The Impact

<p>The impact of aquaculture activities has led to environmental degradation, especially ponds bottom soil quality. The purpose of this study was to assess the status of the ponds bottom soil quality in different aquaculture systems (traditional and intensive) in BLUPPB Karawang region in a flexible value of soil quality index (SQI). Twenty ponds consisting of 5 traditional of milkfish (<em>Chanos chanos</em>) juvenile rearing ponds and 5 traditional polyculture ponds, 5 intensive of <em>Litopenaeus </em><em>va</em><em>n</em><em>namei</em> shrimp ponds lined with plastic mulch and 5 intensive <em>L. vannamei </em>shrimp earthen ponds. Variables of soil quality parameters examined include physical, chemical and biological of pond bottom soil. Sediment ponds with a depth of 5-10 cm were taken for analysis. Data statistically analyzed using Anova, continued with pos hoc test HSD Tukey. The results showed the ponds soil quality (SQI) of BLUPPB Karawang area has an average of 0.38 ± 0.02 or included in low criteria. Aquaculture systems were not significant (p&gt; 5%) to the general status of ponds soil quality. Aquaculture systems (intensive and traditional) only gave a significant different (p&lt;5%) to the parameter of soil bulk density, c-organic, total N, C:N ratio, total S, total P and soil respiration. Stability of the ponds bottom soil chemical compositions over time make level of intensity does not significantly affect, beside routine sediment removal at the end of cycle in intensive culture.</p>

The Impact

AbstractDesert steppe soil security issues have been the focus of attention. Therefore, to understand the impact of industrial activities on the soil quality of desert grasslands, this experiment investigated the Gaoshawo Industrial Concentration Zone in Yanchi County. Based on the distance and direction from the industrial park, sample plots were established at intervals of 1–2 km. A total of 82 surface soil samples (0–20 cm) representing different pollution sources were collected. The samples were analysed for pH, total nitrogen, total phosphorus, available phosphorus, available potassium, organic matter, copper (Cu), cadmium (Cd), chromium (Cr), lead (Pb), and zinc (Zn). The desert steppe soil quality was analysed based on the integrated fertility index (IFI) and the Nemerow pollution index (PN), followed by the calculation of the comprehensive soil quality index (SQI), which considers the most suitable soil quality indicators through a geostatistical model. The results showed that the IFI was 0.393, indicating that the soil fertility was relatively poor. Excluding the available potassium, the nugget coefficients of the fertility indicators were less than 25% and showed strong spatial autocorrelation. The average values of Cu, Cd, Cr, Pb and Zn were 21.64 ± 3.26, 0.18 ± 0.02, 44.99 ± 21.23, 87.18 ± 25.84, and 86.63 ± 24.98 mg·kg−1, respectively; the nugget coefficients of Cr, Pb and Zn were 30.79–47.35%. Pb was the main element causing heavy metal pollution in the study area. Higher PN values were concentrated north of the highway in the study area, resulting in lower soil quality in the northern region and a trend of decreasing soil quality from south to north. The results of this research showed that the average SQI was 0.351 and the soil quality was extremely low. Thus, industrial activities and transportation activities in the Gaoshawo Industrial Zone significantly impact the desert steppe soil quality index.

Ecologically fragile cropland soils and intensive agricultural production are characteristic of the valley area of the Tibetan Plateau. A systematic assessment of soil quality is necessary and important for improving sustainable cropland management in this area. This study aims to establish a minimum data set (MDS) for soil quality assessment and generate an integrated soil quality index for sustainable cropland management in the Tibetan Plateau. Soil samples were collected from the 0–20 cm depths of agricultural land in the middle and lower reaches of the Lhasa River. These samples were analyzed by routine laboratory methods. Significant differences were identified via statistical test between different soil types and land use types for each soil property. Principal component analysis was used to define a MDS of indicators that determine soil quality. Consequently, effective porosity, pH, total organic C, total N, available P, and catalase were identified as the final MDS. The soil quality index was obtained by the fuzzy-set membership function and the linear weighted additive method. The soil quality index differed significantly between the soil types and land use types. The soil quality can be ranked based on their indices in the following order: 1. Grain land with meadow soils, 2. Grain land with steppe soils, 3. Greenhouse vegetable land with fluvo-aquic soils, 4. Grain land with fluvo-aquic soils. The soils with higher soil quality indices exhibited better soil structure, higher nutrient contents, and superior resistance to water and nutrient loss. While the intensive tillage practices associated with vegetable production could reduce the values for effective porosity, pH and catalase, the application of appropriate fertilizers increased the values for total organic C, total N and available P. Therefore, the MDS method is an effective and useful tool to identify the key soil properties for assessing soil quality, and provides guidance on adaptive cropland management to a variety of soil types and land use types.

