    Land Consolidation with Seedling Cultivation Could Decrease Soil Microbial PLFA Diversity

    Shen Zhang1, Yongqi Jian1, Bingjing Yan2, Jin Jin1, Jiasen Wu1, Chenfei Liang1, Juan Liu1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.8, pp. 1745-1756, 2022, DOI:10.32604/phyton.2022.021076

    Abstract The impact of land consolidation on the soil microbial PLFA diversity is of great importance for understanding the effective arable land usage, improving agricultural ecological conditions and environment. In this study, we collected the soil samples (0–20 cm) in experimental plots with 0 (Z0), 1 (Z1a) and 4 (Z4a) years of land consolidation in the forest station of Ningbo City, Zhejiang Province, southeastern China. The results were analyzed using ANOVA for randomized block design. Compared with control (Z0), the soil pH value under Z1a treatment increased by 14.6%, soil organic carbon (SOC) content decreased by 65.4%, so did… More >

    Potential risk of biologic pollution associated to the introduction of Pinus radiata in grassland areas

    Garay MM1, NM Amiotti2, P Zalba1

    Phyton-International Journal of Experimental Botany, Vol.84, No.2, pp. 280-287, 2015, DOI:10.32604/phyton.2015.84.280

    Abstract Afforestation is a recommended practice to mitigate global warming. However, their implementation may generate undesirable impacts, mostly if exotic species are used. Plantations of Pinus radiata D Don in Ventania (Bs. As., Argentina) soils showed notorious increments of extractable P (Pe), which could affect the dynamic of this element as well as the degree of phosphorus saturation (GSPBray). The objectives of this study were: i) to quantify the GSPBray in Mollisols afforested with P. radiata comparing the results with those coming from adjacent, natural grassland areas (base line); ii) to evaluate the potential environmental risk induced by afforestation… More >
