06.01.01.0224 Indices of Soil Fertility Standards for Cultivation of Agricultural Cultures (winter wheat, corn) on Irrigated Grey Meadow and Chestnut Mountain Soils: Final Report / Research In-te of Soil Science and Agrochemistry; Supervisor of studies J. A. Amirdjanian - 1995, 24p.

The standards of crop capacity on arable lands of the Republic have been processed. Studies have been made on crops of winter wheat and corn on irrigated grey meadow and chestnut mountain soils of Ararat valley by method of "microareas" with the purpose to clear up the showings of soils' cropping capacity for above-cited cultures on identical level of agrotechnics and fertilization, and on this basis to establish their optimum level and interrelation. These researches showed that under above-mentioned conditions the most decisive factors are moisture, humus and nutrient substances' contain and their reserves in arable layer of the soil. These soils are poor in active nitrogen, a little better- in phosphorus, and enough good in potassium. The interrelation between cropping capacity of above-cited cultures and reserves of active nitrogen and phosphorus has been established. These soils possess high ability to absorb phosphorus and potassium. In the last years was observed decrease of active nutrient substances in soil because of cutting down of fertilizers' utilization.
