“…Contudo, os teores de N-NO 3 -na solução coletada aos 13DAA de composto foi maior no solo submetido à aplicação de 24L, comparativamente ao solo sem aplicação, o que pode decorrer da maior liberação de N-NO 3 -dos resíduos orgânicos. Apesar de a liberação de N-NO 3 -pelos resíduos ocorrer normalmente próximo aos 20DAA no solo (AITA & GIACOMINI, 2008), a baixa relação C/N (9,65) do composto Tabela 1 -Teor total de nutrientes nas folhas completas, massa, diâmetro de frutos, e produção, em pessegueiros submetidos à aplicação de composto.…”

RESUMO A aplicação de composto orgânico no solo pode incrementar a produção de pêssego, porém parte do N pode ser perdido por lixiviação e volatilização. O trabalho objetivou avaliar o estado nutricional das plantas, a produção de pêssego, a lixiviação de formas de N no solo e a volatilização de N-NH Palavras-chave: resíduo orgânico, N mineral, Prunus persica. ABSTRACT The application of organic compost to the soil can increase the production of peach, although part of the N may be lost by leaching and volatilization. The aim of this study was to evaluate the nutritional status, yield of peaches, leaching of N forms and volatilization of NH

“…The pH is the most influential parameter in this process; however, in the range of values observed in this experiment pH effect is reduced. AITA & GIACOMINI (2008) in an experiment with SW application in soil cultivated with maize noted that in the three years of the experiment, the amount of NO3 -increased rapidly in the soil surface layers. This rapid onset of NO3 -in the soil occurred because of high nitrification of ammonia nitrogen from manure, as evidenced by AITA et al (2007) in a field experiment.…”

Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The objective of this study was to evaluate the soil chemical properties and the leachate in face of the association of swine wastewater and mineral fertilization (MF) in oat cultivation. An experiment in drainage lysimeter was carried out, using SW applications associated to MF or not, where treatments consisted of doses of 0, 100, 200 and 300 m 3 ha -1 with the absence or presence of MF, under field conditions. We concluded that swine wastewater provided significant increases in sodium, copper, zinc, and nitrite + nitrate as well as pH and calcium reductions in the soil; and in the leachate, significant increase in sodium. Moreover, the use of mineral fertilizer comprising nitrogen, phosphorus and potassium induced a significant increase in phosphorus, potassium and electrical conductivity and a significant reduction in magnesium in the soil; however, in the leachate, electrical conductivity was increased.

“…The proper management of these wastes is essential to the sustainability of the Brazilian swine demonstrating the need to know the environmental aspects of the scrap (Menezes et al, 2003). The pig manure, consisting of a mixture of feces, urine, food scraps, and a variable amount of water are typically handled in liquid form (Aita and Giacomini, 2008).…”

The application of liquid swine manure (LSM) in the soil as biofertilizer is one of the most recycling alternatives adopted, because the nutrients contained in this residue can override, in part or totally, commercial fertilizers, crop productivity with a reduction in production costs. The goal with this work was to evaluate the use of LSM as a substitute of mineral fertilization on soybean culture in conditions of Savannah in 2014/2015. The experimental design was of randomized blocks with three replications. The treatments consisted of the use of mineral fertilizer recommended for soybean culture; without fertilization; and doses of LSM (25; 50; 75 and 100 m³ ha -1 ). The levels of N, P, K, Ca, Mg, Cu, Zn, Mn and Fe in leaves, seeds and dry matter from the shoot, plant height and productivity of grain was assessed. There was no statistical difference between treatments that received mineral fertilization (P and K) and the treatments that received pig manure, indicating that the use of pig waste as bio fertilizer on soybean fertilization may be a promising alternative. The mineral fertilizer in soybean culture can be replaced by shots of LSM from 80 m³ ha -1 with no losses in grain productivity in a clayey dystroferric Red Latosol. The applications of doses of pig manure generally did not promote increase in the content of nutrients in grains and in the extraction of nutrients by the aerial part of the soybeans plants.
