Studies Regarding the Effect of Organic Fertilizers on a Permanent Grassland in Petrova, Maramureş

Abstract

Grasslands have a great importance for humans around the world being the beginning of many of our food products. Since there is a direct connection between soil, plant and climate, scientists have become concerned of this interaction and studies have been conducted to describe this connection and to improve output in grasslands with the best possible measures. The experiment set up in Petrova, Maramureş in the autumn of 2012 was used to obtain information on how different types of manure influence vegetation and the output on permanent grasslands. Since there are other studies in this field, in different areas of Romania and in other countries, results can be compared so that a bigger picture can be obtained on how organic fertilizers influence the quality and quantity of forage.

Preliminary Study of the Effect of Chemical and Organic Fertilizers on a Semi-Natural Grassland in Vlăhiţa, Harghita Mountains, Romania

“…Application of manure (from cattle and horses) and/or mineral fertilizers increased the coverage of the Poaceae and Fabaceae family in the second and the third fertilization year (Rotar et al, 2016;Cirebea et al, 2020). Substantial increases in biomass yield in the following years after manure application were reported in many other grassland studies (Djukic et al, 2008;Štýbnarová, 2014;Botiș et al, 2015). Long-term studies (87-150 year) on the utilization of fertilizers demonstrated that chemical fertilizers reduce the soil pH, increase soil organic carbon stock mainly in the soil fractions with coarse particle-and fine particle size, and have a negative effect on diversity and abundance of plants from the Fabaceae family and other forbs.…”
