Phosphorus and potassium balance in soil under crop rotation and fertilization
(Universidade Estadual de Londrina (UEL), 2012-01-01)
The use of crop rotation and manure application can provide sustainability for an agricultural production system by improving soil quality and increasing nutrient use efficiency. This study aimed to evaluate the effect of ...
Determinations of phosphorus in fertilizers by spark discharge-assisted laser-induced breakdown spectroscopy
(2018-06-01)
A spark discharge system was coupled to laser-induced breakdown spectroscopy (SD-LIBS) to improve sensitivity in the determination of P in fertilizers. A LIBS system consisting of a Q-switched Nd:YAG laser operating at ...
Assessment of risk attached to recommendations

Increase of nitrogen-use efficiency by phosphorus fertilization in grass-legume pastures
(Springer, 2020-09-11)
Forage legumes intercropped with grasses add nitrogen (N) to the production system and may increase forage yields. However, both phosphate fertilization and the solubility of phosphorus (P) sources may affect this contribution. ...
Trace Element Composition of Selected Fertilizers Used in Chile: Phosphorus Fertilizers as a Source of Long-Term Soil Contamination
(TAYLOR & FRANCIS INC, 2009)
Anthropogenic activities like agriculture have resulted in increased concentrations of some trace elements of toxicological and environmental concern in soils. Application of fertilizers has been one of the major inputs ...
Formas de fósforo no solo após o cultivo de braquiária e tremoço branco
(2013-08-01)
Phosphorus is one of the major factor that limits agricultural productivity in most tropical soils. The objective of this study was to assess P transformations and availability in a soil cropped to brachiaria (Urochloa ...
PHOSPHORUS FERTILIZATION AND SOIL TEXTURE AFFECT POTATO YIELD
(Univ Fed Rural Semi-arido-ufersa, 2018-07-01)
Potato (Solanum tuberosum L.) is a nutritionally demanding crop, and phosphorus (P) is a nutrient that exerts a large effect on tuber yield. However, as the availability of P is influenced by soil texture, there are doubts ...
Teor de macronutrientes na parte aérea e sementes de plantas de alface em função de doses de composto orgânico com e sem adição de fósforo ao solo
(Universidade Estadual de Londrina (UEL), 2014)
Phosphorus fertilization of a grass-legume mixture: effect on plant growth, nutrients acquisition and symbiotic associations with soil microorganisms
(2015-09)
Adding P on Lotus tenuis and Festuca arundinacea, pure or mixed, on growth, nitrogen (N) and phosphorus (P) acquisition and associations with soil microorganisms was studied to investigate the establishment of Lotus for ...
