Twelve soil and twelve leaf samples were collected from twelve litchi (Litchi chinensis Sonn.) orchards from different locations of Dinajpur to evaluate some physico-chemical properties and nutrient status of soil, and concentration of nutrients in litchi leaf. The pH of the soil varied from very strong acidic to medium acidic (4.8 - 5.7), organic matter content varied from 0.84 - 1.88%, EC varied from 302.4 - 310.2 μS/cm. The dominant soil textural class was clay loam. The average particle density was 2.49g/cm3. Total N, P, K and S in soils were 0.053 - 0.180%, 0.02 - 0.07%, 0.046 - 0.370 meq/100 g, and 0.015 - 0.028%, respectively. Available N, P, K, S, Zn, Fe, Mn and B in soils 30.40 - 57.8 mg/kg, 10.53 - 14.33 mg/kg, 0.03 - 0.32 meq/100 g, 20.03-34.80 mg/kg, 0.68-1.50 μg/g, 31.8 - 41.5 μg/g, 6.75 - 7.39 μg/g and 0.25-0.51 μg/g, respectively. The concentration of total N, P, K, S, Zn and Mn in the leaf were 1.74 - 2.20%, 0.11 - 0.188%, 0.104- 0.198%, 0.129 - 0.430%, 12 - 14 μg/g and 30 - 74 μg/g, respectively. The overall results indicated that the fertility status of the soils under the litchi plantation in the Dinajpur area are medium fertile. So, farmers could be advised to grow litchi plants after applying amendments to the soils to improve the physico-chemical properties in the Dinajpur area of Bangladesh. Dhaka Univ. J. Biol.

Seasonally Flooded

The seasonally flooded soils of Bangladesh are unique in respect of several specific characteristics and contribute toward producing bulk of its staple food - mainly rice. Having fine texture these soils are similar to the “paddy soils” of Southeast Asian floodplains and have high production potential under proper management. Six representative soil series, viz. Arial, Debidwar, Naraibag, Jalkundi, Siddirganj and Tippera from the central region of Bangladesh have been studied to evaluate some of their intrinsic physico-chemical properties and their sustainable management requirements. These soils are slightly acidic to neutral and are negatively charged with ΔpH values ranging between –0.2 and –1.2. The organic matter content in the surface soil is relatively low that decreases steadily with depth. The cation exchange capacity (CEC) of the soils varies on the basis of their clay and organic matter contents while base saturation per cent (BSP) is high. The contents of available N, P, K and S and DTPA-extractable Fe, Mn, Cu and Zn in soils are moderate and are commensurate with the contents of colloidal fractions. These soils receive several mineral nutrients annually with the sediments deposited during the monsoon floods. The characteristics like organic matter content, particle size distribution, CEC, pH and BSP that have important management implications have been discussed.

Twenty soil and leaf samples from 20 orchards of mango (Mangifera indica L.) were collected from different locations of Rajshahi and Satkhira regions to evaluate soil texture, pH, organic matter, available and total nitrogen, phosphorus, potassium and sulfur of soils and the concentration of N and K in mango leaves. The pH of the soil varied from 6.3 - 7.9 and organic matter content varied from 0.72 - 3.60 per cent. The available nitrogen, phosphorus, potassium, and sulfur of the soils ranged from 190 - 510, 39 - 196, 36 - 206 and 25 - 235 mg/kg, respectively. The values of total N, P, K and S were 0.03 - 0.12, 0.022 - 0.210, 0.235 - 0.0.936 and 0.005 - 0.266 per cent, respectively. The dominant soil textural class was silty clay loam. The mean concentration of nitrogen (0.88%) and potassium (0.61%) in the leaf sample was low. The overall fertility status of the soils of Rajshahi and Satkhira regions in relation to mango cultivation is moderate. Dhaka Univ. J. Biol. Sci. 29(2): 155-163, 2020 (July)

In 12 astatic pools, each of which was characterised by the dominance of phytocenoses of one of three plant associations, investigations were performed on the physico-chemical properties of the water and bottom sediments, in order to establish the relations between the habitat conditions and vegetation. The criterion of the degree of saltiness of the bottom sediments and the specific conductivity of water in these water bodies allows to order them according to their decreasing fertility as follows: 1) water bodies with dominant phytocenoses of the association <em>Equisetetum limosi</em>, 2) with <em>Caricetum elatae</em>, 3) with <em>Typhetum latifoliae</em>. The type of vegetation indicates also connections with other properties of the water (hardness, oxidability, pH, chloride content) and of the bottom sediment (organic matter content, chlorides, magnesium and various forms of nitrogen). Correlation between the chemical composition of the water and depostis has only been demonstrated in the case of chlorides.

