The climatic, soil, ecological and economic features of the natural landscapes in the Krasnodar Krai were analyzed. The land structure of cultivated land in Western Ciscaucasia was given; the current state of soils in the Krasnodar Krai was analyzed. The changes in the content of humus in the arable layer over the century were considered. The qualitative state of agricultural lands, such as the susceptibility to erosion, the content of humus, and indicators of the nutrients balance in the soil was shown. A conclusion the existing zonal agriculture systems do not use the landscape diversity of the region was drawn. The need for switching to the adaptive landscape system of agriculture was substantiated. Using the GIS technologies, the boundaries of the natural landscapes in the Krasnodar Krai and the areas of agricultural land was determined by types and the degree of the manifestation of erosion processes. An eco-economic assessment of the field crop rotations adapted to the natural landscape by cultivated lands was made.

The irrigation area of Parsanga is located in Sumenep Regency, Madura Island of Indonesia. This irrigation area is 500 ha and the existing cropping pattern is paddy–paddy–second crop. There is water discharge deficiency due to the existing cropping pattern mainly in the dry season. Thus, this study intends to optimize the cropping pattern for 3 condition so that it can produce the maximum benefit of agricultural product. The first cropping pattern is paddy/second crop–second crop–paddy/second crop; the second proposition is paddy/second crop –paddy/second crop–second crop; and the third proposition is paddy–second crop–paddy/second crop. The optimization analysis is carried out by using the linear programming. The suggested three cropping patterns are not only able to solve the water deficiency; they can also present the more production benefit than the existing condition.

Nawadniany obszar Parsanga znajduje się w dystrykcie Sumenep na wyspie Madura w Indonezji. Ma powierzchnię 500 ha, a system upraw tam stosowanych to ryż–ryż–drugi plon. W warunkach takiego systemu uprawy występują deficyty wody, szczególnie w porze suchej. Z tego powodu przedstawione badania miały na celu optymalizację systemu upraw w trzech systemach, aby uzyskać maksymalne korzyści w produkcji rolniczej. Trzy systemy to: 1 – ryż/drugi plon–drugi plon–ryż/drugi plon, 2 – ryż/drugi plon–ryż/drugi plon–drugi plon i 3 – ryż–drugi plon–ryż/drugi plon. Optymalizację wykonano z zastosowaniem programowania linearnego. Sugerowane trzy systemy są w stanie nie tylko rozwiązać problem deficytu wody, ale także dają korzyści produkcyjne większe niż obecnie uzyskiwane.
