A study was conducted to determine the status of soil properties after enrichment planting in comparison to an adjacent secondary forest and to evaluate the effect of enrichment planting of Shorea macrophylla (de Vriese) on the soil fertility status with special reference to Soil Fertility Index (SFI) and Soil Evaluation Factor (SEF) at Sampadi Forest Reserve, Sarawak. The study sites were stands rehabilitated in different years (1996: SM96; 1997: SM97; 1998: SM98; 1999: SM99) and secondary forest (SF). Findings indicated that the soils at rehabilitation sites and SF were strongly acidic in nature, with pH less than 5.50, poor soil exchangeable bases, and nutrient status. The soils were relatively of sandy clay loam to sandy clay. Principal Component Analysis revealed the three most significant components of the soil properties which explained 76.3% of the total variation. At surface soils, SFI was correlated with tree growth parameters of S. macrophylla, indicating that SFI is an applicable soil quality index as compared to SEF. Notwithstanding, a significant association was found between soil available phosphorus and planted S. macrophylla, indicating that soil phosphorus is a better indicator than SFI. Further studies on other environmental factors influencing tree growth performance, early establishment of experimental reforestation at nursery, and field should be implemented to obtain the initial data on seedling growth performance prior to outplanting.

Provenance Variations

Indigenous tree species like Terminalia ivorensis has multiple uses; from timber products to medicinal condiments for treating different ailments. This species is self-incompatible. Thus, habitat protection is a key to its survival and sustenance. This study evaluated the effect of provenance variations on the growth and development of T. ivorensis. Three provenances of T. ivorensis were selected; FRIN Arboretum, Onigambari Forest Reserve and J1 Forest Reserve. Thirty (30) seedlings of T. ivorensis were selected and marked at each provenance for assessment of growth parameters for a period of twelve weeks. The growth parameters included: seedling height, collar diameter, leaf count and leaf area. Also, soil samples were collected from each provenance to test for nutrient composition. Results showed that J1 Forest Reserve had best performance across the growth parameters assessed with 10.4 cm plant height, 2.02 mm collar diameter, 11 leaves count and 20.5 cm2 leaf area respectively. This growth parameter result differs significantly from the other two provenances. This was also attributed to the nutrient offered by J1 Forest Reserve with 1.18% and 2.20% of organic carbon and organic matter in the soil respectively. Also, the available phosphorus which is involved in photosynthesis, respiration, energy storage and transfer, cell division and enlargement as well as promotion of root formation was about 15.7 mg/kg in the soil and is considered high because it is higher than the critical level of 8.50mg/kg. J1 Forest Reserve is recommended as the best provenance for raising T. ivorensis amongst assessed natural habitats.

Enrichment Planting

Deforestation leads to the deterioration of soil fertility which occurs rapidly under tropical climates. Forest rehabilitation is one of the approaches to restore soil fertility and increase the productivity of degraded areas. The objective of this study was to evaluate and compare soil biological properties under enrichment planting and secondary forests at Tapah Hill Forest Reserve, Perak after 42 years of planting. Both areas were excessively logged in the 1950s and left idle without any appropriate forest management until 1968 when rehabilitation program was initiated. Six subplots (20 m × 20 m) were established within each enrichment planting (F1) and secondary forest (F2) plots, after which soil was sampled at depths of 0–15 cm (topsoil) and 15–30 cm (subsoil). Results showed that total mean microbial enzymatic activity, as well as biomass C and N content, was significantly higher in F1 compared to F2. The results, despite sample variability, suggest that the rehabilitation program improves the soil biological activities where high rate of soil organic matter, organic C, N, suitable soil acidity range, and abundance of forest litter is believed to be the predisposing factor promoting higher population of microbial in F1 as compared to F2. In conclusion total microbial enzymatic activity, biomass C and biomass N evaluation were higher in enrichment planting plot compared to secondary forest. After 42 years of planting, rehabilitation or enrichment planting helps to restore the productivity of planted forest in terms of biological parameters.

