1994
Kaniuczak, J. (University of Agriculture in Cracow, Rzeszow (Poland). Dept. of Chemization of Agricultural Production)
During the four-year long period of plant cultivation in crop rotation with differentiated mineral NPK fertilization against the backgroumd of the constant dose of farm manure, magnesium combined with liming, the decrease in the available magnesium content in all fertilization objects and the decrease in phosphorus and potassium contents in the objects without the NPK fertilization was found

Kaniuczak, J. (University of Agriculture in Cracow, Rzeszow (Poland). Dept. of Chemization of Agricultural Production)
In the experiment a differentiated mineral NPK fertilization was applied on the background of constant fertilization with farmyard manure in dose of 25 t/ha. Two experiments were carried out, in which also differentiated mineral fertilization against the background of constant fertilizing with magnesium and liming was applied. The experiment was carried out on acid soil and very acid one. The crop rotation in both the experiments was similar, the differences pertained only to the variety of fodder plant. In the result of 4-year long intensive cultivation of plants in crop rotation and differentiated mineral fertilization the soil reaction of very acid soil changed for acid while that of acid changed for worse

Kapusta, F. | Burak, I. (Akademia Rolnicza, Wroclaw (Poland). Inst. Ekonomiki i Organizacji Rolnictwa)
The aim of this work is to examine the influence of the following factors on the size of non-agricultural production in agricultural collective farms of Opole province in 1980-82, 1986-88. These factors are: the time of economic activity, resources of factors of production, level of agricultural commodity production and agricultural processing. 106 collective farms were examined.

Durch das Herbeifuehren agrar- und landschafts-oekologisch guenstiger Bedingungen koennen zwar nicht alle Umweltprobleme der modernen Landwirtschaft geloest werden, der grosse Konflikt zwischen Landwirtschaft und Naturschutz laesst sich aber verringern. Wenn die Entwicklung des Integrierten Landbaues noch durch die Honorierung spezifischer oekologischer Leistungen der Landwirtschaft ergaenzt wird, dann kann die Landwirtschaft mit diesem Massnahmenbuendel ihre Verpflichtungen zur Erhaltung der Kulturlandschaft als Lebensraum fuer Pflanzen, Tiere und Menschen besser denn je erfuellen.
