“…It suggests a higher residual effect from FC and natural P source. This finding agrees with Caione et al (2012) who evaluated different P sources in sugarcane during 3 years and found that the soluble P source only provided significant increases in the first year, while the residual effect of insoluble P increased over time. In addition, the use of FC in sugarcane showed to be important for maintaining and increasing the sugarcane yield.…”

A field experiment was conducted from 2012 to 2015 aiming to evaluate two different P sources (TSP-triple superphosphate and NP-natural phosphate) associated with filter cake (FC) on soil microbial biomass, available P and sugarcane yield. The experiment design was a split-plot with four replications and consisted of different proportions of P sources: T1-100% TSP with FC; T2-100% TSP without FC; T3-66% TSP and 33% NP with FC; T4-66% TSP and 33% NP without FC; T5-33% TSP and 66% NP with FC; T6-33% TSP and 66% NP without FC; T7-100% NP with FC; T8-100% NP without FC. Application of filter cake increased soil microbial biomass and activity from the first to the third year. At the third year, the mixing of filter cake and TSP improved the status of microbial biomass and activity. Sugarcane yield did not show differences between treatments at the first and second years. However, at the third year, the application of FC associated with 33% of TSP and 66% of NP promoted highest sugarcane yield. In conclusion, the combination of both soluble and natural P sources associated with filter cake seems to be the best strategy for improving soil biological properties and increasing P availability and sugarcane yield in long-term.

“…The most widely used sources of phosphorus in coffee growing are the most soluble ones, due to the fast availability of this nutrient to plants (Caione et al 2012). However, this fast release may favor the nutrient adsorption and precipitation process by soil components, especially in clayey soils (Lourenzi et al 2014).…”

In the establishment of coffee crops, phosphate fertilization is one of the most important soil fertility managements. Aiming to minimize losses, among the options in use are fertilizers with a slow release of nutrients, combined with the inoculation of arbuscular mycorrhizal fungi (AMF). This study aimed to evaluate the initial growth of coffee plants inoculated with AMF and submitted to different types of phosphate fertilizers. The experiment was conducted in a greenhouse, using a complete randomized block design, in a 2 x 4 factorial scheme, with four replications. The first factor referred to the presence or absence of AMF (Rhizophagus clarus) and the second one to phosphate [monoammonium phosphate (MAP)], pelletized organomineral and grainy organomineral fertilizers, as well as a control (without fertilization). The plant height, leaf chlorophyll content, number of plagiotropic branches, leaf area, shoot and root dry matter mass, percentage of root colonization and leaf phosphorus were evaluated. The inoculation with AMF, associated with the pelletized organomineral fertilizer, provided a higher growth for the shoot and root system and higher phosphorus contents, in relation to the other treatments, and it can be an alternative to the implantation or renewal of coffee crops.

“…As a nutrient, P has been extensively investigated due to its importance to life, its frequent role as a limiting factor in crop production and its identity as a finite and irreplaceable mineral resource (Malavolta, 2006). It is the nutrient that most commonly limits crop production in Brazil (Caione et al, 2012). Fertilization with P fertilizers is needed to obtain good yields (Nachimuthu et al, 2009) sice most Brazilian soils naturally present a low P content.…”

Coffee Yield and Phosphate Nutrition Provided to Plants by Various Phosphorus Sources and Levels

Phosphorus (P) is considered one of the nutrients that most limits crop yields, especially in soils with an advanced degree of weathering. To evaluate P dynamics and availability in soil resulting from various P doses and sources and to assess the resulting P content of coffee leaves and the final coffee yield, an experiment was conducted in the municipality of Três Pontas, MG, Brazil, in a Red Argisol (Ultisol) area. Fertilization, except for P fertilization, was performed based on the soil analysis results. The annual P doses tested were 0, 75, 150, 300, 450 and 600 kg ha-1 P2O5. Two P sources, simple superphosphate and magnesium thermal phosphate, were evaluated and compared in the study. A physicochemical analysis of the soil and an analysis of leaf dry matter were performed. The available P content in the soil increased as a result of the applications of the two sources. The leaf P levels stabilized at approximately 1.8 and 1.9 g kg-1 for simple superphosphate and magnesium thermal phosphate, respectively, as a result of the application of approximately 300 kg ha-1 P2O5. The coffee responded to P fertilization in the production phase. Averaged over three harvests, the yield per harvest showed gains of 45.3% and 40.3% for simple superphosphate and magnesium thermal phosphate, respectively, with the application of the highest studied dose, 600 kg ha-1 P2O5.
