Creation artificial soil-ground at gardening of objects of landscape architecture in Western Siberia

Abstract

Now for creation of a fertile layer usually use peat-sandy mixes in various parities, which initially do not approach for long-term development of grasses. It leads to that the grassy cover on slopes of roads, city lawns within 2-3 years perishes and is replaced natural by weeds with the vegetation which is not forming strong of sod. The carried out analysis of granulometric structure of soils on which perennial grasses grow, has shown, that as a part of artificial soil the clay containing oozy particles (<0.001 mm) should be an obligatory component. The developed optimising model has shown, that at observance of necessary conditions probably reception artificial soil of middle-loamy granulometric composition possessing optimum physical and agrochemical properties, necessary for long growth of perennial grassy vegetation. As local components it is necessary to use clay, small sand, peat in the parities received at calculation of optimising model. The parity between sand, peat and clay should make 1:2:7. For effect prevention acidification from peat and improvement of agrochemical properties it is necessary to add on 100 kg of a mix of 0.5 kg complex fertilize and 0.2 kg of a dolomitic flour that will provide nutrients to plants while in artificial soil it's own microflora will not start to work.
