<p><strong>Abstract</strong></p><p>Mining is an important industrial sector in Bangka Island (Indonesia) where about 70% of this area is tin mining. The separation of tin via flotation of tin-containing soils results in acidic nutrient-poor soils with very low organic matter contents. Hence, ex-tin mined areas are highly and unsuitable for plant growth due to their un-fertility. To improve soil fertility soil amendments are of vital importance. This research aims to evaluate the impact of different soil amendments on agricultural production and basic soil parameters on the ex-tin mined area.</p><p>The study was conducted on ex-tin mined area located in Bangka Regency, Indonesia (1<sup>o</sup>47’22.9085 S and 106<sup>o</sup>5’47.0461 E). Bangka Regency has a tropical climate with an average daily temperature of 27.2<sup>o</sup>C, precipitation during the growing season is 191.5 mm per month. The field trial was set up in July 2018 by a randomized complete block design with five different soil amendments and control plots for comparison, with a size of 2 x 2 m in four replicates. The treatments consist of the: (1) Control, (2) Lime, (3) Compost; (4) Charcoal and combinations of (5) Charcoal and Compost, and (6) Charcoal and sawdust. The soil was amended with t.ha<sup>-1</sup> for the single amendments (treatments 2-4), and with rate 20 t.ha<sup>-1</sup> for combined amendments (treatments 5 and 6). The plots are used to grow cassava (Manihot esculenta) for 12 months as the main crop and Centrocema pubescens as used as a cover crop grown twice for 6 months to avoid soil erosion. Soil samples were taken before and after harvest to analyze soil properties. Soil samples were analyzed for the following parameters: pH, Dissolved Organic Carbon (DOC), and Electric Conductivity (EC). Crop yields were determined by weighing the total harvest of each crop per plot. The cover crop was harvested in December 2018, and replanted, until the main crop Cassava was harvested (30 July 2019), where the cover crop yield was also evaluated. Cassava yields were separated into belowground and aboveground yields.</p><p>Soil amendments showed positive effects on soil pH, DOC, and EC at harvest time. Lime treatment significantly improved soil pH and EC (7.40 and 72.30 µS.cm<sup>-1</sup> respectively), while DOC was significantly increased by compost treatment. Centrocema pubescens yields were significantly higher at the first harvest compared to the second one. The combined treatment with charcoal (10 t.ha<sup>-1</sup>) + Compost (t.ha<sup>-1</sup>) showed significantly the highest yield for both samplings. While another combined treatment, where, charcoal and sawdust was applied at 10 t.ha<sup>-1</sup> each, showed the highest total cassava belowground biomass (5.44 ton.ha<sup>-1</sup> ) as well as cassava aboveground biomass (3.06 ton.ha<sup>-1</sup>).</p><p>Results of the present field experiment suggest that the application of soil amendments directly affected soil parameters. The effect on yields was positive but crop dependent, likely due to different nutrient requirements. Data on heavy metal uptake by plants regarding soil amendments will be presented. Soil amendments can provide the potential to improve food safety and security in the ex-tin mined area.</p><p>Keywords: ex-tin mined, soil fertility, soil amendments, soil parameters, crop yields</p>

Unscientific land use and cropping techniques have led high soil erosion and degradation of soil quality in the mid-hills of Nepal. To understand the effects of land use systems for selected soil chemical properties in mid-hills, composite soil samples at 0 cm to 20 cm depth were collected from five different land-use systems: Grassland, forest land, upland, lowland, and vegetable farms from Dhading district of Nepal in 2017. Soil samples were analyzed for soil fertility parameters: Soil pH, organic matter (OM), total nitrogen (N), available phosphorus (P), available potassium (K) and its effect due to different land use systems were compared. Results showed that soil pH was neutral in vegetable farms (6.61), whereas the rest of the land-use systems had acidic soils. Soil OM (3.55%) and N (0.18%) content was significantly higher in forest, but the lowest soil OM (1.26%) and N (0.06%) contents were recorded from upland and lowland farms, respectively. Available P was the highest in the vegetable farm (41.07 mg kg−1) and was the lowest in grazing land (2.89 mg kg−1). The upland farm had significantly higher P levels (39.89 mg kg−1) than the lowland farm (9.02 mg kg−1). Available K was the highest in the vegetable farm (130.2 mg kg−1) and lowest in grazing land (36.8 mg kg−1). These results indicated that the land under traditional mixed cereal-based farming had poor soil health compared with adjacent vegetable, grazing, and forest lands among the study area. The variations in soil fertility parameters suggest the immediate need for improvement in soil health of traditional farmlands.

