Soil microbial properties are improved by the adoption of soil management and conservation practices in no-tillage system
28/Nov/2023
ABSTRACT No-tillage system (NTS) plays a prominent role in conservation agriculture, however, its benefits can be further improved by adopting complementary soil management and conservation practices, such as using autumnal cover crops, contour seeding, and terraces. This study aimed to evaluate how soil biological activity responds to soil management and conservation systems. The treatments consisted of three macroplots with an area of 11.000 m2 each, as follows: a) Non-Terraced catchment (NTC), cultivated in NTS similar to most farmers of the […]
Comparison between two methods to estimate the surface runoff volume
01/Jun/2001
The estimative of the maximum surface runoff volume is fundamental to design several types of hydraulic structures as, for example, level terracing systems. The incorrect estimative of the surface runoff volume causes a wrong design of these systems and when overestimated present high installation cost. Considering these aspects, the present study aimed to compare the values of the surface flow maximum volume obtained by the empiric method of the curve number and developed by the USA Soil Conservation Service, with […]
