Variability in Soil Macronutrient Stocks across a Chronosequence of Masson Pine Plantations

Plantations play a vital role in the global nutrient cycle because they have large stocks of soil macronutrients. However, the impacts of plantations on soil macronutrient stocks combined with stand age and soil physicochemical properties have not been well quantified. We compared soil macronutrient stocks at soil depths of 0−20 and 20−40 cm across a 7-, 14-, 25-, and 30-year chronosequence of Masson pine (Pinus massoniana Lamb.) plantations. The results showed that the nitrogen (N), phosphorus (P), and potassium (K) stocks first increased and then decreased with stand age. The highest N and P stocks were observed in the 14-year-old plantation, and the 25-year-old plantation displayed the highest K stock. The C, N, and P stocks declined with increasing soil depth across all sites, whereas the reverse trend was found in the K stock. Carbon stocks were highest for all plantations, followed by the K, N, and P stocks. Plantation soils exhibited a higher C:P ratio and a lower P:K ratio at various soil depths. The dominant controlling factors for the soil macronutrient stocks varied significantly at different stand ages and soil depths according to statistical analysis. For the total soil system, the C stock was affected by the available nutrients, organic matter, and stoichiometry; the available nutrients and organic matter were the determinant factors of the N and P stocks. Aggregate stability could be the primary parameter affecting the K stock. Organic matter explained most of the variation in soil macronutrient stocks, followed by the P:K ratio and available K. Collectively, our results suggest that the response of soil macronutrient stocks to stand age and soil depth will be dependent on different soil physicochemical properties, and P and K may be important limiting factors in Masson pine plantation ecosystems.

Effects Of Land Use

The study was conducted to investigate the effects of land use, depth and topography on soil physicochemical properties at the Wadla Delanta Massif, northcentral Ethiopia. Four land uses (natural forest, shrub, grazing and cultivated land), three soil depths (0-20, 20-40, 40-60 cm) and three topographic positions (upper, middle and lower) in three replications were considered for this study. A total of 108 composite samples were collected for laboratory analysis. The results show that particle size distribution was affected by the main effects of land use and soil depth; bulk and particle densities, total porosity, organic matter and total nitrogen contents, C:N ratio and available phosphorus were significantly affected by the interaction of land use by soil depth only, whereas, soil pH, electrical conductivity, exchangeable bases, cation exchange capacity, percent base saturation and extractable micronutrients were affected by the interaction effects of the three factors. Highest clay and bulk density were recorded at the bottom layer of the cultivated land soils, while the utmost porosity, organic matter and nitrogen contents, and available phosphorus were recorded at the surface layers of the natural forest land soils. Highest pH was at the bottom layer of the cultivated land at the three topographic positions. Highest exchangeable bases and cation exchange capacity were observed in the bottom layers of soils under the four land use types at the lower topographic position, whilst extractable micronutrients were recorded at the surface layers of the forest land soils at the upper topographic position. In general, most of the measured soil properties were measured better in forest than in other land use soils and the lower topographic positions than the upper and middle ones. Interaction of land use with topography showed negative effects especially on cultivated and grazing land soils in all topographic positions. Therefore, integrated soil fertility management and soil conservation measures are required in all topographic positions to maintain soil physicochemical properties.