Soil is an important resource for production system but its productivity is declining day by day due to increasing degradation. The excessive use of fertilizers including agro-chemicals and water under monotonous cropping system to increase the food production, particularly in Indo-Gangetic Plain, resulted in detrimental effect on soil ecosystem (Jagdish Prasad 2004). To maintain the equilibrium in productivity vis-à-vis soil environment, it is necessary to periodically monitor the soil properties and nutrient availability. Soil testing provides information about nutrients availability in soil which forms the basis for the fertilizer recommendation for sustainable production (Doneriya et al. 2013). Present study was conducted to analyze the physico-chemical properties and nutrients in soils of an agriculturally important Harahua block of Varanasi district, Uttar Pradesh. Seventy five soils samples (0-15) were collected from Bhelkha (V1), Chamaon (V2), Koiran (V3), Bhawanipur (V4), Pissaur (V5), Daniyalpur (V6) and Ganeshpur (V7) villages of Harhua block of Varanasi district. Sorghum, pearl millet, maize, paddy, pigeon pea and green gram are major crops during kharif, while wheat, mustard, field pea, and potato are commonly grown in rabi season. Quartering technique was used for preparation of soil sample. The samples were air-dried and passed through 2 mm sieve for analysis. The soil pH and EC were determined with 1:2.5 soil water ratio. The soil samples were analyzed for sand silt and clay (Chopra and Kanwar 1999); organic carbon (Walkley and Black 1934); available N (Subbiah and Asija1956); available P (Olsen 1954); available K (Jackson 1973); available S (Hariram and Dwivedi 1994), bulk density, particle density and porosity following standard procedures. Porosity and nutrient index value (Ghosh and Hasan 1976, 1979 and 1980) were calculated by using the formulae. Porosity = (100 − BD/PD)×100 Nutrient Index Value = [(% soils high in available estimates of a nutrient × 3) + (% soils medium in available quantities ×2) + (% soils low in available quantities × 1)] ÷ 100 The soil pH varied from 6.1 to 8.5 (Table 1). About 57 % samples were neutral (pH 6.6 to 7.3), 29 % samples were mildly alkaline (pH 7.4 to 7.8) and 13 % samples were moderately alkaline (pH 7.9 to 8.4). The electrical conductivity of the soils varied from 0.22-0.47 dS m-1 and were found to be normal (EC < 1.0 dS m-1). The sand, silt and clay content of the soils varied from 31.1-52.1 %, 18-30 % and 18-35.2 % with mean values of 43.8, 23.6 and 26.1, respectively, with standard deviations of 6.35, 4.53 and 5.58. Bulk density and particle density ranged from 1.21-1.47 Mg m-3 and 2.00 to 2.77 Mg m-3. The porosity of the soils ranged from 27 – 57 % with mean value of 46.8 % and standard deviation of 5.88. According to Muhr et al. (1965) rating, the organic carbon content ranged from 0.30 to 0.75 % with an average of 0.63 % and standard deviation of 0.09. About 9 % samples had organic carbon content below 0.50 % and 90 % samples were between 0.50 - 0.75 %.

The Impact

Two field experiments were conducted in a calcareous soil during summer seasons of 2019 and 2020 at the experimental in a private farm Mallawi, El- Minia Governorate, Egypt to evaluate application of K fertilization at different rates of K2SO4 and non-classic products, i.e. K feldspar, mixture with or without inoculation with the K dissolving bacteria (Bacillus circulans.) soil chemical properties, plant growth, yield and nutritional value of corn (Zea-maize hybrid third 310). Our results proved that inoculation of maize seeds with Bacillus circulans at rate of 36% K2O improved soil pH, EC, soil organic matter content and enhanced the soil available N, P and K concentrations. Also, the growth parameters, yield and nutritional status of the plants were significantly increased by using non-traditional potassium fertilizers particularly in the case of seed inoculated with potassium dissolving bacteria (Bacillus circulans).

