Summary
Viie katseaasta (2012–2016) keskmised tulemused näitavad, et võrreldes tavasüsteemidega on maheviljelussüsteemidel eelised kestlikuks taimekasvatuseks. Viljelussüsteemi mitmekesistamine vahekultuuride ja lisaks veel kompostitud veisesõnnikuga, võimaldab oluliselt parandada mulla omadusi. Tõusis mulla mikroobide aktiivsus, mulla orgaanilise süsiniku ja üldlämmastiku sisaldus. Mulla mikroobide aktiivsuse ja üldlämmastiku sisalduse vahelised seosed aga vajavad jätkuvaid uuringuid.
Summary translation
Five-year study of potato cultivation in two conventional and three organic systems has shown that organic systems enhanced the soil microbial hydrolytic activity and increased the content of organic carbon. Significant increase in organic systems was reached by using winter cover crops in combination with composted cattle manure. Content of total nitrogen was not correlated with soil microbial activity and was not dependent on the cropping system. In conventional systems the lower soil microbial activity is explained by the pesticide influence.
