Changes In Soil Properties

This study was undertaken to investigate the changes in status of soil properties in four AEZs (AEZ 28, AEZ 9, AEZ 8 and AEZ 7) of Tangail district in Bangladesh over the span of the years. In 2017, the pH value of four AEZ was ranged from strongly acidic to slightly acidic but before 2000 it was strongly acidic to slightly alkaline. The present OM status was medium and before 2000 it was also medium. The present N status was very low, low, low and low, respectively but before 2000 it was low, medium, low and low, respectively. The present P status was low, low, low and very low, respectively in upland and low in wetland but before 2000 it was medium, medium, low and medium in upland and optimum, medium, medium and optimum in wetland, respectively. The present K status was medium, low, low and low in upland and medium, low, low and low in wetland, respectively but before 2000 it was optimum, high, high and optimum in upland and high, very high, very high and optimum in wet land, respectively. Under upland and wetland, the present S status was low, low, very low and low, respectively but before 2000 it was medium in all AEZ. The present Ca status was medium, medium, optimum and optimum, respectively but before 2000 it was optimum, high, high and high, respectively. The present Mg status was high, high, very high and very high, respectively but before 2000 it was medium in all AEZ. The Present Zn status was optimum, medium, low and low,  respectively but before 2000 it was  medium very high, very high, very high and optimum, respectively. The present B status was low in all AEZ but before 2000 it was optimum, optimum, low and low, respectively. With few exceptions, the nutrient status of the study area was reducing day by day and it was less than optimum level which was not suitable for sustainable crop production.

Abstract Aims Gypsum soils are P-limited atypical soils that harbour a rich endemic flora. These singular soils are usually found in drylands, where plant activity and soil nutrient availability are seasonal. No previous studies have analysed the seasonality of P nutrition and its interaction with the arbuscular mycorrhiza fungi (AMF) colonisation in gypsum plants. Our aim was to evaluate the seasonal changes in plant nutrient status, AMF colonisation and rhizospheric soil nutrient availability in gypsum specialist and generalist species. Methods We evaluated seasonal variation in the proportion of root length colonised by AMF structures (hyphae, vesicules and arbuscules), plant nutrient status (leaf C, N and P and fine root C and N) and rhizospheric soil content (P, organic matter, nitrate and ammonium) of three gypsum specialists and two generalists throughout a year. Results All species showed arbuscules within roots, including species of Caryophyllaceae and Brassicaceae. Root colonisation by arbuscules (AC) was higher in spring than in other seasons, when plants showed high leaf P-requirements. Higher AC was decoupled from inorganic N and P availability in rhizospheric soil, and foliar nutrient content. Generalists showed higher AC than specialists, but only in spring. Conclusions Seasonality was found in AMF colonisation, rhizospheric soil content and plant nutrient status. The mutualism between plants and AMF was highest in spring, when P-requirements are higher for plants, especially in generalists. However, AMF decoupled from plant demands in autumn, when nutrient availability increases in rhizospheric soil.
