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.

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.

Soil Preparation

Mechanical soil management has a huge impact on early plant development and can promote effects at all stages of the silage forage production cycle. Thus, this work was conducted to verify if a mechanized system of soil preparation influences the accumulation of pigeon pea and corn biomass. The experiment was conducted at the farm school of Federal University of Mato Grosso do Sul, Faculty of Veterinary Medicine and Animal Science. The experimental delimitation chosen was randomized blocks, the treatments were two systems of tillage (conventional and reduced), associated to two crops (Cajanus cajan L., cv. BRS Mandarim e Zea mays L. hybrid TG Status). The cv. BRS Mandarim in conventional tillage system impacted higher biomass values. In addition, the same soil preparation system promoted oscillations between the crops (P<0.05), where cv. BRS Mandarim showed biomass values 7% higher than cv. Status TG. In reduced handling system, the crops presented the same biomass productivity. Despite the increase of dry weight during the cycle of cv. BRS Mandarim biomass production, there was a reduction in the dry matter fraction, indicating that the specific weight per plant decreased at the end of the evaluation period. The tillage system that was fulfilled conventionally promoted higher estimates of pigeon pea biomass. Corn was not influenced by mechanized tillage system.

Use Efficiency

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.
