Treatment Application

Macadamia growers have responded to increasing soil acidity in plantations by applying ameliorants, but optimum pH for production has not been identified. The effects of lime applications on the growth, yield and leaf composition of macadamia (Macadamia integrifolia Maiden and Betch) trees were investigated at each of two sites (Pomona and Cootharaba) with acidic sandy soils in south-east Queensland. Trees at the Pomona site had been established for 6 years whereas, at Cootharaba, the trees had been recently planted. The effects of annual applications of nitrogen and nitrogen plus lime were also studied at the Cootharaba site. Tree parameters and soil properties were monitored each year for 5 years after treatment application in 1988. Treatments resulted in pH (water) values ranging from 4.6 to 7.5 and 4.3 to 6.5 at the Pomona and Cootharaba sites, respectively. with a concomitant range in soil Ca and A1 levels. Despite the wide range in soil properties, lime had no significant (P < 0.05) effect on nut-in-shell yield in any year, and the results suggest that macadamia is relatively tolerant of soil acidity. However, yields from treatments with pH values greater than 5.5 tended to be lower than those with more acidic pH values, suggesting that overliming may adversely affect long-term productivity. High lime rates also resulted in a marked reduction in the number of proteoid roots. At the Cootharaba site, nitrogen treatments significantly (P < 0.05) increased nut-in-shell yield despite the juvenile growth stage of the trees precluding nut yield until the 1993 season. Although lime applications at the Cootharaba site resulted in some increase in leaf Ca concentrations, treatments at the Pomona site, with older trees, had little effect on leaf nutrient composition.

P Fertilizers

In calcareous soil, the significant portion of applied phosphorus (P) fertilizers is adsorbed on the calcite surface and becomes unavailable to plants. Addition of organic amendments with chemical fertilizers can be helpful in releasing the absorbed nutrients from these surfaces. To check out this problem, a field experiment was conducted for two years to determine the effect of P fertilizers and humic acid (HA) in enhancing P availability in soil and their ultimate effect on growth, yield and P uptake of wheat in calcareous soils. The experiment was comprised of five levels of P (0, 45, 67.5, 90 and 112.5 kg P2O5 ha−1) as a single superphosphate (SSP) and 2 levels of locally produced humic acid (with and without HA) arranged in a two factorial randomized complete block design (RCBD) with three replications. Wheat plant height, spike length, number of grains per spike, 1000-grain weight, grain, straw and biological yield were significantly improved by the addition of HA with SSP. Very often, the performance of 67.5 kg P2O5 ha−1 with HA were either similar or better than 90 or even 112.5 kg P2O5 ha−1 applied without HA. Post-harvest soil organic matter, AB-DTPA extractable and water-soluble P, plant P concentration and its uptake were also significantly improved by the addition of HA with SSP compared to sole SSP application. It was evident that P efficiency could be increased with HA addition and it has the potential to improve crop yield and plants P uptake in calcareous soils.

The Impact

Two field experiments were conducted in a calcareous soil during summer seasons of 2019 and 2020 at the experimental in a private farm Mallawi, El- Minia Governorate, Egypt to evaluate application of K fertilization at different rates of K2SO4 and non-classic products, i.e. K feldspar, mixture with or without inoculation with the K dissolving bacteria (Bacillus circulans.) soil chemical properties, plant growth, yield and nutritional value of corn (Zea-maize hybrid third 310). Our results proved that inoculation of maize seeds with Bacillus circulans at rate of 36% K2O improved soil pH, EC, soil organic matter content and enhanced the soil available N, P and K concentrations. Also, the growth parameters, yield and nutritional status of the plants were significantly increased by using non-traditional potassium fertilizers particularly in the case of seed inoculated with potassium dissolving bacteria (Bacillus circulans).
