Privedeny rezul'taty issledovaniy mikroelementnogo sostava pochv, konkreciy i rasteniy agroekosistem Pri- morskogo kraya. Vyyavlena obschaya nesbalansirovannost' mikroelementnogo sostava pahotnyh gorizontov i ustoychi- vyy deficit Mo, Ni i Zn v agrotemnogumusovyh podbelah, intensivno ispol'zuyuschihsya v sel'skohozyaystvennom proizvodstve regiona. Soderzhanie Su i Co v issledovannyh pochvah povysheno po sravneniyu s regional'noy klarkovoy koncentraciey. Issledovannye pochvy harakterizuyutsya aktivnym formirovaniem pochvennyh konkreciy. Na osno- vanii izucheniya processa nakopleniya mikroelementov konkreciyami ustanovleno, chto konkrecii yavlyayutsya svoeo- braznymi deponentami pochvennoy sistemy i okazyvayut suschestvennoe vliyanie na pereraspredelenie mikroele- mentov v pahotnom gorizonte pochv. Vnesenie udobreniy soprovozhdaetsya dopolnitel'nym postupleniem valovyh i vodorastvorimyh form mikroelementov v pochvy i v konkrecii. Specifika soderzhaniya bol'shinstva issledo- vannyh mikroelementov v rasteniyah pshenicy obuslovlena uchastiem elementov v klyuchevyh metabolicheskih pro- cessah. Rezul'tatom vneseniya udobreniy yavlyaetsya uvelichenie soderzhaniya v rastitel'nyh tkanyah Pb i Cd. Odnako osnovnoy ob'em Pb i Cd, soderzhaschihsya v rasteniyah, vozvraschaetsya v pochvu v vide pozhnivnyh ostatkov. Takzhe v po- chvah udobryaemyh delyanok otmecheno uvelichenie kolichestva konkreciy. Analiz vzaimosvyazi mezhdu soderzhaniem razlichnyh form mikroelementov v pochvah, konkreciyah i rasteniyah pozvolili ustanovit', chto funkcionirovanie konkreciy yavlyaetsya odnim iz faktorov, ogranichivayuschih postuplenie nekotoryh mikroelementov v rasteniya i, vozmozhno, tem samym vliyaet na ih urozhaynost'. Uchityvaya tot fakt, chto dobit'sya uvelicheniya urozhaynosti nevoz- mozhno bez primeneniya udobreniy i sootvetstvenno soputstvuyuschih im primesey, v pochvah, ispol'zuemyh dlya pro- izvodstva sel'skohozyaystvennoy produkcii, konkrecii igrayut rol' balansiruyuschego komponenta agroekosistem, kotoryy reguliruet pitanie rasteniy ekologicheski bezopasnym putem.
