Tea plantations are mostly more suitable to be cultivated in areas with highland characteristics to get its’ subtropical climate which is great for the growth of tea. This requirement showed that tea plantations are also cultivated in areas with different ranges of slope and this condition could affect soil chemical properties such as soil nutrient content, including soil pH, soil organic carbon (SOC) and contents of N, Available P, K and Mg inside the soil. This study was conducted to analyze the correlation on different slope levels with soil nutrient contents by collecting the secondary data of land slope and soil chemical properties, analyzed statistically with a simple correlation method. The result showed there was no significant correlation between the slope levels and contents of soil chemical properties. Most of the soil chemical properties have a negative correlation to different slope gradients such as soil pH (r = -0.391), SOC (r = -0.348), total N ( r = -0.169), Available P (r = - 0.039), K content (r = -0.135), Mg content (r = -0.027). where the highest levels of nutrients were found at the lowest level of slope based on the site data. Soil chemical properties are needed to be considered in many tea plantations with different levels of slope and could be used as a recommendation in planning for conservation or restoration of degraded land or soil.

The Relationship

Healthy soil could support plant growth by optimizing the availability of nutrients. The availability of nutrients influences the health of tea plants. Nutrient deficiencies would affect the plant physiology that exhibits the plant withering. This study aimed to define the relationship between soil nutrient availability with plant nutrient uptake. This research was conducted by managing secondary data soil chemical properties, and tea plant nutrients analyzed statistically with Pearson correlation. This study only found a significant correlation between soil pH with P and Mg uptake. Correlation results between soil nutrient and plant nutrient uptake obtained a significantly negative correlation on soil pH with P and Mg nutrients with a correlation value of pH-P (r=-0.52), pH-Mg (r=-0.52). There was no correlation between other soil nutrients and plant nutrient uptake. The results of this study can be used to determine the dose of fertilization and the management recommendation of tea plants.

Several rehabilitation treatments have been applied to mitigate runoff and sediment in machine trafficked areas following logging operations, while the knowledge on the consequence of these remediation techniques on the recovery of soil properties remains scarce. The objective of the study was to determine the effect of different rehabilitation treatments including sawdust mulch (SM), water diversion structure (WDS), untreated/bare trail (U), and undisturbed or control area (UND) on the recovery of soil chemical properties over a six-year period after machine-induced compaction occurred on three longitudinal trail gradients (10, 20, and 30 %).In each treatment, the following soil properties were measured: litter thickness, pH, EC, soil organic C, total N, and available P, K, Ca, and Mg. Five sampling plots (with 10 m length and 4 m width) were positioned in each trail gradient classes and three of these plots were randomly considered for soil sampling.The results demonstrate that litter thickness differed among the three treatments, with the highest amount present on the UND area and lowest on the U treatment. Meanwhile, the highest pH (6.75), EC (0.21 Ds m−1), N (0.27 %), available P (14.61 mg kg−1), available K (123.5 mg kg−1), available Ca (135.1 mg kg−1), and available Mg (42.1 mg kg−1) and the lowest C (1.21 %) and C/N ratio (7.83 %) were found on the SM with gradient of 10 % compared to other gradient classes on SM, WDS and, U treatments. The recovery value of litter depth, pH, EC, C, N, C/N ratio, and available nutrients (P, K, Ca, and Mg) were higher on the SM than the WDS at the gradient of 10 %, while significantly higher levels of these variables were measured under WDS installed on trail gradients of 30 % and 20 % when compared with the same gradients on SM. Results of the study revealed that soil chemical properties showed some evidence of recovery following SM and WDS rehabilitation treatments compared to U, although these properties did not fully recover within 6 years as compared to UND area.

