Absorption Capacity of Heavy Metals in the Case of Typha Latifolia Plant Species

Abstract

The main objective of the current research is to determine the absorption capacity of heavy metals (zinc and cadmium) in the case of Typha Latifolia plant species (root, stalk, leaf, flower). The plant samples was taken from the Bistrita river banks, respectively upstream of Bacau city, Romania, in Bogdan Voda area, and downstream of Bacau city). A very high absorption capacity of zinc and cadmium was recorded, in the case of Typha Latifolia plant species (especially in the stalk of the plant- 26.91�68.18 %, lower that in the root of Typha Latifolia plant species). A lower absorption capacity of zinc and cadmium was recorded, in the flower in the case of Typha Latifolia plant species (84.73�96.4 % lower that in the root of Typha Latifolia plant species).

Influence of Fertilizers on Soils Used for Oleaginous Crop

“…According to the data presented in the Code of good agricultural practices, 36.5 kg of nitrogen, 17.5 kg of phosphorus and 50 kg of potassium, active substances are required to produce a ton of oleaginous crop seeds and strains [3,4,24,[25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Utilization of Ozone and Composite Materials in the Seed Treatment to Stimulate the Germination and Growth of Agricultural Crops

“…Lately, an alternative in agriculture to stimulate the processes of agricultural development and harvesting of pure organic products is the use of physico-chemical methods. It has been established that ozone has unique antibacterial properties, ecological and safe for the environment, influences the microflora and increases the yield of plants [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Influence of Soil Fertilization Systems on Chemical Properties of the Soil

“…An important consequence is the accumulation in large quantities of the residual organic materials of solid, liquid and semi-liquid consistency. Normally these residues, with the value of organic fertilizers, are used to fertilize agricultural land [12,16,[28][29][30][31][32][33][34][35][36][37][38].The purpose of this research has been to determine the in2fluence of soil fertilizations systems on the chemical properties (magnesium, aluminium, potassium, calcium, iron and chlorine).…”