Spatial Spreading

Understanding the spatial spreading patterns of plant-available sulphur (S) (AS) and plant-available micronutrients (available zinc (AZn), available iron (AFe), available copper (ACu), available manganese (AMn) and available boron (AB)) in soils, especially in coastal agricultural soils subjected to various natural and anthropogenic activities, is vital for sustainable crop production by adopting site-specific nutrient management (SSNM) strategies. We studied the spatial distribution patterns of AS, AZn, AFe, ACu, AMn, and AB in cultivated soils of coastal districts of India using geostatistical approaches. Altogether 39,097 soil samples from surface (0 to 15 cm depth) layers were gathered from farm lands of 68 coastal districts. The analysis of soil samples was carried out for soil pH, electrical conductivity (EC), soil organic carbon (SOC) and AS, AZn, AFe, ACu, AMn, and AB. Soil pH, EC and SOC varied from 3.70 to 9.90, 0.01 to 7.45 dS m-1 and 0.02 to 3.74%, respectively. The concentrations of AS, AZn, AFe, ACu, AMn, and AB varied widely in the study area with their corresponding mean values were 37.4±29.4, 1.50±1.53, 27.9±35.1, 2.14±1.74, 16.9±18.4 and 1.34±1.52 mg kg-1, respectively. The coefficient of variation values of analyzed soil parameters varied from 14.6 to 126%. The concentrations of AS, AZn, AFe, ACu, AMn, and AB were negatively and significantly correlated with soil pH and positively and significantly correlated with SOC. The geostatistical analysis indicated stable, Gaussian and exponential best-fit semivariogram models with moderate to strong spatial dependence for available nutrients. The generated spatial spreading maps revealed different distribution patterns for AS, AZn, AFe, ACu, AMn, and AB. There were variations in spatial spreading patterns of AS, AZn, AFe, ACu, AMn, and AB in east- and west-coastal area. About 62, 35, 12, 0.4, 23 and 45% of the study area had deficiency of AS, AZn, AFe, ACu, AMn, and AB, respectively. The spatial spreading maps will be highly useful for SSNM in the cultivated coastal soils of the country. This study could also be used as a base for assessing spatial spreading patterns of soil parameters in cultivated coastal areas of other parts of the world.

Soil is spatially heterogeneous and needs site-specific management. However, soil nutrient information at larger scale in most cases is lacking. Consequently, fertilizer advisory services become dependent upon blanket recommendation approach. Subsequently, it affects yield and profitability. This study is aimed at explaining soil fertility heterogeneity in Wolaita zone, Southern Ethiopia. About 789 soil samples were collected to evaluate soil physical (color, particle size, and bulk density) and chemical properties (pH, OC, N, P, K, Ca, Mg, B, Cu, Fe, Mn, Zn, PBS, and CEC). The laser diffraction method for soil particles and mid-infrared diffused reflectance (MIR) spectral analysis for OC, TN, and CEC determination were employed. Mehlich-III extraction and inductively coupled plasma (ICP) spectrometer measurement were used for the remaining elements. The result based on principal component analysis showed that 52% of the total variations were explained by exchangeable bases, CEC, pH, available P, Cu, B, and particle sizes. Clay texture and acidic soil reaction are dominant. Soil parameters with the following ranges were found at low status: soil OC (0.2–6.9%), total N (0.01–0.7%), available P (0.1–238 mg/kg), S (4–30 mg/kg), B (0.01–6.9 mg/kg), and Cu (0.01–5.0 mg/kg). Besides, low levels of exchangeable Ca, Mg, and K (Mg-induced K deficiency) on 22, 34, and 54% soil samples, respectively, were recorded. The soil contained sufficient Fe, Zn, and Mn. In conclusion, the study aids in developing practical decision for optimum soil management interventions and overcomes lower productivity occurring due to fertilizer use that is not tailored to the local conditions. Overall, continuous cropping, low return of crop residues, and low and/or no fertilizer application might have caused the low status of N, P, K, S, B, and Cu. Therefore, application of inorganic fertilizers specific to the site, lime in acidic soils, and organic fertilizers are recommended to restore the soil fertility and improve crop productivity.