The Relationship

Abstract Background Ferula sinkiangensis is an increasingly endangered medicinal plant. Arbuscular mycorrhiza fungi (AMF) are symbiotic microorganisms that live in the soil wherein they enhance nutrient uptake, stress resistance, and pathogen defense in host plants. While such AMF have the potential to contribute to the cultivation of Ferula sinkiangensis, the composition of AMF communities associated with Ferula sinkiangensis and the relationship between these fungi and other pertinent abiotic factors still remains to be clarified. Results Herein, we collected rhizosphere and surrounding soil samples at a range of depths (0–20, 20–40, and 40–60 cm) and a range of slope positions (bottom, middle, top). These samples were then subjected to analyses of soil physicochemical properties and high-throughput sequencing (Illumina MiSeq). We determined that Glomus and Diversispora species were highly enriched in all samples. We further found that AMF diversity and richness varied significantly as a function of slope position, with this variation primarily being tied to differences in relative Glomus and Diversispora abundance. In contrast, no significant relationship was observed between soil depth and overall AMF composition, although some AMF species were found to be sensitive to soil depth. Many factors significantly affected AMF community composition, including organic matter content, total nitrogen, total potassium, ammonium nitrogen, nitrate nitrogen, available potassium, total dissolvable salt levels, pH, soil water content, and slope position. We further determined that Shannon diversity index values in these communities were positively correlated with total phosphorus, nitrate-nitrogen levels, and pH values (P < 0.05), whereas total phosphorus, total dissolvable salt levels, and pH were positively correlated with Chao1 values (P < 0.05). Conclusion In summary, our data revealed that Glomus and Diversispora are key AMF genera found within Ferula sinkiangensis rhizosphere soil. These fungi are closely associated with specific environmental and soil physicochemical properties, and these soil sample properties also differed significantly as a function of slope position (P < 0.05). Together, our results provide new insights regarding the relationship between AMF species and Ferula sinkiangensis, offering a theoretical basis for further studies of their development.

ABSTRACTBurkholderia pseudomalleiis a soil-dwelling bacterium and the cause of melioidosis, which kills an estimated 89,000 people per year worldwide. Agricultural workers are at high risk of infection due to repeated exposure to the bacterium. Little is known about the soil physicochemical properties associated with the presence or absence of the organism. Here, we evaluated the soil physicochemical properties and presence ofB. pseudomalleiin 6,100 soil samples collected from 61 rice fields in Thailand. The presence ofB. pseudomalleiwas negatively associated with the proportion of clay, proportion of moisture, level of salinity, percentage of organic matter, presence of cadmium, and nutrient levels (phosphorus, potassium, calcium, magnesium, and iron). The presence ofB. pseudomalleiwas not associated with the level of soil acidity (P= 0.54). In a multivariable logistic regression model, the presence ofB. pseudomalleiwas negatively associated with the percentage of organic matter (odds ratio [OR], 0.06; 95% confidence interval [CI], 0.01 to 0.47;P= 0.007), level of salinity (OR, 0.06; 95% CI, 0.01 to 0.74;P= 0.03), and percentage of soil moisture (OR, 0.81; 95% CI, 0.66 to 1.00;P= 0.05). Our study suggests thatB. pseudomalleithrives in rice fields that are nutrient depleted. Some agricultural practices result in a decline in soil nutrients, which may impact the presence and amount ofB. pseudomalleibacteria in affected areas.IMPORTANCEBurkholderia pseudomalleiis an environmental Gram-negative bacillus and the cause of melioidosis. Humans acquire the disease following skin inoculation, inhalation, or ingestion of the bacterium in the environment. The presence ofB. pseudomalleiin soil defines geographic regions where humans and livestock are at risk of melioidosis, yet little is known about the soil properties associated with the presence of the organism. We evaluated the soil properties and presence ofB. pseudomalleiin 61 rice fields in East, Central, and Northeast Thailand. We demonstrated that the organism was more commonly found in soils with lower levels of organic matter and nutrients, including phosphorus, potassium, calcium, magnesium, and iron. We also demonstrated that crop residue burning after harvest, which can reduce soil nutrients, was not uncommon. Some agricultural practices result in a decline in soil nutrients, which may impact the presence and amount ofB. pseudomalleibacteria in affected areas.

