Abstract

While the nutrient supply in conventional farming is mainly provided by fertilizers, the organic farmers have to use nutrient-rich organic materials to produce seedlings of high quality. The advantage of transplants use in the vegetable growing can be to realize earliness (it gives higher benefit), increase growth safety, etc. Effect of bacteria (like microbial agent) can transform faster the nutrients from organic material. It can give opportunity for organic manure to affect faster in the substrate. The aim of this research was to determine: growing lettuce seedling only with the use of organic materials, estimating the effectiveness of some microbial products in vegetable transplant growing, and effect of microbial products on efficiency of manures. The results show that the combination of organic fertilizers and soil bacteria has effect on the increasing of nitrogen up-take of plants.
