“…In assessing the role of soil P fractions to tree nutrition in a short-term experiment, Niederberger et al (2017) found poplar trees to decrease readily and moderately labile P fractions, thus showing the importance of these fractions in tree nutrition. It has also been shown that pine, eucalyptus and cypress trees decrease organic P content and, utilize even non-labile P due to enhanced enzymatic activities, mycorrhizal associations as well as changes in soil pH, which enhances P mineralization (Chen et al, 2008;Gatiboni et al, 2017). Phosphorus is mainly recycled into the soil through litterfall in forests (Qiong et al, 2008) hence litter input and quality greatly influence P concentration in forest soils.…”

“…However, the tendency to exploit more forest lands to increase the overall agricultural production could have negative effects on soil fertility and biodiversity due to alteration of soil properties and reduction in soil organic matter content (de Graaff et al, 2019;Tolimir et al, 2020). Reduction in soil organic matter content, for instance, causes a collapse in soil structure and a weakening of soils' capacity to retain nutrients (Qiong et al, 2008;Gatiboni et al, 2017).…”

Background: Forest conversion to other land use types lead to changes in soil physico-chemical properties and a reduction in soil fertility. Although forest conversion is extensively recognized to alter soil properties, the influence on distribution of soil phosphorus (P) fractions and abundance and diversity of soil biota is not well explored. Objective: To assess the effects of converting undisturbed natural forest to plantation forest (cypress), grazed pastures and potato fields on soil phosphorus (P) fractions and abundance and diversity of arbuscular mycorrhizal fungi (AMF) in Nyandarua County, Kenya. Methodology: Transects laid out in triplicate were established in each land use type. In potato fields and grazed pastures, transects measured 50 m with three sampling points established 15 m apart along each transect, each point measuring 1 m² divided into 25 grids with each grid being 400 cm². Transect length was increased to 150 m in forest sites due to relatively larger size of the area studied and sampling points were placed at 50 m apart, each point measuring 25 m² and divided into 1² m grids. Soil and plant samples were randomly collected from sampling points and were used to determine chemical properties, soil P fractions and AMF spore examination. Data were analyzed by analysis of variance (ANOVA). Results: Soil chemical properties were significantly (p<0.001) higher in natural forest compared to potato fields, grazed pasture and cypress forest. On the contrary, readily labile and moderately labile P was higher in fields cultivated with potato (125.3 mg and 258.2 mg P kg-1, respectively) than in natural forest (51.1 mg and 95.3 mg P kg-1) and cypress forest (36.4 mg and 82.7 mg P kg-1, respectively). However, non-labile P was higher in natural forest (599.1 mg P kg-1) and lower in cypress forest (251.3 mg kg-1). Of the ten AMF genera identified, only Glomus and Acaulospora were significantly (p<0.01) affected by land use change, where they were more abundant in fields cultivated with potato than the other three land use types. Land use type did not significantly influence diversity and richness in AMF. However, AMF composition varied across the land use types. Implication: Land use change may negatively affect soil chemical properties, enhance redistribution of soil P, and change AMF community composition, and this could have long-term implications on soil fertility. Conclusion: Land use change from natural ecosystems to croplands, grazed pastures and tree plantations alter soil chemical properties, AMF composition and spore abundance, and redistribute soil P fractions by increasing labile P and reducing non-labile P fractions showing that the type of land use chosen significantly influence soil physical and chemical properties and soil biodiversity.

“…Some researchers have evaluated responses to management practices using improved genetic material, mechanical site preparation, control of competing vegetation, and fertilization in Pinus plantations, and found positive results in the relationship between productivity and soil chemical attributes, significantly improving the growth of species when best tillage practices were recommended (Albaugh et al 2010, Batista et al 2015. Other studies have reported that successive cycles of Pinus plantations without nutrient replacement tend to cause a nutritional deficit for the trees, resulting in low productivity in forest plantations (Gatiboni et al 2017, Gatiboni et al 2020). Therefore, assessing soil microbiological attributes and their relationships with chemical and physical soil characteristics, combined with site-specific silvicultural management practices in Pinus taeda, provides a better understanding of soil nutrient dynamics (Sixel et al 2015, Tulio et al 2022.…”

Over the last decades, Pinus taeda L. plantations in southern Brazil showed a great increase in average production. However, the gains in productivity obtained by genetic selection and breeding have nowadays stabilized. Research on edaphic factors and silvicultural practices is currently performed with the aim of both increasing the productivity of P. taeda plantations and maintaining the soil quality. To this end, soil microbiological attributes are considered better indicators of soil quality as they are more sensitive than chemical and physical ones. In this study, we aimed to evaluate the relationship between microbial activity and the physical and chemical parameters of different soil types under young Pinus taeda plantations at five different sites in southern Brazil. Soil samples were collected at depths of 0-5 and 5-10 cm. The soil microbiological attributes evaluated were: potentially mineralizable nitrogen (PMN), microbial biomass carbon (MBC), microbial biomass nitrogen (MBN), microbial basal respiration (MBR), and metabolic quotient (qCO2). We also evaluated some physical and chemical soil parameters. Sites with the highest values of C, clay, and nutrients in the soil, showed higher values for the soil microbiological attributes, compared to the other study sites. The previous management with minimal tillage in some sites seems to positively affect soil quality. The MCB and MBR showed better sensitivity in indicating differences between sites and showed a good relationship with clay content, C/N ratio, K, and pH. These results suggest that site-specific characteristics such as soil type or forest management influence soil microbiological attributes in Pinus taeda plantations during initial growth in southern Brazil.

“…In southern Spain, on calcareous Vertisols and related Inceptisols, labile P can be predicted in practice using P tests and extractable Fe values [14]. The type of land use and management of P also affect the availability of P. Continuous cultivation of plants on humic cambisol without fertilization can lead to a decrease in the availability of phosphorus (P) in the soil [15]. Land use shift from forest to pasture for extensive pastoralism in the Colombian Amazon resulted in a 31.1% decrease in labile inorganic P fractions, with mineralization of organic P by the enzyme phosphatase playing a significant role in P availability [16].…”

In most cases, the irrigated soils of Uzbekistan provide low forms of phosphorus assimilated by plants due to their high fixation. Therefore, the bioavailability of P is one of the main factors limiting the yield of crops. The study aimed to identify the transformation of phosphorus in irrigated gray soils under the influence of the type of land use, age of development, and climate (location above sea level). For this purpose, the content of inorganic and organic pools of P was studied according to the Hedley method. The highest Pt values were noted in the soil of the Parkent region, where the amount of precipitation significantly exceeds that in other studied areas, as well as in the winterwheat-repeatedcrops-cotton (WW-RC-C) land use type with long-term use of high P fertilizer rates. In the studied soils, the share of Pi was 89-91%, while the share of Po was 9-11% of Pt. In the accumulation of labile P, in contrast to the accumulation of Pt, the greater availability of atmospheric precipitation and the WW-V type of land use, where the content of labile P. was significantly higher than in other studied soils. The obtained results indicate the need for individual consideration of the control of phosphorus nutrition of plants on soils used in various types of land use, their geographical location (altitude above sea level), and the age of development for agriculture, depending on the phosphate state of soils.
