AbstractMango orchards in Pakistan are deficient in soil micronutrients. Multan is one of the prime regions for mango production in Pakistan; therefore, this study was conducted to evaluate the micronutrient status of mango orchards in the Multan region. Soil samples from four different depths (0–30, 30–60, 60–90, and 90–120 cm) and leaf samples were collected from thirteen different locations of Multan. Depth-wise variations in the micronutrient status and the levels of pH, EC, CEC, SOM, and CaCO3 were determined. All data collected from the field and laboratory work of mango orchards under study were analyzed statistically by applying the RCBD design. It was observed that pH and ECe of soil under study were significantly higher in upper depths when compared with lower depths whereas CaCO3 content was contrary to pH and EC as it was observed to be higher from the lower depth of the soil. Moreover, mango leaves from the majority of locations were deficient in total micronutrients due to poorly available micronutrients status of the soil. Thus, there is a serious need to improve the chemical properties of the soil, and the proper dose of micronutrients should be applied every season for sufficient supply throughout the growing cycle of mango in and around the Multan region.

ABSTRACT: This paper deals with a specific type of homogeneous beechwood called Fageta paupera. The aim is to acquire information about the heterogeneity of soil environment. As a material we used 20 research plots of semi-natural European beech stands, where the sampling of soil profile and the observation of floristic conditions were realized. Laboratory assessment of soil samples was focused on physicochemical and chemical properties of soil: pH/CaCl<sub>2</sub>, K<sup>+</sup>, Ca<sup>2+</sup>, Mg<sup>2+</sup>, CEC (T, S, V), C<sub>ox</sub>, N<sub>t</sub>, C/N, C-FA, C-HA, C-CHL, C-HA/FA. Data processing was done with the aim to discover a variability of soils, observing soil genetic horizons individually (H, A, B, C). Research plots were divided into biotopes with the cover of understory vegetation &lt; 15% and &gt; 15% (in accordance with the definition of Fageta paupera) and the variability of soil properties in each horizon for the two above-mentioned biotopes and furthermore for all plots together was investigated. Results show the highest variability of soil properties in the biotope of Fageta paupera, especially in its holorganic (H) and organomineral (A) horizons. Furthermore, regression analysis showed the strongest dependence of the variability of soil properties in the biotope of Fageta paupera.

Soil physico-chemical properties are an important phenomenon for sustainable crop production and maintenance of optimum soil health. Hence, a laboratory measurement was conducted with soil samples of three years long experimental field of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh to assess the changes in five selected soil physico-chemical properties viz. soil texture, bulk density, soil pH, total nitrogen and organic matter. The experiment was laid out in a split plot design with two water regimes (continuous flooding and alternate wetting & drying) in the main plots and five fertilizer treatments (N0 - control, N1- 140 kg N/ha as PU, N2- 104 kg N/ha as USG (2× 1.8 g/ 4 hills), N3 - 5 t CD + PU @ 140 kg N /ha on IPNS basis and N4- 5 t CD + USG (2× 1.8 g/ 4 hills @ 104 kg N/ha)) in the subplots under rice-rice cropping pattern with three replications. After three years, soil samples were collected at 0-5 and 5-10 cm soil depths for measuring bulk density and at 0-10 cm depth for other soil properties and analyzed. Results found that % sand, % silt, % clay, bulk density and soil pH was not changed significantly compared to initial status. Percentage of total nitrogen and organic matter was significantly affected by irrigation and fertilization. Total nitrogen (%) was higher in AWD whereas organic matter (%) was higher in CF practice. The highest total nitrogen (%) and organic matter (%) was found in N4 treatment in which USG was applied in combination with cowdung as organic manure. It can be suggested that N4 treatment was formed good combination for sustaining chemical properties of soil. Further long- term experimentation will be needed to know the changes in soil properties for sustainable crop production and improving soil health. Asian Australas. J. Biosci.

The risk associated with the presence of heavy metals in soil is their potential toxicity and ability to enter the ecosystem through the food chain. Total heavy metal content of a soil is inadequate for predicting the toxicity of heavy metals in soil. Therefore, the current study was designed to determine the various forms in which the selected heavy metals: Chromium (Cr), Lead (Pb), Nickel (Ni), and Cadmium (Cd) exist in the soil to ascertain the available forms for plant uptake. Soils samples were randomly collected from selected organic and conventional farms in Akinyele local government, Ibadan, Oyo State, Nigeria, at different depths (0-15, 15-30 and 30-45 cm) using random sampling method. Routine analysis was carried out to determine the textural classes and chemical properties of soil samples. The total heavy metals of the soil samples were determined and their fractions were analysed using sequential extraction method. Cadmium was not detected in most of the soil samples. Residual fraction was predominant in all the analysed heavy metals. In addition, Cr was more associated with the oxidizable fraction having a range of 0.1 mg/kg from Ajibode organic farm (AO) at 30-45 cm depth. Pb and Ni were both more associated with reducible fraction with Pb having a range of 2.7 mg/kg in Ajibode conventional farm (AI) at 0-15 cm depth and 0.1 mg/kg in (AI) at 30-45 cm depth. Reducible values of Ni ranges from 4.3 mg/kg in AI at 0-15 cm to 1.4 mg/kg in AO at 30-45 cm. The apparent mobility and bioavailability for these heavy metals in the studied soils were in the order: Pb>Cr>Ni. The result showed that uptake of heavy metals by the plants would be low as the concentration of the exchangeable form of the heavy metals in the analysed soil sample has the least concentration when compared with the other forms.

