Peran Vegetasi Dominan Pada Karakteristik Tanah di Lahan Bera, Kampung Womnowi, Distrik Sidey, Manokwari

Abstrak: Selama proses suksesi, vegetasi merupakan satu dari komponen utama untuk meningkatkan kesuburan tanah. Tujuan penelitian ini adalah untuk menganalisis dan mendeskripsikan peran vegetasi dominan pada karakteristik tanah di lahan bera berumur 15 tahun Kampung Womnowi, Distrik Sidey, Manokwari. Vegetasi dominan ditentukan berdasarkan data indeks nilai penting (INP) analisis vegetasi. Sampel tanah diambil secara komposit pada luasan lahan 1 hektar dari dua kedalaman tanah (0–10 cm dan 10–20 cm). Vegetasi yang mendominasi lahan bera secara berurutan adalah Pometia pinnata, Dracontomelon dao, Octomeles sumatrana, Lansium domesticum, dan Pimelodendron amboinicum. Kehadiran O. sumatrana mengindikasikan lahan bera tanah aluvial, lebih lanjut terbukti karena lahan bera tersebut berdekatan dengan Sungai Womnowi. Karakteristik fisik tanah didominasi oleh fraksi lempung dan unsur makro lebih tinggi pada kedalaman 0–10 cm dibanding kedalaman 10–20 cm. Karakteristik tanah menunjukkan bahwa tanah tergolong masam (pH 5.4–5.6), kadar karbon organik tanah sedang (1.07–3.39%), kadar nitrogen total rendah (0.17–0.53%), kadar fosfor tersedia tergolong tinggi (10.7–22.4 ppm), kapasitas tukar kation (KTK) tergolong tinggi (10.50–20.32 cmol kg-1), kejenuhan basa tergolong sangat tinggi (65.4–66.7%), dan kadar Al3+ and H+ sangat rendah. Secara keseluruhan urutan KTK menunjukkan Ca > Mg > Na > K yang mengonfirmasi tanah aluvial dan pencucian kalium terjadi dengan cepat. Rendahnya kadar kalium dapat dihubungkan dengan penggunaan unsur tersebut untuk pembentukan buah L. domesticum. Selama pemberaan 15 tahun, vegetasi dominan memengaruhi karakteristik tanah.Kata kunci: vegetasi pohon, kesuburan tanah, analisis tanah, aluvial, Papua BaratAbstract: During succesional season vegetation is one of major compound to increase soil fertility. The purpose of this study was to analyzed and description dominant vegetation and their contribution to soil characteristic at fallow land 15 years old Womnowi Village, Sidey District, Manokwari. To determine dominant vegetations we used data important value index (IVI) of vegetation. Two depth of sample soils (0–10 cm dan 10–20 cm) were taken from one hectare area by composite technique. The dominant vegetation on fallow land dominated by Pometia pinnata, Dracontomelon dao, Octomeles sumatrana, Lansium domesticum, and Pimelodendron amboinicum respectively. Presence of O. sumatrana was indicated that the type of aluvial fallow land, further it is proven because the fallow land is close to the Womnowi River. Soil physical characteristic dominated by clay fractions, macronutrient was higher in depth 0-10 cm than 10-20 cm. Characteristic of soil shows acidic soils (pH 5.4–5.6), moderate of soil organic carbon (1.07–3.39%), total of nitrogen was low (0.17–0.53%), high available phosphorus (10.7–22.4 ppm), moderate cation exchange capacity (CEC) (10.50–20.32 cmol kg-1), very high base saturation (65.4–66.7%), and very lows of Al3+ and H+. Overall the order of CEC shows Ca > Mg > Na > K respectively confirmed aluvial soil and fast leached potassium in soil. Low potassium levels are thought be related to the use of the element for fruits formation of L. domesticum. During 15 year fallowed, dominant vegetation had influence to soil characteristic.Key words: tree vegetation, soil fertility, soil analysis, alluvial, West Papua

During the regular control of soil fertility in the Rasina District, it was established that the plots of land were distributed across Vertisol, Eutric Cambisol and Fluvisol types of soils, and to a lesser extent on Pseudogley and Ranker. The tested samples had different textures - sandy loam and loam, clay-sandy loam and clay loam, and clay. Plots of land that were of very acidic and acidic reactions were predominant, with medium amounts of humus, very low amounts of available phosphorus, and high amounts of available potassium. High or very high cation absorption capacity was found in about half of the examined fields; a deficient content of exchangeable Ca was recorded in 22% of plots and that of exchangeable Mg in 16% of plots, while an unfavorable Ca/Mg ratio was measured in 44% of plots. The overall sensitivity to acidification was mainly moderate (50.6% of plots) and strong (20.2% of plots). Very high concentrations of mobile Al, which could be toxic to plants, were found in 5 field plots.