Open pit coal mining is common practice to extract coal from lithosphere. This system, however, will bring about soil degradation. Organic fertilization is an alternative to recover fertility of the degraded soil. The objectives of the experiment were to determine nitrate downward movement and change of selected chemical properties in the soil column and to compare the growth of lamtoro (Leucaena leucocephala) as affected by local based liquid organic fertilizer. Column experiment was conducted using mine spoiled soil from Taba Penanjung Sub-District, Central of Bengkulu District, Bengkulu, Indonesia located at approximately 364.5 m above sea level. The experimental design was Completely Randomized Design with 3 treatments consisting of control, 75 and 150 ppm of local based liquid organic fertilizer (LOF). The treatment was replicated 3 times. Soil column was prepared using PVC pipe with diameter of 12.5 cm and length of 40 cm. Soil sample was put into the column and compacted by knocking the base of the column until the soil height achieved 35 cm. Lamtoro was raised in the column for 11 weeks. At the end of experiment, lamtoro shoot was cut and the PVC column was cleaved horizontally and soil was pushed out from the column. Soil sample was, then, sliced into 6 fractions, representing depth of 0-5, 5-10, 10-15, 15-20, 20-25, and > 25 cm. Fresh soil sample from each depth was extracted by distillated water and analyzed for NO3- N. Remaining of soil samples was air-dried for 72 hours, grinded with 0.5 mm screen, and analyzed for available P, exchangeable K, soil pH and exchangeable Al. The experiment indicated that local based liquid fertilizer significantly increased soil NO3-N, available P, exchangeable K, soil pH and reduced exchangeable Al. Higher rates of LOF caused increase in selected soil chemical properties but exchangeable Al. However, NO3-N was potential to move downward to deeper depth of the soil profile. Change of exchangeable Al, soil pH and exchangeable K was observed until 20-25 m depth of soil profile, but change of available P was detected only to 10-15 cm depth. Better soil chemical properties were followed by enhancement of lamtoro growth.

The aim of this research work was to map the status of soil nutrients in the Bisankhel catchment of Chitlang VDC, Makawanpur, Nepal. The study area covered 1023.25 hectares of land, extending from 85°8'8.433"E to 85°10'10.198"E longitude and 27°37'24.251"N to 27°40'21.560"N latitude. Total Nitrogen (N), available Phosphorus(P), extractable Potassium (K), soil organic matter (SOM) and soil pH were measured for 50 soil samples collected using random sampling representing different land uses in the study area. Most of the samples were found very acidic where uplands (4.879±0.119) were more acidic than lowlands (5.036±0.0973). Most samples upon analysis were found to be medium in SOM and total N. SOM was slightly higher in lowlands (3.385±0.256%) than in uplands (3.05±0.206%). Total N was also slightly higher in lowlands (0.145±0.00634%) than in uplands (0.127±0.00639%). Similarly, Available P and K were found very high in majority of the soil samples. Available P was slightly higher in lowlands (92.34±16.96ppm) than in uplands (71.58±15.47ppm). However, extractable K was slightly more in uplands (269±31.32ppm) than in lowlands (240.4±23ppm). Spatial prediction using various interpolation methods was performed in ArcGIS 10.5 software platform using ‘Geostatistical Analyst’ extension. The predicted values in raster data structure were used for mapping the soil fertility status of the catchment. Different interpolation methods were evaluated following cross-validation approach. Comparison of prediction errors was carried out to select the optimum prediction methods for the interpolation of soil nutrient values. Completely Regularized Spline and Ordinary Kriging methods were found to yield better prediction of soil nutrient status among the Deterministic and Kriging methods respectively. Soil pH being the limiting factor, pH control was necessary.

In this study, soil pH, organic matter, total N, total P, total K, alkali-hydrolyzable N, available P, available K, number of microorganism and enzyme activity were studied in a burnedE. urophyllaforest (the burned forest) and an unburned adjacentE. urophyllaforest (the control) in Dongyuan County, Guangdong Province, China. This study aims at investigating the effects of a single wildfire on soil properties of anE. urophyllaforest to provide basis for the recovery of soil fertility and management of burnedE. urophyllaforests. Significant differences were observed between the burned forest and the control in most of chemical properties. The wildfire significantly decreased the soil organic matter, total N, total P, total K, alkali-hydrolyzable N and available K by 32.8%, 33.6%, 36.8%, 35.2%, 25.0% and 28.5%, respectively. However, no significant difference was observed in soil pH and available P. The numbers of bacteria and fungi in burned forest were significant lower than those of the control, while there was no difference in actinomycetes between the two forests. The urease, phosphatase and catalase activities were statistically significant lower than those of the control. The results suggested that there were significant effects on theE. urophyllaforest 1 year after the wildfire and the recovery from the wildfire may take a long time.

