Poster presentation

Organic waste disposal has caused increasing environmental economic problems. Also, the high cost of synthetic fertilizers is a problem for farmers. The purpose of this investigation was to assess the influence of the low cost vermicompost technology (which uses the organic wastes) on the crop production. Outcomes: 1.Vermicompost is rich in macro and micronutrients, vitamins, growth hormones, enzymes and immobilized microflora. 2.Vermicompost can be produced "on-farm" at a low cost using simple techniques, whereas chemical fertilizers are high-tech and expensive products produced in factories. 3.Vermicompost improves germination, growth, biomass and yield in plants. 4.Vermicompost increased mineral nutrients, antioxidant activity and total phenolics in plants. 5.Vermicompost has been widely used for the management of plant diseases and pests.

The application of stabilized silicic acid is called the ‘silicic acid agro technology’ (SAAT) This technology has shown to be very effective on almost every crop: increase of root system, loner stem/tillers, increase of leaves resulting in more yield and higher quality. SAAT decreases as well biotic as abiotic stresses. Due to a (much) lower infection rate, the use of pesticides can be reduced with (at least) 50%. The product is safe (as well for the plant, the soil, the farmer as the consumer) and ecologically friendly. The purposes were to see if SAAT influences the growth of leaf celery and is there effect of SAAT so early in plant development. Conclusions: Silicic acid improved the quality of leaf celery transplants: leaf celery transplants were taller and stem diameter was greater in silicic acid treatment compared to control. The content of nitrates in raw leaf celery transplants was not statistically different between treatments. The content of Nitrogen, Calcium and Magnesium in leaf celery transplants dry matter were higher in silicic acid treatment compared to control treatment. The content of Phosphorus and Potassium in leaf celery transplants dry matter were not significantly different between treatments.