Determination of soil quality in Giriwoyo Sub-district, Wonogiri Regency, will generate a Soil Quality Index which can be used as a reference for soil cultivation for optimal productivity. This research was a descriptive exploratory with a survey approach. The survey area consisted of 12 land mapping units (LMU) with 3 replications for each LMU. Determination of LMU based on soil type, land use, slope and rainfall. The parameters used were BD (bulk density), porosity, organic C, pH, CEC (cation exchange capacity), BS (base saturation), available P, available K, total N, and MBC (microbial biomass carbon) that represented the physical, chemical and biological properties of the soil. Principal Component Analysis (PCA) analysis was performed to obtain the Minimum Data Set (MDS). The Soil Quality Index (SQI) at each LMU was calculated by multiplying the PCA result score (Wi) with the score for each selected indicator (Si). The result showed that the Soil Quality Index at each LMU was low. The highest Soil Quality Index was found in fields land use with an SQI of 0.34. The soil indicator that limited the soil quality was available P.

Kebakaran lahan gambut menyebabkan terjadinya perubahan sifat fisika, kimia dan biologi tanah gambut sehingga secara otomatis mempengaruhi kualitas tanah yang dinyatakan dengan Indeks Kualitas Tanah (IKT). Tujuan penelitian ini adalah menentukan indeks kualitas tanah dan faktor penentunya pada lahan gambut terbakar (GT) dan tidak terbakar (GTT). Penelitian dilakukan di Kelurahan Bansir Darat Kecamatan Pontianak Tenggara Kota Pontianak pada GTT  dan GT. Tahapan penelitian meliputi pengambilan sampel tanah pada masing-masing lahan, pengamatan dan pengukuran kedalaman gambut, ketebalan lapisan gambut dan kematangan gambut serta perhitungan jumlah cacing. Analisis sifat fisika tanah meliputi bobot isi, kadar air kapasitas lapang, porositas total; sifat kimia tanah terdiri dari reaksi tanah (pH), karbon organik (C-organik), Nitrogen total (N-total), rasio CN, posfor tersedia (P-tersedia), natrium, kalium, kalsium dan magnesium dapat dipertukarkan (Na-dd, K-dd, Ca-dd dan Mg-dd), kapasitas tukar kation (KTK), kejenuhan basa (KB), kadar abu; dan jumlah cacing tanah untuk sifat biologi tanah. Hasil penelitian menunjukkan GT dengan kematangan saprik memiliki kedalaman gambut lebih dangkal dibandingkan GTT dengan kematangan hemik. Kadar air dan porositas pada GT juga lebih rendah dibandingkan GTT. Kation basa GT lebih tinggi dibandingkan GTT meskipun kriteria keduanya sangat rendah. Parameter penentu kualitas tanah yaitu C-organik, CN rasio, N-total, P-tersedia, kalsium, natrium, kalium, kejenuhan basa, bobot isi, kadar air dan porositas. Kedua lahan memiliki kriteria IKT rendah namun GT memiliki nilai yang lebih tinggi (0,34) daripada GTT (0,27). Meskipun nilai IKT pada GT lebih tinggi, banyak dampak negatif yang ditimbulkan dari pembakaran lahan gambut. Karena itu pemerintah melarang pembakaran lahan dengan mengeluarkan kebijakan-kebijakan tentang pelarangan pembakaran hutan dan lahan gambut.AbstractPeatland fires cause changes in the physical, chemical and biological characteristics of the peat soil. It automatically affects the quality of the soil as stated by the Soil Quality Index (IKT). The purpose of this study was to determine the soil quality index and its determinants in burnt (GT) and unburnt (GTT) peatlands. The research was conducted in Bansir Darat Village, Southeast Pontianak District, Pontianak City on GT and GTT. The research stages included taking soil samples from each land, observing and measuring the depth of the peat, the thickness of the peat layer, the maturity of the peat and counting the number of worms as well. Analysis of soil physical characteristics including bulk density, moisture content of field capacity, total porosity; soil chemistry consists of C-organic, total nitrogen (N-total), CN ratio, available phosphorus (P-available), exchangeable sodium (Na-dd), potassium (K-dd), calcium-dd (Ca-dd)dan magnesium (Mg-dd), cation exchange capacity (CEC), base saturation (KB), content of ash; and the number of earth worms for soil biology property. The results showed that the physical characteristics of peat on GT had a shallower peat depth with sapric compared to GTT with hemic. The water content and porosity on GT are lower than GTT as well. The base cation of GT is higher than GTT even though the criteria for both are very low. The determinants of soil quality were C-organic, CN ratio, N-total, P-available, calcium, sodium, potassium, base saturation, content weight, moisture content and porosity. The Soil Quality Index of both lands have low criteria but GT has a higher value (0.34) than GTT (0.27). Even though the IKT value in GT is higher, there are many negative impacts caused by burning peatlands. Therefore, the government forbids burning of land by issuing policies to prohibit the burning of forests and peatlands.

