“…It should be noted that the majority of these experiments was managed with pre-harvest burning and side-dress fertilizers incorporated into the soil. However, high yield increases were also reported for superphosphate applied over the trash blanket in low phosphorus Oxisols (Moberly & Wood, 1970;Zambrosi, 2021). Given the low mobility of phosphorus in the soil, particularly in Oxisols (Nunes et al, 2011;Sousa et al, 2016), in experiment 1, the efficient use of surface applied phosphorus by sugarcane is likely due to a high density of superficial roots in the soil-trash interface (Vitti et al, 2008;Castro et al, 2021), which is easily observed in sugarcane fields.…”

The objective of this work was to evaluate sugarcane (Saccharum spp.) yield in response to corrective and maintenance phosphorus fertilization in Oxisols. Two experiments were carried out in randomized complete blocks with four replicates. In the corrective fertilization treatments, 150 kg ha-1 P2O5 were broadcast and incorporated before planting. In the maintenance fertilization treatments, 40 kg ha-1 P2O5 per year were applied over the trash blanket. All treatments, except the control, were fertilized with 170 kg ha-1 P2O5 in the planting furrow. The first experiment was carried out in a sugarcane expansion area and the second, in a replanting area, in Oxisols with a low and high phosphorus availability, respectively. In the first experiment, corrective fertilization increased cane yield in 13.4 Mg ha-1 for plant cane and in 14.6 Mg ha-1 for the average of four ratoon crops, whereas maintenance fertilization increased yield in 17.7 and 8.1 Mg ha-1 for the average of four ratoon crops for the treatments without and with corrective fertilization, respectively. In the second experiment, there were no significant differences between treatments regarding yield. Corrective and maintenance phosphorus fertilization should be considered for sugarcane in areas where soil phosphorus availability is limiting.

“…The low efficiency of P fertilization has been reported in different papers [13] [14] [15] [16] [17]. It is estimated that the plants absorb only 15% to 25% of P applied via fertilizer [18] [19] [20]. On weathered and tropical soils, it can be necessary to apply up to five-fold more P as fertilizer than is exported in products [21].…”

Phosphorus (P) plays a crucial role in plant growth by aiding in the development of strong roots, promoting flower and fruit formation, and aiding in photosynthesis. Studies to improve P fertilizers efficiency in coffee orchards are necessary due to the need for better efficiency and the lack of information on enhanced efficiency P fertilizers. This study aimed to investigate the effect of MAP coated with anionic polymers (Policote) on coffee orchard development. A coffee trial was carried out in a randomized block design with three replications. The treatments, applied at coffee planting, were arranged in an incomplete factorial (2 × 4) + 1, using two P sources (MAP and Policote coated MAP), four P rates (40, 80, 120, and 160 g P 2 O 5 plant −1 ) and control (without application of P fertilizer). Plant height was evaluated in the 2016/2017, 2017/2018, and 2018/2019 seasons, while coffee bean maturation, yield, and agronomic P efficiency use were evaluated in the last two seasons. P fertilization did not affect coffee bean maturation and increased coffee yield in 31-month-old plants when differences among P sources and rates were observed. Using Policote-coated P fertilizer resulted in higher yields at the same P rate, as well as similar yields at a lower P rate, compared to conventional fertilizer. Policote-coated P fertilizer can be used as an enhanced efficiency fertilizer and is an efficient way to deliver required P to plants. The target for reducing farm investment, increasing agricultural profits, preserving phosphatic rock reserves, and avoiding the overuse of phosphate fertilizer could be realized through the rational use of enhanced efficiency fertilizers.

“…High phosphorus rates are applied at sugarcane planting, although the residual effect of this initial fertilization is insufficient to meet the crop requirements for subsequent years, causing a decline in ratoon cane yield [11,12]. Phosphate fertilization of ratoon cane is essential to meet the nutritional demand of the crop [13], and more efficient fertilizer sources are being sought, with fixation inhibitors or soil adsorption blockers, as an alternative to increase crop productivity or longevity [14]. Several strategies have been used to increase P fertilization efficiency.…”

Sugarcane Ratoon Yield and Soil Phosphorus Availability in Response to Enhanced Efficiency Phosphate Fertilizer

et al. 2022

The low availability of phosphorus in most Brazilian soils causes a heavy dependence of agricultural production on phosphate fertilizers, which are generally agronomically inefficient in tropical soils. Breeding for increased longevity of sugarcane ratoons is extremely important, but understanding how the efficiency of phosphate fertilization can be improved is equally necessary. The objective of this research was to evaluate the effects of phosphate fertilizers with and without polymer coating on the productivity and nutritional status of sugarcane ratoons and phosphorus availability in the soil. The experiment was carried out on a commercial sugarcane field on a dystrophic Ultisol over two growing seasons in a randomized complete block design with four replications. Two phosphorus sources (monoammonium phosphate (MAP) and MAP + Policote) were tested at four rates (20, 40, 60 and 80 kg P2O5 ha−1) in addition to the control (no P fertilization). The Policote-coated phosphate fertilizer induced higher stalk and TRS yields in the first experimental year, while the same effect was not observed in the second year. Nevertheless, with the reapplication of the treatments in the second study year, the mean stalk yield was high in response to the application of 20 kg P2O5 ha−1 of coated fertilizer and very different from that of the higher rates of the same fertilizer, which yielded 88 Mg ha−1, i.e., 8 Mg ha−1 more than the mean of the other rates.
