Przyrodnicze podstawy rozwoju produkcji rolniczej na obszarze województwa skierniewickiego
Natural conditions in Skierniewice province are rather unfavorable for highly effective agricultural production. The 11- agitating factors include low precipitation amounts (table 2), and especially in the period of intensive plant growth along with a big share of soils belonging to low bonitation classes 'over 60 per cent), which are poor in nutritious components by their nature and suffer periodically or permanently from lack of humidity. It is most noticeable in central and central-south em regions of the administrative province where crops are below the national average. Simultaneously the province is poor in surface waters with agricultural storage reservoirs being absent. An important factor impeding modernization and intensification of plant production, and especially in animal breeding, is insufficient supply of rural farms with water. In the spatial structure of the province the index of quality agricultural production space is largely differentiated fig. 2 . Areas situated in Kutno Plain and in the eastern part of the Lowioz-Btonie Lowland are most favorable for agriculture. Considerable fodder reserves are to be found in today quite neglected green lands in the valley of the Bzura and its tributaries, which are ameliorated in only 18 per cent. The areas adjoining the Rawka river valley, and especially In its upper run are less useful for agriculture. Prevailing poor, usually rye-and potato soils reveal a low level of the agro-culture.