Essential Information

Abstract Surveys of soil fertility and quality provide essential information, at multiple scales, for policy and management decisions on agricultural and environmental questions. Such surveys are expensive, and national-scale agricultural or geochemical surveys are conducted infrequently by public sector organisations. Where resources are scarce, the costs of management, sample collection, analysis, and data management can be prohibitive. This is likely to create a particular barrier to understanding how soil fertility may influence crop production in contexts where small-scale production is prevalent. Private sector soil laboratories conduct soil fertility analyses on thousands of samples annually: samples are often collected in a systematic way by experienced technical staff. The simple step of collecting location coordinates can greatly extend the utility of the data, beyond the immediate value to the farmer and without an added burden on them. Here we use a dataset of soil organic matter (SOM), plant-available phosphorus (P) and exchangeable potassium (K), from c. 27,000 georeferenced sample points collected in 2014-2017 in Pakistan by Fauji Fertilizer Company (FFC). Geostatistical methods are used to model the spatial variation of these soil properties and predict their values at unsampled locations. The geostatistical model allows the probability that soil properties fall below recommended thresholds for wheat production, and these probabilities are displayed as maps using "calibrated phrases" for probability ranges in the legend. The resulting maps provide a comprehensive overview of key agronomic data across ~194,000 km2 of cropland, realised as a direct consequence of sample location data collection being implemented by FFC. There is spatial structure in the SOM and K data, but not in the P data. These maps can be used to educate agronomists and farmers about typical soil fertility conditions in their region, and where soil analysis is a priority. They can also support more strategic planning of fertiliser needs in Pakistan where widespread nutrient deficiencies are found. This research demonstrates the potential for this approach to be used in many wider geographic contexts where there are few data from one-off survey activities. Additional benefits address concerns about data privacy have thus far limited their integration into a spatially disaggregated output that could benefit wider society.

Significant Difference

This study was conducted in 2019 to compare the growth performance and soil quality of two agesequences of Gmelina arborea plantation within the premises of the University of Port Harcourt, Nigeria. Data were collected from two stands of G. arborea established in 2011 and 2015. Growth performance was evaluated based on tree growth variables and above-ground carbon stored. Tree growth variables estimated were total height (TH), diameter at breast height (DBH), crown height (CH), crown diameter (CD) and merchantable height (MH). Topsoil (0 – 30 cm) samples collected from the two sites were analyzed for particle size distribution, organic carbon (OC), total nitrogen (TN), available phosphorus (Av.P), exchangeable bases (Mg, Ca, K and Na), exchangeable acidity (Al+ H+), effective cation exchange capacity (ECEC), base saturation (BS), pH, Manganese (Mn), Iron (Fe), Copper (Cu) and Zinc (Zn). The above-ground biomass (AGB) and carbon stock (CS) were also determined. T-test was used to test for significant difference in the measured parameters between the two age-sequences of G. arborea. Higher values for TH, DBH, CS and MH were recorded for the older stand although the differences between the two age-sequences were not significantly different (p ≥ 0.05). The AGB and CS per hectare were higher for the older than the younger G. arborea stand (302.27 m3 ha-1 and 151.52 m3 ha-1, respectively). Higher values for silt, clay, Ca, Mg, Al+ H+, ECEC, BS, Mn, Fe and Zn were also recorded for the older stand. However, the observed differences were only significant (p < 0.05) for clay, pH, Av.P, Mn and Fe. The study revealed that although soil properties, tree growth as well as carbon sequestration capacity of G. arborea stand improved/increased with age, the differences were mainly not statistically significant (p ≥ 0.05) between the two (eight and four years) age-sequences.

The experiment was conducted on abandoned agricultural land at Bena-Tsemay District, Southern Ethiopia. It was designed to evaluate legume shrubs growth performance, and its potential for soil fertility enhancement through improved fallow practice. The results of the current study showed that the growth performance of legume species reveals variation in different growth parameters. The mean height of Sesbania sesban was significantly higher than the other species except for Senna siamea. Senna siamea recorded the highest mean stem diameter followed by Sesbania sesban, 3.47 cm, and 2.86 cm, respectively. Legume shrub species for soil fertility enhancement under improved fallow showed an increase in soil pH, organic carbon, organic matter, phosphorus level, available potassium, and total nitrogen during the growth period. Sesbania provides a large amount of nitrogen (2.91 t ha- 1) within two years fallow period, linked with the carbon to nitrogen ratio (11.22) having better mineralization potential. The growing of promising legume shrub species as an improved fallow practice has an important contribution in the restoration process of abandoned agricultural land and used as an option to grow crops in a rotational cropping system.

Abstract. Adanan IC, Wasli ME, Perumal M, Ying HS. 2020. Characterization of soil properties in relation to Shorea macrophylla growth performance under sandy soils at Sabal Forest Reserve, Sarawak, Malaysia. Biodiversitas 21: 1467-1475. A study was conducted in the Sabal Forest Reserve, Sarawak, to characterize soil properties in terms of soil morphological and physicochemical properties under sandy soil at the reforestation site in comparison with High Conservation Forest soil as well as to assess growth performance of planted S. macrophylla under the sandy soil. Study sites with the size of 25 m x 25 m were established under reforestation sites (Early Establishment of Reforestation Site (ER) and Late Establishment of Reforestation Site (LR)) as well as the High Conservation Forests (HCF-1 and HCF-2). The results from soil morphological properties showed that the soils in ER and HCF-2 plots resemble Saratok series while soils in LR and HCF-1 plot were classified into Buso series. As for soil physicochemical properties, soil in all study sites were strongly acidic in nature with pH (H2O) value less than 5.00 with sandy (more than 55%) at both surface and subsurface soil. The survival percentage of planted S. macrophylla in ER and LR plot was 65 % and 56%, respectively. Long term monitoring on soil properties and growth performance of planted S.marophylla tree are essential in order to continuously provide information on the status of reforestation activity.