In the North Western Himalayas, particularly Jammu region, where 85% of people depend on agriculture and allied sectors, 70% of agriculture is rain-fed. Various factors, especially land use pattern and variations in climatic conditions affect the soil fertility and nutrient contents. However, information on essential nutrients in the soil across the region is meager. An attempt has been made to study the soil nutrient status under different agro-climatic zones of Jammu region. Seven hundred seventy surface soil samples (0-15 cm) from sub-tropical, intermediate and temperate zones of Jammu region were collected and analyzed for soil texture, pH, electrical conductivity (EC), organic carbon (OC), CaCO3, CEC, available macro nutrients (N, P, K, S) and micronutrients (Fe, Cu, Zn, Mn). The results indicated large variation within the soils of each zone. The amount of all the available nutrients was more in the soils of temperate zone than those of other zones. The soils of sub-tropical zones were low in available N, P, S and Zn and to some extent in K. Organic matter content, clay and silt content of the soil vis-à-vis cation exchange capacity were found to be the main factors controlling the available nutrient content of the studied soils.

Landuse change are suspected to be one responsible to soil fertility decline on Resapombo, Doko, Blitar. Efforts done by local farmers to deal with these problems are plantation of P. falcataria trough a reforestation program around 2011-2012. The benefits of the program are still need to be assessed so that this research was done (1) to compare the soil quality between P. falcataria-planted field and no P.falcataria field by the parameters of soil organic matter content and available N, (2) to study the relationship between organic matter input and soil organic matter content and available N, and (3) to identify factors affecting N availability post-P. falcatariaplantation. This research used randomized block design with 5 treatments (annual crop field, 3 and 6 years P. falcaria plantation field, agroforestry field with P. falcataria + coffee + talas plantation, and ex-P. falcataria-planted field. Soil were sampled compositely by 3 replication from 0-20 cm depth. Litter were sampled from a 0.5m2 sub-plot of each treatment. Results showed that P. falcataria plantations enhance soil fertility indicated by increased soil organic matter input to 10.6 times (monoculture) and 17.6 times (agroforestry) control, increased soil organic matter content by 1.5 times (monoculture) and 2.3 times(agroforestry) control, increased total N of 1.6 times (monoculture) and 2.4 times (agroforestry) control, increased ammonium by 1.7 times (monoculture) and 3.2 times (agroforestry) control, and increased nitrate by 2.4 times (monoculture) and 3.9 times(agroforestry) control.The increased soil N content of P. falcataria-planted field were caused by higher soil organic inputs compared to those with no P. falcataria plantation. Nitrogen availability affected by soil texture but have no relationship with soil pH. However, agroforestry fields showed higher pH, organic C, total N, and available N than monoculture P. falcataria fields. Measured soil chemical properties showed no significant change by the increase of P. falcataria age, moreover, they declined down towards control on ex-P. falcatariaplantation. This indicates that reforestation would only give a temporary soil quality enhancement.

AbstractWe assessed pre- and posteradication nitrogen and phosphorus dynamics in longleaf pine sandhill stands severely affected by cogongrass. Across a 7-yr posteradication (glyphosate + imazapyr) “recovery chronosequence,” which included untreated cogongrass, uninvaded reference, and treated plots, we analyzed soils for total N, potentially available P (Mehlich-1 [M1]), pH, and organic matter content. We also used resin bags to assess fluxes of plant available N and P in the soil solution. Additionally, we used litterbags to monitor the decomposition and nutrient mineralization patterns of dead rhizome and foliage tissue. Our results indicate similar total N and M1-P contents in both cogongrass-invaded and uninvaded reference plots, with levels of M1-P being lower than in cogongrass plots for 5 yr after eradication. Soil organic matter did not differ between treatments. Resin bag analyses suggest that cogongrass invasion did not affect soil nitrate availability, although a pulse of NO2+ NO3occurred in the first 3 yr after eradication. No such trends were observed for ammonium. Resin-adsorbed PO4was lowest 3 yr after eradication, and pH was highest 5 yr after eradication. Our litterbag study showed that approximately 55% of foliar biomass and 23% of rhizome tissue biomass remained 18 mo after herbicide treatment. Substantial N immobilization was observed in rhizomes for the first 12 mo, with slow mineralization occurring thereafter. Rapid P mineralization occurred, with 15.4 and 20.5% of initial P remaining after 18 mo in rhizomes and foliage, respectively. Overall, our findings indicate that cogongrass invasion has little to no effect on soil nutrient cycling processes, although some significant—but ephemeral—alterations develop after eradication.
