Organic carbon contributes to increasing soil productivity. In determining the soil fertility indicators, soil organic carbon mapping is required to provide information and demonstrate the distribution of organic carbon. In this study, remote sensing method testing was carried out by comparing data between observations in the field with rice productivity estimation data using Landsat 8 imagery. The observation was conducted on paddy fields with an area of about 4,800.86 ha in the volcanic region of Mount Talang. This research used a survey method with a grid system of 1,000 x 1,000 m intervals with a soil depth of 0-20 cm and 20-40 cm. The parameters of the soil observations carried out were bulk density, pH, and organic carbon. The results showed that Mount Talang volcanic rice fields had an estimated soil organic carbon stock of ±6,426.118 tons. A weak correlation was obtained between organic carbon and the estimated value of paddy rice productivity (r =0.024). Hence organic carbon in the study area could not be estimated with the value of lowland rice productivity.
有机碳有助于提高土壤生产力。在确定土壤肥力指标时，需要土壤有机碳制图来提供信息和展示有机碳的分布。在本研究中，通过将田间观测数据与利用Landsat 8图像估算的水稻产量数据进行比较，对遥感方法进行了验证。这次观测是在塔朗火山地区面积约为4,800.86公顷的水田上进行的。本研究采用网格系统的调查方法，网格系统间隔为1,000 x 1,000 m，土壤深度为0-20 cm和20-40 cm。土壤观测参数为容重、pH、有机碳。结果表明:塔朗山火山稻田土壤有机碳储量为±6426.118 t;有机碳与水稻产量估计值呈弱相关(r =0.024)。因此，研究区有机碳不能用低地水稻生产力值来估算。

High demand for shallots needs to be supported by an increase of yield in each region. The use of high-yield cultivar is one of the ways that can be done to increase the productivity of shallot conducted. Bangka has a soil of the Ultisol type, so adaptive cultivars on the land are indispensable. The research was carried out at the Experimental and Research Garden of Universitas Bangka Belitung. This study aims to determine the potential yield of onions and adaptive onion cultivars in Bangka Ultisol soil. The method used is a Randomized Block Design (RBD). Consists of 5 cultivars, such as Ambassador 1, Ambassador 2, Violetta, Keramat, and Maja Cipanas. Violetta is the most adaptive cultivar, that can grow to the height of the plant and the number of leaves that are almost equivalent to the onion plant planted in its native place. The onion cultivar that has the best yield potential to be grown in the Ultisol land of Bangka Regency is the Violetta cultivar because the weight of the bulbs and the number of bulbs produced are almost equivalent to the onion plants grown in their native area.

One of the activities of cultivating pakcoy (Brassica rapa L.) requires soil that has good fertility. One of the important soil fertility parameters for pakcoy plant growth is the availability of macro nutrients. Inceptisol is a soil that is quite extensive and has the potential to be developed but has problems in soil fertility. The purpose of this study was to determine the macronutrient status of inceptisol planted by pakcoy. The research was conducted in Kertanegla Village, Bojonggambir District, Tasikmalaya Regency, in January-February 2022. The method used in this study was a descriptive quantitative analysis of macro nutrients from soil analysis results. The results showed that the measured value for nitrogen was 0.1%, phosphorus value was 21.00 mg 100 g-1, and potassium was 41.00 mg 100 g-1. Based on these values, the macronutrient status at the study site, namely the nutrient status of nitrogen, was low, phosphorus was medium, and potassium was high.

Cukilan Village has a land area of 702.8 ha, with land use for agriculture covering an area of 620.2 ha. Agricultural land is widely used for fruit crops such as durian, rambutan and mango, but the production is considered not optimal, so it is necessary to evaluate the suitability of the land. This research was conducted to determine the characteristics of the Cukilan Village land; land suitability class for durian, rambutan and mango commodities; as well as land limiting factors. The research was carried out for 5 months and referred to the Technical Manual for Evaluation of Land Suitability for Agricultural Commodities with modifications to the determination of land suitability classes and limiting factors. The results of this study indicate that the land suitability class for durian and rambutan is moderately suitable (S2) with an area of 606.4 ha (97.8%) and marginally suitable (S3) with an area of 13.8 ha (2.2%). Land suitability class for mangoes is moderately suitable (S2). The limiting factors for durian, rambutan, and mango plants were rainfall, slope, drainage, KB, CEC, pH, and C-organic. Actions that can be taken to increase the productivity of these commodities are adding suitable organic matter, soil ameliorants such as lime and other materials containing CaCO3 and MgO3 and carrying out land management.