Implementation of effective soil conservation management is required in order to rehabilitate and manage degraded forest land in the tropics. For the humid tropics of Sarawak, Malaysia, extensive information on the soil characteristics for rehabilitation of degraded forest lands is essential to guide future forest management programme. In this study, a preliminary assessment on the current status of the soil morphological and physicochemical properties at one of the reforestation sites in Sarawak which was established after enrichment planting of Shorea macrophylla in comparison to an adjacent secondary forest was conducted. The soil profiles in the study sites were established at the reforestation areas of different age stand (year 1996; SM96, 1997; SM97, 1998; SM98 and 1999; SM99) planted with Shorea macrophylla located in Sampadi Forest Reserve as well as existing secondary forest adjacent to the reforestation sites (secondary forest, SF). Soil profile description was conducted at each study sites and soil samples were collected from each identified soil horizon for determination of the soil physicochemical properties. The results showed that the soils in the study area consisted of mainly grey-white podzolic soils which derived from combination of sandstone, coarse-grained, humult ultisols and sandy residual parent material. According to the Sarawak Soil Classification, the morphological properties in the studied sites resemble of Bako soil series as a dominant unit in association with Saratok series in which, corresponds to Typic Paleaquults of Soil Taxonomy by USDA-NRCS Classification. The general soil physicochemical properties indicated that the soils at both reforestation sites and secondary forest were strongly acidic in nature with pH (H2O) of less than (pH < 5.5) with low nutrient status. The acidic nature of the soils might be ascribed to the presence of high exchangeable Al which concomitantly, increased the level of Al saturation of the studied soils. Observation within each soil profiles indicated that soil acidity decreased with depth, resulting in higher pH (H2O) at deeper horizons for all studied sites. For the soil total carbon and total nitrogen, soils at secondary forest depicted higher values in total carbon and total nitrogen at surface soils as compared to the reforestation sites which indicate large pool of organic matter at surface soil derived from the above vegetation. In terms of the soil physical properties, the soils observed were relatively of sandy texture and did not varied widely among the studied sites. In addition, the soil bulk density at reforestation sites was relatively higher than secondary forest due to higher penetration of roots and accumulation of organic matter contents in secondary forest. Based on the current progress of this study, it is recommended that determination on the soil characteristics should be taken into consideration as an important indicator prior or during the establishment of reforestation area in order to ensure the success of reforestation activity in tropical rainforests.

AbstractMonitoring the temporal and spatial variation of soil properties is helpful to understand the evolution of soil properties and adjust the management method in time. Soil fertility evaluation is an urgent need to understand soil fertility level and prevent soil degradation. Here, we conducted an intensive field investigation in Chinese hickory (Carya cathayensis Sarg.) plantation to clarify the spatial and temporal variation of soil properties and its influencing factors, and to evaluate the change of soil fertility. The results showed that the soil pH and soil organic carbon (SOC) significantly increased from 2008 to 2018, while available nitrogen (AN) significantly decreased from 2008 to 2018. The semi-variance revealed that except available phosphorus (AP), the spatial dependencies of soil properties increased from 2008 to 2018. An increasing south-north gradient was found for soil AN, AP, available potassium (AK) and SOC and a decreasing south-north gradient was found for soil pH. The average soil fertility in the whole area was increased from 2008 to 2018. Our findings demonstrated that the changes of the management measures were the reason for the change of soil properties from 2008 to 2018. Therefore, rational fertilization strategies and sod cultivation are recommended to maintain the long-term development of the producing forest.

The present study investigated the combined effect of rice husk dust (RHD) (0.1.2.3.4 and 5 ton ha-1) and NPK 10:10:10 fertilizer (0, 1, 2, 3, 4 and 5 ton ha-1) arranged factorially in Randomized Complete Block Design(RCBD)on selected soil fertility indices (pH, organic carbon, organic matter, total nitrogen, available phosphorus, exchangeable bases, exchangeable acidity and effective cation exchange capacity) and growth parameters of Jatropha (number of leaves, plant height, number of branches and stem girth) in an ultisol of southeastern Nigeria. Results showed significant (P<0.05) improvement in all soil chemical properties and growth parameters of plant compared to control which had no treatment. However, the effects varied with treatment levels and interactions. While the effects increased with rate of application, interactions consistently showed superior effect on all parameters studied. Thus, combining rice husk dust (RHD) and NPK may increase the soil fertility and growth of Jatropha. Treatments combination of5tonha-1 RHD and 3tonha-1 NPK and 5tonha-1 RHD and 5tonha-1 NPK relatively gave the most appreciable result in soil chemical properties and growth of Jatropha respectively, thus are recommended.
