“…Ca concentrations during the incubation time (Fig. 5a) increased at 7-day with the use of LM, PG, CF and PL, but it showed a sharp decrease in LM between 56 and 112 d. These changes over the time have been reported by Hirzel et al (2016) for short incubation times with different calcium fertilizers in two soils of loam and clay loam texture.…”

Organic food production has increased the demand for organic supplies in agriculture. Organic fertilizers are known to have an effect on crop and soil properties, but this effect has been little studied. This research evaluated the effect of seven nitrogen fertilizers allowed for use in organic production and one conventional fertilization treatment adjusted to a similar dose of total nitrogen (N), on chemical properties of two soils of contrasting physicochemical properties (sandy loam Mollisol and silty loam Andisol) incubated under aerobic conditions and controlled 6 times over 112 d. Treatments were: Compost (CO), Fertil (F), Purely Grow (PG), Purely Lysine (PL), Blood meal (BM), Lupine meal (LM), Sodium nitrate (SN), conventional fertilization (CF), and a control without fertilization (CT). The experiment was conducted in a split-plot design for each soil. The results showed that the fertilizers affected soil pH, salinity (electrical conductivity, EC), and the concentrations of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S). In general, the highest values of pH, available P, and exchangeable K, Ca and Mg were obtained using CO in both soils, whereas PL reported the lowest values for most parameters evaluated. The evolution of each parameter over time showed interactions with the fertilization treatment, with a steady decrease in pH and an increase in EC in both soils. Differences in the average values of chemical properties during incubation with respect to their initial values were related to the physicochemical and organic characteristics of each soil.

The excessive and inappropriate use of synthetic fertilizers has the potential to cause significant environmental and economic issues. The utilization of biofertilizers represents a sustainable and environmentally friendly alternative for the enhancement of crop productivity. Accordingly, the present study evaluated the productive and economic behavior of applying biofertilizers on hybrid corn DAS 3383 under a completely random block design, with five treatments and three repetitions. The following treatments were employed: a control treatment devoid of any fertilization (CONTROL), a conventional treatment comprising NPK fertilization (NPK), a treatment incorporating 5 % biofertilizer (5BIO), a treatment incorporating 15 % biofertilizer (15BIO), and a treatment incorporating 25 % biofertilizer (25BIO). At the 90-day mark, the NPK treatment exhibited the greatest plant height (272.81 cm), while at the 108-day interval, the cob insertion height (170.40 cm) was also the highest. However, the 25BIO treatment yielded the most optimal results in terms of cob length (14.29 cm), diameter (6.07 cm), 1,000-grain weight (31.70 g), and yield (9 t.ha-1). This treatment also demonstrated the highest net benefit ($2,019.10) and favorable profitability (72 %) compared to the other treatments. The results of the orthogonal contrast analysis indicate that there are significant linear effects for the majority of variables, with no discernible quadratic effects. This evidence substantiates the potential of biofertilizers in enhancing maize crop productivity. By repurposing organic waste from the agricultural sector and employing it as an alternative to chemical fertilizers, these findings contribute to the advancement of more sustainable and profitable agricultural practices. Keywords: organic fertilizer, genotype, seed, organic waste, profitability.
