Phosphorus and potassium budget in the soil-plant system in crop rotations under no-till
Soil management and crop rotations can affect P and K budget in soil, decreasing losses, and increasing fertilizer use efficiency. The P and K budget in the soil-plant system at depths up to 60. cm was studied for different ...
Vegetative, productive and qualitative performance of grapevine "Cabernet Sauvignon" according to the use of winter cover crops¹.
(Revista Ceres, Viçosa, v. 63, n.4, p. 538-544, jul/ago, 2016., 2016)
Sistemas de culturas sob diferentes manejos por longa duração alteram as formas de fósforo do solo?
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2012-08-24)
The thesis objective was to evaluate the forms of accumulation and release of phosphorus from cover crops waste under long time of different soil management systems and its relationship with the soil phosphorus forms. The ...
Effects on soil and crop properties of forms of sowing, deferral intervals and fertilisation of the annual winter forage in a crop-livestock integration system.
(Journal of Agricultural Science, v. 8, n. 5, p. 15-25, 2016., 2016)
Brachiaria as a Cover Crop to Improve Phosphorus Use Efficiency in a No-till Oxisol
(Soc Brasileira De Ciencia Do Solo, 2016-01-01)
Oxidic soils are phosphorus drains in soil; hence, P availability is a limiting factor in tropical, weathered Oxidic soils. It has been shown that some brachiarias grown as cover crops may increase soil available P to ...
Early development and nutrition of cover crop species as affected by soil compaction
(Marcel Dekker Inc, 2003-01-01)
A good cover crop should have a vigorous early development and a high potential for nutrient uptake that can be made available to the next crop. In tropical areas with relatively dry winters drought tolerance is also very ...
Crop sequences in no-tillage system: effects on soil fertility and soybean, maize and rice yield
(Sociedade Brasileira de Ciência do Solo, 2009-04-01)
Os resíduos vegetais das culturas, ao se decomporem, alteram os atributos químicos do solo e, como consequência, influenciam a produtividade das culturas em sucessão. O objetivo deste trabalho foi avaliar os atributos ...
Identifying indicators of C and N cycling in a clayey ultisol under different tillage and uses in winter.
(Applied Soil Ecology, v. 76, p. 95-101, 2014., 2014)
Agricultural landscapes as habitat for birds in central Chile
(Sociedad de Biología de Chile, 2017-05-31)
Background: Understanding the role of agroecosystems as habitat for wildlife is crucial for long-term conservation planning, as different crop stratification and landscape elements can influence bird communities, which are ...
Soybean root growth and yield in rotation with cover crops under chiseling and no-till
(Elsevier B.V., 2010-10-01)
Compacted subsoil layers result in shallow root systems hindering the absorption of water and nutrients by plants. Disruption of soil compacted layers can be promoted by mechanical and/or biological methods, using plants ...
