Water erosion is responsible for soil, water, carbon and nutrient losses, turning into the most important type of degradation of Brazilian soils. This study aimed to evaluate the influence of three cover plants under two tillage systems on water erosion control in an Argisol at south of Minas Gerais state, Brazil. The cover plants utilized in the study were pigeon pea, jack bean and millet, under contour seeding and downslope tillage. Experimental plots of 4 x 12 m, with 9% slope, under natural rainfall were used for the quantification of losses of soil, water, nutrients, and organic matter. One experimental plot was kept without plant cover (reference). Higher erosivity was observed in December and January, although a great quantity of erosive rainfall was detected during the whole raining period. Contour seeding provided a greater reduction of water erosion than downslope tillage, as expected. The jack bean under contour seeding revealed the lowest values of soil, water, nutrients and organic matter losses.Index terms: Soil conservation, tillage systems, vegetal cover, erosivity. RESUMOA erosão hídrica é responsável por perdas de solo, água, carbono orgânico e nutrientes, sendo esta a principal forma de degradação dos solos brasileiros. Dessa forma, objetivou-se, com este trabalho, avaliar a influência de três plantas de cobertura, em dois sistemas de manejo, no controle da erosão hídrica em um Argissolo, no sul de Minas Gerais. As plantas de cobertura utilizadas foram o feijão-guandu, feijão-de-porco e milheto, em dois sistemas de manejo (plantio em nível e em desnível no sentido do declive), sendo que uma parcela sem cobertura vegetal foi mantida como testemunha. Para a quantificação das perdas de solo, água, carbono orgânico e nutrientes utilizaram-se parcelas de 4 x 12 m em que a maior dimensão obedeceu ao sentido do declive, de 9 %, sob chuva natural. Os meses de dezembro e janeiro apresentaram a maior erosividade, porém elevada quantidade de chuvas erosivas foram detectadas durante todo o período chuvoso. O plantio em nível proporcionou maior redução da erosão hídrica em comparação ao plantio em desnível, conforme era de se supor. O feijão-de-porco cultivado em nível obteve os menores valores de perdas de solo, água, nutrientes e matéria orgânica.Termos para indexação: Conservação do solo, sistemas de manejo, cobertura vegetal, erosividade.

“…However, the effect of zero or minimal tillage without the combination of straw mulching, including uneven nutrient availability, nutrient deficiency in late growth stages and yield depression, becomes negative (Hammel, 1995;Gao and Li, 2005;Govaerts et al, 2005;Xie et al, 2007). Therefore, it is important to understand the effects of combining zero or minimal tillage, straw mulching and rotation tillage since they have major impacts on production in conservation agriculture (Govaerts et al, 2005;Wang et al, 2006). Govaerts et al (2005) and Riley et al (2008) studied the long-term effects of different tillage methods or one crop production system on dry land and found complex interactions of crop growth and yield with tillage, straw mulching, and rotation tillage.…”

“…The same was valid for the C/N ratio under constant use of systems with partial or no turning of the soil layer (the 2nd, 3rd and 4th system) and under alternation of plowing and disking (the 6th system). The magnitude of the effect of long-term use of different types of tillage is driven by soil properties [19][20][21][22], the timing and frequency of tillage events [23,24], climate [6,25] and choice of crop [26][27][28].…”

This paper aimed at studying the effect of different types of soil tillage systems on the change of total carbon (C) and nitrogen (N) in the soil structural units of different size after dry structural analysis of soil. The research was carried out in a 6-field rotation system (grain maize-wheat-sunflower-wheat-bean-wheat) at the end of the 2nd rotation. Six out of 24 soil tillage systems were selected; they were applied independently and in combination in the crop rotation. After that, they were compared to the system with constant deep plowing. So a total of seven soil tillage systems were investigated. The selected systems for main soil tillage were the following: plowing (control variant), disking, cutting, nil tillage (direct sowing), plowing-disking, plowing-nil tillage, disking-nil tillage. Three depths of 0-10, 10-20 and 20-30 cm were studied, as well as soil structural units were of the following sizes: > 10 mm, 10-5, 5-3, 3-1, 1-0.25 mm and < 0.25 mm. As a result of systematic implementation of different soil tillage systems, higher N and C concentrations were established by the layers according to constant plowing. Constant disking and its alternation with nil tillage increased the total N concentration with 15.6% and 11.1%, respectively, in comparison with the constant plowing. The same was valid for C concentration in soil, but the highest increase was established in the variants with constant cutting and nil tillage. The exceeding was with 14.0% and 13.2%, in comparison to constant plowing. The redistribution of N and C depending on the structural soil units was most expressed in the 0-10 cm and 10-20 cm layers. The highest amounts of C and N were found in the soil units with size less than 5 mm, mainly in the < 0.25 mm fraction. At depth of 20-30 cm, the role of the size of soil structural units for C and N redistribution decreased strongly. The values of C/N ratio were moderate only under the use of constant disking. This index was low under all other soil tillage systems. The correlation of total N with C in soil was high, positive and significant depending on the size of structural soil units and the tillage systems, as average for the investigated factors in this experiment. The minimal tillage and the tillage without turning of soil, used independently and in combination, had the highest contribution to preserving the organic matter in the haplic Chernozems of Dobrudzha region.
