The restricting elements include, first of all, the Iow precipitation sum especially at the time of intensive growth of plants, and too high share of soils with low bonitation classes poorly equipped with nutritive components and subject to overdrying. This accounts for a relatively big intensification of rye-and-potato crops giving on the average lower yields than the national average. This is best noticeable in southem regions of the zone. The northern part of the food zone has the most favourable index of agricultural effectiveness. That is due to, a suitable character of the land sculpture (mainly plains or small elevations) and soils of wheat complexes appearing here. Despite relatively low indexes, the natural conditions in the examined area do not reistrict develapment of crops production. At present they are utilized to an average degree. It is possible to expand largely the intensive crops cultivation area through better development of land reclamation and fertilization. The biggest reserves of growth of crops production exist in the northern and central parts of the food zone, and especially on soils of the very good rye complex and good wheat copliex. 1983-01-01T00:00:00Z http://hdl.handle.net/11089/7208 Zapotrzebowanie na żywność oraz bilans żywnościowy w strefie żywicielskiej woj. miejskiego łódzkiego Bernacka-Baranowa, Janina; Kołatek, Nina The article begins with a short description of nourishment norms and trends in real food consumption in Poland followed by definition of demand for food in the food zone of Łódź administrative province baing besed on nourishment norm D and average national consumption level. The performed food balance being a comparison between raw agricultural production and demand for food revealed that in the late seventies this zone was able to ensure the consumption of staple foodstuffs for the entire population inhabiting this area both at the level of nourishment norm D and at the average national level: to meet also oth er needs such as export, reproduction etc. Moreover, it accumulated surpluses of grain, meat, potatoes, and sugar beets. On the other hand, production of eggs and milk was insufficient within this zone. 1983-01-01T00:00:00Z http://hdl.handle.net/11089/7205 Produkcja roślinna Niepsuj, Andrzej A big urban centre, as an absorptive consumer market of foodstuffs, exerts an influence on the profile of the agricultural production in neighbouring areas through market mechanisms. The theoretically delimitated area of the food zone in the urban administrative province of Łódź occupies 2,381.3 thousand hectare, and encompasses eight administrative units (provinces). This area is characterized with a distinct predominance of the agricultural function, which is reflected, among others, in a high percentage share of arabie land in the overall area considerably exceeding the national average figures. The biggest part of areas under crop is utilized for grains (55 p.c.), includlng mainly rye, which is cultivated almost twice as much intensively than the national average. Production of grains predominates in the central part of Sieradz province and in the eastern part of Piotrków province. Among the remaining crops, potatoes, sugar beets, and field cultures are of the biggest consumer importance. Production of food of vegetable origin in this zone accounts for ca. 10 per cent of the overall national production. In particular kinds of crops this share amounts to: grain — 9.7 per cent, potatoes — 11.6 per cent, vegetables — 10.2 per cent, fruit — 8.2 per cent. The northern areas of the food zone boast the highest agricultural productivity and those belonging to Piotrków province — the lowest. On the basis of the available planning reports and prevailing trends of changes in the land-cultivation structure, the author performed a rough estimation of production size (Table 7), which revealed favourable prospects of full satisfaction of food demand in Łódź agglomeration in the field of products of vegetable origin. 1983-01-01T00:00:00Z http://hdl.handle.net/11089/7199 Zasoby paszowe i produkcja zwierzęca Rouba, Helena The article discusses the present sta e in the animal production within the food zone of th e urban administrative province of Łódź against the background of fodder supplies. There is also outlined the concept of development of these food economy spheres till 1990. The food zone in question, despite its insignificant fodder resources, is charaoterized with a big size of livestock and big marketability of the animal production. The spatial distribution of animal breeding and of market-oriented production is differentiated by natural and socio-economic factors. Intensification of the fodder base and its proper utilization will pave the way for rational development of the animal production, and thus for increased production of food in the food zone of Lódź administrative province. 1983-01-01T00:00:00Z