Aim: A pot experiment was carried out to determine the effect of sawdust ash and lime (Ca(OH)2) on soil characteristics and yield of sunflower in acidic soil of southeastern Nigeria. Study Design: The experiment was laid out in split-plot design, using sawdust ash (0, 1, 2, 3, 4 t ha-1) as the sub plot and lime (0, 0.5, 1.0, 1.5 t ha-1) as the main plot. Place and Duration of Study: Study was conducted outdoors at Michael Okpara University of Agriculture Umudike, Nigeria, during the 2010 planting season. Materials and Methods: Treatment combinations were applied to the 60 buckets containing soil, mixed thoroughly and watered adequately. After 1 week of treatment application, two sunflower seeds were planted and later thinned to one seedling per bucket. Plant growth and yield data were collected. Pre planting and post-harvest soil samples were collected and analyzed for soil properties. Results: Results showed that with the exception of organic carbon there was significant effect of treatments on all soil chemical properties. Lime and sawdust ash (SDA) as single and combined treatments significantly increased total nitrogen (P=0.05), available phosphorus (P<0.010), and base saturation (P<0.012). The interaction between SDA and lime significantly (P=0.05) increased total exchangeable bases and effective cation exchange capacity, while soil pH was significantly increased (P=0.05) by single applications. The increases in soil chemical properties led to significant positive response of the sunflower. With the exception of number of leaves, other plant parameters (Plant height, stem diameter, head weight, 50 seed weight, head diameter) had significant increases for sawdust ash alone at P=0.05. Correlation studies showed positive significant relationship between soil pH and sunflower yield. Conclusion: The study showed that sunflower performed best at the combination of 3 tha-1 SDA and 1.5 t ha-1 lime producing a mean head weight of 45.4 g.

Understanding the nutrient dynamics in acid soil is fundamental to carry out proper management. The study was conducted to investigate phosphorus (P) pools and selected properties under different rates of lime for acid nitisols of Farawocha, Southern Ethiopia. Four lime rates incubated for a month in three replications were tested. The lime rates were 0 t/ha (0%), 5.25 t/ha (50%), 10.5 t/ha (100%), and 15.75 t/ha (150%). Lime requirement (LR) for 100% was calculated targeting soil pH of 6.5. Data on the P pools such as soluble P (P-sol) and bounded forms of P with iron (Fe-P), aluminum (Al-P), calcium (Ca-P), organic part (Org-P), residual P (Res-P), and total of P fractions were measured. In addition, changes in soil chemical properties such as pH, exchangeable acidity, calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), copper (Cu), boron (B), zinc (Zn), and manganese (Mn) were analyzed. The result showed that total P was 357.5 mg/kg. Compared to nontreated soil, liming at a rate of 15.75 t/ha significantly improved P-sol (34.2%, r2 = 0.88), Ca-P (61.6%, r2 = 0.92), and Res-P (195%, r2 = 0.94); however, it reduced Fe-P (58.5%, r2 = −0.83), Al-P (71%, r2 = −0.97), and Org-P (19.1%, r2 = 0.93). Overall, the P-associated fractions in the soil, regardless of the lime rates, were in the order of Org_P > Res_P > Fe_P > Ca_P > Al_P > P-sol. Liming raised soil pH by 2.1 units (4.5 to 6.6) over nonlimed soil, whereas it reduced exchangeable acidity from 4.18 to 0.23 meq/100 g soil. Available P, Ca, Mg, S, Cu, Zn, and B contents were significantly improved with lime application. However, liming reduced Fe and Mn contents. In conclusion, these findings showed that liming facilitated the release of P from various pools, modified pH and exchangeable acidity, and resulted in beneficial changes for most of the soil chemical properties.

Low soil organic matter, low nutrient availability and the higher soil pH (more than 8) are the major problem of agricultural practices in region of Toshka. An incubation trial at October 2019 was conducted to investigate the effect of potassium humate (KH) and micronic sulfur (MS) on some chemical properties of different soils (sandy clay soils, loamy sand and sandy soils). The used amendments (KH and MS) were added to the studied soil at 4 levels of each amendment i.e. 0.0, 0.25, 0.50 and 1.0%. A two way randomized completely block design and provided with three replications. Studied parameters were included soil pH, EC, exchange Na and the content of available - P and K. Results showed that, the MS application at 1% level caused a significant decrease in soil pH values compared with the KH application and control treatment. These reductions were more pronounced in case of soil B (loamy sand). Also, KH application gave an increase on exchange Na and available-K. While MS application was cause an increased in soil EC and available-P in the three soils under study. Moreover, the increases in the percentage of available – K with added of KH were higher than added of MS for soils under study. While the percentages of available-P with added of KH were higher than with added of MS for studied soils. It may be recommended to add KH and MS at a rate of 1% to improve the soil chemical properties. But the effect of application from MS has greater than KH to increase dissolved sodium salts on the form of sodium sulfate, which facilitates disposal during soil drainage.
