STUDY ON THE MANAGEMENT OF ORGANIC NUTRIENTS AT THE FARM LEVEL IN THE DEVELOPMENT MACRO REGIONS 3 AND 4 IN ROMANIA

Abstract

In the context of modern agriculture practiced in the conditions of favorable soil evolution, of increasing fertility in the conditions of maintaining a real ecological balance, organic fertilization by introducing humiferous resources into the soil has and maintains a well-defined place in increasing yields quantitative and qualitative per surface unit. No other simple or compound mineral fertilizer can replace the specific but also complex effects of organic fertilizers on soils and also on the evolution of crops.
Organic fertilizers have a multitude of effects and advantages, but mainly they have an essential supply of organic substances for the process of synthesizing humus from the soil, for stabilizing or increasing the reserve of this important soil component and for the dynamic balancing of the two predominant global processes in the evolution of soil organic matter – humification and mineralization.
The data presented in this paper are based on a study carried out within development macro regions 3 and 4 aimed at collecting information from farmers who use organic fertilizers on their farms. From total number of respondents, 54.5% mentioned the use of this practice currently, and 33.3% only used manure in the last year on an area varying between 25% and 50% of the cultivated area of the farm. The research also revealed that more than 83% of the respondents indicated that the organic fertilizer came from their own farms, which greatly reduces the costs of the agricultural activity and contributes significantly to the increase of the total profit from the farm.
