Megjegyzések:The aim of the modern agriculture is the sustainable development. It helps to keep the good environment for the next generations. One of the most important expectations regarding sustainable agriculture is the minimization of the use of industrial chemicals. By using by-products, we are able to decrease amounts of chemical fertilizers. One of these by-products is the digestate, also as known as digestate of biogas factory. This fluid contains several essential elements, for example N, K, S, Ca and Mg etc. and we can use it for nutrient supply in the crop production. The goal of the experiment was that we examined the effect of the fluid by-product of some macro elements (Ca, Mg, P, S and K) deficient maize plants. The fluid by-products were originated from a biogas factory located in Biharnagybajom. Maize (Zea mays L. cv. DKC 5170) seedlings were used in the experiments. We made hydroponics experiment in growth chamber, where the circumstances were controlled. We added 50 ml dm-3 digestate to the nutrient solution. At the end of the experiment (on the 21th day) the quantity of photosynthetic pigments (chlorophyl-a, chlorophyl-b and carotenoids) and the dry weight of shoots and roots were measured in the plants that were grown on nutrient solution. When we added the digestate to the nutrient deficiency nutrient solution, a more favorable effect was achieved on the measured parameters. Due to these results, we suggest the usage of the digestate of biogas factory in agriculture.

Cím:Use of industrial by-products and bio-effectors in crop produaction / Brigitta Tóth, Gerda Hankovszky, Zoltán Balla, Günter Neumann
Dátum:2016

Megjegyzések:The utilization of bio-effects (BEs), including various plant growth promoting microorganisms has been addressed to the sustainable agriculture.In this study, a combination of a bacterial BE (Proradix WG) based on Pseudomonas sp (DMSZ 1314) with root growth promoting and pathogen suppressive properties and a Laminaria seaweed extract (NEMATEC) were tested to investigate the nutrient acquisition of maize (cv Colisee) from sewage sludge and sewage sludge compost as recycling products from poppy shell-based alkaloid production on a low P organic farming soil (clay loam pH 6.8, 20 mg CAL-P/kg soil). The experiment was conducted in pots (3 kg soil) under controlled growth chamber conditions with phosphate (P) as major limiting nutrient.All organic fertiliser amendments had a positive effect on plant growth but did not reach the values of a full mineral P fertilisation. In the sewage sludge compost treatment, plant biomass production and particularly root length were increased by inoculation with Proradix while no effects were detectable in the sewage sludge treatment. No further improvements could be observed by additional inoculation with the seaweed extract NEMATEC. The results suggest that a proper selection of organic fertilisers with compatible BEs is a pre-requisite for successful strategies to improve utilisation efficiency of organic recycling fertilisers.
