Research ArticleOpen accessIn the keywordsEffects of Land Use Practices on the Organic Carbon Content, Cation Exchange Capacity and Aggregate Stability of Soils in the Catchment ZonesMosayeb Heshmati, Arifin Abdu, Shamshuddin Jusop, Nik Muhammad MajidProblem statement: Land use practice leads to changes in the physico-chemical properties of soils, such as Soil Organic Carbon (SOC), Cation Exchange Capacity (CEC) and Soil Aggregate Stability (SAS) that cause soil erosion. Approach: Merek catchment, Iran suffers from land degradation due to poor land use practice. A study was carried out with the objectives: (i) to determine soil nutrient … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 25 Oct 2011 · 8,722 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparing the Fertility of Soils under Khaya ivorensis Plantation and Regenerated Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem statement: It is widely accepted that conversion of natural forest to other land use types leads to deterioration of soil fertility and increased soil compaction which consequently become degraded secondary forests. Degraded secondary forest or forestland is indicated by low in soil fertility and organic matter due to imbalance input and output from original vegetation. Forest plantation through planting … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,509 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Selected Soil Chemical Properties of Two Different Mangrove Forests in SarawakEmpi Rambok, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Despite few studies of forest health and environmental conditions of mangrove forest in Sarawak, the data was not sufficient to facilitate baseline data and direct comparison of mangrove forest health obtained for different location of mangrove forest in Sarawak. On this regard, determination of contemporary mangrove soil condition was essential to addressing mangrove forest for forest health, carbon … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 9,648 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDifferences in Soil Physical and Chemical Properties of Rehabilitated and Secondary ForestsM. H. Akbar, O. H. Ahmed, A. S. Jamaluddin et al.Problem statement: The soil properties of tropical rain forest in Southeast Asia have been characterized by several researchers; however empirical data on soil characteristics under rehabilitation program are still limited or even lacking. This research is important to determine the soil physical and chemical properties of a rehabilitated degraded forest land 19 years after planting with various indigenous species in … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 12,545 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Selected Chemical Properties of Peat Swamp Soil Before and After Timber HarvestingMuhamad Ismawi Salimin, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Peat swamp is an important component of the world’s wetlands. Once they are disturbed the tendency for the soil degradation is very high. This study compared selected chemical properties of a peat swamp soil before and after timber harvesting. Approach: Peat soil samples were taken at 0-15 cm depth in 6 plots with 0.1 ha each plot at … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 8,786 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Different Ages of a Rehabilitated Forest on Selected Physico-chemical PropertiesRajeswari A.P. Murugayah, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: This research was important because of still lack of information about rehabilitated tropical forest age effect on infiltration rate. The objectives of this study were to determine the influence of age of forest on soil water infiltration rate and to evaluate the influence of forest age on the relationship between water infiltration rate, soil organic matter and soil … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOff-road Vehicle-Induced Substrate Vibrations Are Associated with Strong Declines in Ectomycorrhizal Mushroom Fruiting in Forest EcosystemsLev ShestakovWe conducted a multi-year (2020-2024) control-impact field study in a pine forest of the Moscow Region to assess whether off-road vehicle activity affects the fruiting of two ecologically important ectomycorrhizal fungi, Boletus edulis and Suillus luteus. Substrate vibrations associated with vehicle passage were recorded and characterized by dominant energy in the low-frequency range. Over the study period, abundance in disturbed … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 23 May 2026 · 1,305 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRelationship between Laboratory Germination and Biometric Parameters of Betula jarmolenkoana Golosk. AgletsZhandos Rakymbekov, Kurmankul Abayeva, Daniyar Dosmanbetov et al.This study evaluates the relationship between laboratory germination and biometric parameters of aglets of the critically endangered birch tree species Betula jarmolenkoana Golosk (Yarmolenko birch). The Yarmolenko birch is a very rare, narrowly endemic species, growing at an altitude of 1,900-2,100 m above sea level and only in the basins of three rivers (Kakpak, Bayynkol, and Tekes) in the Almaty … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 1 Mar 2023 · 4,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hybrid Machine Learning Approach to Predictive Analytics in Precision Agriculture for Sustainable Crop OptimizationJignesh Kariya, Pankaj MudholkarDriven by data-enabled technologies, precision agriculture is evolving into an innovative way to increase agricultural productivity and sustainability. Conventional agricultural practices face several challenges, such as poor soil quality, inappropriate crop selection, improper resource utilization, and unpredictable climate conditions. To address these limitations, this paper proposes a hybrid machine learning framework for sustainable crop optimization and predictive analysis in precision … …Journal of Computer Science, Vol. 22, Issue 10 · 10 Oct 2026 · 865 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Crop Yield Detection and Prediction With Multimodal Data Using Fusion TechniquesKutlwano Sedimo, Rajalakshmi Selveraj, Venumadhav Kuthadi, Thulaganyo DimakatsoMost often, soil, environmental, and agronomic data are used in pieces, hence limiting the performance of crop selection and yield forecasting. This study develops an integrated, fusion-based framework that combines soil image classification, environmental feature analysis, and input-driven yield prediction to support precise agricultural decision-making. The system consists of three major modules: (i) a CNN for the classification of soil … …Journal of Computer Science, Vol. 22, Issue 10 · 5 Oct 2026 · 481 accessesView PDFCite
