“…These results support the hypotheses that soil compaction decrease P diffusion flow, thus reduces ion-root contact and plant uptake. According to Barbosa et al (2018) the lower levels of P provided by broadcast fertilization P are justified by the low initial level of this nutrient in the soil, causing a reduction in the availability of P within the reach of the root. Amanullah and Almas (2012) affirmed the application of localized P enhances root system and provides upper contact with nutrients.…”

The efficiency of broadcast versus in line phosphate fertilization has been studied; however, soil density as a determining factor for soil efficiency has been less studied. Thus, the objective of this study was to evaluate the effect of broadcast and in line phosphate fertilization in soil with different densities on corn development. The experiment was conducted in pots under greenhouse condition. A completely randomized design was used in a 2x3 factorial arrangement with four replications. Treatments were two levels of soil densities (1.2 and 1.6 g cm-3) and three forms of P application (broadcast, in line and without P). Corn stem diameter, plant height, root volume, root and shoot dry matter, and root and shoot phosphorus content and accumulation were evaluated. Application in line resulted in higher P accumulation by corn plant. There was higher plant dry matter accumulation at soil density 1.2 g cm-3 than at 1.6 g cm-3. Phosphate fertilization in line at soil density 1.2 g cm-3 enhances dry matter accumulation in corn plants.

“…Among the determining factors for the best P application method are soil physical and chemical proprieties, fertilizer type and crop type (Ceretta et al, 2007). The phosphate fertilizer applied on the surface will keep contact with soil, causing the P fixation and affecting the absorption by the plants (Barbosa et al, 2018).…”

“…Phosphorus (P) availability has restricted crop growth in tropical acid soils due to the predominance of iron (Fe) and aluminum (Al) oxides in the soil fine fraction, which leads to P adsorption and P precipitation with Al and Fe (Vásconez and Pinochet 2018;Nascimento et al 2018;Matos et al 2017;Camargo et al 2013;). Both, P adsorption and precipitation, have negatively affected agricultural production in tropical conditions due to P unavailability (Barbosa et al 2018;Withers et al 2018;Yang et al 2012).…”

Soils are characterized by high phosphorus (P) immobilization, considering the major limiting factor for agricultural production in Brazil. Phosphate fertilizers complexed with humic acids (HA) have been presented as an alternative to inhibit P immobilization in soils; however, little is known regarding its efficiency or its effect on soil P dynamics when associated with liming. The objective was to investigate labile moderately and non-labile P changes in sandy and clayey soils under application of distinct P sources and liming. Tropical soils were incubated using 200 mg kg −1 of P (simple superphosphate-SSP and SSP + HA), associated or not with calcium oxide. Check-plots were run in both soils without any P addition and/or no liming. After 60, 90, and 180 days of incubation, P contents were fractionated into P inorganic (Pi) and organic (Po), in the following pools: labile (P AER and P BIC), moderately labile (P HCl and P HID-0.1), and non-labile fractions (P HID-0.5 and P residual). There was a P flux between non-labile and labile fractions, controlled by the use of P fertilizer and liming. In sandy soil, the P addition promoted a clear P flux from non-labile to labile fractions; however, in clayey soil, there was a reverse P flux. The lack of P addition promotes a negative balance in soil with a decrease of labile fractions, mainly when associated with liming. Therefore, inputs are necessary to avoid soil P depletion.

Microbial Solution of Growth-Promoting Bacteria Sprayed on Monoammonium Phosphate for Soybean and Corn Production

Common fertilizers present a low use efficiency caused by nutrient losses (e.g., through leaching, volatilization, adsorption, and precipitation in solution as well as through microbial reduction and immobilization) that create a significant limiting factor in crop production. Inoculation with Plant Growth-Promoting Bacteria (PGPB) is presented as an alternative to increasing fertilizer efficiency. The goal of the study was to test the hypothesis that PGPB (solution with Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis, and Bacillus pumilus) can be a strategy to increase the monoammonium phosphate (MAP) efficiency, root growth, and nutrient assimilation of soybean and corn cultivated in arenosol and oxisol. A greenhouse study was developed with the rates of PGPB (rates: 0, 1, 1.33, and 1.66–2.0 L per ton of fertilizer) sprayed on MAP and applied in an arenosol and oxisol cultivated with soybean and corn. Results showed that in both soils and crops, there was a variation in soil biological activity during the experiment. On day 45, PGPB + MAP promoted the beta-glucosidase and ammonium-oxidizing microorganism activities in the arenosol. The PGPB + MAP increased crop root growth in both soils and crops. Plant dry matter was associated with the phosphorous content in the soil, indicating that the phosphorous applied was absorbed by the plants, consequently resulting in a higher accumulation in the plant. Based on the results, the conclusion is that PGPB + MAP increases the growth and phosphorous accumulation of soybean and corn cultivated in the arenosol and oxisol, with a direct effect on crop rooting.
