized to conduct the study. The ameliorant materials consisted of oil palm shell biochar and tithonia compost, which were divided into six treatments and four groups, including without Biochar and compost (p0), 10 tonnes/ha of Biochar (p1), 7.5 tonnes/ha of biochar 2.5 tonnes/ha of compost (p2), 5 tonnes/ha of biochar 5 tonnes/ha of compost (p3), 2.5 tonnes/ha of Biochar + 7.5 tonnes/ha (p4), and 10 tonnes/ha of compost (p5). Soil physical parameters, such as soil organic matter, soil bulk density, total pore space, soil texture, permeability, infiltration rate, and soil infiltration capacity, were monitored during the study. The BNJ test with a 95% confidence level was used to analyze the research data. The result of the study indicated that the p3 treatment (5 tonnes/ha of Biochar and 5 tonnes/ha of compost) and the p4 treatment (7.5 tonnes/ha of compost 2.5 tonnes/ha of Biochar) demonstrated a more significant improvement in infiltration rate and capacity, as well as soil permeability, compared to the other treatments. Moreover, the p3 treatment (5 tonnes/ha of biochar 5 tonnes/ha of compost) was shown to enhance corn yields by 80.53%, while the p4 treatment (2.5 tonnes/ha of biochar 7.5 tonnes/ha of compost) resulted in an 80% increase in yields.Keywords: Biochar; compost; infiltration; palm shells; tithonia; Ultisol

Abstract

Horticultural farming in Mudung Laut Village, Pelayangan Subdistrict, is the main livelihood of farmer groups in the area. Farming is carried out using conventional methods, and there is no proper waste management system in place, which has the potential to pollute the environment in the future. The objective of this PPM activity is to empower farming groups in zero-waste agriculture-based farming practices. The PPM activities include: 1) socialization of zero-waste agriculture-based farming practices, composting, biochar, and briquette production; 2) demonstrations and guidance on composting, biochar, and briquette production; 3) application of biochar and compost to farmers' fields; 4) evaluation of the activities. The results of this activity indicate that the knowledge and skills of farmers, particularly those in the Teman Abadi farming group, have increased through the provision of theory and practical experience in zero-waste agriculture, with the hope that farmers can utilize their agricultural waste to enhance the productivity of their farming operations.
