Nutrient contents of two lettuce cultivars fertilized with organic compost

Nutrient contents of two lettuce cultivars fertilized with organic compost

With the purpose of evaluating the effect of organic fertilizers on the mineral nutrition of lettuce, two organic composts were used: One prepared by a traditional way, and another which went through by the actions of earthworms (vermicompost), and, three different methods of application (broadcast, per hill and in the row). The organic composts (with and without earthworms) did not increase the nutrient contemts in the leaf tissue, with the exception of K. The contents of P, Ca, Mg, and S, were not statistically different frorn the chemical treatment (control). A significant decrease in the nitrate content was observed with compost treated plants.

Com o objetivo de avaliar o efeito de compostos orgânicos sobre a nutrição mineral de alface (Lactuca sativa L.), foram utilizados dois compostos orgânicos: um, preparado de forma tradicional, e o outro, que passou pelas ações de minhocas, isto é, vermicomposto; e três formas de aplicação do composto (a lanço, na cova e na linha de plantio). Os compostos orgânicos não aumentaram os teores de nutrientes na parte aérea das plantas, exceção feita para o K, enquanto os teores de P, Ca, Mg e S permaneceram estatisticamente iguais à testemunha química, com significativa diminuição no teor de nitrato.
