“…The treatments containing HA alone and HA þ biofertilizer showed significantly higher greenness and vigor values at V10 and tasseling. The same study mentioned previously from Zhu and Li (2018), showed that the highest application rate of HA consistently had higher values of visual turf quality than the control from May through September in Colorado and North Dakota. In this case, the turf grass visual quality assessment followed the (Morris and Shearman 2000), which included color and plant density as criteria to grade the treatments.…”

“…The application of HA alone significantly increased NDVI values only at tasseling, but the combination HA þ biofertilizer resulted in NDVI values significantly higher than control at V10 and Tasseling (Table 5). Zhu and Li (2018) compared the application of two rates of HA against the control (without HA) on turf grass in Colorado and North Dakota and found that HA significantly increased NDVI values at both rates and locations. Also, when comparing to control, HA applications resulted in higher NDVI from May through September, but this was only measured at V10 in 2017.…”

Current trends in agriculture have moved toward more sustainable cultivation systems with higher efficiency of input use. A variety of materials, derived from different resources, can serve as a crop nutrient sources. An Integrated Plant Nutrition System (IPNS) uses the combined and harmonious use of inorganic, organic and biological nutrient resources to maximize efficiency of inputs. We evaluated the effects of commercial nitrogen (N) fertilizer, humic acid compounds (HA), compost/manure teas and bioinoculants as inorganic, organic and biological resources, respectively and their synergy over three years on corn (Zea mays L.) in the Mid-Atlantic USA. The individual and combined application of HA and biofertilizer following the IPNS influenced corn height and leaf greenness to varying degrees, most likely due to biostimulant effects. In 2017, corn height, NDVI, greenness and vigor responded positively to biostimulant application to varying magnitudes and growth stages, however grain yield and nutrient content were not affected. In combined studies from 2018 and 2019 corn height was not impacted by biostimulant application but NDVI, photosynthetic efficiency, greenness and vigor were increased at different doses and corn growth stages. The combined use of HA þ biofertilizer (Microlife Humic þ Microgeo) was the only treatment leading to increased grain yield. This study demonstrates that the individual and combined application of HA and biofertilizer can influence corn growth and vigor at various points during the growing season. However, the current study cannot conclusively confirm that the integrated use of HA and biofertilizers (IPNS) is a better practice than the application of each compound individually.

“…Soil salinity was within the norm (<1 g•dm -3 ), and it did not limit the growth of grass. In a study by Zhu and Li [20], the application of humus in a sports field reduced soil salinity, increased microbial biomass and improved sward quality. The organic matter content of soil ranged from 3.43% to 6.55% and exceeded the norm for sports fields according to DIN 18035-4 criteria ( Table 3).…”

Our study was conducted in 2013-2017 on the main sports field of the Department of Physical Education and Sport of the University of Warmia and Mazury in Olsztyn. The examined field was established in the 1950s. The following sward characteristics were evaluated on a 9-point scale in accordance with the methodology recommended by the Research Center for Cultivar Testing (COBORU): overwintering success (spring), density, color and the overall quality of the sward (spring, summer and fall). The species composition of the sward, plant health, functional characteristics of the sward, and soil compaction were also determined. An increase in soil compaction, a decrease in the sward's functional characteristics and changes in the species composition of grass were noted after five years of field use for various disciplines of professional sports. The sward was characterized by varied overwintering success, high density (particularly in summer), green and fresh green color, very low prevalence of fungal diseases, and satisfactory or good visual merit. The proportion of Lolium perenne L. decreased, whereas the proportions of the undesirable species Poa annua L. and dicotyledonous weeds increased in the analyzed sward. The condition of the evaluated sward was influenced by loading (field exploitation), increased soil compaction, and deterioration in the physicochemical properties of soil, as well as the applied maintenance treatments and weather conditions during the study.

Evaluation of Humic Fertilizers on Kentucky Bluegrass Subjected to Simulated Traffic

Sports field traffic tolerance is critical for offering athletes a safe playing surface and adequate turfgrass performance. Humic substances act as bio-stimulants that could enhance turfgrass traffic tolerance by increasing turfgrass efficiency, which could be due to increased root growth, antioxidant activity, and/or physiological health. A two-year field experiment was conducted on a Kentucky bluegrass (Poa pratensis L.) sports field to investigate if incorporating humic substances with fertilizers could improve turfgrass traffic tolerance and performance, and enhance turfgrass recovery after traffic. Treatments included humic-coated urea, poly-coated humic-coated urea, synthetic fertilizer with black gypsum (two application timings), black gypsum, stabilized nitrogen, poly-coated sulfur-coated urea, urea, and a nontreated control. The addition of humic substances to fertilizer treatments did not result in improve traffic tolerance and performance. Fertilizer treatments did not lead to an effect on soil moisture, surface hardness, and shear strength. Turfgrass recovery varied between years. In 2020, the second year of the experiment, four applications of fertilizers increased turfgrass recovery by 136% relative to the nontreated. Furthermore, incorporating humic substances did not result in enhanced turfgrass recovery compared to fertilizers alone. Overall, applications of fertilizers with humic substances could improve turfgrass recovery from traffic compared to fertilizers alone, but results were variable between years.
