“…The increase in corn yield using Policote coated MAP was a consequence of the higher agronomic efficiency observed with this source of phosphorus. Similar results of higher plant growth, productivity and agronomic efficiency with Policote coated P fertilizer were also observed by Chagas et al (2015), Chagas et al (2016) and Guelfi et al (2018) in lettuce and coffee crops, respectively. Studies of enhanced efficiency fertilizers can bring advantages to several crops, including soybeans and corn that represent important crops for food production.…”

Due to the low natural availability of phosphorus (P) in tropical soils and the plant’s need for P, the use of phosphorus fertilizers of increased efficiency is an important tool for achieving high yields. The aims of this study were to evaluate plant growth, foliar P content and yield of soybean and corn crops in different seasons and places in response to P rates and sources. The sources of P were monoammonium phosphate (MAP) and Policote coated MAP (Policote+MAP). Field experiments were carried out comparing MAP performance compared to Policote coated MAP (MAP+Policote), an additive based on water soluble polymers. Experiments formed by P sources (MAP including 11% N, 52% P2O5 and MAP+Policote including 10% N, 49% P2O5) and rates were carried out in soybean and corn crops in different dates and sites. In the soybean crop, a (2x4) +1 factorial was used, comprising of two sources such as MAP and MAP+Policote and four rates of P (30, 60, 90 and 120 kg ha-1 of P2O5), besides the control. For corn, a (2x5) factorial was used, including two sources and five rates of P (0, 40, 80, 120 and 160 kg ha-1 of P2O5). The results showed that phosphorus fertilization would increase soybean and corn plant heights and yields in different seasons and places. Soybean and corn yield and agronomic phosphorus use efficiency were higher with Policote coated phosphorus fertilizer than with conventional phosphorus fertilizer. Policote coated phosphorus fertilizer can be used as an enhanced efficiency fertilizer because it increased soybean and corn yields in different seasons and places.

Soybeans and maize are the most cultivated crops in tropical soils and require large amounts of phosphate fertilizers. The use of enhanced-efficiency fertilizers is a promising technology to minimize losses of P by fixation in highly weathered tropical soils. The objectives of this study were to evaluate morphological characteristics, soybean P and boron foliar content, yield and agronomic efficiency of P fertilizer in response to P rates and sources in maize and soybean crops. Two P fertilization experiments with the sources Mono-ammonium Phosphate (MAP) and Policote coated MAP were carried out, one in maize (0, 20, 40, 80, 120 and 160 kg P2O5 ha-1) and another in soybean crop (0, 20, 40, 80 and 120 kg P2O5 ha-1). The morphological characteristics, soybean P and boron foliar content, yield and agronomic P fertilizer efficiency were evaluated. The results showed that maize and soybean morphological characteristics, as well as soybean foliar P and boron contents were not influenced by fertilization. P fertilization increased soybean yield. Policote coated MAP was more efficient than MAP (conventional fertilizer) to produce higher maize and soybean yields and higher agronomic efficiency of P use. For higher productivity, we recommend the dose of 102.9 kg P2O5 ha-1 of Policote coated MAP for soybean and 97.6 kg P2O5 ha-1 for maize.

“…Acidulated PR are the most used sources for fertilizer production, which release P very fast (Chien;Prochnow;Cantarella, 2009), causing sorption on soil particles and, consequently, reducing P uptake and the effectiveness of P fertilizer application (Kang et al, 2011). Recently, new technologies of phosphate fertilizer have been developed in order to enhance P use efficiency in soils, such as the incorporation of humic substances (Erro et al, 2016), coating with polymers (Sanders et al, 2012;Guelfi et al, 2018), pelletization or granulation with biochar (Kim;Hensley;Labbé, 2014), and pretreating or post-treating the biochar to produce enhanced biochar-based fertilizers (Yao et al, 2015;Lustosa Filho et al, 2017).…”

The use of fertilizers with some degree of protection of the phosphate ions can reduce soil adsorption and increase the absorption by plants, increasing the efficiency of phosphorus (P) fertilization. This study aimed to evaluate the performance of a phosphate fertilizer associated with biochar in granules in a P-fixing soil in a greenhouse experiment. Biochars were produced from two sources of biomass: sugarcane bagasse (SB) and wood sawdust (WS), which were pyrolysed at two temperatures (350 °C and 700 °C). After chemical and physical characterization, the biochar samples were granulated with triple superphosphate (TSP) in a 3:1 ratio (TSP: biochar). The agronomic evaluation of the fertilizers was carried out by two successive maize crops (Zea mays L.) in the greenhouse, using a factorial scheme of (5x3) in randomized block design with four replicates. The treatments consisted of five fertilizers (TSP-WS350, TSP-WS700, TSP-SB350, TSP-SB700, and TSP) and three P doses (100, 200, and 400 mg dm-3). It was evaluated the dry matter production, P uptake in maize and P available in the soil after cultivation. The results indicate that dry matter production, considering the P uptake by the plant and the P available in the soil when using a dose of 400 mg dm-3, presented higher results in both crop cycles and the recovery rate in both cultivations occurred inversely to the P doses. The simple association of biochar with soluble phosphate fertilizer did not increase the efficiency of P use by maize, but it increased available P in soil.
