[Characteristics of Cadmium Concentration and Transport of in Farmland with Different Cadmium Pollution Degrees].

This study aimed to elucidate the cadmium (Cd) concentration and transport characteristics of in farmland with different Cd pollution degrees, so as to provide a reference basis for phytoremediation of Cd-contaminated farmland. The multi-point experiments in farmland with different Cd pollution degrees[(Cd) 0.32-38.

[Soil fertility characteristics and their influencing factors in tea plantations of Jiangxi Pro-vince, China].

To investigate soil fertility status and characteristics of typical tea plantations, we selec-ted 372 typical tea plantations of 21 areas across Jiangxi Province and analyzed the soil nutrient, spatial data, and their correlations with topography, soil type, elevation and plantation age. The results showed that soil pH, organic matter, alkaline nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus and total potassium of tea plantation in Jiangxi reached 53.9%, 60.
