Resumo: | This work aimed to assess physical and chemical attributes (texture, porosity, mean particle density, dry bulk density, flocculation degree, aggregation, hydraulic conductivity and penetration resistance, pH-CaCl2, calcium, magnesium, potassium, phosphorus and base saturation) along the transections of two cerrado (savannah) soils. Additionally, efficiency of the forestry remnants on the retention of sediments originated from agricultural activities was observed. The following soils were studied: 1. One site Typic Haplustox Latossolo Vermelho Distrófico (Panamá, Goiás, Brazil), cropped under conventional tillage system; 2. Two sites Typic Haplustept Cambissolo Háplico Eutrófico (Goiatuba and Jandaia, Goiás, Brazil), cropped under no-tillage system and Brachiaria pasture. Riparian forests at downstream of all cropped areas were found. Morphologic description of soil profiles and penetration resistance tests were performed. Deformed and undeformed soil samples at depths of 0-5, 5-10 and 10-20 cm for chemical and physical analyses were collected. For comparison of means Tukey-test at 5% probability was used. Management systems caused the following changes on physical and chemical attributes in comparison to riparian forests: a) Lower penetration resistance under no-tillage system on the Typic Haplustox soil, and a higher one on the Typic Haplustept soils; b) decrease of soil aggregation both under conventional and no-tillage systems, and increase under pasture; c) decrease of soil organic matter and calcium under all cropping systems. Soil morphological descriptions on the riparian forests showed layers of non pedogeneticized materials over the A horizons, likely originated from the upstream areas, from where terraces have been withdrawn. Riparian forests downstream the cropped areas under no-tillage and pasture systems, due to the unsuitable width and anthropic actions, were not able to retain satisfactorily the ran off sediments; under conventional tillage, however, this width was considered to be suitable in conformity to Brazilian environmental laws |

Adicionalmente, avaliou-se a eficiência dos remanescentes florestais na retenção de sedimentos oriundos da atividade agrícola. Os solos estudados foram: 1. Um local Latossolo Vermelho Distrófico (Panamá, GO) cultivado em sistema de plantio convencional (SPC); 2 Dois locais Cambissolos Háplicos Eutróficos (Goiatuba e Jandaia, GO), cultivados sob sistema de plantio direto (SPD) e pastagem de braquiária. À jusante de todas as áreas de cultivo existem matas ciliares. Fez-se a descrição morfológica dos perfis do solo e testes de resistência à penetrometria. A seguir, coletaram amostras deformadas e indeformadas de terra, nas profundidades de 0-5, 5-10 e 10-20 cm de profundidade para as análises físicas e químicas. Na comparação de médias usou-se o teste de Tukey a 5%. Os sistemas de manejo do solo provocaram alterações nos atributos físicos e químicos, comparados com a mata ciliar, destacando-se: a) menor resistência à penetração sob sistema plantio convencional (SPC) no Latossolo Vermelho distrófico e maior nos Cambissolos Háplicos eutróficos, tanto sob sistema de plantio direto (SPD) quanto na pastagem; b) diminuição na agregação dos solos sob SPC e SPD e aumento sob pastagem; c) diminuição nos teores de matéria orgânica e cálcio sob todos os sistemas de cultivo. Nas descrições dos perfis de solo na mata ciliar foi constatada a presença de uma camada de material não pedogenizado sobre o horizonte A, proveniente de sedimentos produzidos pela erosão das áreas à montante, de onde foram retirados os terraços. As matas ciliares, à jusante das áreas cultivadas sob SPD e pastagem, por causa da ação antrópica e da largura inadequada, não foram capazes de reter satisfatoriamente os sedimentos; no SPC, a largura é adequada, atendendo às exigências legais brasileirasMade available in DSpace on 2014-07-29T16:24:20Z (GMT).
