Abstract

Different soil types have varying soil fertility potentials, which contribute to the crop yields obtained. The aim of this study is to analyze the characteristics of soil pH, organic carbon (C-Organic), and cation exchange capacity (CEC) and to determine appropriate management practices for corn cultivation on two different soil types in Unit Pemukiman Wuna Village, Tongkuno District. The method used in this study was a free survey method utilizing minipits for each soil type. Soil sampling was conducted using a composite method, where soil samples were taken from three points for each soil type at depths of 0–30 cm (topsoil) and 30–60 cm (subsoil). The soil from each layer was then composited, and approximately ±1 kg of soil was taken for laboratory analysis to determine its pH, Organic-C, and CEC levels. The results showed that the chemical properties of soil type 1 (Alfisol) had a lower pH than soil type 2 (Mollisol), with values of 5.02 and 5.24, respectively. Similarly, the CEC analysis indicated that soil type 1 had a lower CEC compared to soil type 2, with values of 5.16 and 5.20 me/100 g, respectively. However, in terms of soil organic carbon content, the analysis revealed that the Organic-C level in Alfisol was higher than in Mollisol, with values of 5.66% and 3.47%, respectively. Appropriate management practices for corn cultivation require efforts to increase soil pH and CEC through liming and zeolite application. Additionally, to maintain pH, C-Organic, and CEC levels, blanket herbicide application should be avoided, and excessive use of chemical fertilizers should be minimized to sustain soil health and land sustainability

Abstract

The purpose of this study was to determine the effect of feeding bokashi cow manure on the chemical properties of Alfisols soil and the yield of Muna's local corn (Zea Mays L.). This study was conducted at the Land Experiment Garden II Faculty of Agriculture of Halu Oleo University, and the sampling of Alfisol soil was conducted in Puwatu Village, from March to June 2022. This study used a Randomized Group Design (RGD) method with 4 bokashi cow manure treatments: B0 = without bokashi cow manure (control), B1 = 200 g polybag-1, B2 = 400 g polybag-1, B3 = 600 g polybag-1. The research results show that the treatment of bokashi manure improves the chemical properties of the soil. Treatment of B3 gives the highest values for organic-C (0.34%), total-N (0.11%), available-P (25.66 ppm), KTK (53.19 me/100g) except for available-K and affects plant height, stem diameter, fruit weight and seed count.

Abstract

This study aims to understand the effects of biocharcoal and manure interactions on pH, CEC, C, K soils and the growth and production of red pepper plants on ultisol soils and to understand the independent effects of biocharcoal charcoal and chicken manure on pH, CEC K, C, K soils and growth and production The red chili pepper plant in the soil of the ultisol. This study used the Randomized Group Design (RDB) in factorial patterns. The first factor, Biocharanganese consists of three levels: B0 = without the addition of biocharangium B1 = 300 g polybag-1 B2 = 600 g polybag-1 The second factor is that chicken manure consists of 3 levels, namely A0= without giving chicken manure, A1=100g polybag-1, A2=200g polybag-1. Research results show that the delivery of biocharcoal and chicken manure can improve the chemical properties of pH, CEC, organic-c except available-k are available and have no effect on the growth and production of red chili peppers while for the growth and production of red chili peppers only self-supplying chicken manure has a better effect on the plant height, number of branches, number of fruit and weight at 200 g of polybag-1 (A2).Keywords: soil chemistry, charcoal biocharcoal, chicken manure, red pepper, Ultisol
