The role of green manure crops in Hungarian plant production

Abstract

According to the data of KSH (Hungarian Central Statistical Office), the sowing area of cereals in the crop year 2016 was over 2.56 million ha, on which winter wheat and maize were produced in a rate of around 50–50%. Regarding these data it is obvious that the domestic cropping structure has been simplified and become unilateral. This unfavourable crop rotation system causes several problems. The number of Hungarian livestock decreased in the past decades. The amount of manure was 24 million tons in 1960, but only hardly 4.5 million tons of organic manure was applied in 2016. Therefore, the importance of other possibilities, alternatives for organic matter recovery have become enhanced. This is especially important from the aspect of sustainable plant production. The fact that the European Union has introduced new directives for subsidiaries in 2015 has to be noted as well.
 The objective of the set experiment is to find new technological solutions that are suitable for the execution of sustainable plant production by inadequate crop rotation, organic substance recovery conditions or under more unfavourable climatic conditions.

Lagged Effects of Winter Catch Crops Followed by Sweet Corn on Onion

“…One of the priorities is enriching the soil with organic matter, which restores the soil fertility and increases its buffer properties. Across Europe, the production of fertilizers of animal origin is insufficient, and, therefore, increasing attention is paid again to the green manure of plant origin [Talgre et al, 2012;Fekete and Pepó, 2018;Thavarajah et al, 2019]. Green manure should become a permanent element of improving the soil fertility in the integrated and organic farming systems.…”
