P Mobilization

Arbuscular mycorrhizal (AM) fungi can ameliorate not only plant phosphorus (P) nutrition but also soil P mobilization, while P mobilization occurs secondarily and may in turn limit P acquisition at certain crop growth stages. It can be termed as the “mycorrhiza-inducible P limitation”, which has so far largely escaped study. A pot experiment was conducted to test the dynamic P acquisition of maize (Zea mays L.) at the vegetative growth stage and P mobilization in the soil in response to AM fungal inoculation in an unsterilized arable alkaline soil. The experiment included two fertilization levels and two AM inoculation levels, i.e., nitrogen (N), P, and potassium (K) fertilization (NPK) and non-fertilization (control), as well as Funneliformis mosseae inoculation (+M) and non-inoculation (–M). Regardless of fertilization, +M increased mycorrhizal colonization and plant biomass at weeks 4 and 8 but increased tissue P concentration only at week 4 compared with those of –M. In addition, the plant P acquisition and shoot biomass in the control+M treatment at weeks 4 and 8 were close to and much lower than those of NPK–M, respectively. Furthermore, the increase in soil P mobilization potential, which was achieved by the accelerated soil alkaline phosphatase activity and the decreased soil pH, was lower than the increase in root P-acquiring efficiency, which was achieved by the enhanced mycorrhization and ZEAma;Pht1;6 (a mycorrhiza- inducible Pi transporter in maize root) expression. Regardless of fertilization, +M thus significantly decreased soil available P concentrations compared with those in the –M treatments. Therefore, there was a large, real gap between soil P mobilization and root P acquisition in response to enhanced root mycorrhizal colonization, substantially limiting plant P acquisition and growth.

Fertilization efficiency which could enhance soil productivity is determined by type, application method and appropriate dose of fertilizers.  A green house experiment to study effect of different maturity level of ela  sago bokashi and some dosage of  SP-36 fertilizer on P-uptake and growth of maize (zea mays l.) on ultisols has been performed. The experiment was set up in three-replicates factorial Randomized Block Design. The treatments were  three maturity level of ela sago bokashi i.e. 2, 3 and 4 weeks; and four dosages of SP-36 fertilizer i.e. 0, 2, 4 and 6 g/10 kg of soil. The results showed that application of bokashi regardless of their maturity at the same time with each  doses of SP-36  increased P uptake, plant height and stem diameter of maize. Giving four-week ela sago bokashi with 6 gr/10 kg of soil of SP-36 was the best treatment to improve P uptake, plant height and stem diameter of corn crop up to  0.15%, 140, 60 cm and 1.64 mm respectively.

Sites co-contaminated with organic and metal pollutants are common and considered to be a more complex problem, as the two components often have a synergistic effect on cytotoxicity. This study investigated the dissipation mechnisms for pyrene in cadmium co-contaminated soil in which maize (ZEA MAYS L.) was grown in a greenhouse experiment. Results showed the growth response of maize may be affected by the co-contamination due to the interaction between the heavy metal and organic pollutants. Pyrene in both planted and unplanted soil diminished significantly at the end of 60-day culture, accounting for 21-31% of the initial extractable concentration in unplanted soil and 12-27% in planted soil, which indicated that the dissipation of pyrene was enhanced by the presence of vegetation. Although the presence of cadmium stimulated the accumulation of pyrene in roots and shoots of maize, contributions of plant off-take of pyrene to the total remediation enhancement in the presence of vegetation was less than 0.3%. A significant positive correlation was observed between soil enzyme activities (dehydrogenase, polyphenol oxidase) and the removal ratio of pyrene. Plant root exudates appear to promote the number of rhizosphere microorganisms and enzyme activity, thereby improving biodegradation of pyrene.

The effect of soil moisture level and phosphorus fertilization on corn (Zea mays L.) growth and P uptake was evaluated in a pot experiment under greenhouse conditions. Two soils, Lewisburg silt loam (fine, mixed, mesit, Typic Hapludalf) and Nipe clay (clayey, oxidic, isohyperthermic, Anionic Acrudox) were included in the study. The three moisture levels were M2 = field capacity, M2 = fluctuation between field capacity and 50% available water, and M3 = fluctuation between field capacity and permanent wilting point. The phosphorus treatments were P1 = 0 kg P/ha, P2=112 kg P/ha and P3 = 224 kg P/ha. Fresh and dry matter yield of corn plants grown on Lewisburg soil increased significantly with phosphorus fertilization. The field capacity treatment (M1) significantly outyielded the other two moisture treatments when 11 2 kg P/ha was applied. At 224 kg P/ha there was no significant difference in yield between M1 and M2 treatments, but both these treatments significantly outyielded the M3 treatment. Corn plants grown on Nipe soil did not respond to phosphorus or moisture treatments. Phosphorus applications to Lewisburg soil significantly increased phosphorus uptake by corn plants. Phosphorus uptake was 3.89, 21.60 and 42.73 mg/pot for 0, 112 and 224 kg P treatments, respectively. An increase in moisture stress decreased P uptake with M1, M2 and M3 yielding 27.88, 22.91 and 17.42 mg P/pot, respectively. Corn plants grown on Nipe soil showed a slight increase in P uptake with the application of 224 kg P/ha. but this increase was not significantly different from that of the other two P treatments. Nor did moisture stress affect P uptake. The lack of response of corn plants to P fertilization and moisture level of Nipe soil can be attributed to a high P fixing capacity of the soil.

