“…Nitrogen inputs and residues in the soil are high in greenhouse vegetable cultivation ecosystems [49]. Slow-release fertilizer can increase soil availability of N, the development of the root system, and nutrient absorption capacity of rapeseed (Brassica napus L.) [50]. In the present study, for two consecutive years, the amounts of N, P, and K that were removed through the harvest of Chinese chives of the SRF treatment were significantly higher than those with CF treatment.…”

Excessive application of fertilizers leads to the loss of a high amount of nutrients and low fertilizer utilization, which severely restricts crop productivity. Establishing better fertilizer usage practices can mitigate the adverse effects of excessive fertilizer use in agricultural practices. This study determined the effects of slow-release fertilizers on the growth; quality; root and nitrate reductase activity; accumulation; distribution of nitrogen (N), phosphorus (P), and potassium (K) in roots, stems, and leaves; and NPK utilization of winter Chinese chives (Allium tuberosum Rottler ex Spreng.) in multi-layer covered plastic greenhouses. Treatments were conventional fertilization (CF, NPK: 1369.5 kg ha−1), conventional fertilization with slow-release fertilizer (SRF, NPK: 1369.5 kg ha−1), reduced fertilization with slow-release fertilizers (SRFR, NPK: 942.0 kg ha−1), and no fertilizer arranged in a completely randomized design with three replicates. The SRFR treatment increased Chinese chives yield and economic profitability by 37% and 47%, respectively, compared to the CF treatment. Similarly, nitrate reductase activity, root activity, soluble sugar, soluble protein, and flavonoid contents in the Chinese chives were increased by 40%, 12%, 16%, 6%, and 18%, respectively, in SRFR than CF. In addition to these, we observed a significant reduction in the surplus of N (42%) and P (58%) in soil under SRFR compared to CF. Nutrient uptake and nutrient use efficiency were also greater in SRFR than in CF. The results indicate that the adoption of SRFR can be an efficient approach to enhance quality and productivity of Chinese chives compared to CF under a multi-layer covered plastic greenhouse system.

“…The increase in height of A. fruticosa was greatest at W3, except for F2, indicating that the water-retaining agent improved water use efficiency [34]. The levels of water and fertilizer affect plant growth, particularly branch number [35]. At the highest levels of water-retaining agent (W5), the branch number was greater for each fertilizer level than that for other levels of water-retaining agent.…”

The number of road engineering and construction projects that create rock slopes has been increasing year by year, instigating a series of geologic hazards and ecosystem destruction such as landslides, mudflows, and so on. The ecosystems are thus in an urgent need for recovery and reconstruction. However, ecological restoration processes of rock slopes are more challenging compared to those of clay slopes because rock slopes are highly heterogeneous and do not provide favorable soil conditions for plant growth, especially due to the lack of nutrient accumulation and lower heat and moisture capacity [1]. Thus, rock slopes present complex and varied ecosystems that do not support plant growth.Pol. J. Environ. Stud. Vol. 27, No. 6 (2018), 2821-2832 AbstractWe investigated substrate material and the effects of different fertilizers and water levels as variable factors for slope restoration. A field rainfall monitoring experiment was carried out to explore morphological changes in Amorpha fruticosa L., the water-holding capacity of its leaves under different water and nutrient gradients, and the nutrient losses from the substrate. The results showed that nutrient loss by runoff was significantly affected by fertilizer use and they increased with the increased application of fertilizers. The concentration of nitrogen in runoff was insignificant, the concentration of phosphorus was increased, and the runoff concentration of potassium was decreased after increasing water-retaining agent levels in the substrate. The concentration of nutrients in runoff from rainfall generally followed a trend of slight fluctuations, then a rise, and finally a decrease. The addition of F2 fertilizer produced the lowest nitrogen losses from substrate material and reduced the leaf area where the addition of phosphate fertilizer had a significant effect on crown diameter. At greater content of the water-retaining agent, the water in substrate material increased, resulting in increased water absorption by the plants and increased relative water content of leaves. Ultimately, W3F4 was the most favorable combination of water-retaining agent and fertilizer concentration for plant growth, which may be related to runoff losses. This combination provides optimal conditions under which the plant can maintain a perfect balance of nutrients and thus improve plant growth indices.

“…Thus, technologies that minimize the requirement of soluble fertilizers (SF) are drawing increasing attention. In this context, control release fertilizers (CRFs) can reduce the use and requirement of SF by substantially preventing the losses (Tian et al, 2016). Various carriers or coating materials like coal, biochar, peat, bentonite, alginates, chitosan, nonbiodegradable polymers, and so on, are used for the development of slow release formulations or sustained release fertilizers (SRFs) (Calabi‐Floody et al, 2018) and most of them are reported to be in coarse form.…”

Slow release nanofertilizers are of interest for reducing soil nutrient losses and preventing land degradation associated with established fertilizer use due to use of fertilizers. Chitosan nanoparticles (CN) were prepared following polymerization of chitosan with methacrylic acid and later incorporated with potassium (CNK). CN as well as CNK were characterized using Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy, field-emission scanning electron microscope, and atomic force microscopy (AFM) techniques. The slow potassium release property of CNK was elucidated employing membrane diffusion studies. Zea mays plant were tested in pot trials using different doses of K-formulation with potassium incorporated or otherwise and compared with suitable controls. Soils amended with reduced potassium rates (75% CNK) significantly increased the fresh-and drybiomass accumulation by 51 and 47%, respectively, in relation to positive control (100% KCl). The use of 75% CNK improved physical properties of soil by way of enhanced porosity, higher water conductivity, and enhanced friability that favoured root growth. These along with reduced dry density induced the plants to uptake higher quantities of nutrients and develop double the root biomass relative to control. Further, no deleterious effect of the nanoformulation was apparent and the treatments showed better carbon-cycling activity. Increased fluorescein diacetate (FDA) hydrolysis in these treatments demonstrated higher soil microbial activity in relation to control. CNK was hypothesized to condition the soil by cohesive bonding of soil particles, stabilizing the soil aggregates by coating them, and preventing their degradation amidst disruptive forces such as repeated watering. Sustained nutrient release synchronize with crop demands, reduced fertilizer requirement and increased productivity.
