Cumulative Effects of Nitrogen, Phosphorus, and Potassium Fertilizer Additions on Soil Respiration, pH, and Organic Matter Content

This paper used respective ratios of 50%, 60%, 70%, 80%, 90% and 100% of straw and pig excrement as raw materials to produce biogas and fertilizer. The test focused on gas production, the contents of available nutritional elements nitrogen, phosphorus and potassium, and the organic matter content. The experimental results demonstrate the fermentation can produce more biogas, nitrogen, phosphorus, potassium, and organic mass under the conditions which the fermentation cycle is 15 days and the ratio of straw and excrement is 70%.

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)

The content of nitrogen, phosphorus, potassium and organic matter in soil is an important index to determine soil nutrient status. In this paper, the contents of nitrogen, phosphorus, potassium, organic matter and soil salt in the soil of several different plant communities in the campus were measured by the chemical measurement characteristics of several different communities in University of Jinan. The differences in the measurement characteristics of soil chemical measurement in different plant communities were analyzed. The results showed that the highest organic matter content in several communities was Cherry Blossom community, 76.33mg/kg, and the highest ammonium nitrogen content was 196.08mg/kg; the highest content of available phosphorus was the community of Begonia, 168.14mg/kg, and the highest content of available potassium was the community of Robinia pseudoacacia, which was the highest salt content in 64.99mg/kg soil. The community of cherry blossoms is 569 μs. There was little difference in soil organic matter, available phosphorus and available potassium in different plant communities..

Soil chemical, biological and physical properties play important roles in soil quality and are related with increasing organic matter content, soil microbiological activity, plant nutrient content and availability. A new generation of soil amendments, containing specific soil microorganisms, are of great interest worldwide. Field experiments were carried out in 2018–2019 at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry. The aim was to determine the impact of bio-products containing Trichoderma reesei, Acinetobacter calcoaceticus or Bacillus megaterium, and their mixtures on changes of soil organic carbon (SOC), soil respiration, and microbial biodiversity in loamy Cambisol. Under dry meteorological conditions, Trichoderma reesei, Acinetobacter calcoaceticus and Bacillus megaterium bio-products resulted an increase in SOC content, C/N ratio, humic to fulvic acid ratio, soil respiration, and microbial biodiversity. It is concluded that the use of a mixture of three microorganisms (Trichoderma reesei + Acinetobacter calcoaceticus + Bacillus megaterium) is the most promising bio-amendment under climate change. Future research is needed on different soil types and textures.

Sawdust, straw, compost and manure were applied under dryland conditions to strawberry plantings at two locations. The effects on yield, leaf nutrient content, soil moisture, soil acidity and soil organic matter content were evaluated. Sawdust mulch and sawdust incorporation, the former being slightly better, produced highly significant increased yields over the check treatment and were superior to all other treatments. Soil moisture measurements showed that the sawdust treatments conserved soil moisture and this was regarded as the chief reason for the increased yields. The nitrogen, phosphorus, potassium, calcium and magnesium contents of leaves were affected somewhat by the treatments but the levels were considered adequate in all cases.Soil acidity was significantly increased in the sawdust plots but this was attributed to the additional nitrogen applied rather than to the sawdust per se. Sawdust incorporation, manure and compost treatments significantly increased soil organic matter content when compared to the check treatment.

The study of heavy metal speciation in bottom sediments of the Vyshnevolotsky water reservoir is presented in this paper. Sequential selective procedure was used to determine the heavy metal speciation in bottom sediments and thermodynamic calculation — to determine ones in interstitial water. It has been shown that Mn are mainly presented in exchangeable and carbonate forms; for Fe, Zn, Pb и Co the forms are related to iron and manganese hydroxides is played an important role; and Cu and Ni are mainly associated with organic matter. In interstitial waters the main forms of heavy metal speciation are free ions for Zn, Ni, Co and Cd, carbonate complexes for Pb, fulvate complexes for Cu. Effects of particle size and organic matter content in sediments on distribution of mobile and potentially mobile forms of toxic elements have been revealed.

Physical And Chemical

Soil, itself means Soul of Infinite Life. Soil is the naturally occurring unconsolidated or loose covering on the earth’s surface. Physical properties depend upon the amount, size, shape, arrangement, and mineral composition of soil particles. It also depends on the organic matter content and pore spaces. Chemical properties depend on the Inorganic and organic matter present in the soil. Soils are the essential components of the environment and foundation resources for nearly all types of land use, besides being the most important component of sustainable agriculture. Therefore, assessment of soil quality and its direction of change with time is an ideal and primary indicator of sustainable agricultural land management. Soil quality indicators refer to measurable soil attributes that influence the capacity of a soil to function, within the limits imposed by the ecosystem, to preserve biological productivity and environmental quality and promote plant, animal and human health. The present study is to assess these soil attributes such as physical and chemical properties season-wise.
