1. Integrated use of sewage sludge and basalt mine waste as soil substitute for environmental restoration
Abstract If not managed properly, mining waste can be detrimental to the environment. In addition, sewage treatment plants produce sludge, a biowaste rich in organic matter which is often sent to landfills. The present study evaluated the use of sewage sludge as an amendment for mine waste from a basalt quarry as an alternative to the use of soil from borrow

3. Soil conservation management with cover crops: effects on critical energy levels, release and dispersion of aggregates
ABSTRACT The normalized dispersion index (NDI) and the b/a index are commonly used to express the stability of aggregates measured by ultrasound. However, few studies have used the critical energy (CE) extracted from modeling to explain the effects of soil use and management on soil aggregation. The objective of this study was to evaluate the influence of so

4. Winter Species Promote Phytoremediation of Soil Contaminated with Protox-Inhibiting Herbicides
RESUMO: A fitorremediação compreende uma das principais formas de descontaminação de substâncias orgânicas e inorgânicas no solo, economicamente viável e de baixo impacto ambiental. Objetivou-se com este trabalho verificar a eficiência de espécies vegetais de inverno na fitorremediação de solo contaminado com fomesafen e sulfentrazone, utilizando

5. Chemical Properties in Macroaggregates of a Humic Dystrudept Cultivated with Onion under No-Till and Conventional Tillage Systems
ABSTRACT Nutrients present in soil aggregates are essential for maintaining the productive capacity of agroecosystems and environmental quality. The aim of this study was to evaluate the chemical properties of macroaggregates of a Humic Dystrudept cultivated with onions under a no-till vegetable system (NTVS) compared to the conventional tillage system (CTS)

6. Cover Crops Effects on Soil Chemical Properties and Onion Yield
ABSTRACT Cover crops contribute to nutrient cycling and may improve soil chemical properties and, consequently, increase crop yield. The aim of this study was to evaluate cover crop residue decomposition and nutrient release, and the effects of these plants on soil chemical properties and on onion (Allium cepa L.) yield in a no-tillage system. The experiment

7. Pyricularia blast on white oats: a new threat to wheat cultivation
A newly emerged disease, the Pyricularia blast caused by Pyricularia grisea, is commonly observed on wheat and black oats, since its discovery in 1985. Within a few years the disease spread to other species of Gramineae, but white oat cultivars remained resistant and were the only ones among cultivated cereals resistant to this disease. In 2012, one commerci

8. Performance of Braford steers grazing on cultivated pastures and fed or not fed an energy supplement
This experiment evaluated the performance of 84 Braford steers grazing on summer and winter cultivated pastures fed or not fed an energy-protein supplement. Steers were 10 months old and weighed, on average, 165 kg at the beginning of the trial. Steers grazed on cultivated winter pasture, consisting of black oats (Avena strigosa) and ryegrass (Lolium multifl

10. Ãgua residuÃria de suinocultura aplicada em cobertura na cultura do milho com cultivo sequencial de aveia preta. / Swine wastewater applied as topdressing on maize crop followed by black oats
As taxas de aplicaÃÃo de Ãguas residuÃrias de suinocultura (ARS) utilizadas na produÃÃo agrÃcola devem ser suficientes para suprir a demanda das plantas por nutrientes. Justifica-se, entÃo, a necessidade de pesquisas sobre uso e manejo da Ãgua residuÃria de suinocultura como fertilizante, para que aplicaÃÃes sejam feitas de acordo com recomendaÃ

11. Use of conditioning in the production of black and white oat hay using two cutting heights
The study was conducted to estimate the dehydration curves, chemical composition, and occurrence of fungi in white oat hay (Avena sativa L. cv. Guapa BRS) and black oat hay (Avena strigosa Schreb cv. Common) at two cutting heights. Dehydration curves were studied under a randomized block design with a 2 × 2 factorial arrangement using split plots in time, c

12. DINÂMICA DO FÓSFORO NA INTEGRAÇÃO LAVOURA-PECUÁRIA SOB SISTEMA PLANTIO DIRETO / Phosphurus dynamic in crop livestock integration under notillage.
The necessity to preserve the soil, coupled with the constant search for lower production costs and increased productivity resulted in the use no-tillage (NT). Efficient technique in the preservation and use of highly weathered soils (tropical and subtropical soils). However, only the continuous cultivation of monocultures has been implicated in reduced prof