One of the largest strawberry-producing municipalities of Rio Grande do Sul (RS) is Turuçu, in the South of the State. The strawberry production system adopted by farmers is similar to that used in other regions in Brazil and in the world. The main difference is related to the soil management, which can change the soil chemical properties during the strawberry cycle. This study had the objective of assessing the spatial and temporal distribution of soil fertility parameters using principal component analysis (PCA). Soil sampling was based on topography, dividing the field in three thirds: upper, middle and lower. From each of these thirds, five soil samples were randomly collected in the 0-0.20 m layer, to form a composite sample for each third. Four samples were taken during the strawberry cycle and the following properties were determined: soil organic matter (OM), soil total nitrogen (N), available phosphorus (P) and potassium (K), exchangeable calcium (Ca) and magnesium (Mg), soil pH (pH), cation exchange capacity (CEC) at pH 7.0, soil base (V%) and soil aluminum saturation(m%). No spatial variation was observed for any of the studied soil fertility parameters in the strawberry fields and temporal variation was only detected for available K. Phosphorus and K contents were always high or very high from the beginning of the strawberry cycle, while pH values ranged from very low to very high. Principal component analysis allowed the clustering of all strawberry fields based on variables related to soil acidity and organic matter content.

Essential Information

Abstract Surveys of soil fertility and quality provide essential information, at multiple scales, for policy and management decisions on agricultural and environmental questions. Such surveys are expensive, and national-scale agricultural or geochemical surveys are conducted infrequently by public sector organisations. Where resources are scarce, the costs of management, sample collection, analysis, and data management can be prohibitive. This is likely to create a particular barrier to understanding how soil fertility may influence crop production in contexts where small-scale production is prevalent. Private sector soil laboratories conduct soil fertility analyses on thousands of samples annually: samples are often collected in a systematic way by experienced technical staff. The simple step of collecting location coordinates can greatly extend the utility of the data, beyond the immediate value to the farmer and without an added burden on them. Here we use a dataset of soil organic matter (SOM), plant-available phosphorus (P) and exchangeable potassium (K), from c. 27,000 georeferenced sample points collected in 2014-2017 in Pakistan by Fauji Fertilizer Company (FFC). Geostatistical methods are used to model the spatial variation of these soil properties and predict their values at unsampled locations. The geostatistical model allows the probability that soil properties fall below recommended thresholds for wheat production, and these probabilities are displayed as maps using "calibrated phrases" for probability ranges in the legend. The resulting maps provide a comprehensive overview of key agronomic data across ~194,000 km2 of cropland, realised as a direct consequence of sample location data collection being implemented by FFC. There is spatial structure in the SOM and K data, but not in the P data. These maps can be used to educate agronomists and farmers about typical soil fertility conditions in their region, and where soil analysis is a priority. They can also support more strategic planning of fertiliser needs in Pakistan where widespread nutrient deficiencies are found. This research demonstrates the potential for this approach to be used in many wider geographic contexts where there are few data from one-off survey activities. Additional benefits address concerns about data privacy have thus far limited their integration into a spatially disaggregated output that could benefit wider society.

In arid regions, decreased soil fertility has adversely affected agricultural sustainability. The effects of different amendments in alleviating these issues and increasing soil fertility remain unclear. Herein, a two-year field experiment was conducted to evaluate the properties of grey desert soil and soil respiration (SR) dynamics under six different treatment groups: biochar (BC), leonardite (LD), anionic polyacrylamide (PAM−), cationic polyacrylamide (PAM+) powder, anionic polyacrylamide solution in water (PAM−W), and control (CK). We observed that the BC and LD amendments significantly altered soil pH, organic matter, available nitrogen, available phosphorus, cation exchange capacity, and SR. PAM amendment increased the SR as compared to the control, except in autumn, but PAM did not affect the soil properties. SR under different amendments showed strong seasonal patterns, the highest and lowest SR rates were observed in June and January, respectively. Amendments and seasonal dynamics significantly affected SR, but no interaction was observed between these factors. Temporal variation of SR was substantially influenced by soil temperature at 15 cm of soil depth. Temperature sensitivity of SR (Q10) increased with soil depth and decreased with amendment addition. SR was significantly affected by soil temperature, moisture, air temperature, and their interactions. The outcomes of this study suggested that the BC and LD amendments improved soil fertility and negated the net carbon accumulation by increasing the SR and Q10 in arid agriculture soil.