AbstractThe assessment of soil quality indices in waste leachate-affected soils is vital to understand the threats of land quality degradation and how to control it. In this respect, a study was conducted on the effects of uncontrolled landfill leachate on soil quality index (SQI) in calcareous agricultural lands using 28 soil variables. Using the total data set (TDS) and minimum data set (MDS) approaches, the SQI was compared between leachate-affected soils (LAS) and control soils by the integrated quality index (IQI) and nemoro quality index (NQI) methods. The results revealed that LAS were significantly enriched by soil salinity-sodicity indices including electrical conductivity (EC), sodium adsorption ratio (SAR), and exchangeable sodium percentage (ESP), fertility indices including total N, available P and K, organic carbon, and cation exchange capacity (CEC), exchangeable cations (Ca, Mg, K, and Na), the available and total fractions of heavy metals (Zn, Cu, Cd, Pb, Ni). After the leachate got its way into the soil, the values of IQI and NQI were dropped ranging 5–16% and 6.5–13% for the TDS approach and 5–15.2% and 7.5–12.2 for the MDS approach, respectively. Clearly, the data showed that soil quality degradation was encouraged and stimulated by the leachate. Among the different models of SQI applied in the present study, IQI determined by MDS was the optimal model to estimate soil quality and predict crop yields given the analysis of the correlations among the SQI models, the correlations between the SQI models and wheat yield, and sensitivity index values.

Dwindling water resources have drawn global attention to the reuse of treated wastewater (TWW) for irrigation. However, the impact of continuous TWW applications on soil quality and the proper quantification and monitoring frameworks have not been well-understood. This study aims to provides an insight into the impact of flood irrigation of urban TWW on soil nutritional-chemical attributes and the potential application of multiple soil quality indices for a corn cropping system. To achieve that goal, we pursued the Total Data Set (TDS) and Minimum Data Set (MDS) approaches, as well as the Integrated Quality Index (IQI) and Nemoro Quality Index (NQI) models. A total of 17 soil nutritional-chemical indicators (0–50 cm depths) were determined for the soils irrigated with TWW (five sites) and well water (one site as control) in West Azerbaijan province in northwestern Iran. Results revealed a significant difference in the majority of soil nutritional-chemical attributes, IQI-TDS, NQI-TDS, IQI-MDS, NQI-MDS, and corn yield between the TWW-irrigated and well-irrigated soils. Irrigation with TWW resulted in a significant increase in the amount of organic matter and cation exchange capacity by 9–17% and 17–26%, respectively, macronutrients (N, P, K, Ca, and Mg) by 22–164%, and the majority of trace metals (Fe, Mn, Zn, and Cu) by 17–175%, suggesting an improvement in soil nutrients and an increase in productivity. Comparing to the soil in control sites, the TWW irrigation caused a notable increase in the values of IQI-TDS, NQI-TDS, IQI-MDS, and NQI-MDS models ranging 14.6–29.5%, 19.1–25.5%, 21.7–33.3%, and 18.4–23.7%, respectively. This implies that soil quality was ameliorated to a significant extent with TWW irrigation. These improvements resulted in a remarkable increase in corn yield ranging from 12.5% to 28.1%. The regression equations revealed that up to 78%, 47%, 72%, and 36% of the variance in the IQI-TDS, NQI-TDS, IQI-MDS, and NQI-MDS models, respectively, could be captured by corn yield. The results of the regression and correlation analyses showed that the IQI-MDS model was more accurate than the other models in assessing soil quality and predicting crop yield. These findings may be an effective and practical tool for policy making, implementation, and management of soil irrigated with TWW.

