“…Jony azotanów (V) i azotanów (III) uznawane są za jedne z najgroźniejszych czynników, które mogą wywierać wpływ na zdrowie ludzi i zwierząt. Są one łatwo rozpuszczalne w wodzie i nie ulegają procesowi sorpcji w glebie, mogą zatem przenikać do wód gruntowych [Jones 2012, McCarty 2003]. …”

“…In addition, roots absorbed water and enabled the plant to maintain its turgidity. Furthermore, soils with high organic matter content and cation exchange capacity (CEC) cause mineral elements in soil to be transferred or absorbed by the roots, especially potassium (K) (Jones and Jacobsen, 2005). …”

The underutilized and improper management of wastewater such as palm oil mill effluent sludge (POME) sludge might create pollution and give a negative impact towards the environment. This study was aimed to evaluate the effect of shear strength parameter and root length density of maize on Entisols applied with POME sludge as a soil amendment. The maize was planted on Rasau soil series (Entisols) amended with different POME sludge treatment systems from various ponds (mixing, anaerobic, facultative, algae, and dumping). Standard direct shear box test was used to identify the cohesion (c) and angle of internal friction (ϕ) after application of treatments. The bulk density, porosity, moisture content, organic matter, root length and root density of Zea mays L. (Hibrimas) applied with POME sludge from dumping pond (DP), aglae pond (ALP) and facultative pond (FP) were significantly difference against the control treatment. The positive effect of root length and root length density (RLD) treated with POME sludge from the dumping pond was 26% and 38% compared to the other treatments. The results highlighted that roots enhanced soil shear strength by reducing the cohesion and increased the angle of internal friction component.The shear strength analysis showed that high shear strength of normal stress at 500.72 kN/m 2 was measured from the dumping pond's POME sludge treatment after maize harvesting. The POME sludge from the DP, ALP and FP was ameliorating some nutrients deficiencies for the plant growth and improved the root length density. In conclusion, the POME sludge from the DP indicated the high shear strength and root length densitie due to the adequate nutrients for roots distribution and maize growth.Keywords: Shear strength, root length density, Entisols, POME sludge IntroductionMaintaining and replenishing organic matter into the soil is important to sustain the productivity of the soil in the tropical climate. Generally, Malaysia had produced about half of organic waste from oil palm industry, which has not been fully utilized. According to Embrandiri et al., (2013) palm oil mill effluent (POME), palm kernel cake, decanter cake, empty fruit bunch and palm kernel shell were potential to be processed and used as an organic matter amendment for land application. Recently, some studies were using decanter cake with lady's finger (Embrandiri et al., 2013), tannery sludge with capsicum plants (Silva et al., 2010), cowpea and olive mill waste with lettuce and chicory (Kelepesi and Tzortzakis, 2009) as their organic matter materials for soil amendment. Unfortunately, only a few studies were focused on POME sludge as a soil amendment for the plant growth. According to Khairuddin et al., (2016), the treated POME sludge was identified equally balance with C, N, and macronutrients (P, K, Ca, Mg, S, Na). Mostly, these elements were vital for soil improvement and productivity of the crops. Moreover, heavy metal content in POME sludge was in accordance with the standard from WHO/FAO that is safe for human consu...

“…Clay is generally considered as the active part of soil because it plays a role in the supply and availability of nutrient elements [35]. The impact of edaphic heterogeneity on species assembly has been reported in rainforests of the Congo Basin, where differences in soil texture (clayey versus sandy soils) considerably influence biodiversity and habitat preference [2] [36] [37].…”

One of the problems limiting high survival rates of Pericopsis elata (afrormosia, assamela), a high value timber species, is lack of data on its pedological requirements. A study was conducted in the East Region of Cameroon to identify possible soil properties favoring its spatial distribution. Two test areas, in and out of a Pericopsis elata natural forest stand were identified and in each sampling units of 50 × 50 m delineated. Thirty eight and sixteen quadrats in and out of the stands were respectively sampled for soil physico-chemical properties, number of stems and diameter at breast height. Soil samples in each quadrat were analyzed following standard laboratory procedures. Soil properties were tested for normality and compared for the two sites using Student's t-test. Principal component analysis and correlation analysis were performed on tree and soil data to identify soil factors responsible for spatial distribution. From our findings, key soil indicators favouring Pericopsis elata distribution appear to be acidity (soil pH and exchangeable acidity), base status (base saturation and exchangeable bases) and texture (clay content). More specifically, optimal soil conditions for growth and survival of Pericopsis elata are: pH (4.1 -5.0), exchangeable acidity (<4.67 cmolc•kg −1 ), base saturation (6.2% -17.8%), and clay content (24.0% -49.0%), which should be considered in site selection for reforestation with Pericopsis elata.