The successful use of energy-dispersive X-ray fluorescence (ED-XRF) sensors for soil analysis requires the selection of an optimal procedure of data acquisition and a simple modelling approach. This work aimed at assessing the performance of a portable XRF (XRF) sensor set up with two different X-ray tube configurations (combinations of voltage and current) to predict nine key soil fertility attributes: (clay, organic matter (OM), cation exchange capacity (CEC), pH, base saturation (V), and extractable nutrients (P, K, Ca, and Mg). An XRF, operated at a voltage of 15 kV (and current of 23 μA) and 35 kV (and current of 7 μA), was used for analyzing 102 soil samples collected from two agricultural fields in Brazil. Two different XRF data analysis scenarios were used to build the predictive models: (i) 10 emission lines of 15 keV spectra (EL-15), and (ii) 12 emission lines of 35 keV spectra (EL-35). Multiple linear regressions (MLR) were used for model calibration, and the models’ prediction performance was evaluated using different figures of merit. The results show that although X-ray tube configuration affected the intensity of the emission lines of the different elements detected, it did not influence the prediction accuracy of the studied key fertility attributes, suggesting that both X-ray tube configurations tested can be used for future analyses. Satisfactory predictions with residual prediction deviation (RPD) ≥ 1.54 and coefficient of determination (R2) ≥ 0.61 were obtained for eight out of the ten studied soil fertility attributes (clay, OM, CEC, V, and extractable K, Ca, and Mg). In addition, simple MLR models with a limited number of emission lines was effective for practical soil analysis of the key soil fertility attributes (except pH and extractable P) using XRF. The simple and transparent methodology suggested also enables future researches that seek to optimize the XRF scanning time in order to speed up the XRF analysis in soil samples.

Soil acidity is a major factor limiting green beans (Phaseolus vulgaris L.) production in the Cameroon western Highland. A field experiment (split-plot layout) was conducted with seven dolomite treatments (tons ha-1): control or T0 (0), T1 (0.5), T2 (1), T3 (1.5), T4 (2), T5 (2.5) and T6 (3). Soil physico-chemical properties were determined meanwhile growth and yield parameters were collected weekly for a month and analyzed statistically. Results revealed that control soils were texturally silty sandy. The exchangeable bases (except Na), cation exchange capacity (CEC), base saturation and available phosphorus were very high. They acidity was moderate to high (5.2 to 5.6) while organic matter was very high (% dry mass) and of moderate to good quality (11<C/N ratio<13). Crop variety showed a highly significant difference (P<0.001) for all growth and yield parameters, with Cogito producing the longest (13.88 cm), most numerous (40.94 pods per plant) and highest (16.96 tons ha-1) extrafine pods. Dolomite doses revealed no significant effects (P>0.05) on crop parameters, although highest yield (13.61 tons ha-1) of extrafine pods came from 2 tons ha-1. The dolomite dose versus variety interaction showed no significant difference (P>0.05). Farmers ought to improve soils with compost and cover crops to check nutrient leaching and erosion.

Results showed significant (P<0.05) improvement in all soil chemical properties and growth parameters of plant compared to control which had no treatment. However, the effects varied with treatment levels and interactions. While the effects increased with rate of application, interactions consistently showed superior effect on all parameters studied. Thus, combining rice husk dust (RHD) and NPK may increase the soil fertility and growth of Jatropha. Treatments combination of5tonha-1 RHD and 3tonha-1 NPK and 5tonha-1 RHD and 5tonha-1 NPK relatively gave the most appreciable result in soil chemical properties and growth of Jatropha respectively, thus are recommended.

Soil fertility evaluation has been considered as a most effective tool for sustainable planning of a particular region. This study was conducted to determine the soil fertility status of the Agricultural Research Station, Pakhribas, Dhankuta, Nepal. The total 60 soil samples were collected randomly at a depth of 0-20 cm by using the soil sampling auger. For identification of soil sampling points A GPS device was used. The collected samples were analyzed for their texture, pH, OM, N, P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu and Mn status following standard methods in the laboratory of Soil Science Division, Khumaltar. The Arc-GIS 10.1 software was used for soil fertility maps preparation. The observed data revealed that soil was dark yellowish brown (10YR 4/4) and yellowish brown (10YR 5/6) in colour, and single grained, granular and sub-angular blocky in structure. The sand, silt and clay content were 56.61±0.97%, 27.62±0.56% and 15.77±0.58%, respectively and categorized as loam, sandy loam and sandy clay loam in texture. The soil was very acidic in pH (4.66±0.07) and very low in available sulphur (0.53±0.11mg/kg), available boron (0.24±0.07mg/kg). The organic matter (1.34±0.07%), total nitrogen (0.09±0.003mg/kg), available calcium (605.70±31.40mg/kg), available magnesium (55.96±4.67mg/kg) and available zinc (0.54±0.22mg/kg) were low in status. Similarly, available potassium (115.98±9.19 mg/kg) and available copper (1.13±0.09 mg/kg) were medium in status. Furthermore, available manganese (36.31±2.82mg/kg) was high, whereas available phosphorus (105.07±9.89 mg/kg) and available iron (55.80±8.89 mg/kg) were very high in status. The soil fertility management practice should be adopted based on the determined status in the field for the sustainable production of crops. The future research strategy should be built based on the soil fertility status of the research farm.