Soil quality is the ability of soil that plays a role in maintaining plant productivity, preserving and maintaining water availability and supporting human activities. Soil quality assessment is measured based on indicators that describe important soil processes based on the physical, chemical and biological properties of the soil. The level of soil quality in a plot of land is assessed based on the soil quality index. This research was conducted from August to December 2020 in the Supiturung Micro Watershed, Kediri Regency, East Java using a graphical survey method based on the Land Map Unit. Soil samples were taken at a depth of 0-20 cm at each observation point (20 points) for analysis in the laboratory. Soil quality indicators are determined based on key soil properties with the Minimum Data Set (MDS) method, with soil quality indicators from soil physical properties including texture, bulk density, porosity and soil chemical properties including pH, available-P, exchangeable-K, total-N, organic-C. Soil quality index was calculated by weighting soil quality indicators with criteria which divided into 5 classes, i.e. (i) very low class (0.00-0.19), (ii) low (0.20-0.39), (iii) moderate (0.40-0.59), (iv) good (0.60-0.79) and (v) very good (0.80-1.00). The results showed that the soil in land unit 2 had different limiting factor values on the percentage of sand and dust from the soil texture, the total-N content of the soil and the organic-C content of the soil which caused differences in soil quality. There are two indicators of soil quality, namely the percentage of dust from the soil texture and the total N content of the soil which has the most influence on the soil quality index.

<p><strong>Abstrak.</strong> Lahan dalam kawasan tambang-tambang mineral mengalami perubahan sifat fisik, kimia, dan biologi tanah serta lansekap yang sangat signifikan sebagai akibat dari berbagai aktifitas penambangan seperti land clearing, pembangunan fasilitas pendukung kegiatan penambangan, lalu lintas kendaraan berat, penggalian, penimbunan bahan galian, pengolahan hasil tambang atau bahan mineral, dan lainnya. Sangat penting untuk mengembalikan kualitas tanah seperti kondisi sebelum kegiatan penambangan sehingga lahan dapat difungsikan kembali untuk pertanian. Makalah ini membahas metode penilaian indeks kualitas tanah sehingga dapat dievaluasi dampak berbagai perlakuan reklamasi. Sejumlah hasil penelitian menunjukkan bahwa penggunaan indeks kualitas tanah untuk tujuan tersebut memberikan hasil yang baik, mudah dilaksanakan dan mudah dipahami oleh pengguna. Pemilihan indikator kunci (minimun data set) dan nilai ambang batasnya, pada batas mana tanah dapat berfungsi optimal, sangat menentukan akurasi penetapan indeks kualitas tanah. Penskoran dan pembobotan dilakukan terhadap setiap individu indikator kunci yang kemudian diintegrasikan untuk mendapatkan satu nilai indeks kualitas tanah. Indikator kunci untuk mengevaluasi kualitas tanah pada lahan bekas tambang disarankan sebagai berikut: kandungan bahan organik tanah (SOM), reaksi tanah (pH), berat isi tanah (BD), kapasitas air tersedia (AWC), agregasi (WSA), dan respirasi tanah, namun dapat ditambahkan indikator lain sesuai tujuan evaluasi dan kondisi geografis lahan yang akan dievaluasi. Penilaian kualitas tanah dapat juga dilakukan menggunakan metode Scorecard. Evaluasi kualitas tanah pasca penambangan sebaiknya dilakukan sebelum pelaksanaan reklamasi untuk menentukan prioritas sifat-sifat tanah yang perlu perhatian lebih sehingga perlakuan reklamasi lebih terarah dan terukur dan selama pelaksanaan reklamasi untuk mengetahui arah perubahan yang terjadi.</p><p><em><strong>Abstract.</strong> Land in the mining areas undergo changes in soil physical, chemical, and biological properties as well as landscape as a result of various mining activities namely land clearing, construction of facilities to support the operations, movement of vehicles, excavation, storage of overburden dump materials backfilling of excavated material, and mineral mined processing. It is essential to restore soil quality similar to the condition before mining operation so that it can be utilized for agriculture purposes. This paper discusses method for assessing soil quality index to allow evaluation of the impact of different reclamation treatments. Studies indicated that the use of soil quality index gave good result, easy to perform, and easy to understand by the end user. Selection of key indicators (minimum data set) and its threshold values, in which soil is functioning optimally, is essential for the accuracy of soil quality index determination. Scoring and weighing of the individual soil indicator was performed before integrating all key indicators to obtain a soil quality index. Key indicators for evaluating soil quality of reclaimed mine soils is recommended to include soil organic matter (SOM), soil reaction (pH), bulk density (BD), available water capacity (AWC), water stable aggregate (WSA), and soil respiration, however, other indicators could be added depending upon the goal of assessment and geographical condition of land that is subject to evaluation. Qualitative assessment of soil quality can also be conducted using scorecard method. Evaluation of post-mining soil quality should be conducted before any reclamation activities to priorities soil properties that need more attention, so that reclamation treatments will be more focus and measurable and on on-going reclamation to monitor the trend of change.</em></p>
