Soil fertility status and land suitability evaluation for rice crops on former shrimp ponds

Undertaking suitable land, including former shrimp ponds for rice, is required to cope with future rice shortages. The purpose of this study was to identify the soil morphology and physicochemical properties, determine soil fertility status and assess irrigated rice suitability of ex-shrimp ponds. Soil morpho-physicochemical properties such as soil color, structure, texture, pH, organic-C, P2O5, K2O, base saturation, and cation exchange capacity were determined. The resulting data was then matched into the criteria for BSCR and SLAN/CCDS, five major soil fertility criteria, and ICALRRD land suitability. Soil physiographical, morphological, and physicochemical analysis suggested that the soil developed from the alluvial site of calcareous-marl parent material located at saturated backswamp, then permanently drained. ESP, SAR, and salinity values were detected relatively lower than saline, sodic, and saline-sodic soil. The entire cations fell below BCSR ideal ratios, whereas all exchangeable K were detected below the CCDS/SLAN thresholds. Actual suitability for land units of A, B, and C were S3-rc,na, S3-na and S3-rc,nr,na,eh, respectively. The improvement such as fertilization, amelioration, slope flattening/cut-filling, and irrigation management increases all land units to S1. This study pinpointed the importance of former shrimp pond soil to provide suitable land for rice crop cultivation. Also, encouraging further research to identify the origin of alluvial parent material from the soil at the study site

Assessing soil fertility status and land suitability for patchouli plants (Pogostemon cablin Benth.) in Lamala District, Banggai Regency

Besides influenced by genotype, the quality and quantity of patchouli essential oil were controlled by soil as a growing medium. The development of patchouli plantation in Lamala District is still hampered by negative stigma from the community. It is believed, the strong absorption rate from patchouli could lead to soil nutrient deficiency. The purpose of this study was to determine soil fertility status and evaluate its suitability for patchouli plant in 3 land units (e.g., uncultivated, cultivated with fertilization, and cultivated without fertilization). The method used is an Exploratory-Descriptive Survey. The determination of soil properties was based on physical properties such as texture, and chemical properties such as pH, organic-C and nitrogen, P2O5 and K2O, base cations and cation exchange capacity/CEC, and Fe. The data then matched to Soil Fertility and Land Suitability Criteria for the patchouli plant. The result showed that the chemical properties in 3 land units had slightly acidic, high CEC, medium base saturation, moderate P2O5 content, and moderate organic-C content. Meanwhile, the K2O content of the land without patchouli was very low and the patchouli with and without fertilizer was low. Soil fertility status in 3 land units was classified as marginally suitable (S3-rc,na), this is due to the limiting factors; soil texture (rc) and P2O5 (na).

Combination of NPK fertilizer with bokashi rice straw on growth and yield of Cisantana rice varieties

One of the cultivation technologies that need to be considered in increasing rice production is the proper use of fertilizer. This study is to find out the substitution of NPK fertilizer with rice straw bokashi to the growth and yield of rice paddy plants cisantana varieties. This research was conducted from August to November 2020 in Samaku Village, Bualemo District, Banggai Regency. The method used is a RandomIzed Design Group (RAK) factorial pattern consisting of 2 factors, namely factor A (NPK fertilizer) and factor B (Straw Bokashi). The combination of NPK fertilizer and rice straw bokashi has no natural effect on rice paddy plants of Cisantana varieties. Still, it has a natural impact on grain dry weight per plot. The treatment of rice straw bokashi independently has a noticeable effect on the height of the plant, the number of saples, the number of productive saples and the length of the panic. The bokashi straw rice dose of 75% (3.75 tons/ha) is the best dose for high plant growth, number of saples, number of productive saples and malai length. While the dose of 75% NPK (187.5 kg/ha) + 75% bokashi rice straw (3.75 tons/ha) is the best combination dose for varied dry weight of grain per plot.

The Addition Effectiveness of Sweat Potato Prebiotics on Digestibility and Bacteria In Vitro

Pakan merupakan biaya terbesar dalam produksi peternakan. Pakan yang mengandung antibiotik sudah dilarang penggunaanya karena menimbulkan residu pada ternak sehingga dapat mengganggu kesehatan manusia. Solusi untuk mengganti penggunaan antibiotik adalah dengan penggunaan prebiotik. Salah satu sumber prebiotik adalah ubi jalar. Potensi ubi jalar sebagai sumber prebiotik karena adanya senyawa rafinosa dan meltotriosa. Oligosakarida berupa rafinosa pada ubi jalar merupakan sumber makanan bagi probiotik, karena di dalam usus rafinosa tidak diserap sehingga mikroba berperan dalam mencerna gugus gula rafinosa. Selain itu, produksi ubi jalar juga sangat melimpah di Indonesia. Penelitian ini bertujuan untuk menguji efektivitas pemberian prebiotik ubi jalar merah, putih dan ungu dengan menggunakan cairan rumen untuk melihat kecernaan bahan kering, bahan organik, VFA total dan total bakteri secara in vitro. Metode penelitian dilakukan dengan cara in vitro dan koloni bakteri dihitung dengan metode pencacahan koloni bakteri hidup dengan 4 perlakuan dan 3 kali ulangan. Berdasarkan hasil penelitian ini disimpulkan bahwa ubi putih merupakan sumber prebiotik yang paling baik digunakan, karena pada ubi putih jumlah koloni bakteri probiotik yang tumbuh lebih tinggi dibandingkan ubi merah, ungu, dan ransum kontrol.
