“…Notwithstanding plants possess a number of physiological adaptations that enhance P acquisition under conditions of low P availability. These included strategies that preserve internal P or those that increase the availability of P through the modification in root structure or function (Rausch and Bucher 2002;Richardson et al 2005) or even making a symbiotic association with specific microorganisms such as mycorrhizae (Shibata and Yano 2003).…”

Phosphorus (P) deficiency is one of the most important constraints to food production, particularly in tropical Oxisols. This study aimed to characterize the inorganic and organic P (Pi and Po) fractions in the soil in three smallholding coffee cultivation fields managed under either agroforestry (AGF) or full sun (FSC) agroecosystems. The work was carried out in areas situated at the municipalities of Divino and Araponga in the Zona da Mata in the state of Minas Gerais, southeastern Brazil. Soil P forms including H 2 O-Pi; NaHCO 3 -Pi,Po; NaOHPi,Po; diluted HCl-Pi; concentrate HCl-Pi,Po and Residual-P were sequentially extracted in samples from 0 to 5 and 5 to 10-cm soil layers. Together, H 2 O-Pi and NaHCO 3 -Pi accounted on average for only 4% of soil total P in the cultivated soils. HClconc.-Pi ranged from 142.8 to 372.4 mg kg -1 being the predominant Pi fraction. AGF systems promoted an increment of 8% in the NaHCO 3 -Po fraction in relation to the FSC systems in the upper soil layer. The AGF systems increased HClconc.-Po pool in relation to the FSC systems in Divino and Araponga(I) soils, indicating that agroforestry is an important management strategy to increase bioavailable P and for the maintenance of organic P pool. The distribution of inorganic and organic P pools varied among the different study sites, showing that P cycling depends on the inherent characteristic of each agroecosystem. The availability of P to plants in coffee-agroforestry fields is directly associated with the cycling of the organic P pool.

“…Arbuscular mycorrhizal fungi increases plant P uptake by reducing the distance ions must diffuse (Sanders and Tinker, 1973). Arbuscular mycorrhizal-dependent plants very often absorb and store more P than is required F to satisfy growth (Shibata and Yano, 2003;Pasqualini et al, 2007). Applying fertilizers is also gaining attention nowadays because of their importance for vigorous growth and higher yields of different plant species; however, their effect on soil pollution and non-target (beneficial) organisms, especially AM fungi, was seldom understood.…”

on linseed (Linum usitatissimum L.) growth response with phosphate solubilizing bacteria Pseudomonas fluorescens; different doses of superphosphate were used: 20 kg ha -1 (half recommended dose), 40 kg ha -1 (recommended dose), and 80 kg ha -1 (double recommended dose) in earthen pots filled with sterilized soil under greenhouse conditions. Among all the growth parameters, the following were the highest in the G. mosseae + P. fluorescens combination at the medium concentration (recommended superphosphate dose): plant height (78.74 ± 1.8 cm), fresh shoot weight (3.45 ± 0.294 g), dry shoot weight (0.57 ± 0.007 g), fresh root weight (0.223 ± 0.023 g), dry root weight (0.036 ± 0.004 g), root length (17.67 ± 0.48 cm), AM spore number (94.4 ± 9.86), shoot (1.14 ± 0.115%) and root (1.29 ± 0.110%) P content, and acidic (0.447 ± 0.012 IU g -1 FW) and alkaline phosphatase activity (0.119 ± 0.008 IU g -1 FW). The percentage mycorrhizal root colonization with the A. laevis + P. fluorescens (86.86 ± 2.17%) combination and chlorophyll content with the G. mosseae + A. laevis + P. fluorescens (0.474 ± 0.009 mg g -1 FW) combination recorded the highest values at the low concentration (half recommended superphosphate dose) as compared with non-mycorrhizal plants (control). The high superphosphate dose clearly reduced or decreased all the growth parameters. Therefore, vigorous growth and maximum flax yield can be achieved by inoculating plants with AM fungi and P. fluorescens with the recommended dose or less than the recommended dose of superphosphate.

“…Across the three inter-hedgerow alley width spacing evaluated, highest response in soil available P was recorded when the pigeon pea alleys were spaced 2 m apart. Other researchers elsewhere have reported similar increases in soil available P with application of pigeon pea treatment (Shibata and Yano, 2003;Sinclair, 2004). Research study conducted in India with rotation systems showed that pigeon pea not only increased the Nitrogen status of the soils but also increased the amount of Phosphorus available for the follow-up crops in the rotation (Sinclair, 2004).…”

Short term changes that occur in soil properties of an ultisol under different pigeon pea hedgerow alley populations and inter-hedgerow alley spacing and the effect of such changes on ginger rhizome yield response were evaluated in a two-year (2010 and 2011) field study in South Eastern Nigeria. Treatments comprised pigeon pea hedgerow alley populations of 20,000, 33, 333 and 66, 667 plants/ha in factorial combinations with three inter-hedgerow alley width spacing of 1, 2 and 3 m in a randomized complete block design with three replications. A plot having no pigeon pea component but planted to sole ginger constituted the control. Relative to the control, growing ginger in-between pigeon pea hedgerow alleys resulted in significant improvement in soil exchangeable Ca, Mg, and K, base saturation, organic carbon and available P in addition to reducing soil dry bulk density. Highest response in soil available P, organic carbon, dry bulk density, exchangeable Ca and Na and pH was achieved using pigeon pea population of 66, 667 plants/ha, while highest response for soil total N, base saturation and exchangeable K was achieved with 20,000 pigeon pea plants/ha. Optimum ginger rhizome yield response comparable with the control was achieved using pigeon pea hedgerow alley population of 20,000 plants/ha spaced 3 m apart. Increasing pigeon pea hedgerow alley population beyond 20,000 plants/ha and decreasing pigeon pea inter-hedgerow alley width below 3 m resulted in rhizome yield reduction due to probable nutrient competition. Apart from its capacity to continuously maintain the fertility of the fragile and infertile soils of South Eastern Nigeria, planting ginger in-between pigeon pea hedgerow alley will also serve as additional source of revenue to smallholder resource-poor ginger farmers in Nigeria.
