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. Strength calculations were carried out with the use of computer system of the high range group.

This Regulation of the Minister of Environment, which is composed of 12 paragraphs and one Annex, lays down: (1) method of making available information on the environment, specified in art.30 of the Environment Protection Act; (2) minimal scope of information made available; (3) form of the information; (3) frequency of making information available.

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. This paper presents a case study of the lower Shiwalik hills, in Rupnagar, Punjab, India, to trace land-use and land-cover changes during the past 17 years, with an emphasis on groundwater quality and quantity.

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. Principles these be realized in special means by ecological agriculture as sustainable system of food production.