Inceptisol is a young and newly developed soil so it needs to be optimized for crop cultivation. The aim of this research is to know the availability of soil P, P uptake and corn yield after application of granular composting of sago waste (KGES) together with phosphate fertilizer to Inceptisols soil. The experimental treatment was KGES which consisted of three levels: without KGES, 40 tons KGES ha-1, and 80 tons KGES ha-1, and the use of SP-36 (P) fertilizer consisting of three levels: without P fertilizer, 120 kg P ha-1, and 240 kg P ha-1. The experiment used a complete randomized design with 3 replications. The result of the experiment was analyzed variance and relationship test using interlaced analysis. The results showed that KGES together with phosphate fertilizers could increase soil pH causing phosphate to be available and plant roots could absorb nutrient phosphate well, so that the yield of corn kiln dry weight also increased. The highest yield of dry weight of grains (7.85 tons per ha) was obtained from a combination of 80 tons of KGES ha-1 and 240 kg P ha-1.Keyword: Keywords: Ella Sago, Inseptisols, maize, phosphate

Low P fertilizer efficiency can be attributed to a reduction in solubility due to P reactions with soil components. Added organic material may reduce such reactions and improve P fertilizer efficiency. Lignosulphonate (LS), a by-product of the pulp and paper industry, could have beneficial effects on fertilizer P. Effects of ammonium lignosulphonate (ALS) and diammonium phosphate (DAP) on corn (Zea mays L.) P uptake, extractable P and P fractions were measured. Soil P fractions were determined using a field incubation technique to simulate banded P applications in two Humic Gleysols, a Ste. Rosalie clay soil and an Ormstown silty clay loam soil. Soil organic C increased with increasing ALS addition and decreased with DAP additions. ALS had little effect on native soil P fractions. When applied with DAP, increasing rates of ALS increased Mehlich-III extractable P, 0.5 M NaHCO3 and 0.1 M NaOH extractable inorganic P, reduced 1.0 M HCl extractable P and had no effect on organic P extractable in 0.5 NaHCO3 and 0.1 M NaOH. Applying ALS at rates up to 300 kg ha−1 with P at 60 kg P2O5 ha−1 may improve uptake by corn of fertilizer P, but using ALS alone does not improve native soil P availability.

Soils of the tropics are highly weathered, acidic, and low in phosphorus (P) because of high contents of Al and Fe. Satisfactory P supply is essential to ensure optimum soil and crop productivity. Thus, there is a need for amending soils with zeolite to improve availability of P in acid soils as this mineral can fix Fe and Al instead of P. This study was undertaken to determine the transformations of P fertilizers in acid soils following application of Clinoptilolite zeolite (CZ) in laboratory (incubation) and pot trials. An acid soil was incubated with a recommended fertilization rate and a reduced amount of the existing recommended fertilization by 25% but substituting this reduction with an equivalent amount of CZ. Triple superphosphate (TSP), Egypt Rock phosphate (ERP), and Christmas Island Rock phosphate (CIRP) were used as P sources. Selected soil chemical properties, inorganic P fractions, available P, and total P of the native soil were determined before and after the laboratory and pot trials. Zea mays L. (test crop) plant dry matter production, P concentration, P uptake, and P use efficiency were also determined using standard procedures. Effects of the treatments with CZ compared to the recommended fertilization on P fixation were similar. In the laboratory study, the treatments with TSP showed lower dominance of Fe–P but more pronounced in Al–P, whereas for the RPs, Ca–P was dominant. In the pot study, Al–P, Ca–P, and Fe–P were rather pronounced in the treatments with TSP, ERP, and CIRP, respectively. There was a decrease in exchangeable Al and soil titratable acidity because of the ability of the CZ to increase soil pH. Although the availability of P was not significant with the inclusion of CZ in the incubation study, dry matter production, P concentration, P uptake, and P use efficiency in the pot trial were comparable with that of the existing/recommended fertilization, suggesting that the CZ is beneficial and could be used to reduce the P fertilizer requirement for Zea mays L. cultivation on acid soils. Regardless of type of P fertilizer, prevalence of the moderately labile P fractions (Al–P, Fe–P, and Ca–P) of the incubation and pot studies acted as slow-release P sources to contribute to long-term P release. Further studies on the potential of CZ to reduce fertilization and its effects on soil and crop productivity are essential. It is also important to determine the economic benefits of including CZ in Zea mays L. cultivation.
