Water erosion and soil water infiltration in different stages of corn development and tillage systems AGRIAMBI
Carvalho,Daniel F. de; Eduardo,Eliete N.; Almeida,Wilk S. de; Santos,Lucas A. F.; Alves Sobrinho,Teodorico.
ABSTRACTThis study evaluated soil and water losses, soil water infiltration and infiltration rate models in soil tillage systems and corn (Zea mays, L.) development stages under simulated rainfall. The treatments were: cultivation along contour lines, cultivation down the slope and exposed soil. Soil losses and infiltration in each treatment were quantified for rains applied using a portable simulator, at 0, 30, 60 and 75 days after planting. Infiltration rates were estimated using the models of Kostiakov-Lewis, Horton and Philip. Based on the obtained results, the combination of effects between soil tillage system and corn development stages reduces soil and water losses. The contour tillage system promoted improvements in soil physical properties,...

Chiseling and gypsum application affecting soil physical attributes, root growth and soybean yield Rev. Ciênc. Agron.
Santos,Esmael Lopes dos; Debiasi,Henrique; Franchini,Julio Cezar; Vieira,Marcos José; Balbinot Junior,Alvadi Antonio.
ABSTRACT This study aimed to evaluate the effect of chiseling and gypsum application on soil physical properties, soybean root growth and grain yield. An experiment was carried out in Londrina, Paraná state, Brazil, under a randomized complete block design, with six replications. The soil in the experimental area is classified as a dystroferric Red Latosol (Oxisol), containing 720 g kg-1 of clay. The experiment comprised four treatments: (1) continuous no-tillage (CNT) system without gypsum application, (2) CNT with gypsum application at 3.5 Mg ha-1, (3) chiseled soil without gypsum, and (4) chiseled soil with gypsum application. Regardless of gypsum application, chiseling increased water infiltration rate in soil and reduced penetration resistance. Gypsum...