Chemical Properties Of Soils

Background: Trees often affect the chemical properties of soil, positively or negatively. Objective: This paper studied the effects of Podocarpus falcatus and Markhamia lutea trees on soil chemistry in Ruhande Arboretum, Rwanda. Methods: Soil samples were collected using Zigzag method from Arboretum forest of Ruhande at different depths (0-20, 20-40 and 40-60 cm). For each plot, 25 samples were collected to make one composite sample per plot for each depth. Results: The results showed that tree species contributed to the changes of soil chemistry along the depths of the soil layers. The laboratory analyses showed that there was a high significant influence of tree species on soil pH and Aluminum ions. However, it was observed that there was no significant influence of Podocarpus falcatus and Markhamia lutea species on the available phosphorus or on the total exchangeable acidity. On the other hand, analyzing soil samples under Markhamia lutea showed an increase in the total nitrogen and a decrease in the pH and available phosphorus. Conclusion: Trees affect the chemical properties of soils. Therefore, it is recommended that under acidic soils, for example, forestry and agroforestry actors should use less acidifying tree species, such as Markhamia lutea and Podocarpus falcatus.

Effects Of Land Use

The aim of this research is to examine the response of some soil properties to the changes in land cover/land use in Gbonyin Local Government Area of Ekiti State, Nigeria. Land use changes as a result of human activities have been identified as one of the greatest pressures to soil and forest resources. The change from natural vegetation land use to built-up and agricultural land uses is becoming rampant in Gbonyin Local Government Area of Ekiti State, Nigeria. The objective of this study was to examine the effects of land use change on the some soil properties. Two major land use types which include forest lands and residential lands uses were explored. Soil samples were collected at the depth of 0 on 30cm through the use of soil auger from ten different locations in each of the two land use types in the study area making twenty soil samples. The use of t-test statistical tool was implored on the laboratory results in order to test for the differences between the soil in forest and residential land use types. Results revealed that the soil physico-chemical properties differed significantly between the sites. Chemical properties of the soil were found to be generally low in residential land use while they were high in vegetation land use. Bulk density was high in residential land use while it was low in forest land use.

Soils as a significant ingredient of terrestrial ecosystems are extremely important in agriculture field. Soil having different physical, biological, chemical properties. Physicochemical soil properties are the basic indicator of soil efficiency, it is strongly related to agronomic output. Soil parameters are very important in soil fertility that helps for plant growth as well as production. The soil quality is uniformly important as crop invention. The primary goal of this research is to use remote sensing techniques to evaluate soil properties. This goal is satisfied by emerging soil analysis on the basis of spectral data collected by FieldSpec4 spectroradiometer. The spectral analysis technique includes soil samples preparation, acquisition of spectral signatures and selection suitable statistical method. In this regard, soil properties and their consequent soil spectral signature measure. Statistical mean and series of processes are performed using View Spec pro Software. In the collected soil samples, surface soil parameters are more reflected than subsurface soil parameters. The spectral reflectance data can be alternative to the traditional methods for determining soil properties.

Fluvisols in urban wetlands in Bamenda Municipality Cameroon play a vital role in vegetable production but they are under immense pressure. Seven representative soil profiles and 21 surface soil samples were morphologically and/or physico-chemically characterized to classify the soils, evaluate their agro-utilization constraints, and to provide adequate data for planning sustainable land management. The soil samples were analyzed using standard procedures. Critical levels established for tropical crops and vegetables were used to declare deficiency of soil nutrients. The coefficient of variation were used as an index of soil variability, while sources of soil variation and subsequent grouping into management units were identified using principal component analysis. The soils, classified as Humi-umbric fluvisols are developed from young alluvio-colluvial material of granitic origin. Like other physico-chemical properties, organic matter varied irregularly down the profile. Except of pH which was slightly (CV<15%) variable, most soil properties were moderately (CV=15-35%) to highly (CV>35%) variable. Some correlation coefficients between the soil parameters were highly significant (p<0.01) ranging - 0.95 to 0.99, but most of them have correlation values less than 0.5. Six principal components (PCs) grouping soils in management units explained 96.2% of the variations observed in the soil properties. The PCs were: base status, organic matter, weathering and moisture retention, acidity, dispersal and N-mineralization, and mineral neo-synthesis factors. We recommend that a detailed mapping of soil properties be carried out for the establishment of a soil fertility map; and individual soil management practices defined for identified units instead of a common management for all units in the municipality.

This paper is focused on the Jizera Mountains as a region strongly influenced by man in the past. The structure of the natural forest was changed. Species monocultures with similar tree ages were planted. High acidificants concentrations in atmosphere led to the decline of these monoculture forests in the top parts of the mountains and the high acidificants deposition damaged the soils in the whole region. The goals of this study are to describe the distribution of the soil properties in altitude transects, where temperature, precipitation, and vegetation gradients are recorded, and to compare the soil properties in spruce and beech forests. The soil samples were collected from soil pits in a surviving nature-close beech forest, in a production spruce forest, and also in the top dead forest area with a grass cover. Soil samples from sufficiently deep diagnostic horizons were taken for the study of chemical properties. The basic soil characteristics were determined by the commonly used methods (pH, effective cation exchange capacity &minus; eCEC, and the contents of cations in the sorption complex, A<sub>400</sub>/A<sub>600</sub> as humus quality parameter, the contents of available Ca, Mg, K and P, pseudototal content of Ca and Mg, and two differently extracted Fe and Al forms contents). The soils of the Jizera Mts. are strongly acid with a low eCEC which is the result of the natural and anthropogenic acidification processes. Soil chemical properties of the most affected top mountainous parts are in some aspects more favourable than lower parts (binding of potentially toxic Al in organic matter, slightly higher pH), but in other aspects they are still endangered by the acidification symptoms (higher leaching of base cations, especially Mg). The soils of nature-close beech forests represent more favourable soil properties than those of planted spruce forests. Generally, it can be concluded that the natural systems have higher resilience, and that natural mechanisms are able to mitigate slightly the soil degradation.
