Izuchena vozmozhnost' primeneniya prirodnyh organicheskih meliorantov – lesnoy podstilki v doze 5, 10, 20 kg/m2 i lesnogo opada v doze 10kg/m2 pri vyraschivanii posadochnogo materiala sosny obyknovennoy v usloviyah srednesuglinistoy dernovo-podzolistoy pochvy. Effektivnost' primeneniya prirodnyh meliorantov ocenivalas' po biometricheskim pokazatelyam, masse nadzemnoy chasti i bazisnoy plotnosti drevesiny stvolika. Seyancy raspredelyalis' na 4-e gruppy standartnosti: 1. standartnye po diametru i; 2. standartnye po diametru i nestandartnye po vysote; 3. nestandartnye po diametru i standartnye po vysote; 4. nestandartnye po diametru i vysote. V variante primeneniya opada dolya standartnyh seyancev byla vyshe na 10 %, a variantah primeneniya podstilki na 20-30 % bol'she, chem v kontrole. Naibol'shiy vyhod standartnyh seyancev – do 60 % ot obschego kolichestva seyancev – nablyudalsya v variantah primeneniya podstilki v doze 10 i 20 kg/m2. Ne vyyavleno znachitel'nyh razlichiy po velichine diametra kornevoy sheyki u seyancev sosny sootvetstvuyuschih grupp v raznyh variantah opyta i po sravneniyu s kontrolem. Pochti vo vseh variantah opyta s primeneniem podstilki i opada vysota seyancev 1-4 grupp okazalas' dostoverno bol'she, chem v kontrole. Po masse hvoi, masse stvolika i obschey masse nadzemnoy chasti standartnye seyancy pochti vo vseh variantah opyta suschestvenno ne otlichalis' ot seyancev v kontrole. U seyancev 1-2-y grupp dostoverno naibol'shie pokazateli bazisnoy plotnosti drevesiny pobegov 1-go i 2-go goda vyraschivaniya byli otmecheny v variante opyta s vneseniem podstilki v doze 20 kg/m2. Ustanovleno, chto po sovokupnomu polozhitel'nomu effektu optimal'nym organicheskim meliorantom dlya pochvennyh usloviy provedeniya opyta mozhno schitat' lesnuyu podstilku s dozoy vneseniya 20 kg/m2.
