Influência de composto orgânico e fósforo sobre sementes de alface
(Universidade Estadual de Londrina (UEL), 2012-01-01)
This study had aim to evaluate influences of organic compost and phosphorus on lettuce seeds (cv. Veronica), measuring production and quality parameters of seeds in this species. Experimental design was in randomized blocks ...
Phosphorus fractions as a function of the use of phosphate fertilizers in different soil classesFrações de fósforo em função do uso de fertilizantes fosfatados em distintas classes de solo
(2021-08-05)
Most Brazilian soils have low natural fertility. The main characteristic is phosphorus (P) deficiency and high P adsorption capacity. This creates the need to add phosphate mineral fertilizers, organic or organomineral. ...
Organic and inorganic forms of phosphorus in soils amended with sugar cane filter cake
(2020-01-01)
Studies of phosphorus (P) behaviour in soils receiving sugar cane filter cake are important for determining doses, its contribution to P nutrition and maximizing fertilizer efficiency, especially in soils with low P ...
