relationships between soil parameters and physiological status of miscanthus x giganteus cultivated on soil contaminated with trace elements under npk fertilisation vs microbial inoculation
Environmental Pollution, 2017Co-Authors: Marta Pogrzeba, Szymon Rusinowski, Krzysztof Sitko, Jacek Krzyzak, Aleksandra Skalska, Eugeniusz Malkowski, Dorota Ciszek, Sebastian Werle, Jon P Mccalmont, Hazem M KalajiAbstract:Abstract Crop growth and development can be influenced by a range of parameters, soil health, cultivation and nutrient status all play a major role. Nutrient status of plants can be enhanced both through Chemical Fertiliser additions (e.g. N, P, K supplementation) or microbial fixation and mobilisation of naturally occurring nutrients. With current EU priorities discouraging the production of biomass on high quality soils there is a need to investigate the potential of more marginal soils to produce these feedstocks and the impacts of soil amendments on crop yields within them. This study investigated the potential for Miscanthus x giganteus to be grown in trace element (TE)-contaminated soils, ideally offering a mechanism to (phyto)manage these contaminated lands. Comprehensive surveys are needed to understand plant-soil interactions under these conditions. Here we studied the impacts of two Fertiliser treatments on soil physico-Chemical properties under Miscanthus x giganteus cultivated on Pb, Cd and Zn contaminated arable land. Results covered a range of parameters, including soil rhizosphere activity, arbuscular mycorrhization (AM), as well as plant physiological parameters associated with photosynthesis, TE leaf concentrations and growth performance. Fertilization increased growth and gas exchange capacity, enhanced rhizosphere microbial activity and increased Zn, Mg and N leaf concentration. Fertilization reduced root colonisation by AMF and caused higher chlorophyll concentration in plant leaves. Microbial inoculation seems to be a promising alternative for Chemical fertilizers, especially due to an insignificant influence on the mobility of toxic trace elements (particularly Cd and Zn).

Plant Growth Promoting Rhizobacteria Enhance the Efficiency of the Combination of Organic and Chemical Fertilisers in Sugarcane
Open Journal of Ecology, 2020Co-Authors: Chanyarat Paungfoo-lonhienne, Nantida Watanarojanaporn, Ratchaniwan JaemsaengAbstract:Modern agricultural practices involve the extensive use of Chemical Fertilisers to increase productivity. However less than half of the applied Chemical Fertiliser nitrogen is used by the target crops, and much of the remaining pollutes air and waterways. Farming systems that sustain productivity while reducing the negative effect on the environment are crucially needed. One avenue is to use plant growth promoting rhizobacteria (PGPR) as bio-Fertiliser to reduce the dependency on Chemical Fertiliser. The potential of PGPR to improve the efficiency of the combination of organic and Chemical Fertilisers has recently been proposed. Here, we demonstrate that this combination benefits sugarcane grown in field conditions.

CANFERT 1.0: A Chemical Fertiliser RlECOMMENDATION SOFTWARE FOR SUGARCANE PRODUCTION IN THAILAND
2020Co-Authors: S. KongtonAbstract:Chemical Fertiliser accounts for a substantial past of sugarcane production costs in Thailand, where most cane growers lack basic lmowledge regarding the use of festilisers. A computer program, CaneFest 1.0, is being developed to accurately determine recommendations for the application of N, P and K using the properties of the soils under sugarcane production throughout Thailand. The project includes: sugarcane soil identification using soil series maps; field surveys to confirm the identification; determination of nutrient requirements; cane growth simulation using CANEGRO 3.5 to determine the effect of water and nitrogen; econolnic analyses of Chemical festiliser recommendations and validation trials to confirm the recommendations generated by CaneFert 1.0. The resulting software allows users to identify the site by pointing an asrow on a map displayed on the computer screen. The farin's location, soil series, soil Chemical properties, N-P-K requirements, and the amount and method of Chemical Fertiliser application are also generated. It is anticipated that sugar mills, sugarcane grower associations, government agencies, agronoinists, and extension worl

The response of properties of soil cropped with shell beans and treated with disinfectant and Fertiliser during the plant growing season
Biology and Fertility of Soils, 2013Co-Authors: Pantelitsa Kapagianni, Nikos Monokrousos, George P. Stamou, Efimia PapatheodorouAbstract:Disinfectants and Fertilisers exert strong impact on soil processes by affecting the structure and the activity of the soil microbial community. Most relevant studies examined these impacts independently, under laboratory conditions and without crop cover. In this study, we have monitored the response of soil Chemical, microbial, and bioChemical properties to disinfectant and Fertiliser treatments in field plots cultivated with beans. The measured properties comprised microbial C and N, asparaginase, gultaminase, urease, and acid phosphomonoesterase activities and contents of organic N, organic C, inorganic N, and inorganic P. We ran four different treatments using different combinations of Chemical (metham sodium) and biological disinfectant (a mixture of neem cake and essential oils) and Fertilisers (NPK 8-16-24 and cow manure) in plots cultivated with shell beans, while the control soil was neither treated nor cropped with beans. The data were expressed as percentage (%RC) in relation to the control values. The disinfectant and Fertiliser treatments had less impact on soil properties compared to bean crop growth (except for microbial C and N, and content of organic C). In comparison to the control, higher activities of urease and asparaginase and content of inorganic N were recorded in bean cropped plots at the stage of seedlings (June), while higher activities of acid phosphomonoesterase and glutaminase and content of organic N were recorded at the stage of plant flowering (August). In October, the values of all properties were higher in the control plots compared to the treated plots. The joint effect of disinfectants x Fertilisers affected the response of content of organic C and N and extractable P and glutaminase activity. The %RC of the properties exhibited more negative values in plots treated with Chemical disinfectant and Chemical Fertiliser than in the other treatments. We suggested that the response of soil properties to disinfectants and Fertilisers were influenced by the growth of P. vulgaris .
