Least limiting water range in soil under crop rotations and chiseling
(Revista Brasileira de Ciência do Solo, 2011-05-01) [Artigo]
Soil water availability to plants is affected by soil compaction and other variables. The Least Limiting Water Range (LLWR) comprises soil physical variables affecting root growth and soil water availability, and can be ...
Soil water retention and s index after crop rotation and chiseling
(Revista Brasileira de Ciência do Solo, 2011-11-01) [Artigo]
Soil compaction can be minimized either mechanically or biologically, using plant species with vigorous root systems. An experiment was carried out with soybean (Glycine max) in rotation with triticale (X Triticosecale) ...
Soybean root growth and yield in rotation with cover crops under chiseling and no-till
(European Journal of Agronomy, 2010-10-01) [Artigo]
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 ...
Critical Periods of Storage of the Greenhouse Gases in Polypropylene Syringe
(Communications in Soil Science and Plant Analysis, 2017-08-06) [Artigo]
It is convenient to store gas samples containing e.g. carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), in polypropylene syringes before chromatographic analysis. However, there is no study of the integrity of ...
Phosphorus and potassium budget in the soil-plant system in crop rotations under no-till
(Soil and Tillage Research, 2013-01-01) [Artigo]
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 ...
Phosphorus and potassium balance in a corn-soybean rotation under no-till and chiseling
(Nutrient Cycling in Agroecosystems, 2013-05-01) [Artigo]
Nutrient use efficiency has become an important issue in agriculture, and crop rotations with deep vigorous rooted cover crops under no till may be an important tool in increasing nutrient conservation in agricultural ...