Properties Of Soil

An experiment was conducted to examine the physicochemical properties of soil at Habla union under Basail upazila in Tangail based on the BINA (Bangladesh Institute of Nuclear Agriculture) laboratory analysis of physical and chemical parameters during January to March, 2014. Total 30 soil samples from 10 points of Habla union were collected from 0-15 cm, 15-30 cm, and 30-40 cm depth of the soil respectively. To determine the soil texture the results were compared with the standard value of SRDI and BARC. Among the 30 soil samples, 25 soils texture classes were found sandy clay loam, 4 were sandy clay and rest one was clay loam. The comparative analysis showed that the average texture class is sandy clay loam. The bulk density ranged from1.23 to 1.91 g/cm3 for the total samples which leads to decide that bulk density is gradually increasing with soil depth. The moisture percentage at different depth of soil were 39.23 to 57.23 % (for 0-15 cm), 43.02 to 58.35 % (for 15-30 cm) and 42.08 to 58.24% (for 30-45 cm).The pH obtained from soil samples of the study area were 4.66 to 5.55 (for 0-15cm), 5.37 to 6.18(for 15-30cm), 6.33to 6.60 (for 30-45 cm). The percentage of organic matter of the soil samples were 0.55 to 3.97 % (for 0-15cm), 0.55 to 3.24 % (for 15-30cm), 0.69 to 2.28 % (for 30-45cm).The organic matter content in the surface soil is relatively low compared to standard level that decreases steadily with depth. The percentage of nitrogen (N %) was observed in different depth of the soil were 0.078 to 0.126 % (for 0-15 cm), 0.049 to 0.126 % (for 15-30 cm), to 0.074 % (for 30-45 cm) which revealed that the percentages of total nitrogen were fall with the depth compared to standard level. In different depth of soil, it was observed that the level of phosphorus (P) was very low compared to standard level where the phosphorus (P) concentration of the soil samples were 1.18 to 2.90 mg/kg (for 0-15 cm), 1.30 to 9.95 mg/kg (for 15-30 cm), 1.58 to 10.92 mg/kg (for 30-45 cm). On the other hand, it was observed that the sulfur (S) concentration was increased with the depth of soil compared to standard level. The sulfur (S) concentration of the soil samples were 5.21 to 11.98 mg/kg (for 0-15 cm), 5.37 to 14.16 mg/kg (15-30 cm), 9.03 to 15.09 mg/kg (30-45 cm). The potassium (K) concentration of the soil samples were 0.038 to 0.102 mg/kg (for 0-15 cm), 0.031 to 0.90 mg/kg (for 15-30 cm) 0.055 to 0.171 mg/kg (for 30-45 cm), which indicated that the low K content compared to the standard level. The overall physicochemical parameter of soil samples were not optimum for good agricultural production. As we know all the parameters either directly or indirectly influence the soil fertility and productivity. This was probably the reason for low productivity of soil in the study area.Asian J. Med.

No Till

No-till (NT) practice has been widely adopted to improve soil quality, but soil compaction and soil organic carbon (SOC) stratification under long-term NT limit crop production. Strategic tillage (ST), based on single tillage, is proposed as an attractive management practice to sustain the benefits of continuous NT and mitigate its adverse effects. Four tillage systems, including continuous rotary tillage (RT), NT, rotary tillage + subsoiling (RS), and no-till + subsoiling (NS), were implemented to investigate the effects of strategic tillage (i.e., RS and NS) on soil physical properties (compaction and aggregates), SOC, and crop yield in the North China Plain (NCP). The results showed that ST as expected decreased soil bulk density, penetration resistance, and SOC stratification compared with RT and NT at 0–20 cm soil depth (p < 0.05). At 0–10 cm soil depth, more macroaggregates (>0.25 mm) were observed in NT and NS, contributing to higher mean weight and geometric mean diameters, this compared with RT and RS. Additionally, macroaggregate associated SOC was higher, thus resulting in higher SOC storage in NT (31.4–33.4 Mg ha −1) and NS (33.3–35.4 Mg ha−1) at 0–30 cm depth (p < 0.05). Low soil compaction and high SOC in NS were beneficial for the grain yield of wheat and maize, significantly higher by 8.7–32.5% and 14.0–29.8% compared with the other treatments, respectively (p < 0.05). Based on our findings, NS seems to be a promising alternative tillage system to improve soil physicochemical properties and crop production in the NCP. More studies are therefore needed to better understand the benefit of NS.

