The Effect of Soil Conditioners on Cellulose, Hemicellulose, and the Adl Fibre Fraction Concentration in Dactylis Glomerata and Lolium Perenne

Abstract

Replicated three times, the research was conducted in the experimental field between 2011 and 2014. Three soil conditioners with the following trade names: UGmax, EkoUżyźniacz, and Humus Active Papka were used in the experiment, separately or together with NPK fertilisers. They were all used on plots sown with two species of grass, Dactylis glomerata of the Bora variety and Lolium perenne of the Info variety. The plant material from both grass species was tested for the concentration of ADL fraction (% DM), cellulose (% DM), and hemicellulose (% DM). It was found that the concentration of cellulose, hemicelluloses, and the ADL fraction was significantly higher in the biomass of Dactylis glomerata than in the biomass of Lolium perenne. The grass from the plot with the UGmax soil conditioner applied had the highest amount of cellulose and hemicellulose. The lowest amount of those organic compounds was found in the grass treated with UGmax together with mineral fertilisers and in plants treated with Humus Active, together with mineral fertilisers. However, the fertilisers and conditioners did not increase the ADL content in both grass species.

Effect of slurry used with soil conditioners and fertilizers on structural, non‐structural carbohydrate and lignin content

“…Additionally, Ciepiela (2014) found in her studies that the Kelpak biostimulant increased the hemicellulose content of Festulolim braunii, but an interaction of this product with N resulted in a decrease. In addition, Ciepiela (2014) and Truba et al (2017) recorded the lowest hemicellulose content in the first growth cycle, but the results obtained in the present studies showed that the differences were not statistically significant.…”

“…The trend of changes in cellulose amounts across harvests in Ciepiela's (2014) studies was confirmed by the results of the present experiment as its highest content was recorded in the first harvest and the smallest in the third. In the studies of Truba et al (2017) soil conditioners used on their own also increased cellulose content, but mineral fertilizers reduced it. Weather conditions in both growing seasons, not conducive to the proper growth and development of grasses, were also of great importance for the formation of cellulose content.…”

“…The highest hemicellulose content was recorded in grass from plots treated with slurry supplemented with UGmax and significantly lower when slurry was applied T A B L E 5 Lignin content in the dry matter of Festulolium braunii (g kg −1 ) on its own. According to Truba et al (2017), the highest hemicellulose content was in grass treated with the UGmax soil conditioner, while the use of Humus Active together with NPK fertilizers resulted in its lowest concentration in plants. Additionally, Ciepiela (2014) found in her studies that the Kelpak biostimulant increased the hemicellulose content of Festulolim braunii, but an interaction of this product with N resulted in a decrease.…”

“…An undoubted advantage of slurry as a fertilizer is its significant content of nutrients (especially N) in available forms, while its disadvantage is large losses due to the leaching of the nitrate form (Christensen et al, 2009;Kall et al, 2016;Oenema et al, 2001). Research involving soil conditioners has proven their beneficial effect on the quality parameters of forage grasses and lawn turf (Jankowski et al, 2019;Sosnowski et al, 2013;Truba et al, 2017), although few authors do not unequivocally confirm their significant positive impact on the nutritional value of grasses (Ciepiela, 2014;Ciepiela & Godlewska, 2015). Due to climate change, causing an increasing water scarcity in the soil, Festulolium braunii (K.…”

The Effect of Soil Conditioners and Weather on Lawn Appearance

“…Sosnowski (2012), applying both UGmax and mineral fertilizer, observed that Lolium perenne responded with a significant increase in the number of shoots, leaf lamina length, leaf base width, and leaf greenness index. Additionally, Truba et al, (2017), also in an experiment with Lolium perenne, found the lowest biomass increase when Humus Active Papka was applied on its own. In the present experiment, comparing the effects of the soil conditioners on all grass species, UG-max and Substral had the highest impact on lawn appearance (7.9 o ) and Humus the lowest (6.4 o ).…”
