“…With increased N uptake by the plants, the concentration of N forms in the soil solution is expected to decrease. This is desirable because it reduces the risk of leaching (especially of NO 3 − ) since this ion forms outer sphere complexes with functional groups of soil reactive particles (Choppin 1997;Saka et al 2017). It also reduces loss by volatilization, especially if the pH of the soil solution is high (Monaco et al 2012) and even by denitrification at anaerobic soil sites (Zhang et al 2015).…”

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.

“…These results offer compelling evidence in November by representing lower TN on peak rainfall than on early October and end of December rainfall events (Figure 2). In addition, the amendment of manure or leguminous crops can increase TN availability by enhancing the mineralisation rate naturally, and sustainability will protect the soil surface (Hua et al, 2020;Saka et al, 2017;Stagnari et al, 2017). Sharangi (2011) proved that a 25% farmyard manure mixture with 75% urea has a promising effect on the black pepper crop.…”

This study was conducted to determine the effect of the rainfall pattern on cation nutrients in black pepper cultivation in a hilly topography. A field study was conducted in black pepper cultivation in a hilly topography around Bintulu, Sarawak, Malaysia, with a 26o slope during the Northeast monsoon in 2020. Six blocks were established on 462.56 m2, with four subsequent soil samples (0-20 cm) collected per block after the rainfall. Soil samples were analysed using the standard pH, total organic carbon (TOC), soil texture, total nitrogen (TN), available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), and manganese (Mn) in triplicate. Rainfall pattern (October < November > December) affects TN (300.31-1422.90 mg/kg) and K availability (13.54-166.68 mg/kg), especially during peak season in November 2020. Available P, Ca, Mg, Fe, and Mn exhibit minimum rainfall effect but are closely related to combined interaction with parent material and topography. Therefore, proper soil management, such as applying fertiliser using top dressing, foliar spray, and manure amendment, including growing cover crop, is recommended to improve nutrient availability.

“…Hence, in order to predict the net mineralization of nitrogen in animal manures, transformation of nitrogen from organic into inorganic form and immobilization processes need to be understood (Saka et al 2017) since these processes are mediated through microbial activities and could be biochemical (Vel and Swarnam 2013).…”

Purpose The study evaluated dried manures and manure ashes as alternative products from animal manures, and determined the dynamics of soil nitrogen availability indices and organic carbon release in some soils amended with dried manures and ashes under laboratory incubation, screen-house and field experiments. Methods Cattle, goat and poultry manures were collected and air dried to produce dried manures after which part of the dried manures were burnt in open space at a temperature range of 320-450 °C to produce manure ashes. Treatments which were no amendment (control), dried manures of cattle, goat and poultry manure ashes of cattle, goat and poultry and NPK 15-15-15 at 120 kg N ha −1 were applied to soil. Samples were taken fortnightly after amendment incorporation in the incubation experiment; in screen-house experiment and field experiments, plant seeds were established after amendment incorporation; thereafter, soil samples were taken fortnightly. Soil samples were analyzed for soil organic carbon (SOC), NH 4 +-N and NO 3 −-N using a spectrophotometer. Results Incineration of manures increased pH, exchangeable cations and carbon, while nitrogen in manures ashes was comparable to nitrogen in dried manures. The application of manure ash increased SOC, NH 4 +-N and NO 3 −-N by 182, 102, 128% in incubation experiment while 64 and 628% increase in SOC and NH 4 +-N was recorded in screen-house experiment, respectively, relative to the control. In the field experiment, a significant increase in NO 3 −-N was recorded at the onset of incorporation; nitrification was more pronounced than ammonification under incubation and field conditions. Conclusion Dried manures are not superior to manure ashes and incorporation of manures ashes increased the SOC, NH 4 +-N and NO 3 −-N though changes with increasing weeks were erratic.
