Soil samples from twenty seven sites of Indian Sundarbans were analysed for some chemical parameters, These sites were divided into three inundation types namely, diurnal, usual springtide and summer springtide. The study demonstrated that most of the soil properties significantly varied with inundation type. Sites inundated by usual springtides exhibited lowest concentrations of pH, salinity (Sal), available phosphorus (I)), and exchangeable potassium (K), sodium (Na) and magnesium (Mg), whereas summer springtide inundated sites had the highest concentrations of Sal, organic carbon (OC), available nitrogen (N), Na, K and Mg. Highest level of P and lowest N in the diurnally inundated sites could be attributed to increased mobility of phosphates and denitrification or volatilization losses of inorganic nitrogen in the soils respectively, Highest concentration of in summer springtide inundated sites could be attributed to increased ammonium ion mobility in the soils.

Soil serves as a more reliable index for productivity than water qualities. The productivity of any pond depends largely on the quality of bottom soil that is “store house of nutrients.” The present paper deals with the study of physicochemical parameters like organic carbon, pH, Electrical conductivity, Nitrogen, Phosphorus, Potassium of soil from Muthannan Kulam,Coimbatore (March 2013- May 2013). Analysis for the above parameters indicated contamination of the soil quality due to some anthropogenic activities.

In 2019, 71 years after the establishment of a static fertiliser experiment, the chemical and biological properties of Luvisol soil with sandy-loam grain-size composition were determined. Soil samples were taken from six fertilised treatments: half-dose nitrogen, phosphorus and potassium in mineral fertilisers (½ NPK); full-dose nitrogen, phosphorus, potassium (NPK); manure fertilisation + nitrogen, phosphorus, potassium, magnesium and liming (FYM NPK Mg Ca); manure + mineral fertilisers without magnesium and liming (FYM NPK); manure + nitrogen and phosphorus (FYM NP); manure + nitrogen and potassium (FYM NK). The soil was tested in two layers at depths of 0–20 cm and 20–40 cm. Soil samples were tested for: pH in 1 M KCl (pH); electrical conductivity (EC); organic carbon content (OC); content of available phosphorus (Pa), potassium (Ka), magnesium (Mga) and sulphate sulphur (S-SO4); total number of bacteria (Bt), cellulolytic microorganisms (Bc), fungi (Ff) and actinomycetes (Ac); and alkaline phosphatase (AlP), acid phosphatase (AcP) and arylsulphatase (ArS) activity. The fertilisation that most favourably affected the chemical and biological properties of the soil was FYM NPK Mg Ca. This fertilisation increased: pH and EC; OC, Ka and Mga contents; Bt and Bc abundance; and AlP activity relative to all the methods of mineral and organic–mineral fertilisation that did not include all the ingredients of mineral fertilisers. On the other hand, the least favourable soil properties were formed by ½ NPK fertilisation in the 0–20 cm layer, and by the long-term use of mineral fertilisers only in the 20–40 cm layer.

Abstract Researches on the use of waste vegetable (tomatoes, peppers) and fruits (apples, plums) in order to improve the nutritional quality of the soil have been performed. The content in nitrogen, phosphorus, potassium, humus, organic matter have been analyzed in fruits and vegetable waste and also in soil before and after mixing with each waste at a ratio of 1:2.5. Analyses were done by using current analytical methods (chemical and absorption molecular spectrometry) after previous mineralization of samples with appropriate reagents. To investigate the effect of vegetable wastes on the plants growth, wheat has been planted in the witness soil sample and in the mixed soil with wastes. The nutrients concentration in vegetable waste was higher than in fruit waste (33-75%). Available phosphorus concentration increased about two times in soil with fruit waste while in the soil with vegetable the increase was of about 3 times. Potassium concentration increased about three times in soil mixed with both types of waste. Although potassium and organic matter have higher values in the soil amended with fruit waste than in the witness soil, the height of the wheat was similar with those in the control soil due to the limiting role of phosphorus.

Abstract Soil formation is a long term process and diverse soils are formed in different localities due to various soil forming factors over the landscape. Soil classification plays critical role in various aspects of agricultural engineering. Physico-chemical parameters play an important role in soil classification. In this paper, we present a comprehensive classification model for soil texture classification by using Linear Discriminant Analysis (LDA). We took the Physico-chemical properties of the soil, which include soil moisture, temperature, electrical conductivity, pH, organic carbon, available nitrogen, available phosphorus and potassium as independent variables, while the soil type was taken as the dependent variable. Feature selection is employed using Boruta algorithm. The performance of the proposed classification model is evaluated and expressed in terms of overall accuracy and kappa coefficient. Results show that the average prediction accuracy and kappa coefficient of the proposed model are 96.3% and 0.944 respectively, indicating that the model can be used effectively for soil classification for a set of suitable dependent variables.

Fusarium genus comprises important saprophytic and phytopathogenic fungi and is widespread in nature. The present study reports the occurrence of Fusarium spp. in soils from two mangrove forests in northern Peninsular Malaysia and analyzed physico-chemical properties of the mangrove soil. Based on TEF-1α sequences, nine Fusarium species were identified: Fusarium solani species complex (FSSC) (n = 77), Fusarium verticillioides (n = 20), Fusarium incarnatum (n = 10), Fusarium proliferatum (n = 7), Fusarium lateritium (n = 4), Fusarium oxysporum (n = 3), Fusarium rigidiuscula (n = 2), Fusarium chlamydosporum (n = 1), and Fusarium camptoceras (n = 1); FSSC isolates were the most prevalent. Phylogenetic analysis of the combined TEF-1α and ITS sequences revealed diverse phylogenetic affinities among the FSSC isolates and potentially new phylogenetic clades of FSSC. Soil analysis showed varied carbon content, pH, soil moisture, and salinity, but not nitrogen content, between sampling locations. Regardless of the physico-chemical properties, various Fusarium species were recovered from the mangrove soils. These were likely saprophytes; however, some were well-known plant pathogens and opportunistic human pathogens. Thus, mangrove soils might serve as inoculum sources for plant and human pathogenic Fusarium species. The present study demonstrates the occurrence of various Fusarium species in the extreme environment of mangrove soil, thereby contributing to the knowledge on species diversity in Fusarium.
