Conteúdo:

The use of dejections aiming the nutrients cycling, the adoption of the direct
plantation system (SPD) and the cultures rotation can be considered essential
practices to the sustainability of agricultural production. The use of swine dejections
in correct doses and handling is an alternative in agricultural properties, allowing the
development of integrated systems of production, with lower cost and risk of
damages to the environment. This study aimed to evaluate the chemical alterations
of K, Ca and Mg of a typical Yellow Red Rhodic in the city of Braço do Norte, Santa
Catarina state, due to the fertilization with liquid swine manure or chemical
fertilization, in the depths of zero to 15 cm, 15 to 30 cm, 30 to 45 cm and 45 to 60
cm. The recommended N and the double of the dose were supplied to the cultures.
There was a difference in the proportions of K, Ca and Mg of the ground during the
culture of the maize. Both the proportions of K and Ca and Mg were higher in the
superficial layer of the ground, diminishing according to the depth. In general, the
overlapping litter 2x treatment presented the highest values for the nutrients.
