Alleviation of nickel toxicity and an improvement in zinc bioavailability in sunflower seed with chitosan and biochar application in pH adjusted nickel contaminated soil

Archives of Agronomy and Soil Science, Journal Year: 2017, Volume and Issue: 64(8), P. 1053 - 1067

Published: Dec. 1, 2017

This study demonstrates the reduction of nickel (Ni) toxicity and enhancing zinc (Zn) bioavailability from sunflower seed with biochar (BC) chitosan (CH) application to Ni contaminated soil. The pH experiment soil was adjusted value 6.5 prior its use in a greenhouse experiment. Acidified amended Zn (4 mg kg−1 soil), while BC CH, both as alone [1% each (w/w)] combination [0.5% (w/w)], were used immobilizing agents for Ni. Significantly higher concentrations found receiving ZnSO4 treatments. However, these results more pronounced treatment (Zn+CH+BC) where Zn, together applied. Zn+CH+BC improved quality parameters, phytate/minerals molar ratios, increased weight (per pot) up 75%, Fe 41%, 42% seed, reduced concentration 17% over control. Similarly, significantly decreased oxidative stress by improving antioxidant defense system sunflower. this preliminary suggest that further studies are obligatory corroborate extent immobilization under field conditions realistic applicable rates CH.

Soils in intensively farmed areas of the world are prone to degradation. Amendment such soils with organic waste materials attempts restore soil quality. Organic amendments heterogeneous media, which a source matter (SOM) and maintain or chemical, physical, biological ecological functionality. More specifically, an increase SOM can influence microclimate, microbial community structure, biomass turnover mineralisation nutrients.

Soil texture is an important factor determining how microplastics affect soil hydraulic characteristics

Environment International, Journal Year: 2022, Volume and Issue: 165, P. 107293 - 107293

Published: May 18, 2022

Microplastic pollution and changes to soil hydraulic characteristics affect the physical properties functions of soil; however, knowledge remains limited on how microplastics influence properties. Nonetheless, it is important understand these relationships maintain health ensure sustainable land use, especially in current "plastic age." This case study explored different particle sizes (20, 200, 500 μm) concentrations (up 6%) polypropylene three textures (loam, clay, sand). The results show that addition microplastic reduced saturated conductivity (Ks) soils by 69.79%, 77.11%, 95.79%, respectively. These observed adverse effects infiltration studied were influenced size, with larger particles having weakest effect. Furthermore, water retention capacity clay a greater extent than loam sand. In slope characteristic curve (SWRC) increased significantly, whereas content (θs) residual (θr) curves decreased significantly. Importantly, interaction between alters pore-size distribution reduces pore availability. Overall, this demonstrates impact textures, which can inform management strategies minimize accumulation yields where plastics are used agricultural production.
