Rice is a staple food for the Indonesian people and is a national strategic commodity for national food security. Rainfed area is a potential land to support national rice production, by improving soil management through balanced fertilization based on the soil characteristics. This study aims to determine the soil fertility and alternative management implemented in 2019 and 2020 in Sukaraja and Pondok Kelapa sub districts, Bengkulu Province. Soil fertility status for CEC, base saturation, C-organic, total P and total K taken based on the classification of the value of the combination of these chemical properties. The results showed that the soil fertility status of the rainfed rice fields in Sukaraja and Pondok Kelapa sub districts was low. The limiting factors for soil fertility for Sukaraja sub district are alkaline saturation, total K-total and P-total for Pondok Kelapa sub district. The limiting factors are all elements related to nutrient status assessment, namely CEC, base saturation, total P, total K and C-organic. Alternative soil management is carried out in an integrated manner by providing balanced organic and inorganic fertilizers. The provision of soil amendments such as straw compost, manure, biochar and agricultural lime/dolomite, especially for acid reacting soils, aims at increasing soil fertility before fertilization is applied.

ABSTRACTThis study aims to determine the effect of the location distance from the river bank and the depth ofsoil layer to the soil chemical properties in the tidal land area. The study was conducted in April untilJune 2016 in the tidal areas of Bajarum village, District of Kota Besi, East Kotawaringin, CentralBorneo Province. The study used survey methods and soil sampling in the field, analysis of soilsamples in the laboratory and continued with analysis and description of data. Soil sampling wasconducted at distances of 250, 500, 750, 1.000, 1.250 and 1.500 meters from the Mentaya river bankat two depth soil layers (0 - 25 cm and 25 - 50 cm). The soil chemistry properties analyzed includedpH, cation exchange capacity (CEC), base saturation, organic C, N total, total P2O5, total K2O,alumunium and hydrogen exchangeable and soil fertility status. The results of study showed that: (1)The further distance of soil from the position of Mentaya river bank there is an increase of organic C,total P2O5, total N, total K2O, pH, CEC, base saturation and soil fertility status, on the contraryshowed a decrease in alumunium and hydrogen exchangeable. The limiting factor of soil fertility ismainly the low base saturation, besides that at some point observation also due to low CEC, totalP2O5 and total K2O. (2) Sub soil layer (25 - 50) cm has a higher pH and base saturation valuescompared to topsoil layer (0 - 25) cm. In contrast, topsoil layer has CEC, alumunium and hydrogenexchangeable, total P2O5, total K2O, total N and organic C values higher than sub soil layer.Keywords: distance from river, tidal soil, soil chemical properties.

Soil Fertility Status

Soil fertility management in agricultural land is challenging in hilly areas of Nepal. The study assesses the soil fertility status of Bari (upland) and Khet (lowland) agriculture land in Mid-hill of Gorkha district. Altogether 30 samples were collected from soil surface (0 to 20 cm) by using hand shovel in January, 2017. The soil fertility parameters like pH, organic matter (OM), total nitrogen (TN), available phosphorus (P) and available potassium (K) were analyzed using standard methods in the laboratory of Central Department of Environmental Science, Tribhuvan University. Results revealed that an average pH in upland (6.62) was higher than the lowland (5.94). Similarly, OM (3.95%) and K (36.49 kgha-1) were relatively high in upland. In addition, pH, OM and available K were significantly varied at p<0.05 in upland and lowland soils, however, there is no significant difference in TN and available P. In addition, soil nutrient index showed that status of available K in both types of land is low, while OM and TN are medium soil quality in upland and lowland soil. The use of organic fertilizer and improved farming system can maintain and sustain soil fertility for crop growth and yield. Understanding distribution of soil nutrients in the study area might be useful for planners to make effective soil fertilizer management strategies.

Soil fertility is one of the most important factors influencing plant growth and productivity and it depends on the availability and quantity of nutrients in the soil. To study soil fertility status of an area, a study on soil chemistry and physics has to be conducted. The aim of this study was to investigate soil fertility status of smallholding Arabica coffee farms based on altitude and shades trees utilization. This research was carried out in April-August 2012 at IjenRaung highland areas by field survey. The results showed that the soil contained high content of organic carbon, nitrogen total, and C/N ratio; low available phosphorus; moderate to high cation exchange capacity, and low base cation of calcium, magnesium, and potassium; as well as slightly low pH. Higher altitude tended to have higher C organic and N total content, C/N ratio as well as pH. In contrast, in lower altitude tended to have lower available P, base saturation, as well as Ca, Mg, and K content. The dominant shade trees for coffee farming at the Ijen-Raung highland areas were suren (Toona sureni) , dadap (Erythrina sp.), kayumanis (Cinnamomum zeylanicum), pinus (Pinus mercusii), and kayu putih (Eucalyptus globulus). Different shade tree species resulted in different of soil fertility. Shade trees tended to influence cation exchange capacity from moderate to high, pH slightly acid, high base saturation, and low P available. Suren tree influenced better base cation than that of other trees but dadap tree was better in increasing soil fertility. Key word: Soil fertility, arabica coffee, andisol, shade trees, smallholding

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).

Soil Fertility Status

A study was conducted in the rice zone of Morang district to examine soil fertility status and the most limiting nutrient in the research area in accordance with rice cultivation requirements. Hundred samples were collected from two different locations of Ratuwamai Municipality ward number 6 and 8 at depth of 0-15 cm from surface soil. Samples were analyzed to find texture, pH, Nitrogen, Phosphorus, Potassium and Soil Organic Matter (SOM). Statistical tools were used to analyze the data. The most limiting nutrient in rice fields were determined by comparing the observed value with the standard requirement for rice fields. From analysis, it was revealed that, nitrogen content was found medium. Phosphorus was low in ward 6 whereas medium in ward 8. Potassium was high in ward 8 whereas medium in ward 6. SOM was low due to less application of organic fertilizer. Majority sample were of acidic probably due to more use of urea. Thirty percent samples of ward 8 were neutral and with equal alkalinity in both wards. Majority of sample was sandy loam except in ward 8 where ten percent sample was clayey loam. Both wards show equal behavior of loamy soil. Nutshell, majority of samples were of low fertility. Nitrogen and Potassium was most limiting as per the rice cultivation requirement with optimum soil pH. Various extension works regarding the importance of soil fertility management, sustainable soil management, optimum application of organic and inorganic fertilizers and the techniques to enhance the soil fertility status is required.

Soil Fertility Status

Abstract Reservoir tidal land used for agriculture is generally done when the reservoir water level begins to shrink. This land is used as a moor in dryland or lowland rice fields in the wetland. The purpose of the study was to determine the soil fertility status of the tidal land of the Tirtomarto reservoir, Central Java. Parameters tested include cation exchange capacity (CEC); base saturation (BS); C-Organic; total soil P and K levels according to the technical instructions for evaluating soil fertility. Soil samples were taken from three location points by the purposive sampling method. The results showed that most of the soil samples contained low to very low nutrients, except for the total P content which had a high value. Therefore, the fertility status in the tidal land of the Tirtomarto reservoir, Central Java, can be categorized as low. The low fertility status of the soil at the study site was due to the limiting factors, namely the low C-organic content of the soil, low K total soil, and low cation exchange capacity and base saturation.
