Cuban agriculture, to achieve the sustainability of agricultural systems, needs to initiate a transition process towards conservation agriculture practices; which implies a change in production systems and the technologies they use. Conservation agriculture (CA) implies a change in planting technologies and mechanized systems. Machinery specificall...

RESUMO - A prática de terraceamento evoluiu no Estado do Paraná a partir da década de 1970 e posteriormente o sistema plantio direto (SPD) foi sendo implantado ao longo dos anos na maior parte das áreas com culturas anuais. A eficiência do SPD em reduzir perdas de solo estimulou muitos agricultores a remover um terraço a cada dois ou todos os terra...
Chapter
This book is a comprehensive summary of current global research on no-till farming, and its benefits and challenges from various agronomic, environmental, social and economic perspectives. It details the characteristics and future requirements of no-till farming systems across different geographic and climatic regions, and outlines what is needed t...
Chapter
A high demand for food production has placed tremendous pressure on the finite land area and natural resources for agricultural production in different South America (SA) countries. Traditional agriculture in almost all SA countries places an emphasis on intensive tillage and monoculture, which has led to a severe environmental degradation and loss...

In agricultural areas all over the world, land in tropical and subtropical regions in general is intensively cultivated and, in most cases, the soil and water management systems are not practiced using an integrated and sustainable approach. In many farming systems where no orderly crop diversification, including cash crops and cover crops in a cro...
Article
Crop-yield variability is frequently associated with soil moisture and its real-time measurement can be an alternative for the automatic control of no-till seeding to improve soil-crop conditions. Soil moisture has a significant influence on soil behavior, markedly on its temporal and spatial variability; however, the measurement of soil moisture i...
Article
No-till is widely used to control soil erosion in agricultural areas in Brazil and is currently practiced on about 30 Mha. However, studies have shown that no-till is not as efficient in controlling surface runoff losses as it is in reducing soil loss. The objective of this study is to evaluate soil and surface runoff losses on small and large plot...

Vegetation cover on soil acts positively in maintaining temperature and soil moisture, yet, it has been imposing specific operational conditions on seeders. The objective of this study was to evaluate performance of different mechanisms regarding straw mobilization, employed in a no-till seeder. The experimental area was conducted on clayey soil un...
Article

Straw on sowing line modifies seed germination environment regarding temperature and water content. Given these considerations, the aim of this study was to evaluate different mechanisms for coverage mobilization on the sowing line and their effect on germination environment of maize seeds, mainly in relation to the dynamics of straw in the seedbed...

3 RESUMO: Na semeadura direta, é fundamental que a mobilização do solo no sulco de semeadura seja a menor possível, visando a reduzir o risco de erosão e de desenvolvimento de ervas infestantes. O objetivo do trabalho foi avaliar o desempenho de diferentes mecanismos para o manejo do sulco de semeadura quanto à mobilização de solo e à profundidade...
Article
Decreasing soil mobilization in no-till is essential in order to reduce the risk of soil erosion and the development of weeds. The objective was to evaluate soil mobilization and seeding depth by the action of mechanisms for residue management in the seeding row of a direct seeder. The experiment was conducted in a clay soil under no-tillage with 1...

Small farmers in various parts of Brazil, based the application of pesticides exclusively by a coastal manual sprayers. How it is simple equipment, there are few resources available to improve the quality of the application. The aim of this paper was to study the effect of air assistance, with manual override, in the deposition and percentage of co...

This book aims to provide an up-to-date state-of-the-art review on various aspects of Conservation Agriculture (CA) by reviewing the past and current research from various regions of the globe so that all others interested in CA could benefit from experiences gained under different agroclimatic and socio-economic conditions across the globe. This r...

The nontillage system has attained two million hectars in the State of Parana Brazil, in the last years, but one of the most important problems was the lack of suitable seeders to basaltic clay soils. Therefore, MAGNUM 2850 PD was studied as for energetic requirement and operational performance in order to fit it to the reality of the State of Para...