Analysis and prediction of land conversion using spatial-temporal data are essential for environmental monitoring and better land use planning and management. The West Sleman area has the potential to experience land use changes due to anthropogenic factors. This study aimed to determine the spatial-temporal dynamics of land use change in 2012-2022 and predict future land use change using the ANN-CA model for 20 years (2022-2042). Analyzed the spatial-temporal dynamics of land use change based on land use data derived from SPOT imagery, then predicted future land use change with the ANN-CA model using the MOLUSCE plugin on QGIS Desktop 2.18.11. The simulation results showed an accuracy of 86.66% and an overall Kappa value of 83% obtained by comparing the actual data in 2022 with the simulated data on land use change in the same year. The irrigated paddy fields decreased by 6.39% (685.22 ha) due to conversion to settlements. The area of residential buildings increased by 4.65% (498.49 ha) during 2012- 2017. Predictions of land use change in 2022-2042 show that the reduction of irrigated paddy fields will continue, and the number of residential buildings tend to increase.

Heavy metal pollution is an important issue that must receive serious attention from various authorities, including the community. Cadmium (Cd) contamination will harm environmental and human health. Upland rice plants are the main food-producing plants susceptible to Cd contamination. This study aimed to determine the effect of vermicompost on cadmium content and the vegetative phase of upland rice plants in Inceptisol. This study used a Completely Randomized Design (CRD) with one factor, namely several dose levels of vermicompost, namely 0, 5, 10, 15, 20, and 25 t ha-1. The results of this study indicated that the use of vermicompost significantly affected the number of leaves and tillers of upland rice. A Vermicompost dose of 15 t ha-1 is considered optimum in increasing the number of leaves and tillers of upland rice. The use of vermicompost increased the vegetative growth of upland rice, so it increased the productivity of upland rice plants.

Rice is one of the food crops and commercial crops. Rice also has the potential to contribute significantly to increasing income and employment in rural areas. As indicated by rice imports from Thailand and Vietnam, national rice production has not been able to meet domestic demand. The objectives of this study were (1) to determine the actual and potential land suitability levels of rice plants in Luwu Regency and (2) to find out the limiting factors for actual and potential land suitability of rice plants in Luwu Regency. Evaluation of rice land suitability using the FAO method. Based on the limiting factors of land characteristics. The results showed that the actual land suitability of plants was marginal (S3fn) with the limiting factors for nutrient retention (organic C) and available nutrients (P2O5 and K2O). Efforts to improve the limiting factor can be made by adding 59.6 t organic matter ha-1, 332.6 kg P2O5 ha-1, and 98 kg K2O ha-1 so that the actual land suitability of marginal (S3) becomes very suitable (S1).
水稻是粮食作物和经济作物之一。大米也有潜力为增加农村地区的收入和就业作出重大贡献。从泰国和越南的大米进口情况可以看出，国内大米生产无法满足国内需求。本研究的目的是:(1)确定鲁武县水稻植物的实际和潜在土地适宜性水平;(2)找出鲁武县水稻植物的实际和潜在土地适宜性的限制因素。利用FAO方法评价水稻土地适宜性。基于土地特征的限制因素。结果表明，植物的实际土地适宜性为边际(S3fn)，限制因子为养分保留(有机C)和速效养分(P2O5和K2O)。通过添加59.6 t有机质ha-1、332.6 kg P2O5 ha-1、98 kg K2O ha-1来提高限制因子，使边际(S3)的实际土地适宜性变得非常适宜(S1)。

The medium type, with a total area of 3,683.285 ha, is spread over land units with podzolic soil types. Heavy type with a total area of 1,458.367 ha and the whole area is spread over land units with podzolic and Litosol soil types. The erosion hazard level is very heavy, with a total area of 421.97 ha and is spread over land units with Podzolic and Litosol soil types.","PeriodicalId":413872,"journal":{"name":"Jurnal Tanah dan Sumberdaya Lahan","volume":"39 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114127066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high demand for mustard greens from consumers in Sidoarjo has forced farmers to increase their production. One of the efforts made is to provide excessive N, P, and K fertilizers. This study aimed to analyze the effect of the combined application of goat manure and N, P, K on growth, yield, P uptake, and soil chemical properties. Six treatments and three replications arranged in a randomized block design. The results showed that the combination of goat manure and N, P, K fertilizer had a significant effect (p<0.05) on plant height, number of leaves, plant fresh weight, total plant P, soil pH, soil organic C, soil total N, soil C/N ratio, and soil total P, but not significantly different (p>0.05) on plant dry weight, P absorption, and available P of the soil. The combination of goat manure and N, P, K fertilizer increased plant height from 36.4 cm to 50 cm (+37.4%), number of leaves from 18 to 43 leaves (+143.8%), fresh weight from 92 g to 310 g (+237%), dry weight from 10.8 g to 14.1 g (+30.6%), total crop P from 1.4% to 1.45% (+3.6%), P uptake from 15.1 g to 20.5 g (+35.2%), organic C from 0.97% to 1.25% (+28, 9%), total N from 0.35% to 0.42% (+20%), C/N ratio from 2.77 to 2.97 (+7.2%), total P from 18.9 mg 100 g-1 to 36.6 mg 100 g-1 (+26.6%), and available P from 4.22 ppm to 6.24 ppm (+49.9%).
