In the presented paper there is presented description of discredited calculation model and course of calculations of design connected with project of secondary tillage set of new generation for simultaneous soil tillage and sowing with the use of universal drill. The design was elaborated with the use of computer system CAD-3D that allowed to build virtual solid models of machine.
This Regulation of the Minister of the Environment establishes: the list of substances particularly harmful to water environments and causing water pollution; rules on sewage testing; methods of analysis and procedure for verifying if the conditions are fulfilled; conditions which must fulfilled when inserting sewage into water or soil, including maximum permitted values of pollution and condit

The restructuring of the State Forests National Forest Holding activity also covered the functioning of the existing forest building infrastructure in the forest district administrations. In the paper I present the issues and specificity of forest building engineering, as well as problems connected with the sales of buildings offered by the State Forests National Forest Holding in 1999-2008.
Human activities have exerted small to large scale changes on the hydrological cycle. The current scenario regarding groundwater resources suggests that globally there is a water crisis in terms of quantity (availability) and quality. Therefore there is a great need for the assessment and monitoring of quality and quantity of groundwater resources at local level.
The aim of this study was to determine the effect of the soil tillage system on soil enzymatic activity. The performed investigations, employing two soil tillage systems: classical (ploughing) and simplified (no-tillage), were carried out on lessives soils (Luvisols) and rusty soils (Arenosols) differing typologically, with regard to their kind and species.
Agricultural production is based on environmental natural resources, that is soil, water, air and the whole landscape with its biodiversity. The using with resources of soil should therefore be balanced which would combine the tasks of farmhold utilizing from both economical, social and environmental protection point of views.
This Regulation of the Minister of Environment, which is composed of seven articles and five Annexes, lays down: (1) detailed conditions for the use of urban sewage sludge including the dosage of that sludge which can be used on land; (2) the scope, frequency and reference methods for testing urban sewage sludge and the land where that sludge is supposed to be applied.
The Act, which is composed of eight Chapters, lays down principles of protection of agricultural and forest lands, recultivation and improvement of land quality. Agricultural lands are protected by: limitation of their allocation for other purposes; prevention from degradation and devastation; recultivation; and preservation of peat areas and natural water reservoirs.
This Regulation of the Minister of Agriculture and Rural Development, which is composed of thirteen paragraphs and one Annex, establishes: requirements to be met by additives to enrich soil originated from animal by-products (soil improvers); veterinary requirements for neutralizing soil improvers; conditions for using soil improvers.
