Soil degradation to support the growth and development of plants and produce goods and services has become a global concern. To support government programs and efforts to improve land, the role and cooperation of researchers with local governments should be increased to multiply, and information related to the potential of soil degradation can be used as supporting data for development planning in an area. The potential and status of soil degradation in the region of East Kutai Regency, are still relatively low. But it has a high potential for damage because land use more increasing for various purposes. Soils in East Kalimantan is dominated by old soil, such as Podsolic or Ultisols, easily damaged if utilized without regard to principles of conservation. Especially for soil in Rantau Pulung there is a parameter with exceeded status of standard quality, i.e. permeability; then in Batu Ampar found four parameters, namely permeability, the composition of soil fraction, bulk density and soil pH, next to Long Masangat founded two parameters, namely bulk density and permeability. The more of limiting factors, then in the land use should also apply and demand high conservation treatment to maintain the land or soil quality.

The main commodity of food crops cultivated in Indonesia is rice, but rice productivity in Indonesia has decreased. Factors that cause a decrease in rice productivity are land conversion that continues to increase and unbalanced fertilization. Efforts to increase rice yields are by applying a combination of inorganic fertilizers and biological fertilizers. Otherwise, this study focused on studying the effect of the application of a combination of inorganic fertilizers and biological fertilizers on several soil chemical characteristics and rice production in the experimental field of the Faculty of Agriculture, Jatimulyo District, Malang City. Application of biological and inorganic fertilizers with analysys of variance (ANOVA) showed a significant effect on chemical characteristics parameters such as pH and available P. Otherwise, this research showed a significant effect on production, such as the weight of biomass and milled dry grain harvested. Based on this research, the best combination fertilizer is T3 (75% basal inorganic fertilizer + 100% biological fertilizer).

Land use in Bogor Regency has diverse vegetation and different soil characteristics. Soil characteristics have an influence on land management. Improper land management has led to a decrease in microbial populations, biodiversity and a decline in soil quality and fertility. Soil fertility is produced by the interaction of the physical, chemical, and biological properties of the soil. This study aims to determine the correlation of soil biological and chemical properties in several different types of land use in Bogor Regency. Soil sampling was carried out using the purposive random sampling method with five replicates. Soil samples were taken at a depth of 0-20 cm by ±1 kg. The research site includes eight land uses namely bamboo gardens, sengon gardens, lamtorogung gardens, and dragon fruit orchards. The results of the analysis showed that the dragon fruit field had an acid pH with very high organic C and total N levels with the highest fungal population of 2.27 x 105 CFU g-1. Meanwhile, bamboo fields with an acid pH also have a medium organic C content and low total N with the lowest total fungi population of 0.37 x 105 CFU g-1. Azotobacter populations and respiration values had the highest correlation with the total P content of the soil. The correlation value of the total population of fungi was the highest, with a total N levels of 0.427.

Rice production in Pamekasan Regency from 2011 to 2019 decreased by 38.71% due to farmers applying fertilizers that did not match plant needs, such as insufficient application of manure, organic fertilizers and other inorganic fertilizers. In addition, the basic fertilization obtained by farmers comes from informal information, so the application of fertilizers on the land is not efficient. Efforts have been made to overcome these problems by evaluating soil fertility from the aspect of nutrient retention as a basis for determining fertilizer requirements. The purpose of this study was to evaluate soil fertility, especially from the aspect of nutrient retention in paddy fields in Pamekasan Regency. This research used a purposive random sampling method based on SPL (Land Map Unit). Parameters observed were cation exchange capacity, organic C, base saturation, pH, electrical conductivity, texture, porosity, bulk density and saturated hydraulic conductivity. The results showed that the high level of soil fertility in Pamekasan Regency was found in cation exchange capacity in Tlanakan District (43.92 cmol kg-1), base saturation in Galis District (99.38%), pH in Tlanakan District (7.00), electrical conductivity in Pakong and Pasean districts (0.39 mS) and the dominant texture is the clay fraction. Low fertility levels are found in soil organic C in Waru and Kadur Districts (0.08%), bulk density in Pasean District (1.59 g cm-3), porosity in Proppo District (34.89%), and saturated hydraulic conductivity in Pasean District (46.34 cm hour-1).
2011年至2019年，帕梅卡桑县的水稻产量下降了38.71%，原因是农民施用的肥料与植物需求不匹配，例如粪肥、有机肥和其他无机肥料的施用不足。此外，农民获得的基本肥料来自非正式信息，因此在土地上施用肥料效率不高。为了克服这些问题，人们从养分保持方面评价土壤肥力，作为确定肥料需要量的基础。本研究的目的是从土壤肥力的角度，特别是从水田养分保持的角度来评价帕梅卡桑县的土壤肥力。本研究采用基于SPL (Land Map Unit)的有目的随机抽样方法。观察的参数包括阳离子交换容量、有机碳、碱饱和度、pH、电导率、织构、孔隙率、容重和饱和水力导率。结果表明:帕梅卡山县土壤肥力水平较高，其中阳离子交换容量为43.92 cmol kg-1，碱基饱和度为99.38%，pH值为7.00，电导率为0.39 mS，主要质地为粘土组分。Waru和Kadur地区土壤有机碳肥力水平低(0.08%)，pasan地区土壤容重低(1.59 g cm-3)， Proppo地区土壤孔隙度低(34.89%)，pasan地区土壤饱和导水率低(46.34 cm h -1)。

Soil respiration activity is one of the contributors to carbon dioxide (CO2) emissions from the agricultural sector. The agricultural sector can also reduce the CO2 emissions it produces, one of which is by making biochar from agricultural waste. Palm shells have potential as raw materials for biochar because they contain hemicellulose, cellulose and lignin. The purpose of this study was to study the effect of adding biochar with variations in pyrolysis temperature on CO2 emissions resulting from the soil respiration process. Palm shell biochar was pyrolyzed with temperature variations of 500 oC and 600 oC for 1 hour and activated using NaOH. Biochar was then added to the soil at a dose of 10% and incubated for 25 days which was tested once every five days. The results showed that the highest CO2 emissions occurred from soil respiration activities with the addition of palm shell biochar at a temperature of 600 oC at an incubation time of 5 days, which was 37 mg CO2. This value was 22.95% greater than the control treatment without the addition of biochar.

Palm shell biochar was pyrolyzed with temperature variations of 500 oC and 600 oC for 1 hour and activated using NaOH. Biochar was then added to the soil at a dose of 10% and incubated for 25 days which was tested once every five days. The results showed that the highest CO2 emissions occurred from soil respiration activities with the addition of palm shell biochar at a temperature of 600 oC at an incubation time of 5 days, which was 37 mg CO2. This value was 22.95% greater than the control treatment without the addition of biochar.","PeriodicalId":413872,"journal":{"name":"Jurnal Tanah dan Sumberdaya Lahan","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126430195","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}

Drought is one of the most significant impacts of the climate on agriculture, especially food crops. Standardized Precipitation Index (SPI) is an Index for droughts. The research objective was to study the relationship of SPI values to the productivity of rice and corn crops in the Situbondo district. The result showed that the value of the SPI time scale at three months is the most appropriate for the observed productivity of rice and corn. The SPI value significantly correlated with the productivity of rice plants in the Jatibanteng and Arjasa districts but did not significantly affect the productivity of corn in the Mlandingan and Situbondo districts. Furthermore, the El-Nino phenomenon reduced the rice productivity up to 3.9% and the corn productivity up to 48.1%. The La-Nina phenomenon reduced rice productivity up to 26.0% but increased the productivity of corn up to 81.7%.
