“…In contrast, hydroponic systems potentially enable the induction of every mineral nutrient deficiency simultaneously in a controlled environment (Pitchay andMikkelsen 2017, 2018). These can generally be translated to plants grown in soil, such as with Summerhays et al (2015) growing P deficient plants in soil with similar results with plants growing in hydroponics (Summerhays et al 2017).…”

“…Although a wide array of these substances are abundant in the OM fraction of soil (>22,000 kg ha -1 per 1% OM), evidence suggests that directly blending or bonding these with P fertilizer can increase solubility and uptake, with resulting increases in crop yield (Tan, 2003;Hill et al, 2015a, b); Summerhays et al, 2015). The probability of response increases in soils having poor P solubility and with reduced rates of P fertilizer (Hopkins, 2015) and at low soil OM (Summerhays et al, 2015). Hopkins (2015) reported an average yield increase of 7% over a wide variety of crops.…”

The discovery and development of phosphorus (P) and P fertilizers provide context for current management conventions. Average crop yields were stagnant before the Green Revolution but have steadily increased since. This, along with conventional P management, has resulted in widely depleting soil P levels. Improved technology and management are needed to meet the increasing P demand. Modern hybrids and cultivars have different P demand and uptake patterns that require changes in conventional P fertilizer placement and timing. Phosphorus fertilizer recommendations based on soil analysis remains valid, but evidence suggests a need for recalibrating soil test P (STP) critical levels (the STP concentration at which a response to P fertilizer would not be expected) and P fertilizer rates to accommodate high‐yield scenarios. Considering higher P fertilizer rates as a single solution poses environmental challenges, highlighting the need for improved P use efficiency (PUE). Phosphorus fertilization approaches that have the potential to improve PUE and enable high yields include crop‐specific precision placement of P, informed timing of P fertilizers, and new enhanced efficiency sources of P fertilizer. This paper examines these management approaches from historical, production, and environmental perspectives in modern cropping systems. Core Ideas History of P fertilization illuminates traditional soil P management and needed changes. Recalibration of STP and P fertilizer recommendations are needed to match increasing yield and rates of P uptake. Environmental concerns and diminishing P supply necessitate improvement in P use efficiency. Placement and timing are improved through understanding of variable rooting patterns. Enhanced efficiency P fertilizers can be effective if applied correctly.

“…In addition, HS can improve the moisture retention in sandy soils (Selim et al, 2009). In plants, HS has an effect similar to that of auxin hormone, with improvements of the root system development (Canellas et al, 2002;Zandonadi et al, 2007) and activation of proton pump ATPases present in the cell membrane (Canellas et al, 2002;Mora et al, 2010), which results in an increased nutrient uptake (Eyheraguibel et al, 2008;Baldotto et al, 2009) and plant biomass production (Abu-Zinada & Sekh-Eleid, 2015). Specifically for potato cultivation, the use of HS associated, or not, with mineral fertilizer has resulted in increased vegetative growth, plant height, leaf area, and DM production (Abu-Zinada & Sekh-Eleid, 2015), increased wateruse efficiency, and specific gravity and starch content in tubers (Alenazi et al, 2016), and promoted the increase of potato tuber yield (Sanli et al, 2013;Alenazi et al, 2016).…”

The objective of this work was to evaluate the effect of humic substances (HS) and phosphorus fertilizer on the growth, P uptake, tuber yield, fertilizer P recovery (FPR), and applied P-use efficiency (APUE) of potato (Solanum tuberosum) cultivated in a sandy and in a clayey soils. In both soils, the experiment was carried out in a randomized complete block design, in a 4×3 factorial arrangement, with four replicates. The treatments consisted of four P rates (0, 100, 200, and 400 kg ha-1 P2O5) and of three HS rates (0, 50, and 300 L ha-1). Phosphate fertilization increased the P uptake and tuber yield of potato in both soils. Soil characteristics conditioned the effect of the addition of HS. In the sandy soil, with a lower content of organic matter (OM) than the clayey soil, the addition of HS increases the P uptake and FPR, besides providing a greater tuber yield and APUE, especially under the P absence or with the application of a reduced P rate. In the clayey soil, HS does not affect the response of potato to P fertilization.
