Gafsa rock phosphate and triple superphosphate for dry matter production and P uptake by corn

Crops in general make poor use of phosphorous fertilizer and, as a result, recommended rates and production costs are very high. Phosphorus can be made more readily available to plants by proper management of phosphate fertilization, selecting both, type of fertilizer and application method. This study was carried out to evaluate the efficiency of the natural Gafsa rock phosphate and the triple superphosphate on dry matter production and P uptake by corn plants cultivated in a greenhouse. Fertilizers were applied localized and broadcast/incorporated on to two soils with contrasting phosphorus capacity factors (PCF). Rock phosphate broadcast application was as efficient as triple superphosphate in increasing corn plant dry matter in the Tropudult, with lower PCF. This effect was not observed on the Haplustox, owing to the lower P solubility due to the higher Ca concentration in this soil. Triple superphosphate rates increased plant P uptake in both soils and for both application forms. Rock phosphate resulted in higher P-content in plants, but only for broadcast application on the Ultisol.

In field studies in 1992 and 1993, biosolid applications of 2 t/ha with supplements of mineral N and P were compared with a standard mineral fertiliser application (20 kg N/ha, 20 kg P/ha, 1.8–2.8 kg Zn/ha, 1.4–1.9 kg Cu/ha, 0.5–4 kg Mn/ha) on 4 soil types. Biosolid rates from 2 to 10 t/ha were applied in 1993. Shoot dry matter production at different stages of plant development (9 and 15 weeks after sowing) and grain production of Triticum durum and Hordeum vulgare, as well as nutrient concentration in shoots and grain, were taken as indicators for comparing nutrient availability of the 2 sources. A 2-t biosolid application was found to enhance dry-matter production and yield to the same extent as a mineral fertiliser application of 20 kg N/ha, 20 kg P/ha, and 1.8–2.8 kg Zn/ha. In some crop rotations and on sites with a high yield potential, additional nitrogen with 2 t biosolids/ha would be necessary to achieve such yields. However, development of durum wheat fertilised with 2 t biosolids was slower and P uptake lower than with mineral fertiliser until late booting. Durum wheat fertilised with 4 t biosolids showed similar P-uptake values as plants fertilised with the mineral fertiliser. The Zn-uptake of plants was positively correlated with biosolid application rates, showing a linear relationship. A 2-t biosolid application alleviated micronutrient deficiency to the same extent as the same rate of Zn (and Cu) given in mineral form.

Lotus Pedunculatus

The effects of inoculation and pelleting, with two storage periods, were investigated on the establishment of 'Grasslands Maku' Lotus pedunculatus at three sites. When seeds were sown one day after treatment, none of the treatments gave consistently better establishment than inoculationonly, although the addition of gum arabic adhesive alone significantiy increased establishment on one site. However, after 15-day storage of the seed, establishment was higher from gum arabic adhesive alone than from inoculated-only seed although the effect attained significance on only two sites. In contrast, establishment of pelleted seed, apart from rock-phosphate/dolomite on one site, was similar to or less than that from inoculated-only seed. There was a consistent trend for all pelleting treatments to give a lower degree of establishment than did gum arabic adhesive alone. Lotus dry matter production in the second growing season was measured on one site and the importance of maximizing establishment was demonstrated by the marked treatment effects on lotus yield.

Greenhouse and field experiments were conducted to evaluate the effect of inoculation with a phosphate-solubilizing isolate of Penicillium bilaji on the yield and phosphate uptake by canola (Brassica napus L.). Under greenhouse conditions, P. bilaji inoculation did not affect canola pod or straw dry matter production, but did increase straw and pod P concentrations resulting from increased P uptake over uninoculated treatments. Addition of P at 20 mg kg−1 soil as Florida rock phosphate plus inoculation with P. bilaji resulted in P uptake by canola nearly equivalent to that resulting from the addition of monoammonium phosphate (MAP) alone at the same rate of P. Addition of Florida rock phosphate alone had much less effect on plant P uptake. Addition of P. bilaji generally increased dry matter yields and P uptake by canola in two field sites. Penicillium bilaji appears to be able to increase the uptake of P from sources unavailable for plant uptake; P uptake by control plants inoculated with P. bilaji absorbed as much P as that absorbed by uninoculated plants receiving MAP.

ABSTRACT The use of fertilizers with some degree of protection of the phosphate ions can reduce soil adsorption and increase the absorption by plants, increasing the efficiency of phosphorus (P) fertilization. This study aimed to evaluate the performance of a phosphate fertilizer associated with biochar in granules in a P-fixing soil in a greenhouse experiment. Biochars were produced from two sources of biomass: sugarcane bagasse (SB) and wood sawdust (WS), which were pyrolysed at two temperatures (350 °C and 700 °C). After chemical and physical characterization, the biochar samples were granulated with triple superphosphate (TSP) in a 3:1 ratio (TSP: biochar). The agronomic evaluation of the fertilizers was carried out by two successive maize crops (Zea mays L.) in the greenhouse, using a factorial scheme of (5x3) in randomized block design with four replicates. The treatments consisted of five fertilizers (TSP-WS350, TSP-WS700, TSP-SB350, TSP-SB700, and TSP) and three P doses (100, 200, and 400 mg dm-3). It was evaluated the dry matter production, P uptake in maize and P available in the soil after cultivation. The results indicate that dry matter production, considering the P uptake by the plant and the P available in the soil when using a dose of 400 mg dm-3, presented higher results in both crop cycles and the recovery rate in both cultivations occurred inversely to the P doses. The simple association of biochar with soluble phosphate fertilizer did not increase the efficiency of P use by maize, but it increased available P in soil.

