“…However, there were no significant NH 4 + concentration in the soil solution in CS and PS (Fig. 1b), and approximately 70% of N present in liquid manure was in the ammoniacal form (Martínez et al 2017b).…”

“…These results suggest that the released of N by organic sources in the soil occurred mostly prior to the moment of higher N demand by corn. For this reason, it is interesting to combine the use of organic sources such as animal manure (before sowing) with the use of mineral N sources (top dressing), especially in grasses such as corn, in which split fertilization is recommended during the crop cycle (Ciancio et al 2014;Zhang et al 2016;Martínez et al 2017aMartínez et al , 2017b. The combined use of organic and mineral N sources is corroborated by the study of Guo et al (2016), who found that applying only 25% of total N recommendation in mineral form and 75% in organic form (manure) was enough to reach yields similar to treatments with 100% mineral fertilization.…”

“…The application of animal manure as a source of nutrients, especially nitrogen (N) for plants, is widely used in no-till cropping systems. Nitrogen in liquid animal manure such as pig slurry (PS) and cattle slurry (CS) is mostly found in ammoniacal form (NH 4 + and NH 3 ) and part in organic forms (Hernández et al 2013;Martínez et al 2017b). On the other hand, most N in solid animal manure such as pig deep-litter (PL) is in organic form (Sommer et al 2013) that is mineralized by the microbial population to mineral N forms such as nitrate (NO 3 − ) and NH 4 + in the soil solution.…”

The study aimed to evaluate the effects of long-term organic and mineral fertilization on soil solution dynamics of nitrogen (N), as well as to understand its relationship with corn plant growth, plant N uptake, and grain yield. The study was conducted in Santa Maria, State of Rio Grande do Sul, Brazil, for 12 years. The treatments consisted of pig slurry (PS); cattle slurry (CS); pig deeplitter (PL); mineral fertilizer (NPK); and no fertilization (control). We determined concentrations of dissolved inorganic N (DIN) and dissolved organic N (DON) in soil solution in situ, prior to sowing and during the growing cycle of corn. In plants, we determined the gaseous exchange, shoot N content, grain yield, and indices of recovery and efficiency of N. DIN in soil solution was the predominant N form in all treatments, ranging from 53 to 80% of total dissolved nitrogen (TDN). NPK was the only treatment that maintained high NO 3-concentration in the soil solution up to 35 days after plant emergence (DAE) and this resulted in higher grain yield. The plants fertilized with CS obtained a recovery of 80% of the N, and promoted improvements in crop growth. The results of this study showed the importance of combining the application of organic fertilizers (before sowing) with mineral sources of N (topdressing), allowing the maintenance of N availability in the soil solution during periods of demand of organic fertilizer.

It is great of importance to better understand the effects of the long-term fertilization on crop yields, soil properties and nitrogen (N) use efficiency in a rotation cropping cultivation system under the conditions of frequent soil disturbance. Therefore, a long-term field experiment of 40 years under soybean-maize rotation was performed in a brown soil to investigate the effects of inorganic and organic fertilizers on crop yields, soil properties and nitrogen use efficiency. Equal amounts of 15N-labelled urea with 20.8% of atom were used and uniformly applied into the micro-plots of the treatments with N, NPK, M1NPK, M2NPK before soybean sowing, respectively. Analyses showed that a total of 18.3–32.5% of applied N fertilizer was taken up by crops in the first soybean growing season, and that the application of manure combining with chemical fertilizer M2NPK demonstrated the highest rate of 15N recovery and increased soil organic matter (SOM) and Olsen phosphorus (Olsen P), thereby sustaining a higher crop yield and alleviating soil acidification. Data also showed that no significant difference was observed in the 15N recovery from residue N in the second maize season plant despite of showing a lower 15N recovery compared with the first soybean season. The recovery rates of 15N in soils were ranged from 38.2 to 49.7% by the end of the second cropping season, and the residuals of 15N distribution in soil layers revealed significant differences. The M2NPK treatment demonstrated the highest residual amounts of 15N, and a total of 50% residual 15N were distributed in a soil layer of 0–20 cm. Our results showed that long-term application of organic fertilizers could effectively promote N use efficiency by increasing SOM and improving soil fertility, and thus leading to an increase in crop yields. This study will provide a scientific reference and guidance for improving soil sustainable productivity by manure application.

“…Optimum SD vary from one environment to another [8]. In the Ebro valley, the month of April is the most recommended sowing period for maize, particularly, the first half of the month [20][21][22]. Even so, there can be year-to-year variations associated with temperatures and rainfall during spring.…”

Sowing Date Affects Maize Development and Yield in Irrigated Mediterranean Environments

Timely sowing is critical for maximizing yield for both grain and biomass in maize. The effects of early (mid-March), normal (mid-April), and late (mid-May) sowing date (SD) were studied over a three-year period in irrigated maize under Mediterranean conditions. Early SD increased the number of days from sowing to plant emergence. Late SD reduced the number of days to plant maturity, and had higher forage yields, higher grain humidity, and taller plants. The average grain and forage yields achieved were 13.2 and 21.3 Mg ha−1; 14.0 and 25.1 Mg ha−1; and 12.8 and 27.6 Mg ha−1, for crops with early, normal, and late SD, respectively. The data support the general perception of farmers that April sowings are the most appropriate in the area where the experiments were carried out. Early SD resulted in lower population densities, while later SD did not yield (grain) as high. However, late SD produced taller plants that contributed to achieve higher forage yields. Late SD could be interesting for double annual forage cropping systems. Sowing at the most appropriate time, when the soil is warm, ensures a good level of maize grain production. Future research could focus in the effect of SD for total annual yields in double-annual cropping systems
