Triticale, milheto e adubação fosfatada para formação de palhada em semeadura direta

Abstract: As fontes de P mais utilizadas são os fosfatos solúveis em água, pela maior facilidade de liberação de P no solo. Entretanto, devido às características dos solos tropicais, grande parte desse P acaba adsorvida às partículas do solo, tornando-se indisponível. Os fosfatos reativos podem, inicialmente, liberar o P de maneira mais lenta; entretanto, a partir dos cultivos, este elemento poderá ser liberado de forma contínua, podendo haver menor fixação. O objetivo deste trabalho foi estudar a resposta à aplicação d… Show more

“…The use of TSP may have facilitated fixation reactions with soil and plant uptake (Tables 1 and 2) due to fast release of P, especially in applications at high rates, which increases the adsorption reactions and immediate build-up of soil P and decreases PUE over time (Johnston and Syers, 2009). Similar results were found by Esteves and Rosolem (2011), depending on the source of P (TSP or NRP) broadcast.…”

“…: T. Mimmo, Y. Pii and F. Scandellari Sakurada et al, 2016), by incorporating new technologies of higher aggregate value. Research to increase the efficiency of P fertilization employing inexpensive sources, such as rock phosphate, is still scarce, and there are also reports of increased efficiency of P fertilization due to the use of cover crops, mainly annual ones (Esteves and Rosolem, 2011;Janegitz et al, 2016;Rodrigues et al, 2009;Rosolem et al, 2014).…”