Clinoptilolite Zeolite

Insufficient supply of P for initial growth of crops does not only limit N uptake but it also leads to poor yield of crops. In acidic soils of the tropics, sorption of P occurs mainly on surfaces of Fe and Al oxides and hydroxides. Most of the P added through mineral fertilizers is fixed by high Al and Fe oxide concentrations and transformed into insoluble P compounds. Reduction of Al and Fe is important so as to ensure adequate supply and readily available P for crops uptake. A number of studies using zeolites as an amendment in the fertilization programs of crops have improved crops production, nutrients uptake, and nutrients use efficiency. However, there is dearth of information on the use of clinoptilolite zeolite (CZ) to reduce P fixation not to mention reduction of N, P, and K fertilizers use in agriculture. This study was conducted to: (i) determine dry matter production, nutrients concentration, nutrients uptake, and use efficiency of Zea mays (Hibrimas variety) by including CZ in the fertilization program of Zea mays planted on an acidic soil, and (ii) determine the effect of including CZ in the fertilization program of Zea mays on selected chemical properties of an acidic soil. Egypt rock phosphate (ERP), urea, and muriate of potash were used in this study. Seventy five percent (w/w) of the recommended N, P, and K fertilizers for Zea mays were combined with CZ. Standard procedures were used to determine soil pH, inorganic nitrogen, available phosphorus, exchangeable aluminium, iron, potassium, calcium, magnesium, and organic matter before and after planting. Zea mays were harvested at tasselling stage and measured for dry matter production, nutrients uptake and use efficiency. The effect of CZ application with 75% of fertilizers (E2) and 100% fertilizers (E1) were statistically similar for selected soil chemical properties, dry matter production, nutrients concentration, uptake of nutrients, and nutrients use efficiency except for N. Nitrogen use efficiency for E2 was better than that of E1. These findings suggest that adoption of CZ with 25% reduction of N, P, and K fertilizers are useful. Further field trials and economic analysis are recommended to confirm the findings of this study. These aspects are being investigated in our on-going field experiments.

Manganese Level

The possibilities of ameliorating manganese-induced chlorosis with boron applications were studied under greenhouse conditions using soybean and corn as indicator plants. Five levels of boron with six manganese concentrations were used in the soybean experiment. Boron and manganese were used at five levels each in the corn experiment. Observations were made as to the development of toxicity symptoms. Boron, manganese, and iron were determined in the top leaves of the corn plants. Measurements of dry-matter production were made for both crops. Five parts per million of manganese was toxic to soybean plants and reduced yields, but toxicity was lessened by increasing the boron in the nutrient solution up to 0.5 p.p.m. Boron was toxic also at levels above 0.5 p.p.m. No definite manganese-toxicity symptoms developed in the corn plants. In general, high boron (2, 5 p.p.m.) reduced corn yields regardless of the manganese level. Chemical analyses of the corn leaves suggests the possibility that manganese accumulation may be modified to some extent by boron concentrations.

Previous Season

Field experiments on four sites over 3 yr evaluated the effect of banded and broadcast applications of fertilizer P, with and without application of Zn on the tissue concentration and uptake by the plant of Zn, P, Ca, and Mg in oilseed flax (Linum usitatissimum L.). Residual effects of the P applications were also evaluated over five site-years. Banded applications of P tended to be more effective than either broadcast applications or residual P in increasing tissue concentration and uptake of P. Zinc application tended to decrease P concentration in the tissue where P levels were relatively high. When Zn was applied with banded P applications, it tended to reduce P uptake by the plant; when it was applied with broadcast P, it tended to increase P uptake by the plant. Changes in P uptake in response to Zn application generally reflected changes in dry matter production. When an increase in Zn concentration in the tissue or uptake by the plant occurred due to Zn applications, it was primarily when the Zn was applied with broadcast P fertilizer or where P had been broadcast the previous season. The increase in uptake of Zn generally reflected increased dry matter yield. Banded applications of P tended to produce lower tissue concentrations of Zn than did broadcast applications. Zinc concentration in the tissue also tended to be reduced by residual P from applications the previous season. Changes in Ca concentration in the tissue and uptake by the plant generally reflected changes in dry matter production. However, Mg concentration in the tissue and uptake by the plant were increased by P applications, particularly where P was banded. The increase in concentration in the tissue and uptake of Mg by the plant with application of P indicates that applications of P increase the ability of the plant to absorb Mg, presumably due to an effect on the absorption-translocation system within the plant.
