ABSTRACT
An important area of the surface of Maramures county is said to be historically polluted, mainly due to the mining activities carried out for decades in this part of the country. The negative effects on the ecosystems from the adjacent areas fully justify the current ecological activities. Subsequent monitoring of the main environmental factors – soil, water, air – ensure the functioning of already made investments. An investment of several million dollars was made in the western area of the Baia Mare town (Baia Mare mining basin was one of the most important from Romania), in the residential neighbourhood Meda; the cleaning activities being completed in 2004. Field observations emphasized the necessity to study nutritive elements and microelements the ‘fresh’ soil offers today to the vegetal layer after 10 years from the completion of the cleaning activities; all these under the conditions that the surface is heavily influenced by the atmospheric and anthropological factors. This paper emphasizes that the prevalently mildly acidic reaction of the soil, the extremely low values of total nitrogen -nutritive element- and humus content indicate the necessity to carry out some improvement for organic rebalancing.

Keywords: greening, macronutrient, micronutrient, rehabilitation, tailing