Masson Pine Forest

With increasing age, plants will cause changes in soil physicochemical properties. The objective of this study was to investigate differences in the soil physicochemical properties in different-aged Masson pine forest plantations (i.e., 10, 20, 40, and 60 years old). Soil samples were collected in a pure Masson pine forest plantation in Southwest China. The soil determination indexes included organic carbon, nitrogen, phosphorus and potassium contents, water content, bulk density, and pH. The soil pH of a 20-year-old forest was significantly (p < 0.05) higher than that of a 10, 40, and 60-year-old forest. In addition, soil-available phosphorus in a 60-year-old forest was significantly (p < 0.05) higher than that in the other three age forest groups. With increasing forest age, available phosphorus increased, while available nitrogen decreased at 20 years old and then increased at 40 years old. There was a significant positive correlation (p < 0.05) between total nitrogen and available potassium; no significant correlation (p> 0.05) between total phosphorus and total potassium, organic carbon, bulk density, and pH; and a significant negative correlation (p < 0.05) between available phosphorus and the water content. The availability and utilization efficiency of soil nutrients in young forests were higher than those in old forests and the intermediate forest age was an important time point that affected the soil properties. To improve the availability of soil nutrients and ensure the sustainable utilization of soil resources, it is necessary to increase the input of nitrogen and especially phosphorus. More attention should be given to the phytochemometric response with respect to the age of plantations.

Different studies have shown that the effect of eucalyptus trees on soil physicochemical properties is variable, which indicates that more investigations that focus on different specific geographical locations and eucalyptus tree species are required. The objectives of this study was to evaluate the status of soil nutrients under four eucalyptus tree species planted in hedgerow system in comparison with that in its adjacent open land. To achieve these objectives, soil samples were taken from a soil depth of 0-20 cm from 15-20 spots by using auger and composited for respective treatments. Each soil samples analyzed at Teppi soil laboratory following standard procedures. Analysis of variance (ANOVA) and treatments separation were made by using Least Significance Difference (LSD) at 95% probability level. The analysis result indicated that there were no significance differences between Eucalyptus tree species and its adjacent open land in the level of soil nutrients (total N, available P, pH, OM, soil moisture and OC) (p<0.05). The only significant difference recorded between Eucalyptus tree species and its adjacent open land in the level of sand percentage whereas non-significant difference was noticed between the treatments on the level of silt and clay percentage in the study. Finally, the results indicate that the eucalyptus tree species established in hedgerow system on clay soil in high rainfall area have no significant impact on soil physicochemical properties under short rotation period of the tree species.

Soil Variables

The information on soil physicochemical properties is vital for the optimum wood biomass production in forest plantation management. The objective of this study was to determine the topsoil physicochemical properties under different Acacia mangium stand ages and their effect on the growth parameters. Five plots were established randomly within each five different stand ages. In all sample plots, the diameter at breast height (DBH) and the total height of standing trees were measured. Soil samples were collected at a depth of 0 to 20 cm at three random points in each plot, then mixed to get a composite before determining physical and chemical properties. DBH mean and the total height of A. mangium increased as stand age increased. The mean annual volume increment maximised at the 8.5 years old stand with 27.9 m3 ha-1 yr-1. Survival rate and stem density decreased as stand age increased. Principal component analysis (PCA) results showed that the most important soil physical properties were soil organic matter, silt and sand contents, bulk density, and moisture content. For soil chemical parameters, exchangeable magnesium (Mg), cation exchange capacity (CEC), total carbon (TC), total nitrogen (TN), and carbon-to-nitrogen (C/N) ratio were the influential soil variables. Soil pH, available phosphorus (P), and clay content were negatively correlated with the growth development of A. mangium trees. Observations suggest that multiple soil variables are essential for the success of the A. mangium plantation.
