Fontes e doses de nitrogênio e alterações nos atributos químicos de um latossolo cultivado com capim-mombaça

Abstract: RESUMOO fornecimento de N tem sido importante meio para aumento da produtividade das gramíneas forrageiras tropicais no Brasil, pois, na maioria das áreas cultivadas, os teores desse nutriente no solo não atendem satisfatoriamente a necessidade das culturas. Avaliou-se o efeito da aplicação de diferentes fontes e doses de N sobre os atributos químicos de um Latossolo Amarelo e a produção do Panicum maximum cv. Mombaça. O experimento foi desenvolvido no Instituto Federal do Espírito Santo, campus Santa Teresa. … Show more

“…The amount of soil collected at each sampling point is an important step in soil fertility assessment procedures (ROSOLEM et al, 2010). For these authors, some tools may be unsuitable for sampling due to the small amount of soil collected or, to circumvent this problem, it may be necessary to increase the number of simple samples to form the composite sample.…”

“…Nitrogen fertilization among the nutrients used to replenish the fertility of pasture soils has been an important practice to increase the production of forage, especially in intensively managed areas, because nitrogen is the nutrient most extracted by forages (Rosado et al, 2014;Freitas et al, 2011).…”

“…Among nitrogen fertilizers, urea and ammonium sulphate are the most commercialized and applied to pastures in Brazil, with urea being the most used source, due to the lower cost per kg of nitrogen, however, when applied on the surface, N losses volatilization are high, limiting the fertilizer effect (Rosado et al, 2014). In turn, ammonium sulphate has lower losses of N when applied to acidic soils, in addition to providing sulfur for forages (Teixeira Filho et al, 2010).…”
