“…Similar results were reported in previous studies (Fernández and Schaefer, 2012;Mallarino and Borges, 2006). Comparing residual P from NT-BR vs. ST-DB, the results from this study suggest that deep band fertilization has lower potential for runoff and environmental P loses (Hale et al, 2015;Nkebiwe et al, 2016). Other P placement management practices did not affect significantly soil P levels in the soil profile.…”

“…Phosphorus fertilizer placement has been widely studied in recent years, due to low P use effi ciency from fertilizers (Nkebiwe et al, 2016), and a worldwide concern about natural resource conservation (Fan et al, 2011). However, soils and climate factors can have a direct eff ect on P availability and use effi ciency, and therefore the results from diff erent studies can vary.…”

Phosphorus fertilizer placement can have signifi cant agronomic and environmental implications in long-term no-till (NT) systems. Th e objective of this study was to evaluate soybean [Glycine max (L.) Merr.] response to P fertilizer placement strategies under long-term NT management. A fi eld study was performed near Nao-Me-Toque-RS (Location 1) and Sao Sepe-RS (Location 2), southern Brazil, during the 2014/2015 growing season. Th e experimental design was a randomized complete block with three replications. Triple superphosphate was applied using fi ve strategies: (i) strip tillage with deep band (ST-DB); (ii) strip tillage with band-applied 5 by 5 cm (ST-B); (iii) no-till with broadcast (NT-BR); (iv) no-till with band-applied 5 by 5 cm (NT-B); (v) and no-till with surface band (NT-SB). Plant height, dry weight, and P uptake were evaluated at 20, 40, 60, and 80 d aft er emergence (DAE) as well as P removed and grain yield at harvest. Th e ST-B application promoted greater plant height, dry weight, and P uptake at 80 DAE. However, ST-DB showed the greatest P removal compared to other treatments. Also, greater yields were obtained for ST-DB and NT-BR. Soil sampling aft er harvest showed that ST-DB increased soil test P levels by 19 and 11% at the 15-to 25-cm layer for Locations 1 and 2, respectively. While NT-BR increased soil test P by 43 and 36% at the 0-to 5-cm layer for Locations 1 and 2, respectively. Deep band P fertilizer placement maintained or increased soybean yield and P use under long-term NT in tropical soils.

“…Subsurface placement of manures or mineral fertilizers produces higher crop nutrient uptake and yield than conventional surface broadcast [1][2][3][4]. Among others, intense rooting in nutrient patches and increased nutrient uptake rates favour exploitation of subsurface fertilizer depots.…”

“…Therefore, providing high concentrations of nutrients that stimulate root growth at the site of root contact (e.g. NH 4 + and HPO 4 2− /H 2 PO 4 − or CO(NH 2 ) 2 and HPO 4 2− /H 2 PO 4 − , the later under optimal ammonification conditions) [2,5] and are poorly mobile in soil [6][7][8][9], crops can more efficiently acquire fertilizer-depot nutrients, thus improving their yields [4]. Nevertheless, it has been shown that intense rooting may not occur around fertilizer depots based on manure or mineral N under greenhouse and field conditions [10]; (Müller et al 2009, unpublished results).…”

Background: Populations of plant growth-promoting microorganisms (PGPMs) inoculated in natural soil typically decline over time due unfavourable biotic and/or abiotic factor(s). Improving subsurface root density may enhance PGPM establishment due to high concentrations of organic nutrients released as root exudates. Placing subsurface root-attracting NH 4 + -fertilizer depots may form such zones of dense localized rooting ("rhizosphere hotspots") that can enhance PGPM survival. Nevertheless, required soil conditions that favour formation of rhizosphere hotspots are unknown. This study aimed to investigate: (1) background soil N min effect on NH 4 + -depot-zone root growth; (2) PGPM tolerance to high NH 4 + concentrations (± nitrification inhibitor, DMPP); (3) ability to solubilize sparingly soluble inorganic phosphates; (4) and establishment in a subsurface NH 4 + -depot. Methods:We conducted a greenhouse rhizobox experiment using spring wheat (Triticum aestivum L.) to investigate the effect of background N min (0, 5, 20 and 60 mg N kg Conclusion:These results show the first promising effects of combining fertilizer placement and application of P-solubilizing PGPMs on plant growth.
