A Rhizogenic Biostimulant Effect on Soil Fertility and Roots Growth of Turfgrass

The excessive use of chemical fertilizers can lead to severe environmental damages. In recent decades, the application biostimulants improve soil composition and stimulate plant growth has contributed significantly preservation. this paper, we studied effect a rhizogenic biostimulant, obtained from fulvic acids, probiotics, prebiotics, on fertility two types soils, sandy loam in which turfgrass was growing. Soil samples plots treated with biostimulant controls (untreated plots) were collected. analyzed parameters include organic matter, microbial activity, composition, catalase, dehydrogenase, phosphatase enzyme activities. Moreover, root lengths examined compared species. improved enzymatic activity both soils. calcium, potassium, magnesium, phosphorus content increased application, whereas pH electrical conductivity decreased. most relevant improvement 77% increase calcium for 38% potassium soil. Biostimulant led significant turf length. This greater than an increment 43% 34% respectively, control.