Agroforestry Practices

Soils are the universal reservoirs through which living organisms get the resources for their livelihoods either directly like plants and indirectly like other organisms and animals. The ability of soils to serve as a universal reservoir depends on its fertility. Agroforestry practices have been seen to improve and conserve soil fertility. This research work carried out from the 10th of May 2015 to the 10th of November 2015 was aimed at assessing the role of agroforestry practices in the improvement of soil fertility in the study area. Information was collected using questionnaires, field surveys and the analysis of soil samples in the laboratory. The results obtained were subjected to regression and correlation analysis using the Statistical Package for Social Sciences (SPSS). These results showed that the main agroforestry practices in this area include live fences and scattered trees on farmlands. It was also observed that farmers use indicators such as yields, softening of soil, wilting of the crops, rotten tubers, erosion and rains to determine soil fertility. There was no significant difference between various soil parameters (pH, acidity, CEC, ECEC, C/N, and exchangeable Al) in the two major agroforestry practices identified. There was equally no significant difference between the various soil elements and yields in the two major systems identified. The only element that showed a significant difference (P<5%) in the two systems and also for yields was phosphorous. Since only phosphorous significantly influenced yields in this area, a model was established to show that crop yields are dependent on phosphorous as indicated by the equation Yields = 1.77+ 0.03 P. Scattered trees on farm lands were recommended to farmers, the practice of improved fallow using a local fertilizing species identified as well as the use of Guatemala grass (Tripsacum laxum) and Vetiver grass (Vetiveria zizanoides) should be introduced on slopes to control erosion.

Agronomists consider the continuity and nutrient capturing properties of cover crops as important determinants of nutrient cycling in agricultural systems. Managing for these biotic control functions can help limit nutrient loss and groundwater contamination between main crop harvests. This simulation study highlights the potential role of cover crop management in a welfare economics framework. The objective is to find the optimal combination of nutrient input to the main crop, the extent of off-season cover crops, and crop functional diversity to maximize the sum of benefits from agricultural production and groundwater protection.

AbstractLiming agricultural fields is necessary for counteracting soil acidity and is one of the oldest operations in soil fertility management. However, the best management practice for liming in Germany only insufficiently considers within-field soil variability. Thus, a site-specific variable rate liming strategy was developed and tested on nine agricultural fields in a quaternary landscape of north-east Germany. It is based on the use of a proximal soil sensing module using potentiometric, geoelectric and optical sensors that have been found to be proxies for soil pH, texture and soil organic matter (SOM), which are the most relevant lime requirement (LR) affecting soil parameters. These were compared to laboratory LR analysis of reference soil samples using the soil’s base neutralizing capacity (BNC). Sensor data fusion utilizing stepwise multi-variate linear regression (MLR) analysis was used to predict BNC-based LR (LRBNC) for each field. The MLR models achieved high adjusted R2 values between 0.70 and 0.91 and low RMSE values from 65 to 204 kg CaCO3 ha−1. In comparison to univariate modeling, MLR models improved prediction by 3 to 27% with 9% improvement on average. The relative importance of covariates in the field-specific prediction models were quantified by computing standardized regression coefficients (SRC). The importance of covariates varied between fields, which emphasizes the necessity of a field-specific calibration of proximal sensor data. However, soil pH was the most important parameter for LR determination of the soils studied. Geostatistical semivariance analysis revealed differences between fields in the spatial variability of LRBNC. The sill-to-range ratio (SRR) was used to quantify and compare spatial LRBNC variability of the nine test fields. Finally, high resolution LR maps were generated. The BNC-based LR method also produces negative LR values for soil samples with pH values above which lime is required. Hence, the LR maps additionally provide an estimate on the quantity of chemically acidifying fertilizers that can be applied to obtain an optimal soil pH value.

The aim of the study was to assess of plant available molybdenum (Mo) resources in the solutions of soils as well as to evaluate the effects of selected soil properties on changes of the Mo concentration in the soil solution. Sixty-two soil samples were investigated. The soil solutions were obtained by modified vacuum displacement method. The results showed that Mo concentrations in the soil solutions were much differentiated, ranging from 0.002 to approximately 0.100 µmol/L. Positive correlations were found between soil solution Mo concentration and soil pH as well as the contents of available phosphorous and organic carbon in soil. At the same time, Mo concentration was higher in the soil solutions obtained from soils with larger amounts of soil particles with diameter lesser than<br /> 0.02 mm. Among the analysed soil parameters in this study, soil pH is the most important factor that influences the Mo concentration in soil solution. Studies have shown that in acid sandy soils the amount of molybdenum found in the soil solution is too small to cover the nutritional requirements of the plants. This indicates the need of fertilization with this element. Regular liming of soils and fertilization with phosphorus can improve the availability of molybdenum to plants.
