Abstract

Regosol has low fertility, especially carbon (C), nitrogen (N), phosphorus (P), potassium (K) and other macro elements, but it can be potential for agriculture cultivation. Addition of straw compost and tithonia granule (Kojeto granule) with clay binder can improve chemical soil fertility. This study aimed to determine the composition of the Kojeto granule with a clay binder and to define the interaction between type of Kojeto granule and dosage of compost granule in the chemical characteristics of Regosol. This research was conducted in a wirehouse and soil laboratory, Andalas University. The experiment used a completely randomized factorial design, with two factors and three replications. The first factor was the ratio between compost composition and clay binder 9:1 and 8:2. The second factor was 4 levels of granule compost doses (0; 7,5; 15; 22,5 t ha-1). The results showed that the best composition ratio between Kojeto and clay binder on chemical properties was 9:1. The type of Kojeto 8:2 and dosage (22 t ha-1) had an interaction on Ca-dd (3.75 me 100 g-1). The single effect on the type compost granule at type 9:1 was parameter C-org (2.23%), and single effect on increasing the dosage of granule compost at a dose of 15 t ha-1 was C-org (2.30%), N-tot (0.27%), P-available (14,30 ppm), pH (5,80), and K-dd (0.62 me 100 g-1). The optimal recommended dose is 15 t ha-1.

Abstract

Differences in tree age and cropping systems may influence the microbial diversity, including fungal species and population. The purpose of this study was to determine the diversity, of species and population of arbuscular mycorrhiza spores and the relationship between the number of arbuscular mycorrhiza spores and the soil chemical properties in different pine age group and coffee as an intercropping system at sloped areas. The study was conducted from April to July 2017. The study used a survey method with 5 age groups (KU) and three replications. The study was divided into 3 stages: 1). collection of soil and root samples, as well as measuring plot characteristics (i.e. basal area, canopy cover, standing litter mass); 2). Measurement of Mycorrhizal in the laboratory (spore extraction, spore identification, root colony percentage analysis); 3). Soil Chemical Analysis (pH, total P, available P). All data was tabulated, and tested using ANOVA with Randomized Block Design. If there is a significantly different, a further LSD test is performed with a level of 5%. Correlation and regression tests were performed to determine the relationship between parameters. The results showed that there were significant differences in the parameters of canopy density, number of genus spores of Acaulospora 100 g-1 soil, Soil pH, and total P in the soil. However, the study was unable to detect significant differences in, other parameters, such as root infection, number population of Glomus and Gigaspore, available P, etc.. The correlation test showed that the increase in the age group of the coffee intercropping system did not correlate with the number of arbuscular mycorrhizae in each plot observed. The number of Arbuscular Mycorrhizal Spores in each age group of intercropping pine did not correlate with the soil's chemical properties (pH, P-Total, P-Available).

Abstract

Peat land has an important role, function, and benefit for human life, biodiversity, and global climate. The peat swamp forest in Central Kalimantan was devastated to a very large extent, which addresses the restoration of peat swamp forests, has changed the characteristics of peat which contain physical, chemical, and biological characteristics. Peat recovery efforts carried out at the KHDTK Tumbang Nusa consist of natural succession and revegetation. The study aimed to analyze the chemical properties of peat soils in different types of post-fire forest protection and to assess the spatial variability of peat chemical properties in Forest Areas for Special Purposes (KHDTK) Tumbang Nusa, Desa Tumbang Nusa, Jabiren Raya District, Pulang Pisau Regency. The research plot consisted of forest restoration efforts, namely secondary forest, revegetation, and natural regeneration. Variable measured consisted of pH, total organic C, CEC, N, P, K, exchangeable K, Na, Ca, Mg, as well as ash content and water content. The results showed that secondary forest treatment was the best peat swamp forest restoration technique. Spatial variability sub-plots and sample points did not significantly affect the differences in chemical properties of the peat, but the differences in chemical properties of peat is the peat swamp forest was determined by restoration technique.
