About

Professor Jehangir Bhadha is a faculty member at the University of Florida's Everglades Research and Education Center, working within the Soil, Water, and Ecosystem Sciences Department. His research focuses on evaluating legacy phosphorus chemistry, bioavailability, and capture, utilizing advanced analytical techniques such as ICP-OES, NMR, and XANES. He is involved in understanding phosphorus dynamics in various soil types, including acidic, organic, and calcareous soils, with the aim of developing sustainable phosphorus management strategies to enhance crop productivity and minimize environmental impacts. His work also includes investigating nutrient dynamics in the organic muck soils of the Everglades Agricultural Area, addressing challenges related to phosphorus use efficiency and water quality improvement.

  The concept of phytoplankton functional groups was used to assess phytoplankton community structure in an attempt to better understand their spatial and seasonal variation in Lake Okeechobee, USA. Samples were collected for analyses during summer and winter. 23 phytoplankton functional groups were identified among 102 species, of which 9 groups (H1, M, C, MP, Y, S1, J, X1 and X2) were categorized as dominant. Y represented by Cryptomonas ovate and H1, represented by Anabaena circinalis and Anabaena variabilis, were dominant in some sites in summer corresponding to higher temperatures. In winter, the biomass of the functional groups was dominated by chlorophyta group X2 corresponding to lower temperatures, and relatively high nutrients. Redundancy analysis (RDA) with Monte Carlo test revealed that water temperature (WT), TP, and TN were the most dominant environmental variables which influenced phytoplankton functional group distribution in Lake Okeechobee. Functional group H1 was associated with TN, pH, TP and WT. Similarly, functional group Y was significantly positively correlated with TN, TP and WT but negatively correlated with TN/TP ratios. This study reveals the importance of physical–chemical variables across a spatial and seasonal gradient, in structuring phytoplankton functional groups, and consequently in the assessment of environmental status of the lake.

  The addition of agricultural by-products to mineral soils has the potential to improve crop production. This study aimed to determine the effects of the readily available sugarcane (Saccharum officinarum) milling by-product bagasse as a soil amendment on yields of sugarcane grown on a sandy Entisol of South Florida. The field trial was conducted on a commercial sugarcane farm for three annual crop cycles (plant cane and two ratoons). Four treatments including 5 cm bagasse (85 ton ha−1); 10 cm bagasse (170 ton ha−1); 10 cm bagasse (170 ton ha−1) plus 336 kg ha−1 ammonium nitrate; and a control (without bagasse and ammonium nitrate) were evaluated. Results indicate that one single application of bagasse increased sugarcane biomass and sugar yield by approximately 23% in the plant cane year. A higher application rate of bagasse (10 cm of bagasse) was recommended since it had a longer effect on increasing sugarcane biomass and sugar yield. Bagasse application enhanced silicon (Si) supply and increased Si plant nutrition. However, the effects of bagasse on the other leaf nutrients were not significant.

• Everglades Agricultural Area Soil Subsidence and Sustainability

  This 4-page major revision, a publication of the UF/IFAS Department of Soil and Water Sciences, highlights the current status of Histosols within the Everglades Agricultural Area in southern Florida. Over the last century, soils within the region have gradually been lost via oxidation, a process commonly referred to as soil subsidence. The rate of subsidence is gradually declining, due to factors such as increased mineral content in soil, humification, and water management (maintenance of higher water tables). Best Management Practices and crop rotation help slow down the rate of oxidation and promote soil sustainability within the region. Written by Jehangir H. Bhadha, Alan L. Wright, and George H. Snyder.https://edis.ifas.ufl.edu/ss523
