Influence of Mineral Fertilization and Zeolite on Soybean Productivity Elements in Climatic Conditionsfrom ARDS Turda.

Soybean is one of the most important oilseed crop production and forage feed, representing 58% of total production of oilseeds in the world and 69% of protein intake from forage. The experience aims assessing the effect of single and combined fertilization with different doses of chemical fertilizers and zeolite, the elements of productivity and microbiological characteristics of soil on nodule number of soybean crop in the climatic conditions from 2013 year. Following the results it is found that fertilization based on equal amounts of urea and zeolite affects positively nitrogen fixing symbiosis. The effect is being stronger than if the fertilization is made by urea, fertilizer complex and zeolite, the recorded differences are large. Soybean production in 2013 specified the largest production increase 1.74 t/ha produced by the variant treated with 50 t/ha urea + 50 t/ha zeolite with no significant differences.
