Bone meal as a source of phosphorus for forage sugarcane
(Univ Federal Goias, 2019-01-01)
Phosphate fertilizers of organic origin may represent a viable alternative for the replacement of mineral fertilizers in the nutrition of crops such as forage sugarcane. This study aimed to investigate the effects of ...
Formas de fósforo no solo sob utilização de estimulador microbiológico
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilAgronomiaUTFPR, 2017-06-20)
Phosphorus (P) is essential for plants, so the maintenance of their availability in the soil is fundamental, which occurs mainly with soluble mineral fertilization. However, the indiscriminate use of phosphate fertilization ...
Agronomic effectiveness of cationic phosphate impurities present in superphosphate fertilizers as affected by soil pH
(2006-10-01)
The general concept that low-water-soluble phosphorus (P) fertilizers should be more agronomically effective when applied to acidic soils was developed based on sources containing mainly calcium (Ca)-P compounds, but it ...

Plant stand, nodulation and seed yield in soybean as affected by phosphate fertilizer placement, source and application method
(2013-11)
Establishing an optimum plant population at planting is the start-point for assuring seed yield in crops. In addition to plant establishment, the onset of a fully functional nodule system is crucial for nitrogen nutrition ...
Corn fertilization with triple superphosphate in a Typic Hapludox soil under the residual effect of alternative phosphorus sources
(2018-01-01)
In variable-charge soils, the use of alternative phosphorus sources may influence further soluble phosphate fertilization. This study aimed to evaluate phosphorus (P) availability for corn plants in response to triple ...
