Pollution of soil environment with mineral fertilizers and ways of their migration deep into the soil
(Publishing House of Lviv Polytechnic National University, 2016) Gumnytskiy, Jaroslav; Lyuta, Oksana
One of the major problems of pollution of soil environment, namely by components of mineral fertilizers due to their massive and continuous use in agriculture was analysed in the article. Possible ways of penetration of not absorbed mineral fertilizers deep into the soil as the main reason for getting fertilizers in the lower layers of the soil environment were investigated. A comparison of the impact of soil and climatic conditions on the rate of penetration of fertilizers deep into the soil was done.
