SUMMARY:

The search for organic inputs for agricultural activities produced in a sustainable way at more accessible costs for organic farmers has grown due to the demand for organic food in Brazil. With the increase in organic production, one of the biggest bottlenecks we face right from the start is the issue of nitrogen fertilization, among the various forms used, such as the use of green fertilizers that have a low Carbon/Nitrogen (C/N) ratio. and carry out Biological Nitrogen Fixation(BNF), as well as improving the supply of Organic Matter in the soil, another widely used way is the application of animal manure, in which with the Organic Legislation, these manures are now required to carry out composting of these products, mainly aiming to sterilize this material with the increase in temperature rise and reduction of the contamination load that these products can cause to the environment in general, but this becomes another problem for the farmer, since for a correctly carrying out composting, ends up depending heavily on labor and machinery due to the volume of material, as a study pelleted manure from laying birds will be used, which in addition to not depending on composting processes, would facilitate transport and storage of this product, in addition to demonstrating in initial research that this material has a very slow availability of this nutrient, which at first could be a problem, but a large window opens, since one of the objectives of organic agriculture is the use of poorly soluble nutrients and volatile. With the aim of participating in the process of knowledge formation, I will continue the work already carried out with Dehydrated Chicken Manure (EGD), with the main objective of evaluating its slow nitrogen release effect, since in short cycle crops such as in lettuce, it was observed that plants fertilized with EGD had lower absorption of Nitrogen by the soil, so we will carry out an experiment with doses of EGD fertilization in cabbage, since it is a plant with a long cycle and under conditions of climate in the region under study (Jacareí/SP, Vale do Paraíba) we were able to conduct farming throughout the year and this would give us a better idea of the effect of EGD on the soil and plants throughout the cycles.
